Dear Community,
I have a Felix Pro (and a Felix 3.0) that were used for Printer Prototyping and the z-sensors are absent/not functional. I am trying to make this machine working as a simple x-y-z machine but since the z-sensors do not work and the printer requires accepted coordinates to move I cannot use it. If the machine would accept G92 commands from repetierhost it would work however it seems that repetierhost does not support this command. I figured that a Felix FDM Printer in the lab takes the initial positions as zero, if I could set this at the prototype it would be sufficient to solve this problem. Does anyone has an idea how I can do this? I think trying to copy the firmware and eeprom from the FDM and upload it on the prototype might work (no idea how I could do this though), but it would be a rather risky endeavour since the prototype has some eeprom/firmware changes applied to it that might be necessary to use it. 
Kind regards,

    in manual commands host assumes zou are homed and at set home position. Best is if zou disable at z 0 position. On the other side at least my y axis moves down easyly when unpowered. At least for the pro did you try activating second extruder and home? I think each extruder has a own z switch.
