Variaxis j500 using eia

We are new to using G-code on a mazak and are having trouble with a few things. We program it with Fusion 360. Our problem is understanding the tool length offset. Fusion outputs a g43.4 but gives us an error while trying to rotate the A axis. We really have no understanding of the G43.4 or the dynamic offset built on the machine and can't seem to find any info about it.

Any help would be great.

G43.4 is for tool tip control for simultaneous 5 axis machining. Are you moving all 5 axes at once? Most Variaxis J machines are not full 5 axis, they are 4+1. You can use G43.4 as long as you don't have XYZAC together on one line.

What's the alarm you're getting?

Optional point tool tip not provided. We aren't trying to use 5 axis - it won't do it. We are cutting a slot radially around the OD of a part. We want the A axis to rotate to cut the slot. The spindle came on then the error came up.

Sounds like you don't have the option on your machine. You'll have to fix the post to not use G43.4. Most likely you will have to program in G93 inverse time to accomplish this.

I'm not 100% sure it's even possible to contour with the A-axis on that machine, it might be positioning only. Is this a new machine?
