MK3 -> MK4
Hi. I just saw the release of MK4 and it appears to fix the three main issues I have with my Mk3...
- J5 limit switch mechanism unreliable and creeps over time.
- Encoders have to be disabled as constant false warnings. New version seems to use some protective tape?
- Enclosure bigger and a separate power rail terminal block. Avoid having to squash a bundle of soldered wires under a screw terminal.
I'd love to upgrade my MK3 with these updates, has anyone had a look at how this is possible? Re-doing the wiring will be unpleasant but I think will bring long-term reliability.
Is it possible to remove the robot from the enclosure, feed out all the wires and reconnect it or will I have many issues with wires not reaching?
Many thanks, Alastair

I believe most of the wires should reach. You will need a 2x12 terminal board, (2) Dupont 2.54mm connectors and some EMI tape. These items are easy to source.
