You might need to turn the tool table on in the machine parameters via the mod button.
I had to. My parameter might be different because I have a tnc 360.
When you set a tool use the position capture button. the one with a little dot in the center with arrows around it. Or you can do this.
set your z datum first.. (set the longest tool to zero)
touch off the longest tool to the top off the part and hit z button then zero.
then touch off another tool.. look at the display and the z value will be a negative number. write that number down. enter that number directly in your program. With a tool def and length value.
I program my machine in iso not conversational. So i am not sure what the line of code should look like. But i hope you get the idea.
Hit the mod button
enter code 95148 to access parameters
go to MP7260 it is probably set to Zero
if set to 0 no tool table
up to 99 tools
(set it to 99 and the tool table will be program zero)
REMEBER THIS IS FOR A TNC-360 USE CAUTION. Look at the parameter first then edit
