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.
