Sherline Rotary Table NC control
« on: April 10, 2011, 05:52:01 AM »
Hi,

I live in New Zealand and am new to the Forum. I have a Taig CNC mill to which I have just added a Sherline rotary table. It is all hooked up and running fine, set up for A axis operation. My question is; can Mach3 continuously rotate the rotary table?

Thanks in advance,
Ken.

If you are trying to use it as a spindle then no not really. There may be ways to accomplish this but nothing as simple as just commanding an A axis continuous rotation.

In addition to what Hood posted, you will want to use a servo and not a stepper for turning it continously.

Not sure why you would want to but, if you set up your A axis as a spindle then you could. You would have to turn on spindle with M03 or M04 with a speed command. You may only get 4 or 5 rpm out of it though. This would be hard on the table over time. On the other hand, you could command the A axis for a position in multiples of 360. Say you wanted to rotate twice. The command "G01 A 720 F 500" even with the rollover it should rotate twice around.
