RE: [CAD_CAM_EDM_DRO] CNC Control

Not knowing TurboCnc - but I presume you can set a function key or select a
key to advance the router ?

Heath Robinson method - a small micro switch on the rotating work which
fires a solenoid to press the 'advance' button on your keyboard every time
the work turns 1 rev.

More elegant - some electronics knowledge required - interface the micro
switch to a PIC in series
with the keyboard input on the PC - The PIC would then send the required key
code to he software every time the micro switch closes.

Hope this helps

Subject: [CAD_CAM_EDM_DRO] CNC Control


I am in the process of setting up a 2-axis cnc router wood lathe and would
like to use Turbocnc as
the control software. The first axis is already set-up and running. It
moves the router in and out
of the part. The rotating wood to be turned is very heavy. I am using a 1/4
hp DC gearmotor, with a
speed controller to set the rpm. It needs to turn at about 10 rpm or it
will start to burn.

My question is, how can I have the router advance at each revolution? How
would an encoder on the lathe shaft
be set-up to advance the router per revolution of the shaft with turbocnc?

Thank you for your help.
Bruce
