Can I buy the board?
Currently I have tinyg v8, but I need to add 4th axis to my double Y CNC mill.
I could not get the tinyg to work with external drivers (m542t and KL5056).
I have tried level shifters and could not make it work. My DIY CNC is 40″x60″. I used 0.5″ aluminum plates for most of the gantry and 60mmx90mm extrusions for the frame (everything is over 300LB).
2.8A from tinyg seems to work with 425oz steppers (some active cooling) but I need 5th motor or connect two motors in parallel on bigger external driver (KL5056 has 5.6A)
I’d like to add 4th axis along Y axis so I could work on pieces 48″ long.
