Looking at https://d17kynu4zpq5hy.cloudfront.net/igi/duet3d/4k56ZjaaAHrTJI6Z.huge
... where exactly did you plug in the two wires coming from the endstop switches?

As far as I can tell you your bed.g is missing a G30 command with the appropriate S-Parameter to perform the desired calibration calculation.
See https://duet3d.dozuki.com/Wiki/Gcode#Section_G30_Single_Z_Probe and https://duet3d.dozuki.com/Wiki/Setting_up_automatic_probing_of_the_print_bed.

Also, you may need to include a M501 command a the end of your config.g to enable execution of config-override.g.

@mihaitintea said in Delta X,Y,Z towers anomalies:

Try to move X down 10 m, but this happens: X goes up about 5 mm, Y goes down 5 mm, Z does not move.
repeat the Home All procedure
Try to move Y down 10 mm, but this happens: X goes down 5 mm, Y goes up 5 mm, Z does not move
repeat the Home All procedure
Try to move Z down 25 mm, but this happens: X and Y and Z, all move down at the same time 25 mm.

The X/Y/Z controls in the machine control section refer to build space coordinates, not to the towers themselves.

So it is nothing but expected that issuing "Z down 25mm" will of course result in all carriages moving down by 25mm.
Same goes for movements in X and Y directions - the all are combinations of moving the three tower carriages of the delta printer.

Why would you need to move a single carriage (except for testing purposes, which can be achieved by G1 S2 commands - see https://duet3d.dozuki.com/Wiki/Test_axes_or_motors_individually)

@goodchrhere I'm glad you got it working!
To have Z axis behaving as X and Y you should just remove the lines

M574 Z1 S3 ; set endstops controlled by motor stall detection

; Z-Probe
M574 Z1 S2 ; set endstops controlled by probe

from config.g

Seems to me like you're hitting the limits of the printable area.
Is this a brim you're printing around your object?
Or does this extended area belong to the model itself?
If it's a brim you might try printing without ...

Also, 134x94mm should be around 163.7mm diagonally

@sethipus A curved wipe which is following the circular bed outline will of course require less build plate space than a straight line, which may cut off a relatively large portion of the circular bed.

Just as a quick feedback: I can confirm that running 4 Duet Magnetic Filament Monitors on common wires for +3.3V and GND coming from E0stop on a Duet2 Wifi does indeed work like a charm.

Thanks again and Happy Easter everyone!

The calibration data is just an averaging measurement over the duration of a print job, and gives you a rough frame for configuring the upper and lower ends of your filament sensor's sensitivity.
So nothing to store directly, just some input for you to perfect your printer's setup, especially the values for the M591 command in config.g

Just a guess into the blue: what does the file /sys/config-override.g on the Duet SD card contain?

@dc42 @T3P3Tony
The replacement filament monitor arrived today - thanks for the really fast and painless swap!

Just installed, gave it a quick go ...

• no more "Sensor not working" messages
• M591 D0 reports quite usable data
  • Duet3D rotating magnet filament monitor v2 on input 3, disabled, sensitivity 25.33mm/rev, allow 85% to 115%, check every 3.0mm, current pos 14.8, measured sensitivity 25.21mm/rev, min 90% max 110% over 1252.5mm
• M122reports no frame errors anymore
  • Extruder 0: pos 14.77, ok, measured sens 25.21mm/rev min 90% max 110% over 1252.5mm, errs: frame 0 parity 0 ovrun 0 pol 1 ovdue 0

Will do some more tests in the coming days, but those are by far the best results I was ever able to get!

Thanks to both the teams of Filastruder and Duet3D for your great support!
Much appreciated!

As far as I know babystepping changes Z=0 datum, but leaves the current Z of the active Tool untouched.
If baby stepping would change both values you would not be able to change the relative distance between nozzle and bed.
