Before I bought an Ender 3 PRO, I was using a Wanhao i3 plus, Wanhao was ejecting filament before the start of the print, I mean it is going to the left corner edge and was pushing like 5-10 mm filament to clean nozzle or release the pressure, as far as I understand, the Ender 3 doesn't do that, how can I make the Ender 3 to do same thing with G-code?
I'm asking this because the nozzle is allready heated while BLTouch is executing G29
, so the extruder motor is not moving but the filament is leaking from nozzle due to temprature, until the BLTouch finishes the G29
, it creates a long string, when the printer is starting to print, it prints a straight line between front & rear left corner, while printer printing a line that produces a string sticking to the nozzle and kills the print (most of the time that string catches the first layers).
I thought, maybe if I can force the printer to eject filament before starting to print like the Wanhao does, I could fix this problem?
I think this code does that line;
G1 X0.1 Y200.0 Z0.3 F1500.0 E15 ; Draw the first line
I would like to modify this line, but I'm relatively new to modifying G-code.
