Single layer shifts- can I use a belt tensioner?

[helix_3]

I have been getting layer shifts recently, but usually only 1 or 2 layers before correcting. It also always happens in the X direction, but not the Y direction.

Re-tensioning the X-axis stepper every week seems to help. Can I use a GT2 tensioner to help keep tension constant?

Double check that your set screw on the belt pulley is tight. Second, move the x back and forth and make sure that it isn't binding.

Use z hop and slow x y speed down to 200 and report back if problem still persists.

Yes i agree with both these guys. unless your belt is really loose then thats not the issue.

Indeed, tighten the x-motor's set screw down and loctite it down for good measure. I had this problem, and that resolved it.

Okay, set screw is tightened, loctite is applied, binding isn't present, and I'm already printing at sub-100 mm/s speeds.

try swapping the x and y connectors where they plug into rambo. see if the problem follows the axis.

have you changed the firmware recently?

After strengthening the x-axis hub's connection, there appeared to be an immediate improvement in quality.

If the problem re-surfaces, I will try the connector swap. Also, I have not changed the firmware recently.

Its not the belt but the extruder stepper is not fastened enough!
