      How do we define the max speed when printing? I use slic3r which unfortunate doesn't allow you to set the Z speed and as a result, it moves far too fast on z hop moves.

          @dragonn I already have it in there, but it's set too 200mm/s (nice speed for homing), I don't want to print at that speed though.

            Then just put M203 Z12000 into homing files end at the end restore it to a lower value at the end of hooming.
            BTW 200mm/s on a z-axis??? This sounds wrong all the way, unless you z-axis is belt driven.

              @dragonn That could be the answer, thanks! It's a belt driven delta yes

                Z hop moves are short, so it won't get up to anything like full speed because of the acceleration limit. What makes you think that the Z hop is too fast?

                On my delta I normally use 0.3mm of Z hop, with the Z speed configured at 250mm/sec and acceleration 2000mm/sec^2.
