Our gControl Panel Computer is a touch-screen interface designed to be part of the full ecosystem for CNC machine control, working with gSender (pre-installed), AltMill and LongMill CNCs, and the SuperLongBoard family of controllers. It’s also a fully functional Windows computer that can run other programs, connect peripheral devices like a mouse or keyboard, support an external display, and send commands.
gSender comes pre-installed and configured so that you can get started with your CNC right out of the box without any additional software installation.
It can control any CNC machine compatible with gSender and run any other Windows-based CNC control software.
When you purchase the gControl Panel Computer, you’ll receive a mounting solution that works with all AltMills and LongMills, as well as many other workbenches.
Mounting bracket included. Please specify your AltMill size in the order notes at checkout so we can include the correct bracket (4×8 or 4×4/2×4).
The gControl Panel Computer ships as an individual item in its own packaging and may arrive separately from other orders.
The gControl Panel Computer is a fully functional Windows 11 (64-bit) PC designed to control your CNC machine and run gSender, connecting seamlessly with your AltMill, LongMill, or other compatible CNC systems. Its touchscreen interface lets you send commands, jog axes, adjust settings, and run jobs, while also functioning as a standard Windows computer that can connect to other devices and run additional software.
The gControl is compatible with CNC systems that use USB or Ethernet-based motion controllers.
To ensure smooth operation, your CNC system should: Communicate with the Windows PC via USB or Ethernet.
Run control software that supports Windows 11 (64-bit).
Systems that rely solely on parallel port connections are not supported unless upgraded with a USB motion controller. For the best experience, we recommend confirming software and driver support with your CNC or motion controller manufacturer before use.

Great value tablet that comes pre-configured for easy plug n play. Edges of screen do get warm. Would love to see an online g-code manual and user defined variables (e.g., for multiple zero points).

It’s excellent. I can run Fusion 360, Lightburn, gSender, etc. with no issue. It boots quickly and easily wirelessly connects to my network. I couldn’t be happier.

Feels like a good deal overall, given that it includes mount, computer, and touchscreen. THe form factor feels a little less “Sienci-ish”, as it’s not a super clean install w/ more wires, etc. I’d think there’d be something like running wires inside the mounting tube so that it’s really clean. Understand it’s not meant to be just like a Masso, but, Sienci has a continued opportunity to innovate and be the Apple-like solution to this market segment.
BIGGEST ISSUE: Needs a matte screen surface. This alone made me want to follow FrancisCreation’s path and use his setup with, IIRC, a larger matte screen.

My only knock on the computer is the sensitivity of the touch screen. It seems to vary randomly. At times I seem to have to touch repeatedly to execute a command but I’ve also accidentally started the spindle rotation by accidentally brushing across the screen, I’ve started using a mouse for most operations to avoid this.

My advise to anyone getting a CNC is to get the Gsender. I am simply amazed at how easy this thing works. No more bulky computer attached to the CNC. I am so glad that I got one along with my Altmill. Everything is in the Gsender. Hats off to the genius who developed it.

My only suggestion for an improvement is in the mounting bracket. It would be nice if it had more movement and could swing about more. In the small space I have, it gets in the way quite a bit.
