Re: Nozzle wont go over ~210°C

Thanks all for your suggestions. As it turned out, it was a broken thermistor wire that occasionally dropped out. After swapping the thermistor and then carefully checking the wires, i noticed a kink. So i plugged it back in and wiggling that kink made temperatures jump. Looks like i am back printin...

Re: Bed Screw not fiting with their hole

Eduard,

sounds kinda like the classic "wrong side up during assembly" problem. Is that possible?

If you have the black frame reversed at step 13 here: http://manual.prusa3d.com/Guide/2.+Y-ax ... /298#s5072 you'll end up with the holes not aligning to the threads in the heat bed..

Nozzle wont go over ~210°C

Hi there, I have a new problem with my MK2. Starting a few days ago, i seem to be unable to maintain a nozzle temperature higher than approximately 210°C while printing. During preheat, so while printer is standing idle there's no problem. Reported temperature is correct, i verified it with a therma...

Re: Dyze Filament Sentinel help

Unfortunately, I am on a different PIN plus I need Z-Height of 220mm otherwise i wont get past calibration (i ditched the Prusa frame and went Haribo). I'd have to recompile from your source and i don't think i'll get around to it this week :-(

Re: Filament Stuck

I don't think they ship that ring together with the tube. I have no clue why they're showing these plastic pressfits there, they're not mentioned in the description. Might want to check with e3d. I think you'd need this: http://e3d-online.com/E3D-v6/Spares/Embedded-Bowden-Couplings-For-Metal-1.75mm-...

Re: Print bed frame wont align with heatbed standoffs

Classic cause for "2 middle holes don't fit" is: accidental reversal of the black y-carriage during step 15 of the build manual: http://manual.prusa3d.com/Guide/2.+Y-axis+assembly/298.

These holes are not dead center, so orientation matters.

Re: Filament Stuck

That black ring seen around the PTFE tube, usually you can press down on it to unlock the tube. After that, you might be able to pull out the tube and the blockage in there. Since you're using PLA, you can try to heat everything up with a blow dryer or some such, the PLA should soften long before th...

Re: MK2S upgrade LM8UUs bearings question

I am not sure what else besides LM8UU you expected to see on these bearings, as this is what these bearings are called. But here's a recommendation: gather up all the bearings you got, put them on one of the new rods and try them one by one how they slide across the rod. Pick the ones that give you ...
