Despite UPS couriers best efforts to muck up my delivery, the parts were dropped off at a collection point Yesterday... UPS just didn't bother telling me...
I refitted the new parts and my printer is back in service
the wires on the left are the standard Prusa power cables, they have a higher than average conductor count (approximately 22 individual strands in the bundle rather than 7 in a less flexible cable) I would rather use wires like on the right, these are flexible silicone rubber insulated wires, with 252 individual conductors and a current rating of 22Amps, which should be adequate for the job
this is what happenned to my heatbed! caused by flexing of the cable loom, and stiffness of the power cables
the replacement parts included a replacement heat bed, with revised cable grip, to reduce cable flexing at the heatbed connections.
I try to make suggestions that I believe to be well founded and safe,You should understand the context and ensure you are happy that they are safe before attempting to apply my suggestions,
what you do, is YOUR responsibility.
