It is and we’d recommend you check it out! gSender is built off of the already sturdy code infrastructure of CNCjs, plus after over 5 months of Alpha testing then Closed Beta testing with over 300 people it's now been out in the wild since May 2021. Since public release, gSender is now trusted by many thousands of people - and counting - to easily and reliably run their CNC routers every day. In many cases, the capability of the CNC can be dictated by the limitations of the software; we hope you notice the difference with gSender.
gSender is a free program available to be used for many different CNC routers on the market. To download the latest version, there's a box above on this page titled "Downloads" which is always kept up-to-date as we continue to release new features and improvements.
This page will always link to download the latest version of gSender. If you’d like to see the particular version number, you can find it on this page (https://github.com/Sienci-Labs/gsender/releases) and cross-reference it to the version number that appears in gSender’s top toolbar or in the Settings -> About page within gSender
As long as your CNC is GRBL-based and has a minimum of the GRBL 1.1 Firmware then you’ll be able to control it with gSender. As of now, gSender only has easy control of 3-axis machines.
gSender is built to work on Windows/PC (Windows 7 and up), Mac (El Capitan 10.11 and up), Linux, and even Mini PCs or single board computers like a Raspberry Pi. No matter the computer used, our minimum recommended system requirements would be:
- 2GB of RAM
- 1280 x 768 screen size
Yes! It's got a global toggle so that everything can be in either mm or inches. It also accepts mm and inches files.
Not at all. gSender can be run completely standalone once you’ve downloaded the install file. One feature that won’t work without an internet connection is gSender’s ability to automatically check for updates to keep itself up-to-date, though you can always manually install a newer version on top of the current version yourself.
UGS and gSender have far more similarities than they have differences. Although gSender has yet to catch up to UGS in its depth of features, the features that it already has are plentiful and should suit the needs of all beginner CNCers as well as most individuals with an intermediate level of CNC experience.
No. gSender is strictly a CNC control software and has no features currently for gcode generation outside of some additional features like it's surfacing and bed levelling tools. You'll need to use gSender in combination with some other CAM, or design + CAM, software to create your full CNC toolchain.
