Redeem is the Replicape Daemon that accepts G-codes and turns them into coordinates on your 3D-printer. It's similar to Marlin and Teacup, only it's taylor made for Replicape and it's written in Python.
Software features:
- Accelleration with corner speed prediction.
- Printer settings loaded from file
- Controllable via ethernet, USB, Manga Screen (Toggle on 4.3" LCD).
Redeem documentation on the wiki
Most users should probably use the Kamikaze CNC image, it is a complete BeagleBone eMMC flasher image that comes with Redeem.
If you have a different Debian distro, you can use the .deb packages form the thing-printer feed:
wget -O - http://feeds.thing-printer.com/apt/debian/conf/replicape.gpg.key | apt-key add -
echo "deb http://feeds.thing-printer.com/apt/debian jessie main" >> /etc/apt/sources.list
apt-get update
apt-get install redeem
You can clone this repository directly on your BBB:
ssh [email protected]
cd /usr/src
git clone https://[email protected]/intelligentagent/redeem.git
For Debian, install swig, python-smbus:
apt-get install swig python-smbus
Compile the native path planner module:
cd /usr/src/redeem/
python setup.py install
mkdir /etc/redeem
cp configs/* /etc/redeem
cp data/* /etc/redeem
Get and compile the device tree overlay.
For Kernel 4.1, see the instructions for the new cape overlay repository
Get and compile the device tree overlay. Notice that there has been a change in the DT intefrace between 3.8 and 3.12:
For Kernel 3.8:
wget https://bitbucket.org/intelligentagent/replicape/raw/7bd19bb1be34aa4c32953e8175177d130c6dca10/Device_tree/3.8/BB-BONE-REPLICAP-0A4A.dts
dtc -O dtb -o /lib/firmware/BB-BONE-REPLICAP-0A4A.dtbo -b 0 -@ BB-BONE-REPLICAP-0A4A.dts
For kernel 3.12 +:
wget https://bitbucket.org/intelligentagent/replicape/raw/7bd19bb1be34aa4c32953e8175177d130c6dca10/Device_tree/3.12/BB-BONE-REPLICAP-0A4A.dts
dtc -O dtb -o /lib/firmware/BB-BONE-REPLICAP-0A4A.dtbo -b 0 -@ BB-BONE-REPLICAP-0A4A.dts
Disable HDMI with sound (will load HDMI without sound):
For pre uboot v2014.07/v2014.10/v2015.01 images
nano /boot/uboot/uEnv.txt
Add this line:
optargs=capemgr.disable_partno=BB-BONELT-HDMI
For post uboot v2014.07/v2014.10/v2015.01 images
nano /boot/uEnv.txt
Change this line:
#cape_disable=capemgr.disable_partno=BB-BONELT-HDMI
to
cape_disable=capemgr.disable_partno=BB-BONELT-HDMI
The capemgr does not work with Debian, so the cape has to be enabled manually:
nano /etc/default/capemgr
Add this line:
CAPE=BB-BONE-REPLICAP:0A4A
Enable Adafruit SPI0 overlay on boot - needed for at least March 1st 2015 Debian image for BBB, possibly for everything post uboot v2014.07/v2014.10/v2015.1 images.
nano /boot/uEnv.txt
Add this line:
cape_enable=capemgr.enable_partno=ADAFRUIT-SPI0
Also need to rebuild the initrd image so it includes the Adafruit SPI0 overlay, this will insert all overylays in /lib/firmware. Useful if you need to add future overlays for boot time application. Copied and updated from https://github.com/notro/fbtft/wiki/BeagleBone-Black
Create /etc/initramfs-tools/hooks/dtbo
#!/bin/sh
set -e
. /usr/share/initramfs-tools/hook-functions
# Copy Device Tree fragments
mkdir -p "${DESTDIR}/lib/firmware"
cp -p /lib/firmware/*.dtbo "${DESTDIR}/lib/firmware/"
Make executable
$ sudo chmod +x /etc/initramfs-tools/hooks/dtbo
Backup initrd:
$ sudo cp /boot/initrd.img-\uname - r` /boot/uboot/initrd.img-`uname -r`.bak`
Create/update initramfs:
$ sudo /usr/sbin/update-initramfs
Reboot
After a reboot, you should see a the cape firmware load:
dmesg | grep -i replic
Enable the redeem service:
First modify the redeem.service file to update redeem 'binary' location.
Since the software was sintalled form source, it is added to /usr/local
nano /usr/src/redeem/systemd/redeem.service
Edit line
ExecStart=/usr/bin/redeem
to
ExecStart=/usr/local/bin/redeem
Copy redeem systemd startup script into place, enable it for startup on boot and start it now.
cp /usr/src/redeem/systemd/redeem.service /lib/systemd/system/redeem.service
systemctl enable redeem.service
systemctl start redeem.service
For Angstrom the packages are outdated, install from source. For legacy packages, look here: [http://feeds.thing-printer.com/feeds/v2013.06/ipk/eglibc/armv7ahf-vfp-neon/machine/beaglebone/]
Try to be PEP8 compliant: http://legacy.python.org/dev/peps/pep-0008/
Hi! do an "updatedb" and then "locate Redeem.py". It should give you the location. Please note that if you install from source, the files will have a different location than if you install from a deb package. /usr/lib vs. /usr/local/lib/.
As for the firmware files (the code that runs on PRUSS), they are moved to /tmp during compilation, but should reside in a sub directory from Redeem.py before compilation. A recompile of the firmware can be triggered by touching /et/redeem/local.cfg
