I currently have a polar 3d 2.5 printer that has a broken Z-stop mosfet and supposedly polar3d has stopped support for it as of september 20th, 2018. I've tried the instructions regarding the bad z mosfet but nothing happens when plugging the usb with the hex file (no lights,etc). In addition, during a firmware update over my local ip I had a power outage which left a lot of functionalities broken (why i now use octopi).
What is the problem?
Aside from the backstory... I'm trying to get around my mishap by printing without a z endstop but whenever i upload gcode through octopi it still homes the z axis when starting.
What did you do already to try and solve it?
I've tried changing some of the gcode to only home to the x and y axis (which are still functioning) with G28 X0 Y0. Then I manually set the Z axis to zero with G92 Z0 when the extruder is comfortably touching a piece of paper at the base plate.
Attached below is the gcode I used. Sorry I'm new to all this
