    I've just fitted the (preassembled) Prusa i3 titan kit to my BQ Hephestos i3.

    I've fitted it and belted it.

    The ONLY motor i've touched is the extruder motor - but now my X Axis is reversed ??

    Help!!!

    Thinking about it – I guess It’s as simple as the fact the carriage is now mounted on the front of the axis rods rather than behind – so my question becomes – how do I reverse the direction of the x axis motor simply and quickly ??

    Usually you just need to reverse the plug connected to the motherboard or on the motor if that is available.

    That's exactly what I did. I got the upgrade kit with motor and it ran backwards at first, so I just unplugged it from the RAMPS board and turned the plug the other way. Works perfectly.

    I was being dense. I worked it out later last night.

    On the BQ Hephestos the X Carriage is mounted behind the rods rather than in front. Therefore monting the carriage in front results in reversed x axis.

    When you go into the firmware there's an 'invert_xaxis' setting - which was set to true - I set it to false and bingo.

    I haven't actually got to extuding yet lol

    :D I can only say it was worth it on my Prusa i3 - the quality of the prints I get has improved, and loading new filament is much nicer.
