Yes, I tried just two processes also and checked "Continuous printing - Layer by layer". Going into Prepare to Print! and viewing the tool path S3D does not cycle through the parts correctly if you look at enough layers. It will not continuously cycle correctly like the following illustration if Part1 and Part2 are both part of the same part (meaning a Dual Extrusion part):
My S3D settings are extruding the correct amount of filament w/out Extra Restart Distance so giving that a positive value would cause too much filament to be extruded. I'm trying to speed up the purging process of purging the old color out of the Cyclops hot end before starting the new color so I'm extruding at maximum speed off the side of the bed and then slowing down for the Ooze shield to reduce pressure in the bowden tube.KC_703 wrote:Have you tried the "Extra Restart Distance" parameter in the extruder tab? Specifying a value will prime the tool before printing the ooze shield... possibly negating the need your custom script.
The other thing to try is to also enable the "Prime Pillar". The pillar will print before the ooze shield after the tool change. Set the pillar size to whatever you need to even out your bowden pressure.
These feature work on my dual extrusion printer. I can't validate for the diamond or more three or more tools... which seems to be what the picture is showing above.
Regardless, try the built in functions to prime the tool before printing... I think they serve the same function as the custom script. Use the simulation function in the print preview to validate.
