Laser with MKSDLC32 V2.1 card
I have purchased a laser (NUOF 40W laser module laser head 450nm TTL blue laser module) and plan to install it on my CNC machine. I replaced the firmware of the CNC machine.
The CNC machine is working properly, but the laser cannot be turned on. There should be a fan inside the laser, but there should be no noise or other abnormalities.
There are three connecting wires between the circuit board and the laser, with a continuous voltage of 12 V between black and red and 1 to 4.5 V between black and yellow
(PWM signal). The firmware version is GRBL (SimpleLaser1.1 V2.30-H35_2022_1223_SN_ZX_001), and the software version is
For LaserGRBL v7.12. Are there any other checks and/or settings that need to be activated before reporting the malfunction and applying for a return?
