that's ancient and deprecated

if you don't insist on AVR I use this: https://github.com/grblHAL/

Limiting what you can get out of a better or larger CNC device by using GRBL is DUMB!

sure, but we were talking a 6040, not some big industrial machine with servos, tool changers, etc.

beanflying:
Nowhere have I said it isn't an option but there is better around which for some reason you insist on arguing against any possibility that other options exist and should be considered :-//

GRBL is simply a technically inferior option with worse garbled support for little to zero $ saved over a LinuxCNC solution. This is a simple and basic truth.

It is not your place to 'limit' others in where they can take a 6040 Router. They are not limited to basic steppers or no tool changer and there is plenty around who have tinkered way more than the base platform warrants. There is also plenty of exceptionally well made similar sized machines now available so basing the controller for X size so use Y platform is also not sensible.

Starting with a restriction on moving forward because you saved a few $ and went with a worse option for a controller remains a Dumb choice.

So which boards would you use then? Post some suggestions.
OP will still need: stepper driver, VFD, power supply, etc. Which should be similar regardless of GRBL or LinuxCNC

DDCS appears to be $300 on its own? https://www.aliexpress.com/item/4000562938720.html
I like the idea but, it locks you in to only the features they've implemented.

2 computers, One Win 7 (very old laptop and very slow} One laptop (fast) with Linux
Would prefer either LAN/USB or stand alone system.
Like the OpenBuilds BlackBox Motion Control System but can not get past the "Spam Check" part of their web site so I have been looking for another company that stocks this item. No luck so may have to explore other options.
Thanks

Not specified by the OP, only said 'controller' is dead so until told differently Steppers and VFD are likely ok in the old box. Also opening a can of worms on Steppers open or closed loop and Servos it definitely worth another thread even then.

With the DDCS Expert it has a bunch more functionality over the earlier (and still good) 3.1 you linked http://www.ddcnc.com/?m=home&c=View&a=index&aid=154&lang=en I am still looking at it as it represents a good chunk of change. Getting good quality information on it is fairly much limited to a farcebook group but they seem to be getting a fair bit out of them. Manufacturer support - not a lot.

Currently I have an older Planet
CNC Board on it but the software is a bit clunky and is behind what I would like to see in features and a path moving forward. It just needs to go but it does work.

LinuxCNC as I stated earlier is not 'at this stage' on my list as adding Linux (not mentioning the war do that elsewhere there is a thread) is not for me without a very real need and no alternative. But for someone who effectively only has a Linux box sure why not it works well by most accounts.

Mach3 and or 4 are the Elephants in the room and there is any number of Boards good and Bad but I am not 100% sold on the software either. Mach3 unless you already have hardware really should be avoided IMO for a new build.

I have had a bit of a look at the Acorn offering but it is really expensive by the time I get it to this side of the world with some features and extra bits. Still on the shortlist at this stage. https://www.centroidcnc.com/centroid_diy/acorn_cnc_controller.html
