Purge and prime nozzle
I'm desperately looking for a way to start all my prints with a light purge and prime my nozzle.
I would like the front right of my bed to a place where the impression is not possible (I know my X&Y) that my nozzle purges a small amount of material then a light rubbing over a small distance to clean .
To be included in the slicer startup G-Code or as a file? Do you have an idea, or are you using something extra? Thank you
I use this for a nozzle prime and it works quite well.
;M98 P"0:/sys/PrimeNozzle.g" G90 ; Absolute positioning G1 X1 Y270 F6000 ; Move to back left corner M400 ; clear movement buffer M116 ; Wait for temps G1 Z0.3 F100 ; Move Z to prime height G91 ; Relative positioning M83 ; Relative extrusion G1 E5 F300 ; pre-prime nozzle G1 X40 E10 F300 ; Prime line G10 ; Retract G1 Y-1 X1 F10000 ; Wipe nozzle M400
Obviously you'd need to make adjustments for your printer. In my case the print head is homed to the back left corner so that's where the nozzle prime occurs at the start of the print. The amount extruded is based on a 0.6mm nozzle.
The end result is a small tab of filament that is easy to remove from the bed and leaves the nozzle very clean before the print starts.
