Recently have been focusing on getting my MK2 commissioned to do some Holiday work and I noticed it was “Humming”.
Not sure why but, while it is on and connected to gSender i can not move any axis by hand. It appears the motors are locked. My Mk1 does not do this.
Any thoughts as to a fix or is this a normal thing for the MK2?
GRBL setting $1 is step idle delay and if it’s set to 255 the motors stay on. Mine is set at 100, I don’t believe I’ve changed it. You can type $$ in the console or use the firmware part of gSender to check both of your machines.
