BeBoPr++ (also BeBoPr / BeBoPr-Bridge / BeBoPr+)
The first real, shipping board for controlling a 3D printer with your BeagleBone. These boards are known to work with LinuxCNC and the MachineKit images, and several people (including me) are using this board to control real machines.

Where to buy: The BeBoPr++ is available directly from the designer (email for details). The original version (usable on a BeagleBone Black if you obtain a Bridge board) may still be available from some of the following vendors: If you do not buy your board directly from the designer, you will not get any connectors and you will get the original board designed for the BeagleBone White. You will need to purchase at least two power connectors to get the board working. Also, if you have a BeagleBone Black and would like to use the HDMI port, you need a Bridge Board, which you can make yourself or I am selling boards pretty much at cost so you can avoid the 2+ week wait from OSH Park.

More information: A design by Charles Steinkuehler (your friendly blog host!) converting the RAMPS-FD into a BeagleBone Cape. This is intended to address what I see as shortcomings with the currently available capes. Several CNC breakout boards are available at reasonable prices, but they don't easily support 3D printers (no heater outputs or Pololu sockets). The available capes that target 3D printing (BeBoPr and Replicape) are excellent designs, but both are complex and expensive. The RAMPS and RAMPS-FD designs are simple, functional, and inexpensive. I hope to keep that combination with the Cape version. Where to buy: PCB Design is available from OSH Park Assembled boards are available from Pico Systems |

CapeR
UPDATE: This design is currently deprecated. It looks like the market is fixing the need for CNC capes without my help, and I currently feel making a Cape version of the RAMPS-FD (see CRAMPS, above) is a better way to go than crafting an interface board to an existing RAMPS.A hypothetical design by Charles Steinkuehler (your friendly blog host!) intended to address several issues:
- Interface to a RAMPS board (this may be unnecessary, if the Rosetta Bone becomes available)
- Allow use of AM335x hardware encoder (primarily for use as a spindle encoder with a step/dir driven machine)
- Optimize the pinout to allow PRU direct inputs to be used for soft encoder inputs (for a true servo system with minimal extra hardware)
- Optimize the pinout to allow PRU emulation of an EPP port (or possibly use the GPMC interface and a tweaked FPGA configuration), allowing use of "smart" off-board controllers, like the Mesa 7I43 or 7I90 for true servo support with no performance restrictions
So far, this board is not past the planning stages, although a lot of work and thought has gone into the choice of pins for the I/O. Note that if you are not trying to do encoder inputs or support EPP communications, the pin assignment for step/dir, limit switches, and the like is pretty much arbitrary. The PRU and HAL code can read and write any available GPIO pins as readily as any other. I'll work up a blog post about BeagleBone pinouts for motion control...in the mean time, if you're working on something and want my view on I/O assignments, just send me an e-mail.

There is nothing for the BeagleBone that works with true servos (yet). That is what I would like to see designed, or will do with the CapeR board if no one else beats me to it.

Here's one for controlling motors for a robot (or other purposes - controlling a robot is what I'm planning on using it for).
ReplyDeletehttp://exadler.myshopify.com/products/dual-motor-controller-cape-dmcc-mk-6
That looks like a nifty little board, but I'm not sure it can be made to work with LinuxCNC. Do you know where to find any specifications or design files? Looking through the driver software, it looks like it's controlled via I2C with updates every 200 mS, which will be too slow to do coordinated CNC (at any sort of reasonable speed).
DeleteI'm the creator of the board. You can find the full schematics and PCB layout on https://github.com/Exadler/DualMotorControlCape. The software can be found at https://github.com/Exadler/DMCC_Library. You are correct that it is controlled by I2C, and I'll actually be trying really soon now to get it working with LinuxCNC - I'm trying to CNC convert my 7x10 mini Lathe to CNC, so I'll be diving into the Linux CNC issues and testing the update speeds. I can't promise anything, other than I'll find a way to get it working and details/results will be in my blog at http://exadler.blogspot.com
DeleteThanks for the details Paul! I've added them to the board entry. Let me know if you get it working with LinuxCNC, or if you need help with the HAL driver, and feel free to email me directly with questions.
DeleteThanks for the offer to help! I'll probably take you up on the HAL a little later after I get going on the LinuxCNC!
DeleteNot to knock on Xylotex but there are $100 drivers (massmind TB drivers) that blow them totally out of the water. I had one of them and with my new drivers I'm getting WAY faster and better results with no stalling.
ReplyDeleteSo I have a question past my little quip about Xylotex :)
I just buy a cape and a Beagle Bone black then I'm set?
MY LinuxCNC machine is old and is starting to glitch.
So far it's wreaked $45-$100 of wood (depending on supply) and I'm getting mad.
Two years of playing around and I'm over the bulky old computers.

