As noted in another section posting, I’m trying to get my JL1 laser machine operational again. I have replace the failed Laser modules with a LaserTree LT-40W-aa and the controller board with the FluidNC TMC2099 Pen/Laser board from Bart.
I have spent a bunch of time trying to get the config.yaml file to actually do something with this hardware and so far have only succeeded in learning a WHOLE bunch about yaml, FluidNC config codes, tried several different config files. So far, I still have a paperweight.
So here are two files, one is the config.yaml and the second is the report I get when I restart the machine and it reads the config.
I knew it was something I missed while moving between various config files. I’ve made the change, but i need to get the JL1 back over to my computer. My new printer arrived and I’m playing with it (Elegoo Neptune 4 Pro).
I’ll get to back working on the laser after dinner.
I was having some issues you have to have the ac power hooked up.
And also you have to unlock the steppers with a $H I believe before they will do anything.
I have mine on a sand table it works I just haven’t had time to get my end stops I fired out.
Supra Dave has helped me and I have all the info just no time for it rn it seems and it’s also kinda working so I don’t want to mess with it till winter or fall. If you want I can get my file off and maybe send it somehow
Can you post a pic of your board ?
There was two versions of it iirc. I am by no means any kind of expert on this but is your setup a corexy? And I could try and get you the yaml I am using for this board.
Okay, I see that there were several (I’ve lost count, actually), Different pin description images, and they are a little different relative to the schematic, also posted on EDA.
One more time through the yaml, line by line and we’ll see if I can get it right.
To answer a question in a post above: This is a Cartesian system, not CoreXY, one stepper for each axis, homing in the positive direction for X and the negative for Y. Both limit switch are wired NC as we do for all the V1 machines.
I’ll let you know if I make any notable progress.
If I understand the schematic, VMOT is the same voltage as the input power. Do you think the board can supply the Laser directly off the VMOT, or should I provide a separate 12v to the laser (which is what I have at the moment).
I don’t think that pen laser board has an output that can source sufficient current to power the laser.
I currently have my Jackpot/JL1 setup using power I routed directly from the power supply to the laser.
That works fine, but isn’t best practice.
The better practice would be to use an enable pin with a suitable SSR or high side switched MOSFET to switch power going from the PS to the laser. The reason is that if your PWM pin ever fails high, then your laser might get stuck on at full power- a fire and laser light safety issue.
