Hi
Im having trouble with my x axis.It has 2 stepper motors and 2 ball screws so 1 motor is a slave.What is happening is one of the motors will completly
stop when I am moving x axis.Then if i let off of the jog button and then jog again it will start working again but only briefly then it screws up again.I have tried unpluging the motor plugs and swapping the motors and the problem goes to the other motor.So it looks like the motors are good and also the cable to the motor is good.They are both using the same power supply so that isnt the problem.I have swapped out the axis drives and that didnt help.I have swapped to different pins coming out of the c10 board and changed to the coresponding motor number in config and that didnt help.Today I moved the power supplys and any other components that were running off of a.c. out of the cabinet and 2 or 3 ft away from the d.c. side to see if I had a noise problem but that didnt help.
For the drivers Im using KL-4030 from automation technologies and 425 oz stepper motors.The breakout board is the c10 that came with the kit.
The motion controler is pmdx-411.
The Mach 4 version is 2803 the pmdx is 33.159 and firmware 42.137.
The computer Im using is a Dell optiplex 755.Intel core duo 3.0 ghz 8 gb of ram 64 bit windows 7 pro sp1 and a nvidia graphics card.
In Mach config I dont have anything setup in the input or outputs other than the e-stop button and it works fine.
I dont know what else to check or what to do and I was hoping you guys could help Me solve this before I pull the rest of my hair out.
Thanks

On the Mach config for the motors I have it at 16260.1626 counts per, 20 on velocity, .31 on acceleration
