Mellow "ERCF Fly Board V1.1" USB Setup

Description

I've joined the ERCF club and purchased a Blurolls kit from Aliexpress which came with a Mellow "ERCF Fly Board V1.1" It took me a good few hours to find all the info I needed to get it up and running so I thought I would document the steps to save someone else the time later. This is a work in progress

 

 

Initial setup of UART Jumpers on the ERCF Fly Board v1.1

 

Make sure that you install the jumpers as shown below or you will run into issues further down the line.

Flashing klipper to the Mellow ERCF Fly Board v1.1 to use a USB connection.

 

SSH into the Raspberry Pi

On the Flyboard hold down the SW1 button and attach USB cable to Raspberry Pi (or other micro board) then let go of reset button.

Type 

lsusb

Look for ‘ID 2e8a:0003 Raspberry Pi RP2 Boot’ in the list of devices. If it is not present repeat the process.

When you have confirmed that ‘ID 2e8a:0003 Raspberry Pi RP2 Boot’ do the following:

  

cd ~/klipper               
make menuconfig

 

Select the following options for a ‘USB’ (not CAN) connection to your printer. Make sure enable extra low-level options is selected.

Exit & save 

make -j4                			   #This will compile the firmware for the ERCF Fly Board v1.1
make flash FLASH_DEVICE=2e8a:0003		      #This will flash Klipper to the ERCF Fly Board v1.1

 

 

If successful it should look like the image below:

Disconnect and reconnect the ERCF Fly Board v1.1 USB connection from your Raspberry Pi and reboot your Printers Host

 

You can then move onto installing ERCF-Software-V3 "Happy Hare" by moggieuk

Instructions here: moggieuk/ERCF-Software-V3: New software driver for ERCF control under Klipper (github.com)

If your flashing was successful, you will be able to use the ‘Fystec ERB Burrows Board’ option throughout the install as it will detect the ‘Raspberry RP2040’ mcu.

Use gpio(then the corresponding pin number) in your ercfhardware.cfg 

e.g.
gpio20 for the endstop  (P20)
&
gpio7 for the STEP pin on gear stepper (GPIO7)

Note: adding a ‘!’ before gpio will change the movement direction.

 

Hopefully that will help someone!

Hello everyone,

I'm trying to install mellow fly board after I had on the same port an Ercf easy board (the trianglelab kit one). I'm also having issue with the reset and my raspi cannot see the usb attached (i'm tryng to use the same connection I had before with the easy board, don't know if this thing change something in my new installation). I will try to clean with ethanol and insist with the reset button thanks. But I was really looking for installing CAN connection but I really don't know what to do and which ports to use (on the raspi maybe???). Can someone help me understand please? I have got a raspi 3b+.

The Canbus connection is not on the Pi but on the motherboard or Canbus adapter. Which motherboard do you have installed?

The Canbus connection of the Octopus Pro is the RJ11 connector on the motherboard.

I'd recommend you purchase this RJ11 adaptor to connect the High/Low wires of the Canbus.

Here is the location of the high-low Canbus terminal ( 2 & 3)

Here is the link to flash the Mellow ERCF V1.1 board. Mellow ERCF

Yeah thanks, I was trying to follow that already for the usb connection, but I encountered that reset button issue that was pointed out in the firsts comments so I should retry with cleaning maybe. And then, just to say everything at this point, I think I didn't install correctly katapult because I had an error during the first compile, so I just tried to skip that part to see if it works. But I actually had the idea of switching to can bus connection.
