No connection

Post by runcool » Thu Jan 24, 2019 5:20 am

Hi,
I bought the board along with A4988 driver to make a simple XY plotter.
setup
Raspberry Pi - model: 3B
Protoneer board: 2.6
Pi CNC HAT Version 4.10 from here https://wiki.protoneer.co.nz/Raspberry_ ... Card_Image
Nema 17 Motor
Power Supply: ATX supply with 12v output
Setup the driver with the vref based on the instruction.

Status:
- pi boots up and I'm able to load the bCNC and after updating to /dev/ttyAMA0 it still doesn't connect. the app freezes the moment I click connect.
- I've tried rebooting and trying minicom and there as well I'm not able to connect to /dev/ttyAMA0 also. Same story with CNC.js.

I'm helping a 7th grader to set this up for their STEM program. Any help would be appreciated. Thanks!

Have you run the RPI 3 setup script that is on the desktop?

By setup, you mean setup minicom? If so that I did that.
I followed the guide here https://wiki.protoneer.co.nz/Raspberry_ ... tart_Guide

Please tell me more about the setup script.

To setup a RPi 3's, run the "RPi3 Serial Config" shortcut on the desktop it will configure the hardware serial port and is only needed for on a RPi 3's. It only needs to be run once and will automatically reboot the Pi.
RPI 3's is sharing the the Bluetooth port and hardware Serial pins. By default bluetooth is enabled. The above swaps them out.

Are you saying the onboard bluetooth has to be disabled? If this is true I wish that was posted in a MANUAL or on the manual wiki because if it is true. Then this project i have been building up towards, and am just starting to work on getting the electronics and software side going. Will have been a total waste of my time and money and I'll will FULLY and TRULY wish I had never purchased it. I need to use the bluetooth being that its part of my BT wireless control system for lockout tag out. does bluetooth have to be disabled yes/no?
