Problem Type: Equipment
Workspace: Lasers
Asset: Dorian
Summary: Y axis issue
Additional Info: Came in early to use Dorian and I can’t move move the head past a little more than halfway down the y-axis. Shapes cut seem to be squashed in the y-axis accordingly. Normal/rotary switch is set to normal.
Report generated from a filing. This report has also been sent to Asmbly staff, leadership, and space leads with any contact info that was provided. Provide additional photos or resources here to help. When the problem is resolved, ensure it is marked.
When this happens, it’s a saved state within Dorian’s controller causing the problem.
It’s fixed by turning Dorian on, opening the rotary menu and turning rotary off (if it’s already off, turn it on, then off) and clicking save, then restarting Dorian.
What lightburn shows in that rotary menu isn’t so important, because the “cache” is actually on the machine, not the PC.
Later today I’ll get a video uploaded to YouTube showing the process, make a wiki page for it, and put a sheet of paper with a QR code to scan to view it in the space. Sorry for the trouble!
Do the computers still imaged to when you restart it everything is set as it should be? In other words it trashes any saved libraries and settings? Some people do not know the rotary settings. I usually if I run into problems just restart the computer and laser at the same time to rule things out. But I haven’t been in a few months.
Yup. This is what causes the mismatch when folks open lightburn and see “disabled” on the rotary menu, even though the last state pushed to the machine was “enabled.
Thanks Nick. In this case fortunately someone came by who had seen this before. They fixed it by going to Laser Tools → Machine Settings in Lightburn and scrolling down to the Rotary Mode setting which was ON, and toggling it off.
Somewhere I should mention Dorian’s motion components are in pretty bad shape. That constant grinding sound is not normal. I’m really not a fan of linear rails in lasers due to contamination, and I suspect these are super contaminated.
Simply adding lubricant to the rails is unlikely to help. They most likely need to be taken off the rails (yes the bearings have to be handled carefully or they spill everywhere) flushed, and re-lubricated, but getting them off the machine is a significant undertaking. There may be an easier way but I’m not sure if it will work.
It may need bearings replaced- we have those on hand.
The red/orange switch we added on is blocking the gantry travel and limiting how much bed the machine can use. It really needs to be relocated out of the path- or another switch solution could be nice too.
Its tube is pretty heavily degraded and should probably be replaced.
