Bed.g repeated execution based on deviation results

MikeS

Hi everyone!
Finally i switched from my old wooden delta to a more solid printer (aka Voron 2.4). Right now it's working great with duet2 wifi + duex 5!
Actually i'm doing the bed auto leveling (4 points with a motor for each point) with the current code in bed.g :

M561

G30 P0 X50 Y50 Z-99999
G30 P1 X50 Y300 Z-99999 
G30 P2 X300 Y300 Z-99999
G30 P3 X300 Y50 Z-99999 S4

Is it possible to repeat this procedure till deviation reaches a desider threshold? Usually i get 0.010 or less in 2 to 4 cycle...i would like to automate the manual process of calling bed.g manually.

Thanks!

@MikeS
You can place the whole thing in a "while" loop
There are numerous examples.

be aware that conditional code need rrf3

Thank you for the suggestion. I did it quickly but right now is acting a little strange... i'll check the documentation better tomorrow and post the macro when it's finished.

Ok here it is my result files after some experiments:

bed.g

echo "---GANTRY LEVELING PROCEDURE---"
echo "Old deviation was: " ^ move.calibration.initial.deviation
M561
echo "Bed transformation cleared."
if !move.axes[0].homed || !move.axes[1].homed
  echo "Printer was not homed. Homing now."
  G28
echo "Doing 1st pass"
M98 P"gantry_level.g"
while move.calibration.initial.deviation > 0.01
  echo "Current deviation: " ^ move.calibration.initial.deviation
  echo "Deviation over threshold. Executing another pass."
  M98 P"gantry_level.g"
  continue
echo "Leveling complete. Current deviation: " ^ move.calibration.initial.deviation
echo "Homing printer to get true z height."
G28

gantry_level.g

G30 P0 X50 Y75 Z-99999
G30 P1 X50 Y325 Z-99999
G30 P2 X300 Y325 Z-99999
G30 P3 X300 Y75 Z-99999 S4

I didn't find a way to stop RRF to log to console the leveling data. Is it possible to hide it at start and then enable it at the end of the code?
Here's an example of what i would like to get rid off:

Thanks

There is currently no means to suppress console output.

@dc42 Thanks David this isn't a huge problem, only an aesthetic one. Also thanks on the development roadmap for RRF! I can't wait to try a future input shaper implementation!
