Much appreciated. Thank you. When I'm done I'll post a few pictures

Just as a side note: I watched again a nice video where a guy have made the controller like a pendant. As i said in comments of video, i wish i have come up earlier with that idea. Now i have to go back and forth on my big machine, instead of taking the pendant with me.

Been working on this for a few months now. Trying to find a nice way to mount the controller. Didn't come up to bad albeit with a few mods to the PC case.
There's one more power supply to go in for the spindle motor.

Once that's done i'll be up and running :)

Not bad. Very nice!

What drives are that? Do you have cooler in front of enclosure near them ? Or just the enclosure other coolers?

Thanks Boyan,
The drivers are just generic Chinese brand set to half step.
At the moment i only have one fan at the rear blowing in... i will replace this with a bigger fan soon and would like to use some smaller ones near the drivers. This is still a work in progress.

Hi there, im currently designing my own CNC Router, i had planned to use this controller. On my longest /Axis (X Axis here in the UK) i have Dual Ballscrews and 4nm Nema23's, i see it has already been mentioned that the controller cannot provide individual homing for each screw (by utilizing the A Axis). I see there are examples of the controller providing signal to each of the drivers, im just wondering if i am likely to encounter any problems with the gantry running out of tram using this method? I plan to use the AM882 drivers.

Thanks

Alex

Provided you don't crash the machine and cause one axis to stall and twist the gantry, then it's not likely to be a problem. You just need to ensure you have some method to re-align the gantry if you do. If it was me, I'd probably just setup some accurate endstops at one end, and slowly run the gantry into them to square it up again. Then re-home it to regain position.
