UART connection for Orange Pi Zero 2W #22

Open mysteryjeans opened 11 months ago

mysteryjeans commented 11 months ago

Uart cable connector for RX & TX should be separate from 5V, 5V & GND.

Orange Pi Zero 2W has reserved GPIO pin 8 & 10 for UART0 for debugging & console.

If RX & TX cable were separate, then UART5_TX on GPIO pin 11 and UART5_RX on GPIO pin 13 can be utilised.

@mysteryjeans Any solution found?

mysteryjeans commented 5 months ago

@andriib-huma I had to use USB LAN to setup WiFi. Using UART5 for data, check the picture & screenshot of BOM file.

@mysteryjeans Thanks for update. I tried to use UART5 and for some reason did not get any success. Used Debian Bullseye from OrangePi website. Tested UART5 pins according to this guide. Saw pings according to the test. Did't get it working for actual MCU connection. Only via USB connection. Can I ask you to share orangepi-config/System/Hardware config? Is there any extra steps that you did to make it work?

mysteryjeans commented 5 months ago

@andriib-huma did you compiled MCU firmware with UART5? You need to put MCU in boot mode before flashing firmware.

I followed this guide https://youtu.be/qtmPxSt6baU?si=DljXsvXGmKQBSn27

[safe_z_home] home_xy_position: 100.2, 34.08

A X, Y coordinate (e.g. 100, 100) where the Z homing should be

performed. This parameter must be provided.

speed: 50.0

Speed at which the toolhead is moved to the safe Z home

coordinate. The default is 50 mm/s

z_hop: 5

Distance (in mm) to lift the Z axis prior to homing. This is

applied to any homing command, even if it doesn't home the Z axis.

If the Z axis is already homed and the current Z position is less

than z_hop, then this will lift the head to a height of z_hop. If

the Z axis is not already homed the head is lifted by z_hop.

The default is to not implement Z hop.

z_hop_speed: 15.0

Speed (in mm/s) at which the Z axis is lifted prior to homing. The

default is 15 mm/s.

move_to_previous: False

When set to True, the X and Y axes are reset to their previous

positions after Z axis homing. The default is False.

@mysteryjeans Thanks again. I was also inspired to give my first printer a new coat of paint because of The 100 Project)). So I was able to to make it work. Not sure why it didn't in the first place. But I reflashed the SD Card, enabled UART5, connected everything, and it worked.

So I will leave some of my steps for troubleshooting the issues.
