UM3 Extended printing with abrasive materials

[Jls667 0]

This is really a two part question.

 

1. Does it make sense to give my UM3 Extended printer abrasive material capability?

 

2. Will Cura recognize the new PrintCore CC with my UM3 Extended printer? I already have a Bondtech extruder.

 

Thank you.

I dont have the CC core but if printer doesnt like it you could re-configure it to look like a standard AA core.

Scroll down a bit in this thread:

Thanks. That does not seem hard.

Its certainly cheaper than buying a S3/S5 just for abrasive capability so it makes sense in that regard. We have the Bondtech feeders and CC core in our plain UM3. Its not happy about it but it does work, you just have to click the manual override for every print. Haven't tried tricking the printer into thinking its a different core but seems like a better solution long term.

Great to know that overriding is an option. What abrasive materials do you print?

I have both my UM3 and UM3X set up for abrasives.  I run mostly nylon/CF but also nylon/glass.  Both have Bondtech feeders and 3dSolex Hardcores with everlast nozzles.  I've been really happy running with these.  I have recoded them to look like AA cores of the appropriate nozzle sizes and haven't had any issues.

Since the printcore cc is an unusual size of .6, how do you modify Cura to allow for this?

Just set the line width in Cura to 0.6 or to 7/8 of 0.6 if you want to follow the UM line width style.

Thank you. I’m glad it is so simple.
