Adjusting the current seems to have done the trick! I haven't had time to run a long print since I want to be near the printer in case it jams, but from the 2-3 hour print I did, the motors were cooler than before. The test strip of PLA didn't melt like before (only got a tiny bit soft). Now I just ...

It might fix the problem, but I think its more masking an underlying problem that I would like to try and figure out. Edit: The print that was going with the cooler fan just failed. The stepper was in fact kicking back. It seems like the stepped is running hot, which normally is fine, but then it ...

Yes, definitely PLA - blue flame (and smells good when it prints)! Anyways - I think the solution might be to add a fan pointing to the stepper. I have a decent sized desk fan blowing on the extruder motor right now and it is staying very cool. I'm going to try to get a smaller fan that I can mount ...

That's not too awfully bad, pla has a glass transition.temp of about 138'F, and abs has a glass transition temp of about 220'F. By the look of it I think your stepper is running maybe 120'F. That's not overly hot. But if your extruder is plugging, the stepper could heat up more. Is there any marks ...

Try this as an indicator. Cut a length of pla and abs about 2" then lay both of them on top of the stepper near the driver with a bit of length sticking out past the motor. Then print something. This should give an indication of how hot the extruder stepper is getting. If they droop over, something ...

Guanu - it is a kysan motor. Unfortunately I don't have a temp sensor so I don't know exactly how hot the motor is. It is definitely hotter than the steppers that drive the belts. I'm going to try printing at 220-230C tonight to see if that helps. Everything I've read online said that was too hot ...

That picture is really interesting. My PLA doesn't smush up like that, it looks like how ninja flex would smash up. My guess is that the extruder motor is getting really hot and is softening the PLA meaning it can't push itself anymore. Yes, the stepper does get very hot. This was something I ...

One roll is from Sainsmart and the other is from FilamentDirect.com. Both have printed OK on other printers. I checked both diameters and they are good, both around 1.73-1.75mm. I haven't tried drying it out. How would I do this? I should also mention that they print fine for about an hour or so ...

I've had my Rostock Max V2 for about 2 weeks. ABS prints ok, but any time I try to do PLA, my EZStruder jams with PLA. II've tried to play with the settings by using temperature 175/180/190/200/210°C, with and without retraction, and I've increased/decreased printing speed. Every single time I end ...
