I am having trouble with the GRBL dual endstop setup.
I have an SKR v1.4 board with the ‘GRBL on Rambo’ firmware. This is attached to a raspberry pi4 running cnc.js.
When I connect through USB, I can send commands and receive msg from the machine just fine. So GRBL and cnc.js are talking. When the initial startup is complete the steppers do not even power on. I can slide the gantries around. If I try to jog I get an error 2 soft limits.
However, when I flash Marlin onto the SKR board and select Marlin in CNC.js everything works fine and I’ve drawn a Crown no problems. So I’m assuming it’s a setting in GRBL somewhere. I disabled Homing Init lock and the safety door lock as well.
Which setting should I look into and where are the stepper drivers defined?
