I am very proud to present to you this new version 2.0 developed with Mstrens and the participation of other forum members, we have greatly improved the functions of the V1.0 / 1.5 kit while making it more reliable, easier to wire and to use 🙂
The GRBL 32bits board V2.0 kit is a CNC control kit up to 4 axes, it’s universal, can be mounted on all CNCs equipped with external drivers such as TB6600 or DM542 for example .
Its particularity is that it is autonomous, you can fully manage the CNC without a computer thanks to its TFT touch screen combining all the functions of CNC software, but it’s of course possible to connect a multitude of devices, there are more ten connection possibilities thanks to its exceptional connectivity.
Complete solution, powerful, precise, easy to use and to implement thanks to the tutorials, it is as well suited for beginners as for experienced, all for a ridiculous price for its performances and possibilities!
Firmwares are Open Source, GRBL ESP32 1.3 for the control board, and Firmware developed by Mstrens from the forum for the TFT module.
The GRBL 32bits board kit is assembled and shipped from France exclusively by MakerFr
GRBL 32bits board V2.0 details:
- 32 bits, so in terms of frequencies, it’s more the drivers that will limit us rather than the board!
- Wifi and bluetooth for many connection possibilities
- Amplified signals, as the ESP32 I/Os operate at 3.3v, the signals are amplified at 5V for compatibility with a multitude of external drivers such as the TB6600, DM542, …
- Limit switches fully isolated by optocouplers and DC / DC converter to no longer have to worry about interference.
- Integrated RC filters, on the control switch terminals.
- External 5V power supply for more reliability
- Low purchase cost of the ESP32 module (Around 5 €)
- GRBL ESP32, a real CNC special open source firmware that opens up a lot of possibilities and options, regularly updated.
- Modification of firmware options without needing to flash the board, just with simple command lines under serial console or via web interface.
- Removable SD slot directly on the GRBL card and SD slot on the TFT, both accessible from the TFT menu!
- Integrated spindle relay to manage the start-stop of single spindles, PWM and reverse PWM outputs to manage variable control spindles, VDF, lasers …
- Multitude of I/O accessories: Probe, Coolant mist, Reset soft, Feed Hold, Cycle start
- RJ45 sockets to connect the TFT to the GRBL card, this solution makes it possible to have a cable already crimped, shielded and with keying, thus avoiding human errors.
- Screw terminal block for easy wiring
- Possibility of connecting the 3 XYZ axes + a 4th rotary (XYZA) or 3 axes with two Y motors with automatic perpendicularity adjustment at each Home (XYYZ)!
TFT module details:
- 3.2 “touch screen (possibility to adapt a 4”)
- Easy editing of macro buttons
- SD Slot: Allows reading G-code files and loading additional custom buttons very simply without needing to re-flash the firmware
- Completely open source and modifiable at will, developed by Mstrens of the MakerFr forum and regularly updated
- Nunchuk socket integrated on the front to connect a WII Nunchuk, to move the axes of the CNC
- 3 languages to choose from: English, French, German
- Customizable colors of all TFT elements
- For the many functions, see the TFT user manual
- Wifi and bluetooth for many connection possibilities
And a complete tutorial, and support on the forum!
