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

Thanks for the suggestion! As it turns out, I did fry the galvos somehow. It must have been leaving them plugged into the wall when I wasn't using them. I have a spare galvo set around here I was saving for planning to do an instructable/tutorial of sorts so I went to radioshack and got a power cable and swapped them out for my old galvo's.... problem solved! These galvos aren't rated as high as the ones I was using, but at least it works!

landshark:
Does anybody know- if I fried my galvos by leaving them plugged in when I didnt use them, could I get another power supply? Would that fix it?

I think I am going to overclock my @20at galvos to perform like the @30 galvos, and choose an aspect ratio that's a little smaller than the square. Or could I use the @30 galvos with the @20 chip, or are the @30 chip and galvos fried?

Macpod:
Stimpy had a good suggestion too for this. I recall you wanting to use something that wasn't the "dummy" audio server. but the max range should not have changed as that is dictated by the lasershark and unless you tweaked the pots on the lasershark boards that wouldn't be the issue. The fact you got this working with the other galvo set rules out the lasershark pots too.


Since you aren't familiar with linux I would suggest rebooting the machine between attempts. It is possible to unintentionally get multiple jack server instances running which may lead to confusion on your part.


I don't think leaving the galvos plugged in is a good idea (reason being there's no need more-so than anything else) but I also don't think this alone would harm them unless you had a power surge... and that seems far fetched.


You can check your "fried" galvo power supply with a voltmeter to see if that is the culprit. That's a start. This is a difficult problem to diagnose over the internet with the info provided.

Have you tried running different examples too that you haven't modified?

Hi, yea I tried both the lase_demo by marcan and simple. It's possible I may have bumped the galvos by accident moving them around, but I don't see anything loose or obviously missing. I might be able to get @30 galvos by Friday which would fit my needs. Tonight I am going to keep looking at the @20 galvos, I probably won't run them past 25 or not at all to be safe. Agreeing with Stimpy I tried different settings and the 'live memory' (I'm on my phone so I can't look) checkbox bu it was the same. I made a few attempts when I was in the terminal to guess my username to add to the permissions for audio server and being live or something, but I don't see how that would effect it. I'm going to test the other galvos more tonight to rule out a problem with the software or linux- I've never booted from vmlinuz (virtual kernal, I can't boot from the hard drive.) it's looking good though I have to @20 galvos. I'm also going to research scripting linux to run examples together on their own and some other things. That's a good suggestion I will try to find a voltage meter. I'll keep looking at the jack settings too.
