Adjust Power levels on left or right sides

[LiquidSchwartz (Scott Ramsdell)]

Hey everyone, for work I use a Mira 7 and it’s less than 6 months old. The right side has always seemed weaker than the left especially the lower right quadrant. Now I’m also noticing that the laser isn’t cutting all the way through and I’ve increased it a few times but it just gradually gets weaker. Is there a way to leave the Left side power level the same and only increase the right side? Thanks

It could indicate that your bed, and or, laser beam is not aligned correctly. I don’t know anything about your machine, but with CO2 machines this is a symptom of it.

Hmm ok thanks, I’ll check it out

[LiquidSchwartz (Scott Ramsdell)]

Yeah I just checked it’s level

Mira 7

Appears to be a CO2 machine. Mirror alignment checking gets mentioned a lot.

I expect a fancy machine like that comes with a decent warranty / service contract. If so, that’s the right place to start!

If you’re on your own, it’s almost certainly a mirror alignment problem. The “especially the lower right quadrant” suggests you should do a careful mirror alignment followed by a “fourth corner” tweak.

Strange mirror alignment issue

I have a strange alignment issue. I think it’s machine problem, but hopefully it is fixable. All three corners, left back, left front, right front, are aligned spot on perfectly to the center of the 3rd mirror. When i move the cutting head to right back position, the pulse on third mirror is off. If i adjust the second mirror to aligned at back right same to back left, then i miss the other positions front corners Is this a guide rail issue, leveling issue or am i doing something wrong?

Not cutting the farthest corner

Hello all. I have a 900x600mm machine and it doesn’t like to cut the farthest corner, it never did cut well there. The bed is leveled, the laser is aligned but just won’t happen. Do the smoke interfere the laser path between the mirrors? [20241004_202153]

All kinds of issues with alignment

Hi all, I got my new machine uncrated and set up. It’ s my 3rd machine (the other machines malfunctioned). I’ve gotten the laser to where it’s hitting dead center in mirrors 2 and 3. I’ve watched a lot of videos and I had aligned previous lasers. Now, when trying to do the vertical alignment, that’s where I’m running into issues. First of all, I took off the focus lens and placed some tape there as I’ve seen before on videos. I did this before on previous lasers and didn’t have an issue. [I…
