N1 Layer Shifting

Postby dsiegfried » Fri Apr 22, 2016 8:15 pm

I know this has been discussed before on the N2, the layer shifting can be eliminated by slowing the printer down, but it's frustrating to not be able to run it at the speeds it's capable of. This is only running at maximum speeds of 65mm/sec, the machine is capable of much faster speeds.

With the N2 they said to remove the electronics cover but what about with the N1?

Check all the grub screw in the pulleys, some can be loose. But that ringing though, not pretty. Can you feel any play in your printhead?

No play in the printhead whatsoever and I have run much larger jobs with no layer shifting at all. I don't think it's loose hardware, I think it is stepper driver error.
By "ringing" if you mean those artifacts around the holes, those are par for the course with parts that have holes.

Normally the layer shifting goes away if I slow down the speed, but I just started the job again at 60mm/sec, and the layer shifting is still there.

Layer shift is at the same way, that indicates that a pulley is loose. I would check them to be sure.

I'll check all the pulleys and set screws before the next run.

For N1, the electronic box is outside the chamber so it is less likely to be affected by heat.
Check the mechanical part first (all screws and belts on X/Y gentry).

@John@raise3d,
I recall a mod to the voltage for the stepper motor being previously posted. If I recall correctly, lowering the voltage would increase the stepper motor torque and the motors temp. Is this correct and how can it be done?

Yes, lower the voltage of A4988 stepper driver to avoid grinding. I will email you the instruction.

All the pulleys and set screws are tight as a drum. I ran the same part again and still having the same problem.
I even added a fan below the electronics to make sure the board stayed cool.
And the layer shifting is not all in one direction, there are shifts in both directions.

Do the printhead move freely when pulling it gently by hand? I have taken my printer apart and i had to do some fine tuning when putting it together again to make it move freely as before. Worth checking.

Just replied to the ticket. Please check.

Hi I wonder if they solve your problem in the ticket because I get shift problem also. And, I can not find the reason why it happens after check everything.
