I have brought this up prior with no response. I have a printer with a Z axis that has an extruder and slide mechanics that make it heavy enough that if stepper is not enabled after power up, axis will overhaul the leadscrew and drop. I have a 24VDC brake attached so that the slide doesn't drop when printer is powered down, however this releases upon power up. Obviously if I home immediately, the enable comes on and holds the slide but I don't always do this right away. I need a a way to enable the Z axis drive after power up before I make a move or homing, something like the M17 command for Marlin, however M17 is not implemented for Repetier. Is there a way to accomplish in firmware?
