Need help tuning starting script

G28 ; home all axes
G1 Z0.5 F1200 ; lift
G1 X280 Y5 Z2 F5000 ; move to wait position in right corner
G1 Z0.4 ; position nozzle
G1 E25 F300 ; purge nozzle & create anchor
M400 ; wait for purge to complete
G1 X200 F1200 ; slow wipe
G1 Z0.5 F1200 ; lift

I need help with the line “G1 X200 F1200 ; slow wipe”.

I would like this to be a significantly faster wipe and move further. To make it move more to the left do I increase or decrease the X value? As for speed I have no clue. Any input is greatly appreciated.

Looks like its going from x280 to x200, at a federate of 1200 (possibly mm per minute) . increasing f1200 should make it faster. Changing x200 to a different number will result in a different position, higher will end up closer to the 280 starting spot, lower will be further away. Above 280 would be on the other side of the start point, and probably off the bed entirely.

Excellent, I think I’ll try the following and report back.

G1 X120 F2000 ; quick wipe

So far so good. I think I’ll turn on the fan and turn it off after the wipe to keep it cleaner.

G28 ; home all axes
G1 Z0.5 F1200 ; lift
M106 ; turn fan on
G1 X280 Y5 Z2 F5000 ; move to wait position in right corner
G1 Z0.4 ; position nozzle
G1 E25 F300 ; purge nozzle
M400 ; wait for purge to complete
G1 X120 F2400 ; quick wipe
M106 S0 ; turn fan off
G1 Z0.5 F1200 ; lift

This is working great! Now I can start off prints with a clean nozzle, even with really stringy filaments like PETg.
