Hi All,

I just built a camtronics stepper controller. Wiring looks good and I've set my printer port pins in Mach 2. I hooked up the X axis stepper and launched the test program "spiral.txt".

Ugh. Major anti-climax - nothing, zero, zipo, nada movement. I don't have an ocsilloscope - only a multimeter. Do I need to tie the grounds together from the PC and the controller? What's the best method to troubleshoot this puppy????

The ground that you need should come through the parallel printer port cable....send Dan a message and he'll probably give you a FAQ.

My partner-n-crime wrote to Dan and the reply was not helpful. Any chance you have the pinouts from a sucessful gecko install?

rickwinters,

Here is one link look for the servo wiring diagram:

Also for parallel port information if you want to understand how it works:

Rick, download and try turbocnc3 as i had a problem not unlike yours. No matter what i did my mill would not work.I bought deskam for dos, mach and nothing! then out of boredom i tried turbo and BAM!! It works!(well) I dont know why but the others still dont work. But the turbo does. This may be of no help but its worth a try.maybe it has a more robust pulse generator, i dont know as im a newbie. I do know it works fine even with a 25 foot cable from the lpt to the drives and i dont even have a buffer card on my cheap ass e-machine. Just the stock printer port. And everything ive read says keep the db25 cable as short as possible.let me know how it goes.

Rick, I noticed the heading on your post said "new 201" is that 201 as in gecko g201? Cuz you also stated that you just built the new camtronics controller. Which i believe is a stand alone controller.

Just call Mariss at Gecko. He'll help you until you get it working.
