Nozzle wipe during two material print
-
I have a lot of material oozing while I change extruders (a 100 mm string out of one particular extruder with a 0.4 mm nozzle). The quantity is well past the ability of just wiping the mess on the prime tower. Has anyone implemented any nozzle wiping action on nozzle change? Would you mind posting a picture of your setup?
My printer is a Creality CR10 kind of printer but any setup could help me get an idea of what to do. -

Truly mind boggling what you have achieved there!
Question: my nozzle only moves in the X direction so I can't do the fancy sideways slide thing that you have programmed nor distribute the wear over the strip. I can mount the silicone strip at an angle so that helps to better wipe things but it will always hit the same spot and I will probably have to heat up the second nozzle even when not used to prevent any remnants on it from destroying the wipe strip. All do-able but what kind of a life expectancy could I see out of the wiper since the same spot is used over and over?
Any thoughts on that ? -
I think I have my answer - I will mount the silicone strip on some kind of a motorized shuttle mechanism that slides the strip back and forth which will distribute the point where the nozzle contacts the strip. More thinking to do ... but I got a good start.
Thanks !
