[What are these plugs called, I need replacments. (hotend)]

hi guys

 

these two plugs have worked themselve through the wires so I need to put replacments on.

 

I need the names of pins that attach to end ends of the wires and the connectors, any ideas?

 

Thanks in advance!

 

Will

 

 

[UM1 looses X position about 23 hours into print]

It looks like the print has lifted off the bed quite a bit. Is it warping to the point that the head is catching on some part of the print, and so not able to move correctly at some point. That will cause it to lose track of its position.

Other than that, have you tightened all the pulleys, including the one on the x motor? Also, with the power off, try moving the head around by hand, and see if you experience any areas of tightness or binding. Move the head back and forth while looking at the back corners where the short belts are. If the belts are properly tensioned, they should be running nicely in their grooves, staying totally straight, and you shouldn't see any sign of twisting etc. Indeed, if you half-close your eyes and squint at the belts you shouldn't really be able to see them moving at all (aside from any writing that might be moving in your field of view).

 

I see the part is lifting off however this happens during the first part of the build and stabilises later on (within the first 30mm)

All belts are properly tight.

 

[UM1 looses X position about 23 hours into print]

Hi Guys,

My sometimes tempermental UM1 has been printing some 70mm high casings for the last two weeks, they are 24 hours prints. About 23 hours (at different heights, normalls around 63mm) into some of the prints the x stage moves and the print continues as normal but a random amount ofset, sometimes I manage to catch the problem and can manually more the printhead back to where it should be,

I've tried all the belts, different versions of cura, different files, I'm stumped as to what might be causing this.

Here's a video showing what happens and three prints I've managed to save.

Cheers guys!
