![]() To self square, both limit switches on the cloned axis must be physically positioned to trigger when the gantry is square. This requires an additional limit switch for the cloned motor. This optional dual axis feature is primarily for the homing cycle to locate two sides of a dual-motor gantry independently, i.e. These pins replace the spindle direction and optional coolant mist pins. The independent direction pin is not absolutely necessary but facilitates easy direction inverting with a Grbl $$ setting. Uno Digital 13 = Coolant (replacing spindle direction.)Īfter installing the grbl repository as a library in Arduino, uncomment out the following lines in config.h file in the grbl library folder.ĭual axis feature requires an independent step pulse pin to operate.
