When running, my BLTouch probe stays lit red. Is that normal. It seems to work fine, but it strikes me as strange that when printing, it stays lit red.
When the auto-level process is taking place, filament keeps dropping out of the head. Not a lot, but a few cm here and there. The bad thing is, once printing started, this messy gob decided to fall off into the fresh, hot skirt material.
What is the secret to having no filament extruded while the printer is levelling, so that when printing starts, the head is clean?
