<hi ive just put octoprint on my cr-10s via a pi 3b all works but now printer wont auto home via octoprint or on the printer its self any ideas whats wrong thanks in advance
no idea what to do
Logs (octoprint.log, serial.log or output on terminal tab, browser error console ...)
If your printer doesn't home correctly after issuing a G28 it is an issue with your firmware, or possibly with your limit switches on the printer. OctoPrint can only tell the printer to home, it's on the firmware to execute the command properly.
Note that OctoPrint's printer profile is only used for visualization in the GCODE viewer and when slicing from right within OctoPrint, it doesn't have any influence at all on things like regular homing and movement instructions sent via serial to your printer. It also says so in the printer profile editor.
Oh okay. I thought it might won't send any more arrow key movements. Now I know better.
Was a bad idea anyways - without homeing it wouldn't know where to stop
That's something people have asked about but frankly something I do not want to implement. It's the job of the firmware to define the boundaries of the print volume, and messing around with that from a host IMHO just is asking for trouble
