If anyone wants one that runs out in the store, they can have mine. Dosen't work properly, and I cannot get it to work by following the instructions that I have been able to find.

maybe if its just simple parts upgrade, you could sell a little upgrade kit for the DIY solder people for the main issues solved? Like those caps look like the could be replaced in about 5 minutes with newer ones for example. people always like having the newest and best, i just bought a replicape a few weeks back so a little ouch lol.

anyways, im still building my 3d printer so im not even sure how important these upgrades are so maybe its a non concern for most people

Success! The Probe routine (G29) now seems to be working great! I think my WIP DIY probing effector might have some pretty bad accuracy across the bed, but OK precision. I've committed my changes and so I think it's time for a minor bump due to this. Perhaps let it simmer for a bit and get some feedback : )

Yeah, I've discovered this design flaw as well. Perhaps it would be better to have a pull-down resistor on the end stop inputs...

I use the 12V on my sensor which does work, since the pull-up is actually 47K (also a design flaw), so the current going into the 5V regulator is very small.

The input to the BBB is buffered, so it should handle up to 15V. My suggestion is to just connect it to 12V and give it a shot, should work fine!

I made a video documenting the current state of the bed level algorithm. It appears broken to me, not sure when that happened or if it has ever worked exactly as it should. Either way this should serve as a starting point!

I've pushed some new changes into develop today, so beta testing is welcome. A better auto-tune, (still WIP), set slave mode by G-code (M608) and ability to save the bed compensation matrix, apparently that was brokeh.
Note that this new push changes a few things in the config. pid_e_Kp instead of pid_e_P etc., sensor_e instead of temp_chart_e, and the bed matrix has a new format. Check the default.cfg after installing. Would be great to run the config checker during start-up and get warnings on deprecated variable names etc.

I knew my printer could print self replicate. Reprap ftw!

For those of you running Kamikaze 1.1.0 and having Toggle, please update:
https://bitbucket.org/intelligentagent/toggle/issues/19/toggle-fails-to-establish-communication

ssh root@kamikaze.local
cd /usr/src/toggle/
git pull
make install

I've uploaded a new Kamikaze image (1.1.0), based on the previous version, only with updated software installed from Git. This should have the latest Redeem, Toggle and OctoPrint with plugins. What's interesting is that it uses the same method for generating the image as with Kamikaze 2.0 which is still in the works. Feel free to test it out! http://wiki.thing-printer.com/index.php?title=Kamikaze#Kamikaze_1.1.0
Kamikaze is a complete Linux distribution based on Debian Jessie (8.1). It has all the necessary software for running Replicape to control your 3D printer. The way this works is you download an image file, extract that onto a mico SD card and place that SD card in your BeagleBone Black.

I installed the new Kamikaze. Toggle and Octoprint work very well. Also, the heat works much better. The only problem I see in Redeem - I think that there are problems in the reading cfg files. X and Y axes are reversed and do not move at the defined distance. Changes in printer.cfg not give results. Do any of you install a new Redeem / Kamikaze? What are your experiences?

I tried my hand at a thermocouple today. Turns out it was super simple when using a linear converter. The biggest challenge was adding some more ADC channels to the DT.

I haven't got any parts yet. I prefer to work it all out before buying stuff if possible.

I've never done anything in python so might need a bit of help there.

Update on the bed matrix algorithm: Things are progressing, but I hate it when things don't make sense! Such as getting pretty decent results using a quarter of the bed level matrix... Can anyone help?

Yeah, someone actually did implement something similar to that, but without having the basic stuff nailed down, it difficult to move forward. Looks like the probes distance might be doubled in the current implementation. That would explain a lot!

I've added a login/register button to the forums, so if it works as expected, that might be a better place to post some of the questions that have been posted on this page so far. If you created an account during the checkout, you can use that account, or you can create a new account if you have none.
