Also you would typically configure P2 if you only have one breakout board
as that has the first stepgens and pwmgens,

Here's firmware that places the first stepgens and PWMgen on P1:

(basically just reverses the connectors)  You would need to use
pncconfs "Discover" option to get it to display the correct
GPIO and channel numbers.

Replied by PCW on topic Using 7c81 with 5v encoder on bob3 config
A 1.8V low level is not valid for a 5V single ended encoder output
Maximum low level for TTL signals is 0.8V

This may be a wiring error or similar.

Stepgens for 2-9 for axes. Where is two? Where is 10 thru 14?

Yes, the config will work, but features might not.
You have to choose stepgens or PWMgens or encoders that you want to use, also pins for IO if needed.

So you are saying that if everything on the config page says "unused", it will still work?

Remove the dots after the 0 for I and D.
From video, definitely something wrong, but no idea what, that is not normal oscillation as it is moving way to much back and forth.
Do some plots using halscope for command and f-error

Yeah i forgot to mention the size is 640X640X1600mm and print size is 460X460X1200mm, could have pushed the height to 1350mm but if i add a lid it would not leave space for the filament roll.
I will probably start another one, but this time more wide and less height...and a styro cutter...and an EDM...and the mill... As Pink Floyd once said: Time...

As suggested ,have linked pin to my 7c81 input. Its a single phase encoder. I have set the counter mode to 1. But the values are coming between 1.8v and 5v on my meter. The rawcounts are changing to 1 and then 0. Please help as the encoder is not reading any counts and not changing at all.

Sorry for the late reply, that image should also work for de OPI5 plus if you only edit in "armbianEnv.txt" the line:
fdtfile=rockchip/rk3588s-orangepi-5.dtb
to:
fdtfile=rockchip/rk3588-orangepi-5-plus.dtb

At no time did it hit -20°C here, at -10°C it was plenty cold enough for me. It has gotten warmer the last days. The next update on the machine will be very soon (at least I hope).

Also worth remembering that I downloaded the previous latest version 2.9.7 which is also on Debian 13, burned the iso to a pen drive (all be it a different pen drive) using the same version of Rufus with all the same settings and that installed GRUB perfectly
