“Wrong Way” you are correct in two ways. One, I am sorry. I was out of line and shouldn’t have been so brash. I was frustrated by some of the questions and comments. I was not upset at anyone helping in a, well helpful way. Again, I am sorry and I could have handled it a better way. The second way you are correct is one of the bearings is frozen. I had that same problem a couple months ago but replaced them. It never crossed my mind that it would be happening so soon. Although I don’t feel like that is the main cause of the problem because the hobbed bolt turns pretty easy through the frozen bearing. But I am sure it doesn’t help.
Even though the wiring is not supposed to be part of the problem, after I changed it out(having done nothing just before that) once the wiring was upgraded, the problem was MUCH improved. BUT knowing electronic, it could be intermittent.
Yes, I did swap out stepper drivers. No I did not swap out motors yet. I was trying everything else before having to unsolder them from any of the other ones. I am going to try and repair the bearings before purchasing new ones again and swap motors. Does anyone know of a different bearing people are using that is sealed?
Hi,
I had exactly the same feed problem.
In the end i found thet the Trflon / PTFE barrel had been compressed, i had over tightened iy
This caosed the outside diameter to swell but more importantly the internal diameter to close up.
This caused the filement to be very ticht through the barrel giving poor and / or intermittent feeding.
I drilled out the barrel, assembled the hotend with extra locknuts to remove any compressive forces on the barrel
(Posted in “Parts Issues” part of this forum)
Ive had no issues since, and ive run at least 2kgs of filement through it since the modification
Also i used to pull the filenent out of the extruder when hot to change colours, this coated the inside of the barrel too.
I now cut the filenett off at the top of the extruder and push out the old colour with the new colour filement.
Usually it takes 3 prints of the 20mm cube calibration test piece