"I just buy a cape and a Beagle Bone black then I'm set?"
DeleteLinuxCNC and my MachineKit image are working well, but anyone using it at this point is definitely an early adopter. If you are looking at using one of the CNC style capes with a DB25, it will PROBABLY work with the MachineKit image with minor tweaking. Most of them are based on the same pinout used by the BeBoPr-Bridge. If you are familiar with LinuxCNC and it's ini and hal files, you shouldn't have too much trouble.
Of course, you do also need the other bits for a full system: Power supply, stepper drivers, eStop chain, an actual mill or router, HDMI monitor, keyboard, etc. Just a BeagleBone Black and a cape won't do much completely on their own! :)

Hi Charles,
ReplyDeleteJeff from Xylotex here. Just to let you know that my BBB_DB25 boards is available (and has been for a while).
Thanks,
Jeff
Great news, Jeff! I'll get the page updated.
ReplyDeleteCharles, the Replicape is now available for sale in case you want to update your overview page. Go ahead and grab the picture as well if you want : ) http://www.thing-printer.com/product/replicape/
ReplyDeleteThanks for the ping, Elias! I had gotten halfway through updating the list when I got sidetracked and forgot to finish. I've re-organized a bit, and updated the Replicape entry. Let me know if I made any goofs.
DeleteLooks good, Charles! I'm eager to see how it performs with a LinuxCNC image. As you may know I'm working on an alternative implementation that uses the PRUs instead, but if LinuxCNC turns out to work better, that might become the standard software.i If I have your blessing, of course..
DeleteLinuxCNC is fairly "heavy", but shines in setups running closed loop or with complex kinematics. For a typical 3D printer with steppers and trivial kinematics it probably doesn't matter too much. Even linear delta machines have "simple" kinematics (no trig functions).
DeleteYou are, of course, welcome to use LinuxCNC and any of my work you find useful. Let me know if you need help trying anything out.
Charles, the BeBoPr++ is now available for sale (and shipping). I've started a new repository on github for the BeBoPr++: https://github.com/modmaker/BeBoPr-plus-plus . The only real thing there now is the downloadable manual.
ReplyDeleteGreat news Bas!
DeleteCongratulations!!! ...and let us all know how we can buy one!
we just about to launch a new CNC controller board for the BeagleBone. Check out our project page on tbone.cc or our Indiegogo camapign at http://igg.me/at/t-bone/x/4731310
ReplyDeleteAre all 6 of the CRAMPS steppers driven from the PRUs? Wondering if it would be suited to drive all legs in parallel of a hexapod.
ReplyDeleteYes, all 6 steppers are driven by the PRU. The PRU code can be configured to drive an arbitrary number of step/dir channels, limited mostly by available I/O pins and somewhat by execution time (maximum desired step rate).
DeleteHi Charles,
ReplyDeleteThere is available a PMDX cape:

ReplyDeleteHi Charles,
ReplyDeleteI was thinking to develop 3 axes machine wood mill using CRAMPS available with PICO-Systems.
My question is I alredy have stepper motors of 5 amps rated.How can I connect them to CRAMPS board .I do have stepper drivers but not POLOLU Style .
Please see the "Support" link at the top of the page.
DeleteThe CRAMPS board is not really setup to drive off-board stepper drivers. The step and direction lines are directly driven by the BBB, which doesn't really have enough current capability to drive the opto-isolaters typically used for stand-alone stepper driver inputs.
That said, you could fairly easily make a Pololu-sized board with some 'HCT buffers (or similar) that would drive the step/dir/enable lines (plus ground) to the 4-pin stepper motor connector. You could then wire your stand-alone drivers to the stepper headers.
Or you could use one of the capes that has DB25 connectors and a standard parallel-port breakout board to connect to your stand-alone drivers.
Hello Charles. Could You tell me what exactly I needed to build my own 3d printer or cnc milling machine based on BeBoPr++. Where to buy BeBoPr++ ?
DeleteGreetings.
In addition to the BeBoPr++, you will need stepper drivers (Pololu style or outboard) and the rest of the CNC Machine/3D-Printer.
DeleteSadly, I recently learned that Bas Laarhoven has passed away, and the only way I know of to get boards is directly from him. You may be able to find an original BeBoPr board built by Circuitco in stock somewhere, but I have no idea if or when new BeBoPr++ boards will be available. :(
Is it absolutely necessary to use the bridge BeBoPr, or I can simply connect BeBoPr circuit via wires to the BeableBone Black?
DeleteGreetings for all NewYear:)
You can manually rewire the signals, but it's easier if you use the bridge board with the (original) BeBoPr. Alternately, if you don't need to use the eMMC and/or HDMI, you can rewire a limited number of signals (or use the BeBoPr as-is if you can forgo both the eMMC and HDMI interfaces on the BBB).
DeleteThere is an other one available at http://halaser.eu/e1701p.php
ReplyDeleteNot only a cape but a full BBB-based controller for CNC axes plus laser control.
I am happy to announce Furaday Cape v1.2 is available now!
ReplyDeleteNow all 8 Digital Inputs are ready to use.
Please update the number of DI and add 4 separate optocoupler outputs. Thanks!
Great news! I updated the entry, please review and let me know if you need any changes.
Deletehello everyone! we are looking for a few good beta testers for our new beagle bone based CNC control breakout board for mills,lathe, router and other specialty machines. requirements are that the beta tester has good computer,electrical and communication skills and machine ready to install the new control system onto and the time to devote to the project start to finish in a timely manner. we will supply breakout board, power supply, basic cables and unlimited tech support in return for product feedback, photos, videos of your machine. if you are interested send me details at cnckeith@gmail.com
ReplyDeleteIs anyone still updating this page? Nothing with a parallel port still exists and I need one for my g540
ReplyDeleteI still do updates, but there hasn't been any news for a while. The DB25 capes never really took off in production, so tend to be hard to find. You can wire something up pretty easily with a BBB prototype cape, all you really need is a couple TTL style buffer chips to get a bit more drive and protect the BBB I/O pins.
