Basic tool use
« on: January 13, 2007, 09:09:16 AM »
Hello Everyone,

I am just getting started with CNC and could use some help.  I am using TurboCadCam to generate G-code to feed Mach3 which will drive my ShopTask mill/lathe.  At this point the hardware is working and I have my motors reasonably close.  Now that I can move the table about in a predictable pattern and speed it is almost time to start cutting something.

I am having some difficulty with the Mach3 tool configuration.

I opened the Config | ToolTable dialog and saved tool 1 as:
      Description:     End Mill, 2 flute
      Diameter:        0.2500
      Height:           0.5000

But I haven't been able to figure out how to load tool 1 or tell Mach3 that tool 1 is loaded.  That is to say the Mach3 tool displays are always zero.

What have I missed?

Bob to use tool length offsets you will need to have a G43 H1

This will load tool offset 1 and if you would like more info a good start is the Mach3 manual. and ifyou have more questions please feel free :)
Fixing problems one post at a time ;)

Hello Brian,

I tried entering G43 H1 on the MDI screen, but the  only thing that changed was the Z axis.

What I am looking for is the process that changes the default Tool number zero with a diameter and height of zero to my preferred selection of tool 1 with a diameter of 0.25.

If you of anyone else can point me to where this is addressed in the users manual, I would be very grateful.

Enter G43 T1 H1 M6 in mdi and that should do it.

America gave us powered flight, England the steam train and Germany the car.  Who invented the first boat?

Hi Graham,

Thank you!  That was the key I was looking for...

For those who may follow...

The T (tool) command is described in section 10.10.3 of the "Using Mach3 Mill" manual.
Search for "Select Tool".

Bob  :) :) :)
