Avoiding Hairballs with PETG?

Anyone who has used PETG knows how stringy it is. I've been using it a lot, and the prints are coming out fine, but I just discovered a minor issue. My ending script retracts 15mm, shuts off the extruder & bed, lowers the print bed a ways, and then shuts off the motors & bed fan. Now that my M2E is ...

Re: nema17 dampers

They are presumably fairly standard, so there is always the option of finding a higher temperature rated stepper. At least now we have the specs.

Re: nema17 dampers

Yes, but measured where? Is that case temperature, winding temperature, or what ??? The top of the operating ambient temperature range is only ~ 40C, which makes using them in a 50C heated enclosure a bit worrisome....

Re: nema17 dampers

I'm not sure how accurate it is, but I have an IR thermometer, and it claims both my X & Y steppers are only running about 15C above ambient. That's fully clamped to the associated metal bits. I couldn't find any obvious visible markings to get a model/part number on the steppers, so I have no idea ...

Re: nema17 dampers

I've been considering doing this upgrade. The one downside seems to be that the dampers significantly reduce the heatsinking the motors see. There are 40 mm square heatsinks you can stick on with thermal tape or epoxy. Has anyone noticed that their steppers are getting extra toasty? Anyone using hea...

Re: S3d Default profile

Why doesn't S3D ship with a default profile for the MakerGear that prints well? Every new owner has to come here and ask about layer shifting and then adjust their speeds. Every new user has to wonder why their support material breaks off the bed and then learns to add pads. Every new user gets lot...

Re: M2 nightmare with soft filiment

I've modified the factory drive model to give the added clearance required for the grooved sleeved bearing, and printed one up in PETG. The sleeve & bearing combo now spins freely until you really crank on the tension screw, far more than normal. The next time I change filament, I'll swap this drive...

Re: Anyone Try Polymaker PC-Max?

That second comment was from an Amazon reviewer, not me. I have NOT opened mine. I'm still working on finishing my enclosure in the hopes that will help with whatever flavor of PC I end up using. One reviewer of the Polymaker PC-Max stuff who really liked it has a heated enclosure. It will be some t...

Re: Anyone Try Polymaker PC-Max?

Of all the users on the forum, I trust that if Zemlin got a bad roll, he would have figured that out & done something about it. I may still experiment with it later, but I don't have time to screw around with suspect filament at the moment. An Amazon reviewer had strength issues with the black ePC a...
