GRBL plotter with laser #393

Closed Marmadoc closed 6 months ago

Marmadoc commented 7 months ago

I read that GRBLPlotter can be used with laser as well. I like to try it. I have LT-80W-AA PRO laser by LaserTree. I have laser module - 3 wires, and laser module driver adapter P-DA-01 with two wires + Power 12V. It looks like two wires are Signal and GND. My question is can I use it with CNC shield V3 - like with servo Z+? I understand I have to change GRBL setup - but will be OK with GRBLPlotter (instead of servo)? Thx

Yes you need the "regular" grbl version which creates PWM from 0% to 100% - https://github.com/gnea/grbl I have the hex here: https://github.com/svenhb/GRBL-Plotter/blob/master/Firmware/hex_files/grbl_v1.1h_config_A.hex If you use the servo-grbl version your laser will be very week. Servo uses 1ms - 2ms high / 20 ms low, which results to an energy of 5% to 10%.

Here I combined plotter and laser: https://youtu.be/Ebe2kFlE058?si=TBMYBpiT18W6Bk85 But pen is controlled by Z axis, not servo.
