Bigger project area and wobbly lines, louder mirro after system meltdown/reinsta

Hi, I'm not sure if I need to change openlase or the lasershark or what, but when I was messing around with playilda I really corrupted my packages and linux. After trying to reinstall linux about 8 times I finally have a version of mint, except this time I am booting up from something that's like /vmlinuz (the only install of linux i could get to work this time was using ubiquity -b to install)   and I don't know if this has to do with that either.

But I've tried compiling the forks by marcan & kamal and for both of them the lines of my laserprojector are extremely wobbly and far apart.

The projector is covering a much bigger area than before, and I think the galvos are louder than before. Do I need to reset something? I've spent days just trying to reinstall to get to this point and I need to be able to demonstrate this tomorrow to get the safety ok from my school. Thanks!

If you have only been tinkering around with linux and not the hardware then this should be a purely software-only issue.

Louder galvo noises and wobbly lines can both be caused by setting the sample rate too high and by increasing the scale in the output window. I think one of these is your issues.. probably the latter since you are commenting on scaling.

Loud noises and wobbly lines can also be caused by improper tuning of the galvo amplifier boards or by fried galvos (generally caused by driving them too hard for extended periods of time). You probably don't have this yet unless you have been tweaking the pots/etc.

landshark:
Thanks! I haven't tweaked anything and I tried lower sample rates, I didn't see any changes. I've never had the sample rate higher than my galvos are rated. The output is still really large and crazy wobbly. I can make the square smaller or use an aspect ratio in output but the lines are still messed up. I'm trying to install linux on a borrowed laptop right now to see if it will work on that.

*the linux install is not working on the other laptop. And tbh I felt like the gui of everything was a little different this time, like the grid on output was bigger, the buttons seemed a little sharper on the corners than before, it was strange. I don't know if this could mean anything?

landshark:
If I left my galvos plugged in to power when I wasn't running them would that have fried them?

Stimpy:
Maybe it's wrong audiosetting in qjackctl. Or some strange audio connection.
