Hi all,
So we have had our injection moulder made, with the help of a local blacksmith who fabricated the frame.
She followed Dave’s design pretty closely, except used extruded tube rather than rolled for the barrel, as the latter is a lot more expensive. She then filed out the burr on the inside…
I’ve been doing the electrics today, so we haven’t had a chance to use it yet.
We bought two (Berne) Rex C-100 PID temp controllers off ebay, and whilst I have managed to wire them up to everything ok, they aren’t registering the measured value (PV) and are heating up regardless of the set value (SV).
Has anyone had issues with this? I have read up on the settings and changing various parameters, but this seems to be a more basic issue that makes me think they may be faulty.
One PID reads 999º as its PV and the other hovers around 20-22ª, but this doesn’t change when the SV is altered and a probe placed within a band heater that’s clearly on.
Any ideas most appreciated!
Also, if anyone would like any help with metal fabrication in SE London, I’m sure our smith would like the work and I can put you in touch.
Bertie and Paula
