Thanks Dave and Hood

I am using the 282 oz in motors. http://www.kelinginc.net/KL23H276-30-8B.pdf

A+ = Blue & Yellow
A- = Green & Red
B+ = Brown & Orange
B- =  Black & White

Is this correct?

Thanks

Ok I have checked everything and double checked.

Question in windows under device manager then LPT1 port , Port Settings "Try not to use as an interrupt" is checked. All other dialog boxes are NOT checked. Is this correct?

Thanks

I would like to thank everyone for taking the time to help with this problem.

I am using LM7805 to derive my 5volt supply however it is engaged at the same time as the stepper drive power. Maybe I should have two switches? My power supply is 35VDC 10amp with 27000Uf 50WVDC Cap. It sounds like I need to switch Bob after Mach is online then engage stepper drives. I didn't know voltage where reversed on C10 I changed the jumper to 1&2 ouput . It was by default on 2&3 input. Maybe I should have left the jumper alone. I am using KL-4030 drives from Keling Tech. I only have step and dir. wires coming off of the Bob to the drives. I have enab. and +5 volts tied together and then Grnd on Grnd. I have +5 Volts to the drives logic coming directly from the LM7805 not thru the bob at all. Could this be the problem or should I have left the jumper in default setting. jumper 2 was left common ground but I didn't use it. One thing i did notice is that on power up of Mach the Bob led was on then went off when I flipped the switch to engage the steppers. By that time it was to late smoked bob and fried computer. This is a real puzzle because I have tried other drives and other Bobs and similar problem but instead of the bob and computer being smoked the unipolar drives burned up. Like as stated I'm a newbie and it shows. Really disappointed and running out of money to keep building computers.

Thanks

I'm using ECS motherboard with AMD AM-2 socket 1.9 ghz Sempron CPU 1Gig of DDR2 memory and windows XP SP2 along with C10 breakout board. Everything was fine when I engaged the drives the motors locked and led on the breakout board and drives where on. I connect the paraell port to computer turn computer on then Mach-3 then engage stepper drives and pop goes the breakout board (smoke) and screen flashes and then my computer fried. This is my second computer. Need help. I checked bios prior LPT1 assigned 378 and set to normal. I ran Mach driver test also. My cable is made by Belkin. Mach 3 set up correctly using sherline 1/2 pulse mode for my stepper drives as required. I really need help.

Thanks

This is a sub routine for making a work holding jig grid pattern 5" by 6" with 1" centers using 3/16 drill . You can easly modify this code to whatever size you need with copy and paste in MS note pad. Hope this helps someone out.
