Anyone know how to fix this drifting in the y axis? The x seems good and so does the z. Any other suggestions based on the photo would be appreciated as well.
Are the belts tight?
Yes @Thomas_Cox the belts are very tight. you can see it getting a little better towards the top. But it still isn’t right. Do you think I have my stepsticks power too high on that axis?
Also controlled the gears of the steppers?
I don’t understand what you mean by that?
Sorry, i mean belt wheel
Check that the gear isnt slipping on the the stepper motor shaft.
I’ll check. Any other suggestions? Could it be that it is skipping a step?
It looks like the first few layers are ok, then there is a steep slope. To me this indicates a heating problem, a shift I. The base part or…is the nozzle hitting it?
I had a problem where the belt was too tight, it grinded in the inside a bit and afer some prints it became very hard to turn that motor. Then it skipped some steps, resulting layer offset. I opened up the motor and cleared the dust, and lessened the tension on the belt.
Quite possible you will probably hear it skipping. Check the voltages on the stepper drivers. Your electronics looks like the kit from china with the original arduino mega and their own copy of the pololu’s. I have one and saw it doesn’t have the volt meter header pin. For those i beleive you cam measure on the potentiometer screw as a + to get a reading. Also double check the right voltage. I had mine running at 0.4v and that is right for small motors and steppers but I had bigger ones that I run at 0.7v and they like it much better.
How do I adjust the voltage to the drivers? And yes the filament did start slipping that’s why I stopped the print.
Is this a new printer build? Is it square to the table?
Yes it’s brand new. And yes it is square
With no power on the motors, is the movement on the y axis as smooth as on the x while moving the carriage by hand?
Yes. It is really smooth.
Likely a pulley slipping, do the same print at a super slow speed and see if it continues/improves/changes.
I’ve seen this caused by a motor getting too hot, softening the printed part it was mounted to and deflecting under the force of the belt tension. It was a nightmare figuring that one out.
May be the mirror is sliding on the hotbed
Ok that problem is solved. Now I’m fighting my terrible Chinese pla.
