Hi,
Have a Bridgeport VMC412 with TNC2500 control.
When we bought the machine pre-owned some 18 years ago it gave me aTNC operating temperature exceeded and the monitor goes Phoosssshhhhh and lot of numbers flashing.
We made a hole at the bottom and fitted a small extractor and a hole on the side with a car filter fitted and the machine has worked for years trouble free.
Now we are machining a large complex part which takes 30 hours straight and the machine is doing the same. I fitted a stand fan blowing over the cabinet and it works ok but this is risky.
I know there should be a thermistor somewhere which monitors the temperature. The temperature inside is very low as it is winter as well.
I also know that there is a parameter in the machine which controls this. I wish to look at this as well.
Could somebody identify where this thermistor might be?
Somebody some years ago had this problem and somebody suggested a dangerous solution according to my tech
help please! everytime this happens the workpiece is bust.
