The illusive Boxford 260vmc

[i2i]

there is the old "burst the bubble" way to look at this. Why do you need a spindle tacho on the machine, when it shows you on the monitor what speed the spindle is doing. But most of all, you should know what speed it's going as you would have written the code.

Well as i have said having a the ability to axis jog without using the PC appeals to me and having a nice RED led display of the speed of the spindle i think is a nice feature, and the other features that irving has mentioned is just a bonus. Besides which i like buttons so there :heehee:

Ahh yes but there is the speed mach is telling the motor it should be doing and there is the actual speed at the spindle which is what i am after for reference..

IE, belt snaps Mach says 2000rpm, actual spindle at tool 0 rpm.

You're still thinking manual, you've got to get on the cnc bandwagon and trust the machine.
