3HC pins issue (io2.out) (RRF 3.3)

chernogorsky

Hi, I try configuring zprobe on 3hc,
and receive strange behavior
io0.out does not work (no error message, just do not drive servo). may be not related to the case.
io1.out - works like a charm
io2.out - I receive the following error M950: Unknown pin name 'io2.out'

steps to reproduce
connect 3hc with proper number (let's say 10)

than
M950 S0 C"10.io2.out"
M558 P9 C"10.io2.in" I0 R1 H3

m122 b10

Did you enable usage (whether it's present or not) of a PanelDue? If so, the firmware assumes that it's connected to io0.

If you want more detailed answers, please provide your config.g file, pasted in using the </> tag above the Reply window.

Can you post your full config.g and the results of M122 for your mainboard as well?

BLtouch i assume?

Only PWM-capable ports support servos. See https://duet3d.dozuki.com/Wiki/Duet_3_Expansion_Hardware_Overview#Section_IO for which ports are PWM-capable.

Thanks, I miss that part from the documentation.
So, all goes as expected than

Except for the unknown pin message.
