AI-powered fixes grounded in your machine's actual documentation. From $49 per fix or subscribe from $99/month.

How It Works

Three steps. No contracts.

01

Upload your post-processor

Drop your .pst, .cps, or .bcpst file and describe what's going wrong. Coolant codes misfiring, tool change errors, arc output issues — whatever it is, tell us.

02

AI analyzes with real docs

We pull actual control documentation for your specific machine — not guesswork. The fix is grounded in how your controller actually works, command by command.

03

Get your fix, verify & run

Receive a clear diff view showing exactly what changed and why. Verify on your machine. If something's off, we iterate until it runs clean.

Why cncpostfix.ai

Not a chatbot. Not a guess.

Tired of paying your CAM support provider $2,000–$4,000 a year to take weeks to modify your posts? Or wasting hours going back and forth with a generic AI that's "trying" to fix your issue — without ever having read your machine's manual?

cncpostfix.ai uses RAG (Retrieval-Augmented Generation) — we pull your machine's actual control documentation and feed it directly into the fix. Every output is grounded in verified source material for your specific controller. Not training data. Not a guess.

Generic AI Chatbot / CAM Support
cncpostfix.ai
Trained on general data — no idea what your machine actually supports
Uses your machine's actual control documentation
Guesses at M-codes, G-codes, and control syntax
Every fix referenced against verified source material
"Try this and see if it works…" — days of back-and-forth
Fix delivered in under an hour, with a diff showing exactly what changed
$2,000–$4,000/year to your CAM vendor — weeks of waiting
From $99/month — replaces your $4K+ annual support contract
Supported Controls

Full MP language support. Postblocks, predefined variables, format strings, and the NCI pipeline. From X2 through 2025.

Fusion 360 / Inventor CAM / HSMWorks
.cps
Supported

JavaScript-based posts shared across all Autodesk CAM products. Callback structure — onOpen, onSection, onLinear, onCircular — and the full Autodesk post API.

BobCAD-CAM
.bcpst
Supported

Text-based post processor with numbered Post Blocks, Post Variables, and Post Questions. Supports VBScript and Lua scripting for advanced customization.

Pricing

Replace your support contract. Save thousands.

Most shops pay $2,000–$5,000/year for post-processor support that takes weeks. Get the same fixes in hours, for a fraction of the cost.

FAQ

Common questions

Generic chatbots guess at M-codes and machine behavior based on training data. Our system retrieves the actual programming manual for your specific control — the same documentation a human post-processor developer would reference. The result is a fix grounded in real documentation, not a plausible-sounding guess.

No — and neither does any other post-processor support service, including your CAM vendor. We provide informed modifications based on your machine's control documentation. You verify the output on your machine, just as you would with any support provider. We recommend single-block dry runs for all changes.

Currently Mastercam (.pst), Fusion 360 / Inventor CAM / HSMWorks (.cps), and BobCAD-CAM (.bcpst). If you need help with another platform, reach out — we may be able to help.

Full refund. If our system can't generate a confident fix, we'll review it personally. If we still can't solve it, you get your money back within 3 business days.

We offer two subscription plans. Pro at $99/month includes 20 fixes per month with 24-hour turnaround. Enterprise at $299/month includes 100 fixes per month with white-label branding and API access — designed for businesses that provide post support to their own clients. One-off fixes are available from $49 if you're not ready to subscribe.

Most shops pay $2,000–$5,000 per year for post-processor support from their CAM reseller. That typically gets you phone/email support with 2+ day turnaround, limited to one CAM platform. cncpostfix.ai's Pro plan at $99/month ($1,188/year) gives you faster turnaround — usually within 20 minutes — support across Mastercam, Fusion 360, and BobCAD-CAM, plus a documentation library that gets smarter with every fix. Enterprise at $299/month ($3,588/year) adds white-label branding and API access for businesses managing post support for their own clients.

Most fixes are delivered within 20 minutes. All plans include 24-hour turnaround as a guarantee.

Yes. Your files are encrypted in transit and at rest. We retain them only for the duration of your fix request (up to 90 days) and never share them with other customers.

Submit a request anyway. If you can upload your machine's control programming manual with your request, we can support virtually any CNC control. Once we have the manual, all future requests for that control are faster.

Still have questions? Email us — we usually reply within a few hours.
