Laser cutters warp/distort output seemingly randomly #974
I referred to this as an ongoing issue, it's one that I've been aware of ever since joining DoES however Adrian pointed out that one had never been raised on github
I'll update this with more images that demonstrate the issue as they happen.
@magman2112 Has suggested to me in the past that this may be a problem with the USB Serial connection, however this happened a week ago to Paul (unknown second name).
He downloaded the data, started the cut, the result was warped. He then pressed stop, flipped his wooden piece, then started again. This is without re-downloading the file or altering the data in the laser cutter's ram in any way, and the result on this second cut came out just fine.
The image in my post may be unrelated currently, and more related to the maintenance applied via #968 but it brought up the issue in my mind, and I'll post more images and evidence of what I'm describing as the incidents occur.
I'd propose that these issues are a combination of the wheels the sled runs between note being brilliant, plus the belts are probably getting old.
New belts are cheap and a bit of modification to make the belt tension spring-loaded would probably not be too difficult, the sled delivers no "power" so the belts only need be tight enough to overcome the momentum of the sled while reversing.
