Can't figure out how to do variable length purges
So with Slic3R or the Mosaic Palette slicers, we can have variable length purges based on color strength. It takes less purge to go from white to black, but more purge to go from black to white. I can't for the life of me figure out how to do this with the static purge lengths that the retractable purge mechanism seems to dictate. Heck, I can't even figure out how to get started with either of these two slicers. I presume that I need to configure the slicer to do "side" purges- but how do I actually determine how MUCH to purge? How to I connect how much Slic3R or Mosaic are purging, and then transfer that value to a tool change script?
SimplyColor3D Cannot do variable length purges.
The Retractable Purge Mechanism must have 40mm purges. So it's possible to do variable length purges as long as the total purge length is evenly divisible by 40.
To get started there are 2 pinned posts in the forum, one for Slic3r and one for SimplyColor3D. There are also notes in the getting started google doc :
The amount to purge is a trail and error thing. It will depend on the material (type, color) and temp. It's probably going to be between 80 and 160 mm of filament. Slic3r PE starts with 140mm & SimplyColor3D just gives the size of the prime pillar so you would need to look into the gcode file for the extrusion length but it will still need to be between 80 and 160mm.
Yes, I have read the startup notes- and it is now clear to me the trial and error aspect of this when using other slicers. I was just wondering if there was a more concise way to set up the scripts to control this. I'll keep working with it. It also occurs to me that perhaps a way to post-process with some scripts might be another consideration (something like P2PP comes to mind).
Well not to let the 'cat out of the bag' too early....but P2PP is getting an upgrade that will do exactly that. No eta on it yet though....
