HI,
I am setting up Mach 3 with a Geckodrive G540.
When I turn the charge pump switch off on the front panel of the G540, I have normal stepper motor control. Good so far.
When the charge pump switch is on, and Mach 3 is not running, the G540 fault light come on, so far so good.
I have port 1 pin 16 configured to output the charge pump signal in Mach 3. The LPT1 port is in EPP.
If I set "charge pump on in estop" true in the config, I can press reset in Mach 3 and the G540 goes ready. I suspect this tells me that the electrical connectivity for pin 16 is fine. Pressing RESET does not fault the g540, as I would expect with the charge pump signal always active. the hardware estop switch does fault the g540 normally though, and I see estop toggle on the diagnostics screen as i would expect.
If "charge pump on in estop" is set to false, when I send a reset, the g540 flashes green and immediately goes back to red (fault), I suspect due to the estop signal coming from the g540 not toggeling to estop false quickly enough, perhaps? A race condition of sorts, I think.....
When the reset is pushed and I get a green flash on the g540, I also see a very fast flash on the diagnostics screen "emergency" LED. I also get the "fix inputs" box pops up at various time in this process when it loses track of the estop state.
Running drivertest gives what the docs say is normal results, a nice straight line with few or no glitches.
I tried setting the charge pump to active low with no real change apparent, either way.
What am I missing here? I desire that the g540 fault when RESET is pressed, or is it working the way it is supposed to?
Thanks!
