I have a feature request which in the pc bambu slicer would be located under the device tab, on the ios bambu handy ap it would be located under printer, and on the X1c screen would be located on the parameters screen during a print.
What I would like to see is a gcode command that the user can input during a print. This command would tell the printer to go perform a nozzle wipe at the users discretion. Once that completes, it may even be wise to do another layer on a prime tower if this can be done without crashing into the print.
Occasionally what happens to me is, I am unable to print petg for a day or so and the filament between my dryer spool holder and the nozzle is absorbing moisture. I try to keep my dryer on 24-7. I think the first 300mm of filament that runs through my machine has absorbed some moisture and tends to be sticky, right now I am printing PETG on a bambu textured PEI plate. I have had no print failures yet, but a bad enough nozzle stick incident could definitely become an issue one day.
If the user can visually identify an artifact sticking to the nozzle at the printer or through a video live feed inspection, then it would be wise to give them the option to at least wipe the nozzle from the ap and the slicer program.
