It's been so long since I've used my laser I'm of zero help here. But isn't the MIN/MAX values backwards?

i kinda thought the same thing at first but i double checked the instructions on here and thats how its says to put it

That pic in the instructions does t really show a complete configuration. 30 is in the minimum field as a suggested min for Grbl hex files using 255 as the max intensity. Max should be higher than min. Your laser on command should also be just S not S11000.
Which hex file did you load?

i thought it seemed kinda weird that the max setting would be zero but i just went with it. So should i have it set to 255 and 30? also when i just put in S for the laser command it would run the program but it wouldnt ever turn the laser on. the hex file i loaded was just the one on the instructions. my understanding was that the laser was PWM and that the X and Y axis would run smoothly and the program would just pulse the laser to different strengths to create shading. the X and Y axis are running very jerky and i assume because i had the laser set to S11000 it was just keeping at the same intensity?

I bet you've got grbl 1.1 with Carve King settings. Can you type $$ and press enter and then copy and paste the settings? We might need to just get that one file adjusted to your M3.

yea it looks like my settings are all messed up. do I need to put them back?

Just make them match the M3. That's grbl 1.1 which is fine, it just has the Carve King's settings in it. That's why your M3 is running funny. Just change these settings to look like this and you'll be A ok:
$100=40.000 (x, step/mm) $101=40.000 (y, step/mm) $102=80.000 (z, step/mm) $110=8000.000 (x max rate, mm/min) $111=8000.000 (y max rate, mm/min) $112=3000.000 (z max rate, mm/min) $120=250.000 (x accel, mm/sec^2) $121=250.000 (y accel, mm/sec^2) $122=250.000 (z accel, mm/sec^

Attachment DeletedI think that kinda worked but when I ran the file it came out very very light. like barely able to see it and you can see individual lines like its still pixelated. I have the laser height about 1 1/2 inches off the surface and I even slowed the feed rate down to 900 thinking that may help. these are my settings in piclaser

this is at a 250 feed rate. that slow I would think it would be insanely dark Attachment Deleted

As I said I can't really help here but I'm curious, does changing the output to GRBL make a difference?

I'm not sure how relevant this is, but you should have the g code type set to "Grbl" instead of "Standard G Code". And one more thing I didn't mention if you are going to do pictures is to set laser mode (setting 32) to 1 like this: $32=1 I'd suggest experimenting with some vector line engraving as you grow accustom to laser power and feed settings. Processing images and creating settings for them can add additional lasers of complexity (IE: the underlying image and the efficiency of the g code sender come into play). I'd suggest running the same file you just had with that $32 setting set to 1. If still unsatisfactory, step back and experiment a bit with vector line engraving using the inkscape laser features talked about here: millrightcnc.proboards.com/thread/531/video-tutorials-running-millright-machines. See the video called "Generating g code for your laser." From there, you might want to contact Pic Engrave and let them review your image and make setting suggestions for their program. They are familiar with the JTECH system.

yea I had the $32=1 in there and grbl code I was just trying anything I could think of. I did a simple "TEST" text in inkscape like in the video and you cant even see anything is there. its like the laser is at a fraction of the power it should be. in the code I can see it goes to 11k which should be close to max power. it looks like the program is running correctly.

It should engrave a lot darker. Let me take a look at your g code please. If I don't spot anything wrong in the code I'll get with JTECH Photonics to see if they have suggestions or need to physically examine it.
Regards

here is my gcode file for the "TEXT" on inkscape and also how it came out at the exact same settings you have on the video. text_0001.txt (1.22 KB)
