Love how you just casually make a darn nice piece of furniture for a laser
Thank you!
I love your take on the laser cutter. You did something new bold unique and different. I like how you shared wiring and light burn. I use the same board with fluid NC. You may want to store everything on an sd card. A few times I just powered off everything and the config file get lost. On my mac I like lightburn for modeling and designing. For quick cuts i like laser grbl its simple and easy to connect.
Thank you very much! And thanks for the heads up regarding the config. I export the lightburn settings and store them on the git repo just in case I need to install on a different machine I didn't know that the settings could be lost that way. Yeah lightburn is great, I'll have a look into grbl laser too. Cheers
Does FluidNC works with lightburn?
@@herberthenri FluidNC is the next iteration of grbl ESP32 so it should work fine with the grbl version of lightburn
Great job!!!
Thank you!
Can you also add wiring for the DLC32 to the laser PSU if one wants to use the touch screen connections? Thanks
Decent design gantry might be a bit heavy with the rail or is the vibration not an issue at high speed?
You also might want to reconsider the high voltage side of things, enclose the PSU, laser tube and the wiring in metal and ground that.
Couple of kilo volts can easily kill you if it arcs the wrong direction.
Vibrations have not been an issue from what I have observed, 250 mm/s on engraving. Thanks for your suggestion! The aluminum frame was filed to take off some paint at the joints and grounded (verified with a multimeter around the frame) PSU and tube can't be accessed without removing the panels. Appreciate your input, cheers
how do you sync the 2 motors...X one is nema 17-20 tooth, Y one is nema 23-32 tooth? is it a software configuration like you did for the 100 mm test?
X and Y can have different teeth as long as the steps per mm are set correctly in the machines definitions file. The Y axis has two motors driving it and it can't have different numbers of teeth as it moves a single beam. The pulley in the vid was probably a temp until the correct one arrived as the X and Y axis both have the same steps per mm and it's been tested to be dimensional accurate. Nicely spotted ! Cheers
Can u show engaraving at high speed (400-500mm/s). I had a lot of problems whit that controler when engraving.
I engrave at 250mm/s @20% power- No issues at that speed. But you have to consider the acceleration values to compare our speeds directly. Cheers
do you have a parts list / instructions?
Not at the moment unfortunately all the info I have is on the repo for the project (which has the CAD, wiring and firmware). I may add this later.
Do you have your repo link please
