Trying to Understand Start G code
Looking at start GCode for the MK3S+ I see the following two lines one right after the other:
G1 X60 E9 F1000 I understand this to mean go to X60, extrude 9mm of filament to draw a line
G1 X100 E12.5 F1000 Is this drawing another line? If so, why 2 lines?
Confused Nimrod. thanks for your help. George
RE: Trying to Understand Start G code
That means:
1. line of gcode: go from the actual position in x to position 60 (mm) with feedrate 1000 mm/min and doing so extrude 9 mm of filament (in parallel - during same time)
2. line of gcode: go from this position in x to position 100 (mm) with feedrate 1000 mm/min and doing so extrude 12.5 mm of filament (in parallel - during same Time) - so the filament flow is now a little increased.
To get familiar with gcode have a look to: https://www.reprap.org/wiki/G-code

Makes sense. Thanks very much!
RE: Trying to Understand Start G code
bobstro did a really nice breakdown on the starting G-code here: https://projects.ttlexceeded.com/3dprinting_prusaslicer_gcode.html
That is also were you can find a modified start code that quite a few people use. It includes a warm up routine for the PINDA for those chilly mornings and a slightly different/longer purge line.
