when during printing i change the extruder multiplier in the Machine control panel.
from 100% to 94% then after some time the extruder stops (no plastic)
the preset for extrusion multiplier was 130%.
when i set the Tool change retraction distance" to 0.00
i noticed that the Tool change retraction -SPEED- can not set to 0.00
maybe this is a hint for the programmer to solve the retraction too long problem
thanks for answer
yes i know about the spooler, i tried many things and sometimes the printer starts working
but then everytime something goes wrong.
maybe your friend can help
thanks
