CNC post-processor customization
Send your post-processor, your requirements and a couple of programs — get the modified post, a line-by-line explanation of every G-code change and an equivalence report: a simulator compares old and new toolpaths to a thousandth of a millimetre.
- Post-processor adapted to your spec: tool change, R/IJK arcs, drilling cycles, coolant, header, number format
- G-code diff: every changed line tied to a spec item, zero unexplained changes
- Equivalence report: old and new toolpaths match within 0.001 mm
- Automatic safety checks: rapids inside stock, tool change position, spindle and coolant
- We currently work with Python and text-based posts (FreeCAD CAM, LinuxCNC, Mach). Fusion 360 posts (.cps) need a run on your Fusion licence or a licensed partner
- We don't test on your machine: the first dry run is yours
- Thread milling/tapping is checked separately — send a program with threads
Example: audit of the stock FreeCAD → Fanuc post
12 programs, 8 shop-spec edits, 253 thousand toolpath points compared. Along the way we found two dangerous bugs in the stock post:
Tool change forces G54
In multi-part programs (G55, G56…) machining after a tool change went to G54 — the wrong part.
Missing I/J in arcs
Fanuc reads a missing centre coordinate as 0 — the arc deviated from the toolpath by up to 4.27 mm.
FAQ
Where do our files go?
Processing runs on the Claude model (Anthropic, USA). If your drawings can't leave your jurisdiction, tell us first and we'll discuss options.
Who is responsible for the result?
We are responsible for every dimension being checked and every ambiguity being listed. Final acceptance is done by your engineer.
What does it cost?
The pilot and test runs are free for now. We quote a price after the test, once your volumes and part types are clear.
Send your post and 2–3 programs
We adapt it to your machine and explain every changed line before you run a program.
