Attach a G-Code file that you use on the machine and I will show you how to edit it.

The other option is to open the g-code as a text document and use the edit - replace utility and replace the Y, U , and V
with a X

The TIP122 has a built in diode - reverse biased for the back EMF

Is there any specific reason why you are using the DSPMC instead of the parallel port break out board?

In ports and pins, set your x axis, y axis and a axis output the same and set the tuning as the same, as long as you do not move the axes at the same time, it should work.
eg: step pin # 7
     dir pin # 6

VB and the development of wizards / Re: How to run a script after each Gcode in single step mode

« on: June 21, 2010, 11:23:41 AM »

Punching machines run in single step mode after an M-Code ie: M25. After every line of code, the pate needs to be punched and then continue until another M-code ie: M22, which cancels punching. The macropump will have to look at the M25(set) and M22 (reset) conditions.

On the safety side, there is a light barrier which is connected in the emergency stop circuit around the punching area.

"My question is; what does the drive do when it is re-enabled after a disable if the axis was moved during the disable?"

A: It will start from the wrong position

"If the axis was moved, does the drive consider the new position to be OK, or does it try to immediately return the axis to the pre-disable position?"

A: It will assume that the position on the axis DRO is correct.

Mach3 runs open loop with no encoder feedback for positioning, so if you kill the power to the servos while Mach is sending out the pulse & direction signal, Mach will not know the exact position and will have to be recalibrated.

If you use an encoder break out board to check the position in Mach, the you can transfer the encoder position DRO data to the axis position DRO.

You should be able to do the homing routine in Mach3
