klipper on printrbot rev D

These instructions I was using on a raspberry pi board with raspbian Jessie connected to printerboard and running OctoPrint. I wonted to use RPi for a second printer that I am building, so it was time for me to switch to klipper.

Klipper firmware

You can probably run one of the klipper install scripts, but I decided at first to compile firmware and see how far I can get.

sudo apt-get install gcc-arm-none-eabi

git clone https://github.com/KevinOConnor/klipper

cd klipper

make menuconfig

Select options as shown on the screenshot:

Save your configuration by hitting Q and Y (Save)

make

If everything goes well you should have ./out/klipper.elf.hex file generated

Flashing

Start by installing dfu programmer. Before doing this I also tried teensy_loader_cli but without much success.

apt-get install dfu-programmer

On the printrboard set jumper to boot. Device did not appear as DFU loader right away, so I had to click reset button. If you run lsusb you should see DFU bootloader device:

At first I tried to flash without erasing and was getting errors. I also found that you need to use sudo otherwise it won't work. To erase/flash run these commands:

sudo dfu-programmer at90usb1286 erase

sudo dfu-programmer at90usb1286 flash <path>/klipper.elf.hex

Power down device and remove jumper. Power back up. You should see Klipper device.

Success!

Printrbot 1405 Marlin compile on OSX

I continue doing modifications to my printrbot, which has almost no original parts left. Occasionally, I need to make changes to the source code running on the board to flip y axis, force z axis power etc. This post is some notes to walk you through this process on OSX. As of writing this post I compiled it on iMac with High Sierra 10.13.6.

Download and install Arduino IDE. In my case I was using version 1.8.9.
You will also need to install Teensyduino.
Clone Marlin repository for printrbot:

git clone https://github.com/Printrbot/Marlin

Open source in Arduino IDE and compile Marlin by clicking "Verify".

You should see a Teensy helper window pop up. Find compiled binary Marlin.ino.hex by navigating through the window.



To flash you will need to build and compile dfu-programmer from this repository https://github.com/Printrbot/FirmwareUpdatr. After running build you should have dfu-programmer executable. Now you are ready to flash the board.

Set boot jumper as described in this link and on the image below. The picture is for Revision D of the printrboard. Note that after you set this jumper serial port is no longer visible. Power the board, connect USB and press reset button.

To erase and flash run two commands show below. If you do no


If you see an error message “dfu-programmer: no device present.” make sure your device is connected and try to press reset button.

If flash succeeded you should be good to go. Remove the jumper and reconnect the power. G-codes can be found here https://reprap.org/wiki/G-code
