Thank you for your response. I did this: I changed the whole machine FCM and the FCM II, as you write me everything changed. Programmed new EPROM, etc. FCM machine and it works perfectly as FCM II. Only now I've changed the option to push mechanicall

Sorry, I guess I missed the point originally but yes, in the case of separate drawings and BOMs, the drawing wouldn't have to change unless the form or fit changed enough to justify a change. Obviously if the only BOM is the one on the drawing, the

We do not know how your KIC2000 calculates slope. Here's an approach to calculating slope: * Subtract the lower temperature from the upper temperature. [Temp|upper-Temp|lower] = Temp|change * Subtract the time when the lower temperature was measured
