From the original Synthetos forum (2011–2025)
I am wondering if there is CNC control software for the TinyG that does not require an internet connection. I would much prefer to control the TinyG based CNC machine with software that resides on my PC than depend on a slow internet connection.
Does such software exist?
That of course depends on your definition of 'control' and the desired sophistication of your work flow.
A quick short list would include:
CoolTerm - Terminal emulator for CLI level control and a basic file sender
UGS (Universal gCode Sender) -
CNC.js -
Goko -
You'll have to dig in to their on-line documentation to see if they fit your needs.
This is very helpful. I will look into these. Thank you!
Anything that supports GRBL.
Thanks Zootalaws
The TinyG support in Universal Gcode Sender is quite new. If you do decide to try it out I would appriciate any feedback.
Visit https://github.com/winder/Universal-G-Code-Sender for downloads and for posting issues.
I sure will.
Thanks.
@Breiler I will give UGS a go right now - setting up and testing multiple ways of connecting via network to TinyG - ESP32 transparent bridge, SPJS, Websockets, etc.

Like the OP, I also want to control TinyG offline.
I want to try Universal Gcode Sender on a Raspberry Pi 3 B+ with a TinyG ver 8 board. I have X,Y,A axis.
Does UGS support rotary (A) moves?
Does the standard UGS work well with TinyG, or should I use the fork by John Lauer that supports TinyG's JSON formatting for sending Gcode?
What is the recommended method for getting my GCode files over to the Pi?
Are there any tips / issues I need to be aware of to make this combo work? I haven't purchased any boards yet.
Regarding moves on the A-axis it should work using Gcode, but there is no support for displaying the coordinates or visualising yet. That is a current work in progress: https://github.com/winder/Universal-G-Code-Sender/issues/1068
The TinyG/g2core support is quite new and I haven't had the chance to test it with a TinyG boards yet. I've been developing on a g2core board which seems to work: https://github.com/winder/Universal-G-Code-Sender/issues/1071
Regarding transferring files, this is outside the scope of UGS and a bit dependant on your setup. Maybe a USB-stick or SFTP?
