I am trying to configure my PWNCNC which I brought over from my old machine, I have configured the VFD but I am unable to set the parameters needed in gsender which is mainly:
$395 = MODVFD
$462 = 40960
$463 = 40961
$464 = 36864
I only see the following options in gsender 20260318 (1.6.3), any help will be appreciated. I have searched in pwncnc forums without a solution.

@sylthecru When you say that you are unable to set those parameters, how have you tried to set them? What happens when you try that?
@FranStet I will follow up with the error code when I back home tonight. But off the top of.my head it was the variable is not correct
Per pwncnc documentation $395 = MODVFD which fails

Hey,
The first new firmware release for the EXT (20260318) only had 4 spindles compiled in due to a web builder limitation/engineer oversight.
The newer release since then has all of them available.
You’d need to reflash your board with 20260525, which would give you MODVFD as an option.
This is not a gSender issue, its the firmware build you have on there.
Firmware images for the EXT can be found here: Firmware & Flashing - SuperLongBoard
