Hello. Can anyone help me to find out the home position code for a cnc lathe with Fanuc control 0i-TF.
when i put G28 U0.0 W0.0, the tool moves towards the chuck and the x and z values are zero here. But if i use G30 U0.0 W0.0 the tool moves away to a home position but the values of x and z are not showing zero. My question is does htis control need a home position code or else the parameters are not correct.
Please let me have your opinions.
Thanks
Hi,
Don't use G30, better is G53 G00 X0. - G53 G00 Z0. if the G28 doesn't work.

It is possible that zero has been set to be the center of the chuck. (Which you probably can never get to) Check parameter 1240 if it has a value in it then they are offsetting your machine zero position. Also check parameter 1815 and if APC & APZ are set then homing isn’t necessary.
Change G30 point
1. CNC Mode
2. Press MDI
3. Press offset button until Setting handy and parameter write menu appers
4. Write 1 on Parameter Write then input
5. Press System until serch parameter is popping up
6. Write 1241 ( OBS Dont press INPUT after writing 1241) press No search on screen
7. Write your value in the cells and press input.
8. Go back and change parameter write to 0
9. Done.
