I loaded a 3D printer software and everything was working fine, then I did an update on the 3D printer software and now my third carriage to home moves away from the stop switch during home. I tried clicking the stop switch manually as the third carriage was to home but nothing happened. I read the software and the gantry height was all 9's when it should have been 315mm. I have Reprap software now but it does not have a gantry height entry and my Kossel delta-mini user interface seems to have no errors but I am not familiar with the printer's pre-programmed information. Do I need a replacement mother-board? Is my mother-board ruined? Is there a way to get the third carriage to home correctly using the printer user interface and changing any of the input data for the axes? Will unplugging the stepper motor to that axis and manually forcing that carriage to home help? Thank you for responding to my dilemma. I am not too technical with 3D printers so please use plain language.
