So I’ve run into an issue with my Ortur Laser Master 2 Pro S2 - LF. I’ve had it for about 2 weeks now and it’s been completely fine until the last day or two where I’ve noticed Y axis skipping lines, and now the X axis is over travelling.
I have readjusted the Y axis timing belts as that was the first issue I ran into and one side was a bit more taught than the other. I went to run a few coasters and by the time it got to the 3rd coaster I noticed the laser kept shifting up with each coaster. Keep in mind I had not made any calibration changes at that time (but it seems to keep over travelling).
Next, I tried doing a calibration adjustment to see if that would fix the problem. But now I notice my X axis is over travelling (I ask it to move to X:10 Y:2 and it moves to X:10.25 Y2).
Since I live in a basement suite everytime I need to use it I have to tilt it on its side to bring through the door and outside. I have it mounted on a thick piece of plywood.
** I forgot to mention that homing now sounds a little funny (lower pitch sound) - hence why I think this is a hardware problem
@OrturTech, Gill is the Ortur hardware guru. He’ll probably know what the lower pitched sound means.
Overtravel as you describe it, could be caused by the machine moving too quickly or trying to decelerate too quickly. This generates ‘missing motion’; are there any empty lines or breaks in your lines when engraving coasters?
Could the belts be loose or too tight and binding? I haven’t adjusted the belts on my new (to me) engraver yet - can you share the reference you used so i can learn how?
It could be axis calibration but i can’t tell yet. Can you post a picture of what’s happening?
I had a similar problem which might help, ended up being that it was the belt. I tightened it and it was still doing it. Seemed to go away after changing the actual belt itself. Just bought a roll of the belt material and cut new ones. Lines showing up on projects
Hope it helps
The next morning I tried to fix the machine with some fresh eyes. One of the wheels was loose on the Y-axis (Fixing that solved the low pitch sound when rehoming). I also noticed the actual laser head itself was on an angle as well and one of the wheels was loose on the x-axis too.
Once I fixed those, I ended up needing to create a new grid on my base plywood.
