Answered Bed not moving smoothly

Hi everyone, I´m having a little problem with the bed. It will not move at all.
The bed willl move with a lot of vibrations if I manualy move it (with little foce applied). Else, it won´t move at all or hardly move.
Here´s a shot video while leveling the bed.

I already tried looking for plastic or other stuff not letting the bed move and found nothing underneath.
Thanks

 

Well for one thing your bed is traveling in the wrong direction.

For another your right Z endstop wire is unplugged.

Take the glass off and try moving it. Could be a bad bearing.

Send M119 in terminal with no axis homed, report the response

 

Got Z endstop connected (sry about that),
The bed will slightly move more when im holding the glass in the air, but not efficiently. I sent M119 in terminal and nothing changed. :S.

 

M119 should report values, like Open or Triggered. I need those values

Could be a bad bearing as I said. Does your bed not have a connector? You should remove it completely if possible since we might need to remove the Y rails to replace the bearing.

If you move the bed in Y+ does it go towards you or away from you

 

Hi, sorry for posting this late, but I had to make a trip and I just came back. I hope I can still get support..
This is the info I get after sending M119:

<-ok T:75.9 /0.0 B:22.5 /0.0 T0:75.9 /0.0 @:0 B@:0
->M105
<-ok T:75.7 /0.0 B:22.5 /0.0 T0:75.7 /0.0 @:0 B@:0
->M119
<-Reporting endstop status
<-x_min: open
<-y_min: open
<-z_min: open
<-ok
->M105
<-ok T:75.5 /0.0 B:22.5 /0.0 T0:75.5 /0.0 @:0 B@:0
->M105

<-ok T:75.2 /0.0 B:22.5 /0.0 T0:75.2 /0.0 @:0 B@:0
If I press Y+ every second, it will move forwards and backwards (one for every click)
If I press Y+ every 3seconds, it will only move away from me.
Thank you, and again sorry for posting this late.

 

Ok here's what I want you to try and do. Remove the glass bed from the printer and store it safely to the side.

With the power off move the bed front and back and see if you feel resistance or sticking. Some tension is expected from spinning the stepper motor.

If you feel sticking it's probably a spun linear bearing.

Note: The following steps are ONLY if it's sticking, not if it's tight. Don't take it apart unless you're sure of the stiction.

Assuming you feel sticking, it's a good idea to loosen and remove the timing belt. Then try again moving the bed back and forth. If the sticking goes away it could be the stepper motor.

If there is still sticking then it's probably a bad bearing.

From here you should submit a replacement part request for new bearing(s). It's probably just one side and hopefully we can figure out which.

With the belt removed it should be possible to pop off the end brackets. you will then have the individual rods available, repeat the sliding procedure to determine which side is bad. Then there are ~4-6 screws holding down the pillow block. Remove these screws to expose the linear bearings underneeth.

Note: If there's no sticking it could be stepper driver related.

With the bed removed, enable power to the printer and tell it to home. Does it make it home?

If it homes tell it to move Y100. Does it make it? Does it pause and then resume? It could be stepper driver related. If this is the case let me know and I'll help you troubleshoot stepper driver issues.

 

When I had this problem, it was the heater wire getting jammed and stopping the bed movement.

 

That's why I suggested removing the bed

 

yup yup... the wire would be all kinked and whatnot... easy kill if that's the case.
