Hi, Have anyone tested RS-CNC32 hardware capabilities in terms of speed and accel to use with laser? I mean, what are the highest values so that hardware (belts, 3d prints etc) will handle without too much steress? The design is rather not intended to be used with high accel rates but I bet somebody...

I don't quite understand the logic behind this, but once I changed the pull up resistor to 10k, the laser stopped to turn on randomly once idle. I have no idea if it limited the currect enough not to start the laser and at the same time is still enough to keep the pin state as high or whatever else ...

Hi spons , Could you try to add a 1k resistor between 5V and S (pwm) for you mesurement ? See U Yes, in the mean time I found few of the topics on French section using google translate that pointed that out as well, thank you :) This has partially solved the issue. The laser turns on while gcode is...

Ok, I did check and the board does not provide any voltage between pwm spinle and gnd pins. I only measured with voltmeter but I guess the volatge does not fluctuate with 50kHz for the meter not to capture the changes. Also, when I connect the laser PWM pin to 5V (next to spindle gnd pin) the laser ...

Hi, I have installed a laser module to my cnc (v1.0 grbl board) but can't get it working. Reading the manual, I have updated STM32 firmware with the one form "Easy Install", upon checking the versions it says 1.1f dated for 2018 (I don't know if this is correct as the manual says that it s...
