Welcome to the SeeMeCNC Community

I've tried inverting the axis, but it doesn't appear that Arduino is uploading to RAMBo controller. Found this in the Zendesk about the home function - machine is homing properly and I'm performing a new Z calibration. https://seemecnc.zendesk.com/hc/en-us/articles/206115260?input_string=home ...

I've attempted to re-home, but now when I do a G28 the machine moves downwards 10 mm or so instead of moving up to the end-steps. This printer has printed correctly before. This is my Arduino Configuration.h file. /* Printer Model List as used throughout this firmware Orion = 1 Rostock Max V2 = 2 ...

My printer was working correctly as of January, but now it's not performing the full Home sequence (only moves up a couple of inches) or performing the G0 7200 F300 calibration at all. The endstop test works.
