Well, everything i touch seems to be failing at the moment []
I've been doing some work on my 8W projectors, swapping out the DPSS for DI greens.
Just went to power up to start dealing with the optic placement and my X galvo isn't moving.
I am running Scannermax 506 with DT40 amps that were modified by Bill Benner.
So far I have checked:
Fuse - good
Swapped galvo cables at the amp, the problem stays with the bad amp, so rules out galvo and cable. When powered the X galvo is held still by the amp but it doesn't move.
Swapped power cables from PSU - the bad board stays bad with the good power feed connected
There are 2 green LEDs on these boards, on the bad board only one is lit, but I'm not sure if its always been like that.
Can anyone who is familiar with these tell me where to go next please? I have a reasonable DMM, but no scope. One for Mixedgas perhaps?
