E0 Motor4 non functional #143

Open HillDweller117 opened 1 year ago

HillDweller117 commented 1 year ago

I’m running the latest marlin with an octopus v1.1. I have two z steppers on motors 2 and 3 and e0 is set to 4. Everything works perfectly except that I cannot get e0 to move, I have tried setting DISABLE_INACTIVE_E to false and swapping the e0/e1 pins but neither have fixed it. Motor and wires are both functional so not sure if it’s a board hardware issue or if I’m missing something. I’m also aware there are two motor 2s in tandem and have skipped motor2_2

I had trouble with the E0 as well and spent much time learning to use marlin autobuild and building from the 2.1.x branch instead of bugfix branch that is provided by BTT and finally got it working, however my issue appeared to be a simple mistake of using motor 3 port not knowing the configs i started with used 2 Z axis motors (plus one parallel Z in hardware) and simply skipping motor 3 might have been the solution, I am now second guessing that after reading this. Perhaps changing branch may help you like me. To be thorough I would suggest double checking your configured UART or SPI pins and jumpers for your drivers.
