I am anouncing a new product. It is a metal case for the G540. The case is CNC machined to work with the G540. I have included a cutout for a fan if needed for heavier loards and big power supplies. See the product section for details


August 21,2008

Sorry for not keeping the web site up to date. The prices for some of the items listed have risen due to commodity price increases that have to be passed on. MCG has changed their policy for stepper motors and now require a 100 pc order from me. Additionally MCG was bought out by Ametek. Their existing policy on stepper motors doesn't apply to servo motor. I have also made several other changes and updates to the web site.


I have updated the list of servo motors I can and addded them to the product section. I also had to change the pircing on S/H because of significant increases is transportation costs.

March 15,2006

I have moved most of my stuff to www.camtronics-cnc.com . I have added 3D software to my list of products.

I received 40 new 430 oz in Moog ( made in the USA ) servo motors used by Jeff Davis on mill/drills, Sieg X3 and popular 3/1 machines that are cnc ready

September 27, 2005

Sold out the linear stepper motors. The new XP driver is being tested and looks good so far. Maybe ready in two weeks.

Updated and deleted a lot of products that were discontinued or sold out.


Septermber 5, 2005

The 3d scanner has been put on hold until the video driver for XP is fixed. I have no date when it will be done.


August 8,2005

Discontinued the sale of the Tachomter kits due tro slow sales and I ran out of printed circuit boards.

Added the Haylon linear stepper motor


June 4,2005

Case are back in stock.

The 3D scanner should be availble around the end of June

The 3D scanner should be availble around the end of June

April 17,2005

My new web site is up and running at  http://www.camtronics-cnc.com  .The CP250 servo motors went fast and have been sold out. My Tree mill is pretty well finished and running quite nicely. I am still out of cases for the G201/210/g320/g340 drives. I hope to have them back in stock in a week. I have received most of the part for the 3D scanner kits but am awiting technical documentation. The revised market date is 4-30-05

March 26,2005

I have signed the license agreement and have started ordering parts for a new product which is the first low cost 3D scanner kit. It can scan an object in 45 seconds. I will post a picture of one of the resulting scanned objects in the image section. I should have kits availble around April 11,2005. I think these are going to be a real hot seller and will be a new technology available to the small shop/home, business for under $500

I have added some nice PMDC servo motor in the product page of my web site.Real nice for plasma cutters and minimills

I am nearly done with the Tree Mill Journeyman 300 retrofit. It's been a interesting and fun project. I just have a few details to finish. I then need to decide if I will repaint it. I am more for the functional use than the appearance.

“The finest stepper motor I ever tested.” Was what Mariss at Geckodrive told me when he tested a new motor that I am now carrying in my product list.

Several months ago my distributor told me that they were going to discontinue carrying the MAE Italy made stepper motors and would start ordering them from Asia. When they arrived I ordered a few to test. These motors are of the square body design 8 wires and dual shaft. I was really surprised that the 452 oz in bipolar rating of the motor was in such a short package. It looked like a single stack NEMA 34 motor. Even more interesting was that the motor shaft when turned by hand was much smoother than any other motor I had ever tested or ran.

            I was calling an order into Gecko drives and after placing the order I asked to talk with Mariss about the new motor knowing that he has a good dynamometer and is eminently qualified to give an unbiased opinion of the performance. When I talked with Mariss he indicated that he would love to test new motors.

             I shipped Mariss the 1h34110/103 motor and a few weeks later I called to see what the results were, “The finest stepper motor I ever tested.”  Mariss said he would email me test result which show that the power curve is almost linear from 500 RPM up to 3000 RPM when using a 42V 6A power supply. The curve shows the power at 116W at 500 RPM to 120W at 3000 RPM. These results were so good that in a further discussion the mentioned that he would like to test a NEMA 23 motor since most of his customers use that size motor. I shipped him one of my 23114 dual shaft motors. He is using that to test various drives and the results are expected to me no less stellar than the above.

 I will be carrying NEMA 23 motors with both single and dual shaft with torque ratings of 157 oz in up to 258 oz in bipolar, 8 wires. The nema34 motors with also be dual shaft but the rear shafts are .250 and the rear housing is drilled for an encoder. The torque range is from 452 oz in to 1303 bipolar, 8 wires. The best part is that my pricing will be most likely lower than most other dealers.


