Smart Effector on Duet Wifi with RepRapFirmware 3

dgrat

I build a new Delta and tried out the new firmware.
It seems the z_probe_mod pin does not work with this configuration:

If the only thing you have connected to the zprobe header is the smart effector, I think your config should look more like this:

M558 P8 R0.4 C"zprobe.in+zprobe.mod" H5 F300

Note that you don' t need or want a M950 for the zprobe stuff.

this works for me


; Endstops
M574 X2 Y2 Z2 S1 ; Define active high microswitches
M558 P5 C"^zprobe.in" X0 Y0 Z0 H5 R0.4 F1200 T6000 ; Set Z probe type to unmodulated, the axes for which it is used and the probe + travel speeds
G31  P100 X0 Y0 Z-0.05; Set Z probe trigger value, offset and trigger height
M557 R160 S20 ; Define mesh grid

If you ever want to program the sensitivity of the Smart Effector, you will need to use C"zprobe.in+zprobe.mod" in the M558 command. The ^ isn't needed because the Smart Effector drives its output pin both high and low, but does no harm.

@dc42 David that's good to know (I have never had to adjust the smart effector the defaults work fine for me).

zprobe.in+zprobe.mod works fine. I must have missed that in the docu. I usually use the effector with the sensitivity 8:247 and double tip each point.
I get the best consistency with this setting. Down site is that the fans must be off during calibration. In the new firmware a lot of stuff changed. Took me a while to move settings. Good thing is that you have to do it just once.
