New here - problems, but semi-solved, with ULS M-300

[Ian Stewart-Koster]

Thanks for the ideas Scott, I appreciate your reply.
On small or thin acrylic, eg 3mm there is no problem.
ON 10mm, there had been a noticable lean to the left on pieces cut., as if the bean was not vertical, but left & right edges had a leftward lean, front and back were OK.
I agree, it is as if the beam is off centre just a tad, but the lens does not seem to be adjustable.

I am sure the bearings and belts are OK.

I spent 7 hours yesterday cutting 6" letters in 10mm acrylic with it, and it was fine, except for the noticably smaller front face, but I was glueing 3mm acrylic over it, so it looks fine with a face overlap of a small amount. 100% power, 0.8% speed, almost 6 minutes average per letter in 10mm stuff.
The start and end points were not obvious at all this time.
Whereas last year they were a defuinite bump as if there ws potential slop or drag/friction in the system.

So far so good - it must be a lead to plug connection I'm thinking, that was the cause of the main problem I had- and after sitting overnoght to settle, it comes back to good again...

Thanks again

Hi Ian, the lens isn't adjustable, you have to adjust the beam through the #1 and #2 mirrors (more than likely #2). Get ULS to send you the alignment instructions. It's not difficult, just takes some patience, especially the first time.

Ok, thanks for letting me know. I figured the mirrors were all fixed, locked, and not tweakable...
I'll have a poke around.

(on a different subject, what RIP do you use for your L26500 ? We have a L25500)

I test if the beam is straight by test firing it into a piece of mdf and then without moving the piece just lower the table a couple of inches and test fire again. the beam should hit the same spot

For the record, it was a motherboard repair that fixed it... from ULS inc. great service.
