Hi william
Good luck with the project . Mine is working well (on Mach 3 ) but by all means stick around as I am migrating to Linux cnc .
Would be good to see your progress too if you could open a thread. Mine was essentially complete although I could not get the Boxford boards working.

My belts are 6x400 and 6 x600 (optibelt ) https://simplybearings.co.uk/shop/pr...4&vat_inc=true
