Error 9 after installing y axis roller

After some conversations with Gil (from Ortur) it turns out that their firmware people added some “features” to one of the settings in the machine. Short version, $22=0 to turn off homing, $22=43 to turn it back on (ONLY for the Ortur). Longer version: In GRBL, the homing enable setting ($22) is a boolean, meaning it can be set to 0 (off) or 1 (on). They turned it into a bit-field, meaning it now has other features, so “on” is now 43. bit0 : 1 (homing enabled) bit1 : 2 (??) bit3 : 8 (?…

Also look for the Error 9 - that’s the big tell.
