This time the test is performed by connecting the two boards (motherboard + expansion card) on a big CNC to convert it from Mach 3 to ESP32-GRBL!
Even this test has been succesfully passed!
Month: March 2019
The testing phase of all the boards’ functions goes on! This time we will try to control the laser cutter, which I built myself refurbishing an old pick-and-place machine for SMD components.
Today we are testing the complete version of the project (motherboard + expansion card + stepper driver) on my toy CNC. As you can see from the photos, the steppers are directly controlled by the drivers mounted on the expansion card. It seems to work properly!
"Motherboard only" version
This version consists of the motherboard only. Recommended if you are building your own CNC machine from scratch.
"Motherboard + Expansion Card" version
This version includes the motherboard and the expansion board. The latter is required if you want to use the additional I/O lines and the LPT-style connection. Recommended if you wish to convert an old CNC machine from Mach3-LPT style to ESP32-GRBL style.
"Embedded stepper drivers" version
In this case, the expansion board also mounts the stepper drivers, which must be duly cooled with a heat sink. Recommended if you want to build a desktop CNC machine.

This is the assembly, step by stesp, of the complete controller (motherboard and daughtercard with the motor drivers on board).
In the download page you will find also the step files of the parts printed in 3D.
We decided to “give a good dress” to the boards: some 3D printing for the chassis and milled aluminum for the front panel…
Soon we will publish the models files on dowload section!