October 13, 2004

I hope to update the information portion of my web site in the next few weeks with some tips on buying an Ebay used CNC milling machine. The article will cover everything from the preparations for bidding to the transportation across contry to my Shop. Last it will cover the retrofitting process.

Updated Octtober 11. 2004

I removed the Clifton motors and the electrocraft motors from my list as they were all sold out. I updated the list of stepper motors that are clearance iems. Added the Pittman servo motors.

More motors are coming in. I should be receiving a batch of stepper motors this week. Various torque but most of them are the 1076 oz in range. I also received 50 Hitachi servo motors. These jewels would be great for direct drive of a sherline or even perhaps a taig. They have a 500 PPR encoder. The motorsa are rated at 22.5 volts but should run fine all the way up to 36VDC. The motors have a C23 frame 2.103DX4.6"L. The shaft is .1965 or 5mm D X.875L. I have run one on a gecko drive at 36V and it was awesome. Best yet is the price. Only $34.95 each plus $5 per motor s/h.


August 15, 2004

I have only 1 left of the is34-028, 2 left of the 34-027's and six left of the 34-026.

I have a few motor odds and ends coming in. I also acquired 50 Hitchi C 23 frame servo motors with 500 PPR encoders. These motors run great with the desknc servo setup and the gecko drives. Really low price. great for the sherlines and proxxon mills.



July 24,2004 Another fantastic stepper motor sale is coming up in about a week. I have just purchased a shipment of 22 785 oz in, 15 of the 802 oz in and 6 of the 692 oz in stepper motors. All are new. All have dual shafts, All have 8 wires. They should arrive about July 30. Once I have the tracking information, I will start taking orders.. These motors retain at over $153 but my price will be around $85 each depending on the motor.

All of the 280 oz in motors were sold>

I will soon have a parallel port booster for those people using marginal voltage levels on their notebook/desktop PC's. As always the pricing will be much lower. It will provide a rock solid 5 VDC for step and direction lines. It connects directly to the parallel port at the back of the PC so it will drive long cables and improve pulses to your drivers.

July3, 2004

I have sold all by three of the 280 oz in motors. They sure went fast. I have added the 34-023 521 oz in stepper motors to my list of motors.

Watch this page for a new servo system that "rocks" with awesome features.

June 23, 2004

I have sold the last of the 1076 oz in stepper motors. They went fast and so are the IH34-011's

The 280 oz in motors are also selling fast:

June 4, 2004

I have ordered a large batch of nema23, 6 wire 282 oz in stepper motors. The motors have 200 CPR quadrature encoders but can easily be removed exposing a 5mm end shaft for use with a handwheel. These motors are new. They run great with XYLOTEX 2.5A drivers and the Famous Gecko drives. Specs are ~3A bipolar series but run great at 2.5A, motor voltage is 2.2.  I have advertised these on various news groups and there is a lot of interest in them and they will go fast. Great for use with Sherline, Taig and mini/micro- mills and lathes. With encoder $45 plus $6 s/h in USA. $40 w/o encoder plus $6 s/h

I have gotten out of the hospital and and slowly resuming operations. Recovery is going well so far. I will be opening limited sales in the next few days.

April 3, 2004

Due to a serious medical condition that requires surgery, I will be closing Camtronics Inc for about 2-6 weeks starting April 5. Hopefully the surgery will go well. The good news is that I have located a large source of stepper motors and power supply that will be priced  ridiculously low but that will have to wait until I can get moving around again. Dan

1 March 2004

Finally got around to partially updating the secrets of CNC.

I also have a special on the 23-025 210 oz in stepper motors. I only have a limited quantity but I think I can get more at a great price. Of course I pass on this savings. I wouldn't list it on my product page but I will be selling these dual shaft motors which are great for Sherline, Taig and Maxnc machines for only $79 plus $7 per motor s/h until my source runs out. I currently have them in stock

November 16, 2003

The cases for the G210 and G320 are finally starting to drizzle back into stock. I received 5 of the 20 I had on back order but they tell me that I should soon have my full order.

Oct 30, 2003 The st1500 are all sold out.

October 3, 2003

The E540 motors as well as the worldservo brushless motor and the kollmorgen motors are in stock. Added the 692 oz in 34-025 692 oz in motor to my list of stepper motors at a great price. Am having problems getting cases for kits and assembled units.

