Very nice work on those out of print barcrest connectors. on a side note I remember buying a machine circa 1990 from a supplier in Blackpool for £80(I can’t remember what it was but it definitely wasn’t a barcrest)and it had very similar if not the same connectors. It could have been a Gowerpoint but I only had it a short while before I swapped it for a JPM Hot Pot(which I still have to this day).

A thought on the new connector and wiring, as I fitted 1mm 16A cable and with the connector on mine being a tighter fit this should reduce the chance of any overheating or melting of the cable, or pins on the board connector. Time will tell

I suppose all things considered, in 10 or 20 or 30 + years time it's going to need a new type of connector to keep these boards running so you're probably going in the right direction. If any of us will still be about to want to use them of course.

Yes agreed, I’ve used PLA, nylon, ABS, even ASA now I have settled on PTEG now for all of my prints, will be fine and temperature resilient. As the contacts are a tight and the cable is upgraded I don’t expect much heat in the connector.

Cracking work!! Don't forget PLA has a very low melting point so if at anytime the plastic gets warm or warm through pin contacts it could melt, does your printer go high enough to print in nylon?

Fantastic work Ed 😄 you will have a nearly brand new machine by the time you have finished 👍👍👍

Yep, you're going down the same path I went. The original connectors were Combo-line and you could put the crimp connectors (male and female) in the connectors. It doesn't mention the PCB type fitted to MPU3's and I assume it then wasn't called Combo-line. I also suspect that the pins weren't a separate item and the connectors came fully populated. If only I could find a part number for them!! They weren't a Barcrest special though because I've seen these connectors in juke boxes and I think they also appeared in light aircraft way back.
