In case you missed it, I'm adding a link to the Review Thomas Sanladerer did on Replicape. He loves the hardware, but feels the firmware is lacking. I agree with him and so getting a working Redeem version 1.0 is a big priority now as well as documenting the features available.

Updating the wiki, either thing-printer wiki or the rep-rap wiki would be great!

I hate being the guy to bitch about these things, but the FastBot BBP looks like it is clearly a violation of the CC BY-SA license. I'm using CC BY-SA on Replicape in the hope that anyone who wants to use it will respect the license and keep it CC BY-SA and give credits to the original authors.

Looking through the BOM, the stepper drivers, shift registers, mosfets, mosfet drivers, DAC, EEPROM and the schotky diodes all match. I've not seen the layout yet, but from the picture, it looks like a clean copy-paste.

Having spent most of my time developing this for the better part of three years, it really pisses me off to see something like this. CC BY-SA is super liberal, just add the name of the fucking orignial authors.

While Replicape is not the cheapest product (we are working on that), no way you can combine a Replicape and a BeagleBone Black in a single board  and get the price down to what they are offering. The BOM cost alone will be in the ~$80 range unless you are looking at batches of at least 1000 units, which the $10.000 goal does not match. BeagleBone Black is cheap because it's made in large batches. I'd hate to see people be misled by the promise of a cheap knock off only to get disappointed.

BTW, I love the comments by +Arthur Wolf on their Kickstarter, way to go :)

Sorry, was at MRRF, replicape, the smoothieboard from uberclock, azteeg x5 from panucatt, ramps or Rambo from ultimachine, all good choices.

Working on #debrew 2.0 for #beaglebone week. WIP, but new version will be more stable, better looking, easier to build and have a spoon!

I had the Kossel mini, but was missing a hot end, so I made one! It performs terrible.

I also tried to build my own Hotend but it just got much too hot.

Any chance I could extrapolate this curve for another week +Kickstarter? :) It's been a thriller, but it's too bad to end it on a cliffhanger!

There will be a new revision of Replicape coming out in a few months. One of the most important features is a lower price. Because of that we have decided to sell the remaining replicapes at the price we hope to achieve for the new revision. There are only two left in stock, so be quick if you want to get in on that. Here are the suggested changes for the new revision, but feel free to pile on if there is anything you feel is missing :)

http://www.thing-printer.com/product/replicape/

– Lower audible noise (more and better capacitors + Vref filtering + 4 layer PCB)
– Lower EMI noise, hopefully CE/FCC markings
– Enable pin on PWMs
– Decay mode can be in High Z mode on steppers enabling mixed decay.
– 3-pin end stop connectors instead of 2
– 2-pin thermistor inputs to be more compatible with other electronics.
– Polarity protection on VCC input.
– Two of the end stop inputs can function as 5V servo outputs.
– 15 V tolerable end stop inputs enable the use of inductive sensors without voltage divider.

We are also looking for a cheap and effective solution on programmable slew rate on the power mosfets,
but it looks difficult to get this handled.

The lower price will be possible by opting for a 500 unit batch, using some different component suppliers,
lower margin, a cooperation with a Norwegian company helping with PCB production and logistics, and finally handling
RMA in house (cuts about $20 off the price).

We are hoping to have the Kickstarter live some time in May, add to that 30 days for the campaign and some 45 days for
production and delivery. 
This is the award-winning Replicape!!

In the same vein as my previous post about github and licensing, +Arthur Wolf is patiently trying to get a straight answer about the license. He nails it with:

"Uploading files to github is just uploading files to github, it absolutely does not make your board Open-Hardware. "

And as I said in my previous post, getting your panties in a twist when asked about licensing is the wrong thing to do.

For my next trick I will be using a BeagleBone black in conjunction with some CMOS radar chips to discover two metal pipes with 10 cm separation at a distance of 1 meter.

+Bernard Roth Im using an older version of the dev kits, but with the same chips 6100. SPI for data read out etc. and then a clock distribution chip for the main clock.

The delta algorithm has gotten some much needed love lately and is now working better than ever!
