Sienci Labs

Sienci Labs We make machines that turn trees, rocks and whatever plastic is made from, into cool stuff.

If you've bought a machine that makes cool stuff from us, you can find out when it's going to arrive so you can do stuff: https://sienci.com/order-status/ Sienci Labs emerged from research and testing to create low-cost mechanical systems for rapid prototyping tools like CNC machines, 3D printers, and laser cutters. Founded in early 2016, our vision is to make automated manufacturing and rapid pro

totyping technologies accessible for both technical and non-technical makers alike. The Mill One was our first step toward bringing affordable and easy-to-use CNC routing to the world. The Mill One gave users the ability to cut and engrave into almost any of the most readily available materials you can access, with an impressive level of detail, while also being able to engrave into existing objects or produce working circuit boards. The LongMill, our newest machine, expands on the Mill One by offering a larger working area, more power, and more making possibilities. Since our inception, we have put CNC machines in thousands of homes, workshops, classrooms, garages, and more in over 40 different countries.

Our new Tool Length Sensor (TLS) is now available.

https://sienci.com/product/tool-length-sensor-kit/
https://github.com/Sienci-Labs/gsender/releases

It requires gSender 1.6.2 or higher to operate.

Compatibility:
- Any size or version of the AltMill
- Any size LongMill MK1-2.5 (requires limit switch upgrades)
- Any size LongMill MK3
- Other CNC brands with proper controller support: (a) They must be able to supply a 5-24V to a TLS and can operate with a normally closed (NC) TLS input; b) Major brands with controllers that support a TLS include Onefinity, Shapeoko, Genmitsu, Carbide 3D and many more; c) The TLS is designed for flat wasteboard surface mounting

---------------------

What's a Tool Length Sensor (TLS)?
A TLS is a probe, fixed to your CNC machine, used to measure the length of your cutting tool. It will greatly enhance your workflow, as it maintains your z-axis zero position across multiple tool changes. It measures the relative offset of your tool length, whether you're using different tools or changing the stickout of your tool in the collet. It's essential for businesses or hobbyists looking for more consistent, precise and reliable cutting jobs, and it greatly speeds up setup time.

https://sienci.com/2026/05/28/gsender-1-6-2/

We cleaned up some gSender Edge-case issues that stemmed from 1.6.0 Main, along with some workflow improvements surrounding firmware compatibility and ATC/tool change flows.

***General Release Notes***
Updated defaults for better TLS/probe misconfigurations; corrections to SD cards/ethernet issues; laser power slider fixes; tool change wizard UX upgrades; real time macro commands; and a whole lot more!!!
