Hey guys, setting up my Lowrider 3 with a SKR 1.4 Turbo / TMC2209’s. Using the Marlin 2.1.1 firmware found on the V1 MarlinBuilder github, except I am compiling it myself.
I have the X and Y axis working and homing correctly.
Z axis is working correctly, moves up and down when you use “move axis” fine. However when homing it is only turning the right side (xmax end, connected to X1 driver) stepper motor. The left stepper (at xmin end, connected to E1 driver) doesn’t turn but it is active (I cant turn it by hand while its trying to home).
Endstops are all working fine including the probe input, all report “open” with M119 and all report “TRIGGERED” when I activate them with my finger.
I have swapped drivers, swapped stepper connectors around (so the other end moves instead), and found its definitely a firmware issues since “move axis” works fine.
I cant see what it could be. Z2_DRIVER_TYPE is defined. Z_MULTI_ENDSTOPS is defined and appears working with M119. Unless someone has any ideas my next thing will be moving all the V1 MarlinBuilder changes to a fresh copy of Marlin 2.1.2 and seeing what happens.
Thanks in advance
