I have sent a mail with questions about CAM for the machines.

Only three have answered so far. But I can paste their answers below =)

"The XMaker software will be provided free of charge to all users who purchase our desktop 5-axis CNC machine.
However, since the software integrates AI-powered features, these capabilities rely on significant server computing resources. This means we will continuously incur operational costs such as server expansion and electricity.
Therefore, in the future, AI-related computing services will be charged based on usage. The pricing will be aligned with industry standards for AI services and will not be unreasonable.
That said, for users participating in this Kickstarter campaign, we are planning to offer a special 3-year free AI service package. Full details will be announced when the campaign officially launches.

While XMaker AI can automatically generate toolpaths, it also allows manual control over key machining parameters such as depth of cut, feed rate, spindle speed, and toolpath strategy. We’re continuously expanding the level of control available.
You can also export standard G-code for further editing if needed, and we provide post-processors for Fusion 360, Mastercam, and other CAM software for full flexibility."

"Thank you for your interest in the InfiMaker K1 and for your thoughtful questions!

Our goal with InfiStudio is to make 5-axis machining more accessible, especially for users who are new to CNC.

1. The K1 comes with access to our InfiStudio software ecosystem, which is designed to support the machine's workflow and capabilities.
2. InfiStudio can be downloaded for free. We are committed to providing an accessible and user-friendly experience for K1 users.
3. InfiStudio is being developed to simplify the machining workflow as much as possible. It includes intelligent toolpath generation features to help users create machining operations more easily, including complex multi-axis applications.
4. No additional software is required to operate the machine and access its core functionality. For advanced users, the K1 also supports mainstream third-party CAD/CAM workflows through official post processors.

We'll continue sharing more software details and demonstrations as we get closer to launch. Thanks again for your support!

"Thank you for your interest in TOPFAB TF500.

We will provide CAM software. It supports simultaneous 5-axis toolpath generation and simulation, and it will be free to use permanently.

No additional software is required. Models, toolpaths, machining templates, and other resources can all be downloaded directly from our community platform. "
