The other lines are, the stepper, fans and the 230volt heater bands. BUT these are all turned off while I was testing. It would be surprising if this causes EMI. I also did a test while unplugging the fans and plugging them in, but that didn't give any changes, so I think EMI is out of the question.

The voltage drop is something I will check out tomorrow, that will clear up a lot I think.

Thanks!

so... i was going to swap the pt1000 wiring and touched the connector and suddenly it popped back to around the same temp as the rest... guess it was still a sort of loose wire...

thanks anyway
