I have a 1995 Bridgeport Torq Cut 22 that I have just got up and running in my garage. I am having problems with an alarm stating "spindle not up to speed in time". When I watch the actual RPM I notice that when I start with a spindle speed too fast the spindle speed stated on the screen radically fluctuates all over the place and at times will actually say 0 (zero) when the spindle is obviously going many thousand RPM. A couple seconds after I see the spindle speed on the screed fluctuating and obviously not accurate I get the alarm. Strangely enough if I start the spindle at a very slow RPM, there seems to be no problem. Then as I slowly increase the spindle speed it reaches an RPM where you start to see the RPM fluctuate, the faster the spindle goes the worse the error is. If I gradually ramp up the RPM I can start to see it fluctuate and I just simply wait a little while at that RPM then it evens out, then I can go a little faster until I see it again fluctuate then I again wait for it to level out, etc, etc. It is as if it needs to warm up. Admittedly the garage is quite cold, 40 degrees or so when I start up. Is this an encoder problem. Will these machines/encoders work in a cold climate. Any thoughts would greatly appreciated. Also I'm assuming what measures the actual RPM of the spindle is indeed the encoder??? The little component that has a little gilmer type belt that comes off of the spindle??? Thanks, Mike.

OH CRAP,
And to add to my problems, I just called Bridgeport/Hardinge and the encoder is obsolete and no longer made by the manufacturer! Anyone have any ideas as to where to get one or get mine repaired if this is indeed the problem? Thanks again, Mike.
