Questions, answered

What's included in the free trial?

Everything. The 30-day trial is the full app — every drawing tool, every toolpath operation, the 3D simulator, and G-code export. No account required.

What happens when the trial ends?

The app keeps opening your projects, so nothing is lost. Saving and exporting G-code lock until you activate a license — then everything unlocks again, right where you left off.

How does activation work?

Buy a license, get a key by email, and enter it in the app. Activation needs a brief internet connection to register the machine; day-to-day use doesn't — the license is stored locally.

How many machines can I use?

One license activates on up to 3 machines.

What do updates cost?

Your license includes 2 years of updates from the day you buy. After that the app keeps working forever with the versions you have — renew whenever you like to get new versions again.

How do renewals work?

Renewing adds 2 more years of updates to your existing license. Enter your key on the Renew page, complete checkout, and every activated machine picks it up on its next start — nothing to reinstall.

Which machines does it support?

Any CNC router that takes G-code from GRBL, LinuxCNC, Mach3, Marlin, or Masso post-processors, with per-setup control of origin corner and Z zero. If your controller isn't covered, email us — we will do our best to include it in the next release.

Still stuck?

Email us — a human who works on the app reads every message.
