Still having troubles drawing tonight.
What I’m trying to do is set zero at the bottom left of a piece of paper. I connect in Repetier, use the arrows to move the point of the pen to the bottom left of the paper and touch the surface, then I send the G Code command G92 X0 Y0 Z0 E0 and also @isathome. Then I raise the Z by 10 so that the ink isn’t soaking into the paper. Then I run the program. It draws in the air. If I do not raise the pen it will draw on the paper.
Also, even though I can’t find any settings that change home position, when it returns it is always slightly in a different position than where it started.
