Re: Unable to remove heatsink out of MK3 extruder

Thank you, Neal and Robin! I used even more brute force and it came out. I think the plastic parts were either badly shaped from the start, or they warped later on. The PTFE tube was not stuck. Unfortunately, the clogging has recurred after cleaning the hotend out. I think it might be the filament. ...

Unable to remove heatsink out of MK3 extruder

My MK3 has a clogged nozzle and I want to disassemble the hotend. But I cannot remove it from the printed parts. I am stuck at the part shown in this video: https://www.youtube.com/watch?v=DSwqr9l4_kM Unlike in the video, my heatsink does not come off the extruder, I have already used somewhat 'unre...

Re: Hotend turns off randomly

A new heater element will not fix the problem. I would probably avoid taking the entire cable bundle apart to prove that, and just plug the new heater into the Einsy and into the extruder, but leave the printer otherwise assembled. If it turns out that the new heater does fix the problem, then you h...

Re: Pinda connector with 4 pins instead of 3 ???

Strange that they have a 4 pin connector on the board and in the manual pictures, but ship a 3-pin terminated PINDA. I have no idea how I convinced myself that the PINDA 3-pin cable was plugged in properly when I initially assembled the MK3. There seems to be no way to do it again without cutting of...

Re: Hotend turns off randomly

Where did you measure the EINSY output voltage? I stuck some jumper cables in the plug of the cables running to the hotend. So it's not a broken cable to the heater. I don't understand the software or electronics, but while you are waiting for more informed members to chime in, here is what i think...

Is your PINDA connected like this, and does it not respond if you hold a metal object against the PINDA sensor?
It is connected like this, and there is no response when metal comes close to it, because the light is not on in the first place.

Where did you find that photo?

Re: Layers misaligned

I have seen this problem a few times when using an older Slic3r version on the MK2 printer, but not yet on the MK3. On the MK2, it was due to some nonsensical, but programmed extruder moves around the edge of the object close to the left or right side of the print bed. If you open the .gcode file in...

Re: Filament stops loading mid-print

Sometimes this is cause by the PTFE tube not fully inserted into the heat break, or it's end is damaged.

On the MK2, it was also sometimes due to incorrect tensioner spring tension, but it seems the MK3 is much more tolerant in that respect.

Re: Filament and PTFE tube jam

I think you need to dis-assemble the extruder and replace the PTFE tube, or at least inspect it and 'repair' if possible.

Loosening the idler tensioner screws will disengage the extruder motors hobbed pulley from the filament, but if the PTFE tube is chewed up, it will probably not help by itself.
