LaserTree K60 problems

I’ve just installed LaserTree K60 on my AltMill, followed all videos and instructions. The laser works.

I have a few problems:

  1. Spindle/Laser selection dropdown shows only default spindle. If I click on it it shows “No Options”. Default spindle is set to H-100 (2.2. kw from SL), spindle 1 to SLB_LASER. I can set default to SLB_LASER and it will work, but switching with hard reset every time is, obviously, a no-go. Tried different combinations of default spindle and spindle 1,2, set it to different things. Sometimes briefly it would show the dropdown, but after restart it goes to default spindle only again.
  2. After using laser spindle does not work. It shows “spindle on”, but it does not turn. I saw that there was a bug in firmware 6 months ago. Does anybody know if it was fixed?
  3. When I switch SLB-EXT off with the switch the laser starts to fire in pulses like every half a second! I switch SLB it on and it stops. It looks like even when the board is switched off there still some current leaking to the K60 adapter board and it fires the laser. Very scary and dangerous.

Does anybody have any ideas how to fix that?

Thanks

Are you using the latest firmware from 20260525? I thought I recall an issue with laser in the previous version.

No, even though I’ve got the machine just a couple months ago it came with 20230917 firmware. Do I need to flush it with the latest one?

BTW the issue with the laser firing by itself seems to be related to LaserTree. If the adapter board is disconnected the laser fires. I briefly checked SLB-EXT laser output with oscilloscope; it seems to be normal and there is no output when board is switched off.

It is likely not be related then but anyone trying to help diagnose the issue would likely want the latest firmware flashed at least to rule that out.

@novos40 FWIW, I have the lasertree 20W v2. I believe that it is a well made unit, but I had firing issues with it early on. Unfortunately, I bought it from amazon and didn’t get to test it until the return period was over. I went back and forth for weeks with lasertree support. I will say that they were responsive. However, all they ever did was ask me to conduct more and more tests. These tests required me to have an oscilloscope and a volt meter, and be willing to make test wires. I have the volt meter and would have been willing to make test leads,but it was clear to me that their tech demands would never end. So, I told them that they had achieved what I believed was their objective. I gave up.
I got help from another member here, who is an electrical engineer and who had helped me in the past. With is help, I got mine to work.
My only advice is to return it if you can. Your problem is not the same as mine, so my solution - which I seem to have finally found - will not solve your issue.
I’m sorry that I cannot be of any help.
