LightBurn + Atomstack A20 MAX - Engraving Accuracy

Dear baricl1317Loren Baric, Dear berainlb

I might have reached to the solution,

It seems the gantry alignment was the fundamental cause,

After I found that the gantry was not exactly vertical to Y-axis, I adjusted it, but this alignment was quite sensitive and it seemed I further messed up the alignment as below:

So I caefully re-do this again, and made the gantry (X-axis) as vertical as possible to Y-Axis, and tighten the 5mm shaft (which connects the gear of left/right Y-axis)

Then the result came out like below:


*Left is after alignment and right is before alignment

To me, now it seems almost certain that this was the fundamental cause, as on initial assembly, I attached and tighten the shaft without any care, so the misalignment was there since then.

As the Atomstack A20 MAX has a wider working area of 850 x 400 mm, probably this machine has a more sensitive nature of aligning the frame and the gantry.

So if anyone facing the similar issue, the possible clue can be as below:

Of course, if it still doesn’t help, a lot of idea was provided in this thread, such as:

  • Belt Tension
  • Pourley tightness
  • Software
  • Backlash

Anyway, I will monitor the behavior of my machine further, and report again before this topic is closed, to confirm if the solution/assumption above is correct or not,

Loren, berainlb, Thank you very much for your patience and kind support, I couldn’t have made all these myself and I am very happy to be a part of this community, hopefully in the future, if anyone faces this same challenge it could be a help and you both made that which is greatly appreciated,

Best regards.

it is now working perfectly, defect seems to be solved, thanks again all who advised me, Regards.
