Cleaning strip settings Quantity and start
Good morning dear printer fans, I need some advice from you. It's about the settings for the cleaning strip that is made before each print. Shortly before it goes down to the plate, it already pushes filament through so that it rolls on the nozzle and then prints the strip onto the plate. How can I set it so that the cleaning strip is only printed when it is on the plate?

G92 E0 ; reset extruder position
G1 E{(filament_type[0] == "FLEX" ? 4 : 2)} F2400 ; deretraction after the initial one
G0 E5 X235 Z0.2 F500 ; purge
G0 X225 E4 F500 ; purge
G0 X215 E4 F650 ; purge
G0 X205 E4 F800 ; purge
G0 X202 Z0.05 F8000 ; wipe, move close to the bed
G0 X199 Z0.2 F8000 ; wipe, move quickly away from the bed
This is the original start GCode from the C1
If he's going to start washing up, I would personally do it like this:
;
; Extrude purge line
;
G92 E0 ; reset extruder position
G1 E{(filament_type[0] == "FLEX" ? 4 : 2)} F2400 ; deretraction after the initial one
G0 X235 Z0.2 F500 ; move to bed without E5
G0 X225 E4 F500 ; purge
G0 X215 E4 F650 ; purge
G0 X205 E4 F800 ; purge
G0 X202 Z0.05 F8000 ; wipe, move close to the bed
G0 X199 Z0.2 F8000 ; wipe, move quickly away from the bed
