This is the Calibration Torture Test we use for our tests on reconfigured firmware on the   Ender 2 Pro

Gorilla Tech Programming Group.

We are also part of the “All Things Ender 2 Pro” group here on printables.com

We have over 50 members who use the Ender 2 Pro, and we all work together to solve problems, fix bugs, and general mods for the Ender 2 Pro. Even if you do not own an Ender 2 Pro, all are welcome.

I am part of a group of programmers and Ender 2 Pro hobbyists who love 3D Printing and doing mods for them.

We have created a firmware BETA edition for the Ender 2 Pro v4.2.3 main board.
