CNC Arduino Nano GRBL 1.1
Today I would like to present you our latest creation in the field of CNC control cards from ArduinoClub.
A GRBL 1.1 compatible CNC motion controller based on the Arduino Nano.

ArduinoClub Arduino Nano GRBL 1.1 CNC Controller
The data of the GRBL 1.1 Nano control card :
- Connection possibility for drivers or motors for 3 axes, also several motors/drivers per axis.
- Then of course limit switches for all 3 axes, also 2 limit switches per axis.
- Relay output to switch cooling water.
- Probe; length sensor, touch plate, stylus etc. can be connected in parallel.
- Connection for buttons; program start, program pause, program continue, abort and hardware reset.
- Connection for frequency converter/HF spindle, 0-10V, or 0-5V output, adjustable.
- Switching of DCM/FOR, for the frequency inverter.
- Extra relay output for switching milling machines without frequency converter e.g. AMB (Kress) also AMB machines with 0-10V input.
- Possibility to display the switching status of the limit switches.
The components are supported by a professionally produced white PCB with black lettering in the size 106x78mm.

Hello, what is JP1 for?
This allows you to set whether the VFD output should work with 0-5V or with 0-10V.

hi, can i connect home switches for x,y and z in paralell or even better, can I connect all 3 homming sensors and have one input for homming the machine?
No, that is not possible.
You can connect 2 limit switches to one input, but then, for example, X+ and X- to input Limit X, Y+ and Y- to input Limit Y and for Z then, Z+ and Z- to Limit Z.
Or X- to limit X, Y- to limit Y etc.
Greetings

Is it possible to have dual motors on one axis with this board?
Dear ArduinoClub
I bought a nano grbl board , all work fine but no out for SPINDLE and INVERTER . How I connect spindle? I need a analog out to control motor speed and on/off out. Pin SpRel no out , Pin inverter 8,73 V when spindle goes on.
Can send us a schematics so ,in case of failure, I can repair the board by myself? Regards
Hello, switch on the spindle and enter 100% power in the software, now you can adjust the blue potentiometer clockwise until you have 10V at the VFD output.
Did you see the note about programming GRBL1.1 ?
