Mark, in your opinion, is the BB-X32 a good fit for this machine? I saw the one build with the Laguna 4x4, which would be a similar build, but never got a response from the author. FYI, I do like the BB-X32 and it was a very good choice to get my Onefinity back running.
"I will be using Nema 23 motors" I see no reason why it would not work for your retro fit. The HT Nema 23 have plenty of power and on a screw driven machine its unstoppable.
I am gonna go this rout for the 1st one and see how I like it. At the same time start to put together a closed loop system for the second machine. The second machine has some issues with the X lead screw. I may also look into a ball screw installation vs another lead screw and anti-backlash nut. I am also exploring a rotating nut as an upgrade.
These are the switches currently on the machines ( Aleph PS-7711) . On at both ends of each axis. Can these be used with the BB X32?
