Laser Cutting Class
looks very promising. would it fit on the CoreXY?Question, on hat pin do you connect the laser driver? SpnEn? Could you please share your GRBL settings?Best regards.
In the GRBL settings, I had to lower the X and Y max rate to 250 so the steppers do not start to oscillate at hight speed. would there be another setting which could help for better tune? could you show your settings?
Thanks I'll do so.After installing the electronics, I realized that when using the application "bCNC" (what I was planned to use) when I give the order to the laser holder to go up, it goes up-right, or with the order to go left, it goes down-left...and so on... what should I set as parameter to make it work logically?
My mistake, as I flashed 2 Arduino's, one with your file and another with the "flat" GRBL and then I mixed the boards... :-(
Portable CoreXY Laser engraver
Hello again,How do you drive the laser? thru the SpnEn pin? Have you made a driver with some transistor?I use an Arduino uno with a CNC Shield and I bought the laser you proposed..
Bravo, splendid smart project.So I am making it... At the point to add the electronics.I added end points switches, but I do not know here the Zero side (XY) is and I would prefer to know it before entering a home command. Can you help?I saw you added the engraver option, which is absolutely great. my only concern is that I find the shafts supporting the spindle holder not rigid enough for engraving. I would suggest to add another shaft behind the two others... I'll try this in next step...Where can I download your spindle holder?Bravo again and many thanks
Many thanks for your answer, I'll go on with the laser configuration and top there awaiting your new deign...Best regards.
