HELP NL Utrecht PT-30K driver suddenly stopped

Just testing my new easylease II usb when doing so suddenly 1 galvo stopped.
I disconnected everything and started troubleshooting.

The galvo is ok, because if i move it to the other driver it works.
The input from the ilda boad is ok because if i feed it to the other driver it works.
So the driver stopped working, there is a fuse on the board and if i put a multimeter on it i see different values but as far as i can see the wire is intact.

Is there anybody withing the Netherlands Utrecht region who cares to help?

I have a school disco on friday for my kids where i have to show up with a working driver.

Hi Michel,

This sort of thing, a hardware failure just before a show happened to me about 2.5 years ago.... with me a galvo began to send smoke signals with no reason and no overdrive..... Always a bad thing...

For the fuse on the board, can you take it out and measure it with your multimeter on 'diode' setting to see if it still conducts ?

I might have another spare galvo set (LW45k) to help you out, but I have to search and test them if they're still ok. I live in Eindhoven, if that's not to far from you :)

Hi Floris, thanks for the suggestion, i also spoke to Martijn, i think his alias is LedFreak3D from Hoorn, i payed him a visit and he offered to take a look at the driver.
Can't wait to hear his findings.

Martijn, if you read this, thanks in advance, nice to meet you :)

It's good to get to know the dutch laser enthousiasts more and more.

In a day or two i hope to know which course to follow.
I already informed the organisation for the Friday event that it might be a no show, would be nice if i can make it.

Just sad i cannot play this evening with the new dac :mad:

just received an email from Martijn that he fixed the driver and he sent me some pics, see for yourself.

:o:o;);)

apperently the opamps were toasted and the fuse was blown, i can pick them up again this afternoon, will be back in business before friday.
perhaps scan angle and speed was a bit enthousiastic or just bad luck.
