G-code magic for advanced homing?
-
@bot hold on a sec! This part I already know! Basically if it homed before that my command in homing subroutine go to X10 Y10 works! So perhaps it is unhomed but still knows where is 10,10....
Bit weird though. -
@monster That is very interesting. So it moves to X10 Y10 if homed, and then continues with the script? But it omits the X10 Y10 movement if not homed?
Perhaps, as you say, it's not getting flagged as unhomed right away, and you need to indent the script as @littlehobbyshop says.

@monster did you try replacing those indents with 4 spaces?
Nope:
if !move.axes[0].homed || !move.axes[1].homed || !move.axes[2].homed M300 S300 P200 else M300 S100 P200
This plays (via webui) S100 sound
if !move.axes[0].homed || !move.axes[1].homed || !move.axes[2].homed M300 S300 P200 ;else ; M300 S100 P200
and this plays S300 sound

Not exactly.
If homed before then it goes to 10,10 and then by relative moving goes to 0,0
if not homed then (i believe) it takes that X10 Y10 to move 10mm in opposite direction (away from end swithces) and then by relative moving still gets parked on 0,0 -
@littlehobbyshop is there way to see a value of variable?
display it in message?
or much better would be to display it in log?
something like
"log move.axes[0].homed"
by anychance?

@monster This does beg the question, if an axis is homed, why do you want to home it again? Or am I missing something?

Version:
Board: Duet 3 MB6HC (MB6HC)
DSF Version: 1.2.4.0
Firmware: RepRapFirmware for Duet 3 MB6HC v0.6 or 1.0 3.0 (2020-01-03b3)GCode meta commands are not yet supported by DSF, so for now on Duet 3 they only work in standalone mode. You need one of the RRF 3.01 release candidates to use them, but you are running 3.0. That's also why your m409 command doesn't work.

Well, this is good question ofc
Answers rather "creative"- Let's say I powered printer up, pushed home button.
After that a print would like to re-home it before starting - that is reasonable. - Or I simply ordered heads to move and now want to re-park them
There might be few more ideas why but of course you may say that they are not very needed and can be worked around, that is true.
So I guess best answer I could give is - why not? :)))) Just for sake of exercise on printer control - Let's say I powered printer up, pushed home button.

Is there a good way not to miss actual release?

Yes, go to https://github.com/dc42/RepRapFirmware and click on Watch.
