Mach3 with CNC Step Zero-3
« on: May 05, 2020, 09:38:35 AM »
Hello mach 3 community.
I am just trying to connect Mach3 to a CNC-STEP Zero-3 controller.
I got stuck with the charge pump. The Zero-3 is awaiting charge pump signal on pin 16. However I do do not get it running.
Is there any issue with the charge pump frequency and if yes how to modifiy it?

Anyone out there who can provide help?
Thanks Bernd

Hi,
You may have a catch-22 situation going on.
1. The controller is asserting the Estop as there is no charge pump signal
2. Mach3 is turning off the charge pump as it sees the Estop signal from the controller.

If you go into the Mach3 Config-> General tab, there is a checkbox called "chargepump on in Estop". Make sure that is ticked, as see if that solves your problem.

Cheers,

Peter
