G540 - 4 motor connection problem

[dachopper]

Ignoring Voltage/Power supply discussions, what is the actual fault you are seeing?

Do the motors stop/stall, the drives fault out...?

It's reading the CNC code, then the Gecko unit fault light somes on and that disabled everything

Is seems to happen a lot more - the higher the voltage I set on the switch mode power supply, I thought I had it working on the 42Volt setting, which is the lowest possible, but it stopped 3-4 times around the same area in the workpiece today

I tried to re-do it at slow speed, with slower accelerations and it still stopped - it's not jamming, it's running at about 30% of the jamming speed, it's being turned off because Gecko is giving a fault for some reason. the CNC program is still happily running in the background sending commands out

I switched over to another lower 30 Volt switched power supply that is also half the power ( 300 Watt ) , and I've had to slow down the motors and accelerations even more, as it's now almost half the efficient voltage I need. It seems to be getting through the job, although I had a few missed steps due to high loading at times during the cut sequence - so I've reduced the speed/accel even more

I don't know if it's a power problem, or a geckodrive current draw issue, or voltage issue - mystified
