Hi guys, I'm new to the forum, I have a Tormach PCNC 1100 machine. While working, that is, while cutting, the spindle rotation speed drops by one or two steps by itself. Does anyone have any information on the subject, why it could be? I would be very glad if you could help. Thanks, take it easy.

Re: Tormach PCNC 1100 machine spindle rotation speed drop
"the spindle rotation speed drops by one or two steps by itself"
Are you saying that the spindle speed display shows a lower RPM than what is commanded?
Or are you saying that the "speed override" slider on the screen moves left without you touching it?
Or do you mean something else?
How much is "a step"?
How heavy a cut are you taking?
Does it recover when you stop the program?
I think we'll need a little more detail about which specific speed you're looking at, and how exactly it's changing in a way you expected it not to.
