I have just received notice that my Smoothie board has shipped. I was order #78. Now we will see that this microbeast can do. Bob
I see the guys are testing it and it looks really smooth Looking forward to what you think of this board Bob I think its going to be a nice one!
This is great @ADarkGerm I found a video of it driving two steppers in parallel an it seems to be doing well.
In all the machines I have built using this method I have never had an issue with feedback , but I agree a separate slave drive would be best. I did find this that may help
We just created a new controller board for CNC applications. The so-called T-Bone is a cape the BeagleBone Black and has a lot of unique features. Here some basic facts: 5 stepper motor driver (run syncronized, 3 x up to 4 A, 2 x up to 1.5 A) 10 inputs for end switches (two for each axis) 3 inputs for incremental encoders (3 axis supporting closed loop control) 3 inputs for thermistors 1-wire interface for digital temp and other sensors 2 high power outputs (for extruder and heatbed, up to 12 A) 1 mid power output (for fans, LEDs, ..., also expandable) Power supply for BeagleBone (5 V, 1.2A) Input voltage 12 - 24 V For more details see our project page: http://tbone.cc We are currently running a crowdfundinhg campaign on Indiegogo to produce the first batch of hardware: http://igg.me/at/t-bone/x/4731310 All hard- and software components of the project will be released as open source.
I think it's great that you can design boards. It's a big problem in CNC right now. Having a realistic, open-source design makes sense. If all the people with the skills to make these would work together, we could all have really great boards. Your funding goal may be too high. I would try for 1000 Euros and 10-20 boards on a first round of funding. I could be wrong but it doesn't seem like there are that many CNC people starting up and buying boards within the time limit indiegogo allows. Some other things to consider(speaking strictly for myself): I'm not a big fan of a steak-shaped PCB. I'm not a big fan of embedded controllers. Just the other day my machine bucked right towards the end of a 6 hour cut. So with my computer I was able to go to the line of code, reposition the machine, and continue the job to completion. There are many more reasons why a complete computer control system is needed. I like the ethernet interface but only so far as it can replace the parallel port. I'm not a big fan of surface-mount boards. Hard to DIY.
Hey Dude, thanks for your comments. It's always good to hear different opinions. With the BeagleBone you have an almost full-sized computer. I think it would be able to run and debug your control software also here. Another DIY approach would be to connect our board directly to the serial port of your PC. You only need a small adapter board with a level shifter. The Arduino is only used for buffering.
since i am a beginner with electronics etc, will just go ahead and ask: would the smoothieboard 5x and this sucker: http://www.omc-stepperonline.com/24...2450vdc-15a45a-256-microstep-m542t-p-293.html ..hooked up to this: http://www.omc-stepperonline.com/hi...motor-113mm-3nm425ozin-23hs454204s-p-127.html ..work together? for powering up the whole contraption, i got three of these: Switching Power Supply 500W 48V 10.4A for CNC Router 115V/230V S-500-48 the printer has four steppers driving four vertical lead screws on which hangs the heated bed, two steppers on y axis driving the x axis and two x axis nema 17 steppers driving the extruder. as for the latter, it's a dual extruder: http://micron3dp.com/collections/al...ll-metal-state-of-the-art-3d-printer-extruder this is what i have been given to work with. i will post some schematics a bit later, have to make them first. thank you so much.
First let me say, I am a total newbie. I just ordered almost all of the items to build a very slightly modified ox. I am looking for a easy to use and learn control board. Any advise would b great.
Hmm missed this one, sorry about that. Well, ( and I may be partial ) but you should take a look at the BlackBox as an all in one powerful and easy to use solution to control your machine.
