CSMIO/IP-M and PM752 Drivers

[Neale]

Very convenient that the CSMIO is 5V output! Have you also used differential wiring to the 752s? It's not shown in the 752 manual, but it just means taking the two CSMIO * and - terminals to the two corresponding terminals on the 752 for the step and directions signals. You end up with 4 wires rather than 3, and ideally twist the two wires in each pair together. You might end up doing as I did and getting one pair on one driver the wrong way round (+ and - interchanged) but it's not a big deal to fix!

I think the CD Labs website has a specific document on differential connections.

Washout just be aware that it's common for the controller's Pulse edge to be on the wrong side to what drives are set. So before continuing to use the machine just do a check of all axis.
To test write few 100 lines of short back n forward G0 moves which end at Zero IE:
G0 X5
G0 X0
Etc
Etc
G0 X5
G0 X0
If all is correct then will be back at Zero, if not then just toggle the Dir LowActive in Motor Outputs
