Just installed JTech laser and can’t get the M03 or M05 commands to work.
I don’t have X-Contoller, I can get the laser to turn on manually by flipping the spindle switch in my power supply, or switching the jtech driver to CW mode. Besides that I cannot get any commands to work for the laser.
The JTech instructions are bypassing the “spindle” switch.
The black and yellow wires referred to are just to the left of your hand in the picture. You use the yellow and black wires coming from the connector that has the homing switch inputs in it. That connection is the PWM output that controls either spindle speed or laser power level.
If the switch to the left of your hand turns the laser on then you have the laser hooked up correctly.
If you put the black/yellow wires to the left of your hand into the “spindle” green connector that is in front of your finger then you should have Arduino control of the laser with the switch in the “logic” position. Black goes to “Gnd” Yellow goes to “logic”.
If you also have a PWM controlled spindle it gets a little more complicated.
I was able to get some connectors soldered in, I’ll give it a try here shortly and if I’m still having issues I’ll post some photos of my setup. Thanks,
Since you are using PicSender, let me help you with your settings. If you haven’t upgraded to PicSender 2.7.9, now is a good time to do it.
Put these files, which are edited to fit your system, in the following directory: (over write the ones that are there)
C:\ProgramData\PicGRBL Laser.txt (1009 Bytes) Spindle.txt (1.1 KB)
Launch PicSender, Press the “Open” button
press the gold “GRBL” button at the top of the screen
check “Use Auto Settings”
press the gold “Return” button at the top of the screen
Now you are set up so that you can switch between laser and spindle with optimized settings for each task by just selecting the appropriate button on the startup page (either “spindle” or “laser”).
If you use a different sender program, other than PicSender, make sure that you leave PicSender with the spindle/laser selection set up for the job you are going to do next.

Thanks Larry you have been a ton of help… I’ve got it up and running, still working on some feeds and powers but my wife wanted the Dr. Evil “activate the laser” for a picture so here is what I’ve got so far!
Hey quick question, everything seemed to be running just fine with the files i was producing, i took a break, now i come back and for some reason at the beginning of my engravings my Z is moving, like down .5"
Only change is I tried running Phil’s power test file, saw the Z was moving so i stopped and tried to make my own , now my Z keeps moving on my files
Probably not your current problem, but I would recommend that you go to the page where you downloaded my version of grbl and pick up the post processors for Vectric products that are posted there.
@LarryM I’m having the same issue only with the X-Controller. I’m able to create gcode in PE6 and run it in PS. I haven’t been able to get M03 SXXX to turn in he laser for focusing. I’m sure it’s because I have missed something only I don’t know what it is. Please ObioneconLarry. Your my only hope.
If you don’t need spindle speed or feed rate over-ride then I suggest you load this version of grbl on your machine. Since you are using PEP6 load in the version with the 1ms Dwell.
If you use Vectric products go ahead and pick up the post processors that are available on that page.
We can make 1.1f work if you need those functions.
Grbl does allow modification of the homing cycle. It is a compile time option, so to change the sequence (eliminate Z) you would have to modify grbl and rebuild it.
