Laser cutter status
« on: May 29, 2013, 10:37:10 PM »
The full spectrum software locks almost all the time. I loaded the software on my laptop and noticed the same behavior. When you operate the software with the printer disconnected it doesn't have a problem  with loading files, which was the extent of that testing.

I checked connections and found the power supply was not grounded very well, so I took care of that. Didn't fix the problem.

It might be a good idea to to test the internal power supply with the oscope. Make sure the dc voltage is adequate and stable.

I will not be in until next week so if anyone feels inclined, jump in and see if you can fix it.

The laser cutter is just a piece of crap. I'm done with it.

This isn't even like finding a needle in a haystack, this is like trying to find a needle in a crashed airplane.

But then you learn upon your deathbed that there was never any needle to find.

Melbourne Makerspace could use a lasercutter, even a poorly functioning one. Would there be interest in us buying the familab laser and then familab using that to get a better laser?

As we don't have a location right now it could stay where it is until the new one arrives

I'm not sure we can in good conscience sell you this one. However, I'm sure it will be discussed when we get around to having enough to buy a good one :)

Then Melbourne MS would curse us regularly. ;)

Is there a good reason why we cannot just ditch their controller board and use a setup similar to the CNC's?

Two. One is we haven't done the research into it, and the second is I've heard it's ten times less user friendly to do so, but that may be better than not working

The old logic board we traded in would be better suited for this as it supported EMC? Forgot the name of the protocol.. Anyway, the new logic board I believe lacks this functionality. Also, maybe there is something wrong with the power supply?

As I've said, it's like trying to fix an aircraft that has a cardboard frame. The foundation is weak. Which is why things keep failing. I hate this thing. Maybe we could get a replacement power supply as a start? *sighs*

What kind of power supply does it require?

It powers both the HV and low voltage stuff. I don't know the voltages off the top of my head. If we replaced it with a generic PSU, we'd have a lot of work to do, as it seems to work hand in hand with Full Spectrum's stuff.

I'll try to get in and test the power soon. If anything I would suspect the low voltage side since the laser itself seems to be cutting fine.

I don't suppose there's a schematic?
