Movement without Homing

[SnowCrash]

Hi,

I seem to remember reading somewhere about the possibility of manually overriding the precondition of 'homing' for moving the effector.

However, I couldn't find the right command in the Duet's gcode list or the forum.

Could someone please remind me how this could be done?

Thanks!

ps I have a Delta if it makes a difference.

Thanks, @phaedrux

That command does not apply to delta printers. Normal movement on a delta can only be done after homing.

You can do individual motor moves before homing using G1 S2 moves. See the wiki page on configuring RRF for a delta printer.

Thanks for the clarification & pointer, @dc42.

I read the relevant doc and I think I'll use G1 S1 as I'd like the endstops to be sensed and stop the axis movement at the top limit - is this correct?

Also, am I correct in understanding that S1 means 'moving with endstop sensing' and S2 means 'moving without endstop sensing'?

Lastly, as I'm going to use the S parameter, there's no need to use G90 & G91 for this operation, right?

That's all correct, except that you need to put a delta printer into relative mode (G91) before it will accept G1 S1 and G1 S2 moves.

Got it, thanks @dc42!
