Hi – I’ve been able to get the grbl shield up and running without any issues – great work! I’ve been testing with some steppers of unknown specs. I thought they were 12v but I’ve been able to run them at 24v and achieved much higher torque as a result.
Neither the board or the motors get hot but it did get me wondering about the heatsinks I’ve seen mentioned here in the forum. I’m confused about where/how they would be attached. The surface mount chips are so small/nothing to attach to so I’m wondering if I misunderstand what is being referred to @ heatsinks.
My other question: the Red LEDs.
(I’ve seen a ref to Green LEDs but maybe that is a later version of the board? https://www.synthetos.com/topic/grbl-shield-how-to-make-it-running-2/)
Anyway, any command will make all three LEDs light up – even if it is only a cmd for one motor (e.g. g0x1000). With a motor attached, the LED for the motor that is moving will pulse/blink. Is this all on/pulse the expected behavior?