September 17, 2003

Done with my Vacation.  I now have the  Brushless servo amps programmed to make the setup quite simple compared to an unprogrammed servo amp. See the product page for detail and pricing.

I have added several additonal PMDC servo motors and added the 34-011 692 oz in stepper motor to the list of products. These will sell fast.

September 7, 2003

ON Vacation from September 8-15


August 20, 2003

I have acquired some awesome step and direction brushless servo drives and some Kollmorgen  brushless servo motors. I bought a batch of these at a good price and will be selling them at a good price. The servo drive are made by Worldservo model SST-1500 with a list price of $541 each but I will sell them for much, , much less. They are new and I will preprogram them to be as fully configured as possible without being on the machine. The servo amps are rated at 11A continuous with heatsink and fan. 23A peak. These drives are AWESOME! They were made as direct replacement for stepper drivers and work terrific with spendy Kollmorgen motors. Again their price as I recall was $850 for the 792 oz in (.9 HP) Nema 34 frame brushless motor that can replace any double stack standard nema 34 servo motor. My price will be ridiculously low. I want to sell these as a matched pair but will sell the drive seperately. I also acquired some Kollmorgen 1.1 HP servo motors that sell for well over $1000 each and again will sell them for a very low price. All motors are new, all servo drives are new. http://www.motionvillage.com/products/product_literature/product_brochure/pdfs/silverlinedp.pdf check out the H344 and H348 model motors. For the servo drive click on the link http://www.worldservo.com/dnload/WS%20SSt%20System%20Manual%2030.pdf

Each drive will be preconfigured ( unless the customer doesn't want it) to match the servo motor ordered. A link to the two web sites above will be provided as well as a link to the software for changing and tuning the servo drive. Additonally, with each drive I will provide the matching connectors and pins for fast installation. I will receive the above in about a week and don't expect them to last long. This is your change to get rid of the resonance plaqued, step losing system and replace it with a awesome state of the art brushless servo sytem and a dirt cheap price. Email me at dmauch@seanet.com for pricing,

Corrected the price on the Globe PM DC servo  motor with encoder listed below.

Is there any interest in Brushless servo motors and controllers?

My supplier or NEMA 34 stepper motors has indicated that many of the common ones that I sell are harder to get and may not be availble. Please check availability before ordering.

December 23, 2002

I have several different size PMDC servo motors that are now listed on the product page.

1.  New!  Globe motor  24VDC 1.5"D 2.25 L. Shaft has a ML style timing pulley. Has a HEDS 5505 A encoder which should mean that it is a HP/Agilent encoder 500 CPR  two channels and draw 35MA. No other motor performance data is available but these would be great for using as a DRO since the motor would act as a support bearing for the encoder. $25 plus $4per motor shipping

2.  Used Electro Craft 24VDC PMDC ball bearing supported shaft .375D .75L, motor is 2.2DX5.5L with renco encoder.  I will provide more data later. $39

3. NEW! electrocraft 240 oz in peak PMDC servo motor. Run at 3770 RPM at 28V. Max terminal voltage is 60VDC max current before demagnization is 24A. Continuous current is 3.3A. Encoder is an HP style HEDS encoder thought there is no data. It is a 250 CPR quadrature encoder with 2 channels and an INDE,  5V at 35 MA- great for use with the  G320 servo amp. Motor shaft is 1 5/8L X .305 D with a MX type timing pulley.  I remove the pulley and the shaft was turned to .250 for  5/8L. Thes motor should be great for small lathes and mills and the smaller bench top mill/drills like the sherline, taig, etc. From what I can find out these motors cost $205 each. My price is only $39 plus $5 per motor s/h


November 8, 2002

I have decided to discontinue the sale of the Mauch/ Kulaga DRO printed circuit boards and kits. Only 35 were sold this year and most newer PC's do support the ISA slot for which it was designed.

I will soon have some really nice Japan Servo  motors for the smaller machines ( ie mill drills) in a few days. They are brand new, have 100 CPR encoder (400 in quadrature) 10 A peak current rating and run at about 2700. I only have 21 of them on order so they would last long. I don't have the torque value yet but plan to test it on my mill drill this weekend.

October 5, 2002

My supplier has discontinued the IS34-022,23 and 24 motors step motors because most of his customers want the newer more expensive hybrid motors. I hate to see them go because they were a great motor and a low price. He still has the other motors listed on my web site in the products page.

