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

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 :)

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.

Bob

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

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".
