Hi
I would like to have a moderated sticky post where all suggested configurations are placed in the first message. We have the https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_CNC but it is not really updated and does not mentions configurations that needs to be done for a working CNC.

None trivial things I have noticed that needs to be configured for a Cartesian CNC in Duet Wifi firmware 3.4.6:

M203 RRF has a default minimum movement speed of 0.5mm/sec. This is way to high. I crashed my CNC while trying to drill a hole. Very BAD. A warning should appear in the DWC when it replaces speeds lower than 0.5mm/s for 0.5mm/s.
M350 Interpolation should not be used. The lowest speed limit for Interpolation to always work good is to high for my CNC it created wobbly lines while turning a cone.
M669 Segmentation is good to have if you need to stop the motion in a predictable manner.

Looking forward to learn more things that should be configured.

Thanks

@hurzhurz I want to thank you for the fantastic work you have done.

I started looking for a pendant solution for my CNC roughly a week ago and today I finished the build. Almost plug and play with the instructions you provided. Amazing to have a wireless pendant. Still surprises me that it works.

Only thing I had to figure out was where to put the macro folder. It should be in the systems directory and not the macros.

Total cost was 200€ for the six channel pendant and some spare raspberry picos, Panel USB and such. It worked first try and no smoke was produced during the build.

I’m truly grateful ️
