I am trying to get my G540 drive to work with the smooth stepper. The issue that i have is when i start the mach and the smooth stepper the e stop input won't clear due to the charge pump not firing up because mach won't start the smooth stepper due to the estop.

I am using the error line on the G540 as the E-stop input at the moment.

I know everything is working as i can disable the E stop and no problems. Effectively i need to delay or over ride the estop untill the smooth stepper generates the charge pump signal.

You need an enable button as a temporary override for start-up. I use a simple PTM momentary switch. Sequence is Mach on, controller power on, press enable and clear Estop condition in Mach. Then you are rolling.

Posting on the Mach Forum there is a setting on the general page that allows the generation of the charge pump signal while the e stop is engaged. I always thought there would be a software solution. Many thanks for the help.
