Replace Uno with 3 axis board?

Hi,

Which board do you recomend?

I want to eliminate as many wires as I can.

Is it possible to use a CnC control board that already has an Arduino built-in or the ones that you can use a Nano with - to replace an Arduino Uno with all the wires?

It's a mess.

I want to use my own sketch. No, Gcode. I this possible with those boards?

I'm using an Uno, with a TMC2130 and Bluetooth. I need a board that's well documented. I need the pins labeled.

Here's a post that I found that documents the KeyeStudio CnC board.

Thank you.

How do you mean; there are not many wires as far as I can see. The bluetooth module is 2 or 3 wires plus power/ground, the TMC2130 has 4 or 5 plus power/ground (omitting the connections to the stepper as you need that anyway).

I think that one of the newer Nanos has integrated BLE, just check out the Nano boards in https://store.arduino.cc/.

You can also stack one or two proto shields on top of an Uno and mount the modules on them and wire with short wires.

Thank you for your response.

All those wires for the TMC that you mentioned, are the ones I want to eliminate. I know there are only 4 of 5, but I want to eliminate them.

Is there any reason why I can't use a board 3 axis board? By the way, I forgot to mention in my post that I don't want to use Gcode. I want use my own sketch.

Here's a post that I found, but this guy is using Gcode, but he documents the KyeseStudio board pretty well.

I hope I'm making sense.

ESP32 also has classic Bluetooth, BLE and WiFi. There is a version of grbl for the ESP32, too. And some CNC shields made for ESP32.

Thank you,

I'll look at this board.

Hi,

As you cans see from my original post; I want to eliminate as many wires as possible. I want to be able to plug the TMC2130 right into the board without wires. If I use a Cnc control board, I'll be able to plug the TMC right into it and add two additional steppers motors as I need them.

I forgot to mention in my original post that I'm also using a rotary encoder that uses three D pins. All together I have the Bluetooth module, rotary encoder, and the TMC2130.

Here are a couple of CnC control boards that I will like to get your opinion on. They have a lot of D pins available. I should be able to use those pins for my purpose instead of limit switches or whatever the label says. I'm I right about that?

So here's what I'm trying to accomplish.

  1. Elimate the wires for the TMC2130.
  2. I need the option to add Stepper motors.
  3. I need D pins for the Bluetooth Module.
  4. I need D pins for the Rotary Encoder.

So the simple question is, can I use any of the D pins on these boards for my purpose instead of what it's label for?

Thank you....I hope this makes sense.
