Hi everybody i have a problem and need some help i just bought my machine about two weeks ago i also bought the bits and the probe. when i unpacked it there was no quick change bit holder but had a bit holder that you use an allen wrench i emailed and questioned it and was told that mine was the newer version and that i didn't need the quick bit changer tool so i said ok now everything that i read in the manual seems to refer to the quick bit changer and the tool anyway i tried to hook up the probe and there is no plug in on the c version machine that i bought so does this have anything to do with the quick bit changer and why would they send me the probe if it doesn't work with this machine or let me know before i bought the probe.
