Troubleshooting
Trial and licensing
Section titled “Trial and licensing”The trial ended — is my work gone? No. Projects always open. Saving and exporting G-code lock until a license is activated, then everything unlocks in place.
Activation fails. Activation needs a brief internet connection to register this machine against your key. Check the connection, check the key for typos (dashes included), and try again. Day-to-day use doesn’t need the network.
I’m replacing a computer. A license activates on up to 3 machines. Retiring one? Email us and we’ll sort the activation out.
Updates
Section titled “Updates”The app checks for updates and shows a banner when one is available for your license — updates are included for 2 years from purchase, and the changelog lists what’s new. After your update window ends the app keeps working; renewing adds 2 more years.
Cutting problems
Section titled “Cutting problems”The cut is mirrored or offset. Almost always a setup mismatch: the machine was zeroed on a different corner than the setup’s origin corner, or Z was zeroed on the bed while the setup says stock top. Fix the setup or the zeroing — they must agree.
An operation refuses my bit. That’s the cuttability check catching a real mismatch — a cutter wider than the slot it would need to enter, or a fill operation aimed at single-line text. Use a smaller bit, adjust the geometry, or switch to the engrave operation for centerline text.
Still stuck?
Section titled “Still stuck?”Email support@chantocnc.com — include the project folder if you can; it contains everything needed to reproduce what you’re seeing (fonts included).
