The scooterengine of the X axis (the axis passing to the link and to the right) continues to hang in the step of 1mm
The motor makes a humming noise, but the motor shaft does not rotate
Give your engine the command that he should move 10 mm than the motor moves first with the humming sound and then runs to the 10 mm step
The printer will print the extruder must run to the left, but the engine will not see him back to the right.
The shafts fit into the bearings
The belts are in the right place
Gears are in order and are stuck on their axes.
The extruder can freely move (is not terminal)
The printer has done well but not anymore
And after much searching we found out that the X motor stops running on the step 1mm.
We will post a video
but the problem is that the printer now anticipates
not to come back to the engine body and the 3D model is running out
also click the motor with some success
Hmmm… There seems a language barrier, but by your username I assume your dutch? I don’t know if it’s an issue for the moderators if u explain the issue in dutch? Because i can’t really make anything about the explanation.
By looking at the image my first thought would be a loose pulley… (At least if u had any successful prints in the past???)
Try to print the Axle calibration tool and calibrate the axles? And check for loose pulleys. Not able to print anything? Loosen up the pulleys And loosen the steppers so the Belts aren’t under any tention, and move the head a few times around until every linear motion you make is smooth and requires no force AT ALL, then look how everything is aligned to each other and try to get them as straight as possible… get 2 things of the same length? “Steeksleutels” work also… and tighten the pulleys afterwards, pull the steppers a little downwards and tilt them a little upwards so the belt doesn’t grind to hard with the long belt and tighten the 4 stepper screws. And make sure all your rods are oiled! In particular the 2 crossed axles.
BTW Raby has made a very nice wiki article about the alignment which is a VERY useful resource describing the whole operation in full detail. Please read that first and maybe that will help you also it sure helped me! k8xxx-3dprinters.crimed.be/w … _Alignment
I saw that you indicated, that the pulley’s (gears) are firm on their axis, but are you sure there isn’t a little play on there? It’s rather common for the K8400, to suffer from set screws coming loose after a while.
The picture you posted in dropbox seems rather familiar & in my case it indeed were the pulley’s set screws coming loose a little bit. I’ve re-tightened them all, using a bit of threadlock glue - that solved my issue at the time.
If it’s the stepper motor, as you indicated, it’s a different story, but checking the set bolts could be an easy way out…?
Hi everyone,
I have a similar problem, before the first print the x motor moved as it should do. During the first print something went wrong and I had to kill the print, after killing the print the x motor makes a humming noise and does not move at all. I tried tightening the pulleys. Since the motor worked before I thing the axes are perpendicular. Is there any way to solve the problem?
Hi,
I was printing in ABS and the base cooled down fast and did not stick to the build platform and moved. I aligned everything, I think so but still the X axis motor can not move the head on the x axis.
