A while ago, I created some simple command buttons in Octoprint to help with bed levelling, by hopping to particular points on the bed. I realised that what I actually want to do is move Z up 10mm, move, and then home Z though, to avoid ploughing the nozzle along the bed if the level is badly off.
So I did this:
- commands: - G91 - G1 Z-10 - G90 - G1 X30 Y160 F9000 - G28 Z name: Back Left type: command
Which should be, switch to relative move, Move -10mm Z, switch back to absolute, go to the specified point and then home Z.
Except there's no Z move. I get the feeling that something might be optimising the moves together into one, or something similar... how can I get my printer to move up, then across, then down?
(printer is an quite modified Anet A8 i3 clone - I think the board is Melzi-based?)
