Jerks at full speed on Y axis

[Aiph5u ((not affiliated with Onefinity))]

Hey Guy,

@Aiph5u

Onefinity provides a help file which deals with many kinds of erratic movements of an axis:

• Troubleshooting: Rail is getting hung, stuck, or out of alignment

I would check all points one by one to see why your carriage seems to loose steps.

There are three causes that are not mentioned in the document above:

1. Should your machine not be properly rectangular (“squared”) and coplanar (not twisted), the Y movement can block.

   Have you ensured accurately that your machine is rectangular (“squared”) (➪ bar gauge) and coplanar (“not twisted”) (➪ fishing line method)?

2. And the second possible cause not mentioned in the document above is: This mysterious issue some time ago.

3. Electromagnetic interference (EMI), as e.g. mentioned here.
