Nozzle Wipe

Hi,

How do you specify where you want the nozzle wipe to occur at the beginning of a print?

Over the years, I have started to damage the PEi sheet around the top edge from removing the bits of excess plastic.

I was hoping to shift the nozzle wipe to a fresh area.

Is there some GCode in Slicer, or is it baked into the firmware?

Any help much appreciated.

Thanks.

Re: Nozzle Wipe

The intro line (or nozzle wipe as you've called it) is part of the 'Start G-code' in your slicer setup.

G1 Y-3.0 F1000.0 ; go outside print area
G92 E0.0
G1 X60.0 E9.0 F1000.0 ; intro line
G1 X100.0 E12.5 F1000.0 ; intro line
G92 E0.0

Thanks.

That's where I thought it would be but this is all that is in my 'Start G-Code' in slicer.

M115 U3.1.0 ; tell printer latest fw version
M83 ; extruder relative mode
M204 S[machine_max_acceleration_extruding] T[machine_max_acceleration_retracting] ; MK2 firmware only supports the old M204 format
M104 S[first_layer_temperature] ; set extruder temp
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
M109 S[first_layer_temperature] ; wait for extruder temp
G28 W ; home all without mesh bed level
G80 ; mesh bed leveling

The lines you posted are what I see in Slic3r when I bring up the settings. The lines I posted are present, but not visible until I scroll the text box containing the 'Start G-Code'.

Re: Nozzle Wipe

Hi Guys,

I put a piece of 10mm capton tape across the prime line area on my PEI sticker, and it both covers the area where a piece of pei ripped out, and makes the prime line easier to remove after a print!

Thanks guys.

Found the G-Code now. Amazing what you can do with the scroll bar!! 😳

The tape idea is also great. I may try that too.

Thanks all.
