Good day,
I have the Ortur OLM 3 10W.
When i try and rerun a job over the original the alignment is out by a 1mm or so.
No settings were changed or the board moved.
Any advice is welcome.
Is your machine secured to the worktop? Are all the screws tight?
Are the guide rails and wheels clean?
Are the belt pulleys tight?
Is the belt tension correct? Are they not damaged, dirty or worn?
Sorry I can’t help you more at the moment, but I hope one of these solutions is the right one and that you can enjoy engraving again.
Was it +1mm on the X or Y.
Did you try again to engrave and re-run.
Another possibility… What is the value of GRBL parameter $1? If power is not maintained on the motors continuously ($1=255), the gantry and trolley will be free to move within 1/4 second. Even a slight touch or nudge can move it 1mm or more.
Another possibility #2… If the parts are small, wind from any cooling or exhaust fan might be moving the part.

Hello Pete.
On both.
It is on engraving and cutting re-runs.
Hi Mikey.
I have attached the readings of the settings. Not sure which one to look at.

As to option 2… The machine is solid and do use the air assist but always have.
I do not use it on max but around 30%.
Hi there.
Yes they are clean. All screws are tight and the pulleys are tight.
Thank you for the checklist. It is always handy.
Hi Warren
Is it homing/returning to start position…exactly!
Strange its on x & y…so the shift is like 45 deg.
This is the settings for Lightburn, not GRBL.
In Console window, enter $$, then copy the list starting with $0=??. Paste that list in your Reply. These are the GRBL (controller software) parameters.
Hi.
So after rechecking all the screws and tabs and pulleys I found that the mechanism holding the module is not tight.
I tried to tighten the nuts inside it but they only go so far. I could not tighten them anymore.
This is causing the module to not stay in place but shift so very slightly.
I might have to order a new mechanism piece.
Thanks.

Nice find! If it is still under warranty, yes, get a new one. In the meantime, you might try putting washers under the head of the screws. This may keep the screws from bottoming out.
Save a couple of copies of the parameters in 2 different safe places.
