Shamoon78 commented 4 years ago

GTR board with 2 tmc 2209 dirvers on z with diag pin removed on both, z2 stepper is connected to E1, endstops both working normally if i triggered by hand , z axis working normally with both steeper working when use move axis on tft , BUT the issue is when use home z only the steeper connected to z turn the other one that is connected to e1 is not working. I activate the dual z (z number 2 ), and add the driver typed tmc2209 to e1, and configured bothe stepper current the same in marlin using the demo that come with BTT GTR files . Any help will be appreciated with my great thanks to you guys who spend day and night try to help us .

I SOLVED THE ISSUE, I noticed that E0 (xmax) light is not on , and nothing happen when triggering the xmax endstop, so was the E0 diver pin the only one i forget to remove to activate the end stop, even E0 driver is driving the extruder motor but still need to remove the diag pin to avtivate the mechanical xmax endstop.
