E Motor Problem Hi again, last time i posted here i was asking for advice about my first RepRap, i ended up building myself a Prusa i3 Boxed =) The printer is just great, i finished it 2-3 week ago and i've tuned it day by day, in the end the printing result were realy, realy great. Now suddendly the E motor has decided to behave strangely, the problem showed up yesterday and i cant find a fix for it, i've searched on this forum and on google but i wasnt able to find anything.. Since i rly dunno how to describe the problem in a decent english i've maked a short video of it --> [youtu.be] I'm using a Minitronics with marlin as firmware, i've tried to swap the E and X connector on the board and the E stepper moved the X motor fine but the X stepper had the exact same problem with the E motor, so it seems not to be a board problem. I've tried to remove the pinion from the motor too and nothing changed, so it's not related to the hotend or something else stucked. This is still mi first RepRap so i'm not that experienced, hope someone here can guide me to a solution! https://reprap.org/forum/read.php?4,270284,270284#msg-270284 Sun, 13 Sep 2026 13:29:58 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,270284,270767#msg-270767 Re: E Motor Problem https://reprap.org/forum/read.php?4,270284,270767#msg-270767 uncle_bob Reprappers Fri, 22 Nov 2013 17:44:25 -0500 https://reprap.org/forum/read.php?4,270284,270675#msg-270675 Re: E Motor Problem https://reprap.org/forum/read.php?4,270284,270675#msg-270675

One very likely issue - the little crimp on pins in the connector got crimped over insulation on the wire.

And now it works, amazing ^^

I've unwrapped the cable and straightened them, checked the connector and changed the cable routing, and it just started working again!
I'll check component by component tomorrow to understand which one failed in the first place, right now i can only thank you very much..

Good printing to everybody and thanks again unble_bob =)]]> Nova Reprappers Fri, 22 Nov 2013 13:07:33 -0500 https://reprap.org/forum/read.php?4,270284,270608#msg-270608 Re: E Motor Problem https://reprap.org/forum/read.php?4,270284,270608#msg-270608 uncle_bob Reprappers Fri, 22 Nov 2013 09:58:10 -0500 https://reprap.org/forum/read.php?4,270284,270466#msg-270466 Re: E Motor Problem https://reprap.org/forum/read.php?4,270284,270466#msg-270466

Have you checked the wires on the connector going from the motor to the board?

mmm, not rly since all the cable have spiral wrap on them..
Well, i'll unwrap them and check when i get home from the university (tu)]]> Nova Reprappers Fri, 22 Nov 2013 03:32:45 -0500 https://reprap.org/forum/read.php?4,270284,270330#msg-270330 Re: E Motor Problem https://reprap.org/forum/read.php?4,270284,270330#msg-270330 uncle_bob Reprappers Thu, 21 Nov 2013 16:58:58 -0500 https://reprap.org/forum/read.php?4,270284,270284#msg-270284 E Motor Problem https://reprap.org/forum/read.php?4,270284,270284#msg-270284 The printer is just great, i finished it 2-3 week ago and i've tuned it day by day, in the end the printing result were realy, realy great.
