How Print with PVA Support Material without Mulitmaterial Upgrade???  

RE: How Print with PVA Support Material without Mulitmaterial Upgrade???

Hi,

In theory you can slice it with MMU2 settings. Replace all filament change instructions from gcode with a simple M600 command. Have fun by changing the filament every minute for couple hours (depends on the object you want to print).

Or you can just buy the MMU2S upgrade.

You don't even need to hand edit the g-code to insert the M600 codes, put the M600 into the custom g-code for tool change. You probably don't want the MMU2 g-code in there with all the extraction distances, ramming, etc. Just specify multiple extruders and dedicate one of the extruders/tools to support interface. Check out the acting as my own mmu thread in this forum. Yes, you will need to babysit the print to do all the filament changes by hand...

if you do try that...plan on plenty of time for babysitting,  you'll get a hang of changing the filament without blobs.  temps might be an issue  BUT  you can change temps after the filament is changed. old school style
