?Script for prevent the wasting material

[chacaman 0]

Hi, guys, thans for time and help, How can I avoid wasting material when the printer is preparing to print? Is there a way to retract the filament as the printer prepares and then re-enter it when it starts? so we avoid dirtying the nose and wasting material

 

thanks

Hi  Chacaman,

 

If you really want to do this you could add custom 'end G-Code' to in the printer settings that retracts the filament x-amount after every print. This will cause the purge extrude no material. You can find the 'end G-Code' settings under Settings>Printer>Machine Settings. You will need to add something like M83 followed by G1 E-10 or something.

 

I have to say that I would not recommend doing this. Since the purging process is actually designed to make sure the flow of material is stable before starting the actual print. In addition to this the purging will prevent the material from 'curling' up and sticking to the nozzle when the plastic starts coming. The amount of plastic lost during purging is very small so I wouldn't worry about it too much.
