@Zax The version of grbl I put on last was the 0.9i EleksMaker version you have built into your T2Laser program. Would there be any good reason for me to upgrade the firmware to 1.1F?
Been into 3D printing for a year now, just getting into laser engraving.

RE: L Cheapo 8W/Mana SE issue
@Zax I think I had already reverted back to the .9 version by the time I plugged it in the correct slot. Didn't know 1000 was max power since default is 255, I thought 255 was max (n00b mistake). Is 1000 also the max power for version 1.1f as well?
Also for the PWM I just need to solder it to the D11 pin on the nano correct?
L Cheapo 8W/Mana SE issue
Backstory: I bought a cheap chinese laser engraver off ebay. Similar to EleksMaker, but different motherboard, has one Laser 12v/5v 2wire port. I bought an L Cheapo 8w, wired it up, accidentally fried the motherboard and nano chip. Wound up buying an EleksMaker Mana SE since it is an equivalent board to what I was running.
Anyhow I got my Mana SE board and am having issues with the L Cheapo, the laser only has a positive and negative wire, I can also run a PWM wire to it, but haven't yet.
The issue I have is that once I hook power into it and hit the power on button the laser stays on full blast and won't turn off or vary power. This is when I have the laser plugged into the "Laser" spot on the motherboard. I tried using T2 Laser to override it as well as use the M commands to turn off the laser, nothing worked. I also tried plugging the laser into the servo port as I'd seen other lasers plugged there and the laser just remains very dim and won't fire. I also tried the motor port (as I read in another thread) and the laser was a little dim while at rest and fired where it should, however it didn't fire full power like how I had it set (this is exactly how the laser acted in my original board, very under-powered and the original .5w laser I had did a better job). Also on the original motherboard when I had the PWM wired in the laser wouldn't turn off so I had to disconnect the PWM wire and run in dither mode instead of grayscale.
I thought this might have been a firmware issue. I had grbl 1.1f on it initially, then reverted to 0.9j, still happens no matter what version I use.
Any ideas of what is wrong or what I'm doing wrong? Is this a setting in the firmware or do I have the laser plugged in at the wrong port? Does it need a PWM wire ran to counteract it being on?
