OK I'm Ashamed.
I am one of those that started a machine and never finished it. I started it over three years ago, here’s the link to the build thread http://www.cnczone.com/forums/showthread.php?t=2695. I’m biting the bullet and finally getting back into it.
Forgot all I know about the electronics, which was my weak link to start with. And the reason I stopped. My CNC is mechanically complete, but I have been procrastinating because of my fear of the electrical system, and putting something in backwards and blowing the whole thig up.
Here is my electrical configuration: (Antiques now)
Controllers (3) XS-3525/8S-1 from Xylotex …………………………………………$120
Stepper Motors 116 oz/in from Xylotex ……………………………………………... $60
A friend of mine gave me a 25.6 VDC 8A power supply that should work with my system. The PS is made up of a transformer, 4 diodes 2 capacitors and 1 resistor, he says it is unregulated. It’s a heavyweight at 19.5 lbs.
My current problem is that I need a parallel interface, between the PC and stepper control boards. Is an optically isolated one the way to go or just a universal one? Could someone recommend some of each? Also could this interface be used with Servos?
Thanks :rainfro:
