Re: Best bed and quality spool for ABS?

The glass bed is significantly cooler in the corners than in the middle. An aluminum bed really evens out the temps which gives better adhesion toward the edges. I've posted thermal images in this forum before to demonstrate this. FWIW, I occasionally print ABS in my air conditioned room with nearby...

Re: Advice for cleaning V4 extruder

I wish I had taken some "Before" pics. Before the torch and before the ultrasonic. This is the after. The picture makes it look very dark since I'm basically taking a picture at the bottom of a cave and the light is mostly illuminating the outside of the nozzle. Trust me , it looks 100x better throu...

Re: Advice for cleaning V4 extruder

WIll do. I just torched my badly PETG-clogged nozzle. Heated it until dull orange and then just let it sit on the fire brick for 5mins until it was cool enough to handle. I have a nice microscope so I examined the bore after the torching. There was a pretty clear hole thru, probably 75% clear and wh...

Re: Advice for cleaning V4 extruder

Airscapes, I just swapped from ABS to PETG and I ran 200mm of the cleaning filament at 100mm/min instead of the default rate of 300mm/min that I usually use. It did seem to take more before it ran clear, I had to run 200mm and usually 100mm is sufficient, so maybe it does capture more crud at the lo...

Re: Advice for cleaning V4 extruder

Airscapes, I have the esun cleaning filament, but I've never really noticed that it does anything. When I flush it through, it will carry traces of the previous color, but it never seems to take out any black specks. I have never tried extruding it slowly, what speed do you use? I'll give it a shot....

Re: Advice for cleaning V4 extruder

Resurrecting another very old thread. I haven't had a clog in a long time, but I just switched to PETG from PLA and got a bad clog on the second day of printing (my clogs always happen after changing to PETG). I swapped to a new nozzle, but now that I have two clogged ones in my pile, I'm going to c...

Re: M2: The indestructible

The MakerGear is the best 3D printer that I've ever used and I used to have access to much more expensive machines such as the Fortus at work.

Re: Bed heat not working after replacing thermister wire

Ok, if a thermistor reading of zero disables bed-heat as stated above, then it's only for that session. I just pulled my rambo cover and hooked up a meter, turned on bed-heat, got 24v. jumped between the rambo terminal and the bed connector and the bed heat works. That wire must have failed as-well ...

Bed heat not working after replacing thermister wire

The thermister wire for my bed heat died a while ago (1+ year). Since I was busy, I just slapped some glue stick on the bed and kept printing with heat off, the bed temp readout used to flip between ambient and 0 while printing which helped me confirm that it stayed broken. Two weeks ago, I finally ...
