I have printed Abs many times with this printer, but now it is really giving me fits. I just used PLA to do a print and everything was working flawlessly. I need to do a project in ABS so I ran the e-sun cleaning material through the nozzle at PLA temperature and after it is clear color, I insert th...

Ok great.

Thank you for the instructions. I just tried it today and it seemed to purge out the previous filament just fine.

Once again Jimc you nailed it! I turned down the xy default speed from 18000 down to 9400 and I had no issues at all. This is a replica of the DDG 1000 I drew up on Geomagic design. I still need to attach the back with 4-40 machine screws and print the bottom half in red. To be continued.... Thanks ...

I have noticed on my larger prints when the print bed moves fast from front to back, (long distance) from one corner to the other it sounds like the print head or print bed hits something. Then the object I am printing gets messed up. After I hear this noise the printed object has a shifted layer ef...

I am going to double check filament dia and tension screw pressure tomorrow.
Thanks again.......

It sounds like the fan blades just nicking the fan enclosure. (fast ticking noise, but it only does it ...
