I have just built my first LowRider CNC. The Z0 port is no longer working. I swapped it while the Jackpot was connected to the power adapter. I assume this may have caused the issue? Can anyone confirm? And is there anything I can do besides ordering a new board?
Are you talking about the stepper connection or the endstop connection? In general, swapping things with the power on does bad things. Either way, you can probably try using a spare slot. Is everything else still working?
Yes, when i connect a stepper motor to Z0, it does not respond to commands. When I connect it to Z1 the stepper works as expected. Everything else works just fine.
The part I’m not sure about is what part this would have damaged. It could be pins on the ESP32 or the driver or something else. I’ll let someone else come along and comment since I don’t want to make a suggestion that could lead to more damage.
I believe we’ll be able to try moving the driver to the C slot and updating the config. I’m not sure if that could cause more damage if the driver is bad. It could also be a case where replacing the ESP32 could help. I’m not sure but I think there are options.
So the motor is fine, Have you tried another stepper driver in z0? Powering off before changing of course.
Yes, i tried another stepper in Z0. Unfortunately no luck. This is why I believe the board is broken.
Ok. Then next step would be remapping z0 to the spare stepper driver interface in your configuration. You need a spare esp32 to determine if the problem is with the jackpot or esp32.
To be clear, this means trying a different one of the postage-stamp sized stepper driver circuits in the Z0 socket, not just connecting a different motor to the existing driver.
In my (admittedly limited) experience, its the stepper driver that fries when changing motor connections with the system powered up. It only took me a couple times to learn that lesson. Luckily those drivers aren’t too expensive.
