Dev2: Serial port USB issue

[JeppeIbsen]

I'm testing the dev2 repetier on one of our custom cartesian printers, with bare due electronics connected to octoprint on a pi.

Unfortunately when the v2 firmware is uploaded to the due, there is no longer any open serial ports and it's not possible to connect. I have to upload a blink sketch to the programming port to reach the due again. I have been using the v1 repetier on different printers throughout the years, but the configuration on the v2 is somehow wrong for my setup.

Configration h: https://pastebin.com/fLPndPRE

Radds.h where the pins are defined: https://pastebin.com/arhDfULH

platformio.ini: https://pastebin.com/jwfcHy6P

How do I correctly configure the v2 firmware, so I can connect to it via USB ?

[repetier]

bare due electronics So no RADDS board as you defined it?

Which usb port do you want to use. You have

define RFSERIAL SerialUSB

which is the native usb port. For programming port use Serial or to use both set

define BLUETOOTH_SERIAL Serial

If it is no radds and you have no eeprom add in configuration.h

define EEPROM_AVAILABLE EEPROM_NONE

If these are all changes to default cartesian config it should compile and already connect. If not best is to go back and add changes incrementally when a first version worked, so you know wher ethe problem arises.

I also saw you did not mention configuration_io.h which is in V2 an important part of the configuration!

Unfortunately even when defining eeprom_none, there is still no USB access to the arduino. Windows claims that 'USB device not recognized' every 30 seconds, it might be resetting.

Do you have a 'working' image of the firmware, for a bare-due ? I can then work forward from that. I looked into the configuration_io and it seemed OK, however we don't use TMC2130 drivers, but I dont now what an alternative confugration in the file would look like.

The configuration_io.h is here: https://pastebin.com/LqLqLKcc

Check cartesian/felix pro for regular stepper drivers. They just use STEPPER_SIMPLE(name, stepPin, dirPin, enablePin, minEndstop, maxEndstop) https://docfirmwarev2.repetier.com/config/motors#stepper_simple

instead of the trinamic. Might also be the source if spi does not work on set pins.

I have no bare due sample. Default config with radds and eeprom mode 0 should work on bare due also it will freak out from defect thermistor but should give some lines on connect with reset over programming port which it uses.
