Fusion Post Processor Troubleshooting: Find the Cause, Fast
Machine alarm on the first line? Rotary axis spinning the long way? Arcs rejected or holes in the wrong place? We diagnose Fusion post and G-code problems quickly and tell you whether the fix belongs in the post, the CAM setup or the machine.
Is it the post, the CAM or the machine?
When a Fusion program fails at the machine, the cause is not always the post. It can be a CAM setting such as the wrong WCS or tool orientation, a machine configuration mismatch, a controller parameter or option that is not enabled, or genuinely incorrect post logic. Guessing wastes machine time and can lead to the wrong fix.
ENGIMANDI troubleshoots systematically. We review the alarm and NC code, the Fusion setup and operation parameters, the post properties and machine configuration, then reproduce the problem and trace it through the post. You get a clear explanation of the root cause and a fix, whether that is a post change, a CAM setting or a note for the machine builder.
Common symptoms are covered in causes of incorrect G-code from CAM post processors and CNC post processor debugging.

Problems we troubleshoot
The most common Fusion post issues.
Machine Alarms
Illegal codes, format errors, missing options and modal conflicts.
Rotary Problems
Wrong direction, unwinding, wrong angles or missing clamp codes.
Arc Errors
Radius tolerance alarms, wrong planes and helical output problems.
Position Errors
Wrong WCS, offsets, length compensation or retract heights.
Cycle Faults
Tapping, peck and boring cycles behaving differently from the simulation.
Post Errors
Posting failures, script errors and unsupported operation messages in Fusion.
Troubleshooting tools
How we investigate.
Helps us fix it faster
- The .cps post file you used
- The posted NC program
- The Fusion file or an archive of the setup
- Alarm number, text and failing line
- Machine model and controller version
- A known-good program if available

Gather
Post, program, setup and alarm.
Reproduce
Problem recreated in our environment.
Trace
Root cause found in post, CAM or machine.
Fix
Correction and regression check.
Confirm
Verified on the machine with you.
Troubleshooting questions
How quickly can you look at a problem?
Urgent problems are usually reviewed within one working day, often the same day.
What if the problem is not in the post?
We explain the real cause, such as a CAM setting or machine parameter, and how to fix it.
Can you fix posts from other providers?
Yes. We troubleshoot library posts, reseller posts and posts written in-house.
Do we pay if you cannot find the issue?
We agree scope before starting. Most issues are found quickly with the right files.
Can you help prevent future problems?
Yes. Our testing and validation service builds a test suite for your posts.