I am introducing a new 3 axis stepper motor driver with case, fan power supply. You will be able to buy it piece by piece or in a kit form. I also sell this as an assembled and tested unit.

I am now proving assembled and tested 3-4 axis stepper/servo motor drivers/amps in my case with power supply and fans with all cables. Email me for pricing and availbility


September 2, 2002

The sale of the IS34-023 motors is over. I am still deciding whether or not to discontinue the 5A drivers mainly due to the unavailability of the mosfet fet driver chip at a reasonable price.

August 12, 2002

The very popular IS34-023 stepper motors are back in stock. The regular price is $130 + s/h each. As an anniversery promotion I will sell a limited quantity of these dual shaft 521 0z in motors for $120 each plus s/h. Updated the information on the 600 oz in servo motor to include the fact that these motor encoders do not require and external power supply when used with the G320/G340 .


August 1, 2002

This month Camtronics Inc. celebrates it 10th anniversery as a business dedicated to selling low cost, high quality CNC parts, software and euipment. Thanks to all that have supported Camtronics Inc.

April 25, 2002

I have ordered a batch of 545 oz in stepper motors . They should be in stock this friday.

April 20, 2002

I have sold out of the IS34-022 and IS34-023 stepper motors It will be several months before I can get more.

March 16th, 1998 - NEW 3-3-98 SINGLE AXIS DRIVERS


    * 2amp per phase Bipolar Chopper translator-driver
    * Step and Direction input.
    * Adjustable current with trim pot
    * Jumper selectable Full-Half-Wave step
    * Jumper selectable phase-Inhibit type chopping
    * Jumper selectable reset
    * All Winding Off
    * OSC. Synchronization in muti-axis configuration
    * Small size 2.5 X 3.5
    * Shunt selectable master(Osc)/ slave
    * 12VDC to 24VDC for high speed

Here it is! A NEW 2 amp chopper driver in a single axis modular form. You can set these stepper motor drivers up as single stepper motor drivers or ina multiaxis arrangement. 2.5 X 3.5. The convenient screw terminal makes it easy to connect your 4/6/8 wire stepper motors and your motor supply current. Runs
off of 12V to 28 VDC. 

The Logic voltage is provided from a convenient two pin screw terminal. Simply provide +5 and GND.

The logic header make it easy to run the stepper driver from your PC or micro controller. The polarized header has a pin for synchronisation of multiple translator drivers, signal ground, step, direction and AWO( all windings off). With a junction board this controller will easily run a small CNC machine. Now it is possible to use these controller for a X, Y Y, Z configuration for gantry type CNC machines or add a 4th axis to existing machines.

This controller uses the popular L297/L298 chip set. The chopper runs at 19KHZ. The output current is adjustable from 100 MA up to 2 Amps using the trim pot for micrometer control.   The ground clamp and flyback diodes have a Trr of 35ns.  Step rates are determined by the motor supply voltage and the inductance of the motor used. Speeds of well over 400 RPM have been attained with this little but powerful translator/driver using just 12VDC.  This controller works with most step and direction software.

February 5th, 1998 - Web Site Update.

    Added Link to Wirz Electronics web site.  We need to modify it so that it doesn't show up trapped in the Camtronics frame.

    Reconstructed the Products page from scratch in hopes of eliminating problems with viewing that page.

October 24th, 1997 - Camtronics Update.

    Since I wrote that article for Nuts and Volts nearly 3 years ago , I have come a thousand miles in developing the techniques of CCNC. Major improvements were made with the 3 axis chopper
driver kit. It increases performance dramatically. I also have designded and built a higher performace 2.5A chopper driver that uses standard low cost modules. These were placed in a case with silkscreened front and back panel. The case has a 24VDC 11 amp power supply. Best of all it has a manual and computer control mode. For running my full size milling machine it is a wonderful feature. It has an X-Y-Z selector switch and a direction switch.  A speed control pot varies the speed as needed. It is great for a three axis power feed.

Yet a flip of the Mode select switch will shift to the computer for CCNC control. I will post pictures of the controller on this web page but you may also see some of my other pictures at http://www.metalworking.com . Simply click on the check pictures box.

September 26, 1997 - Rebuilt web page using Microsoft Front Page.
