My new 3D printer

Postby jknightandkarr » 2016-Feb-Tue-11-Feb

Well while I don't have too much detail on it, I have started thinking about parts for my new 3D printer.
Details:
1) Either 12"x12"x12" or 24"×24"×24" print size.
2) The Kraken 4 nozzle water cooled bowden style 1.75 mm extruder.

3)Arduino Due, R.A.D.D.S. controlboard+ extension, and RARAPS128 drivers.

http://doku.radds.org/dokumentation/extension-board/
http://doku.radds.org/dokumentation/raps128/
4) The heated bed will be stationary and the X, Y, & Z axis will move.
-Thinking of using heating pad to make the heater for print bed.
-Have a book on building a cnc machine, so using that general design and modifying it to. https://buildyourcnc.com/Book.aspx

This is main details now but no doubt more to come.

Checkout the "duet" with reprapfirmware, the duet has an ethernet port, which has a web based management console for the printer, so its effectivly got the equivalent to octoprint built in.

I didn't see that one. Will check it out, though the web based printing i dont need. Lol mainly no smart phone with data anymore. Lol Thanks.

I have a question on the micro stepping. Does it mean it takes the signals for the motor n divids it by whatever. Setting like 1/16 or 1/128? I dont quite understand this.

RepRapPro has shut down (which is a shame, Adrian Bower deserved some return from starting the RepRap movement that made a number of other people rich, some new TV stars, and paid for at least one Mexican Villa), so even with DC42's support it's possible the firmware's future will become questionable.

You could also take a look at the Smoothieboard. I haven't been following it's ethernet support, but they claim a web interface.

I recently bought an RPi 2 to run the controller software for my Ubiquiti equipment (that's another show, The controller's not necessary for day to day use, but I'm a network geek...), and for grins threw Apache and MRTG on it. No plans for octoprint (which would be on another Pi, anyway). The original RPi (mine came in the second wave, couldn't get through to order one on opening day) was a bit of a disappointment, too sloe (pre hard float) for me, but #2 is a comparitive screamer.

I spent $62 on the tasty Pi, 32GB high speed Evo SD card,case and PS (next time I'll use an old phone charger and print a case...), but that's getting within spitting distance of one of the new cheap Intel mini-boxes. Remote desktop into it and run Repetier-Host (or that other thing). Might be a viable alternative. Of course, it's never a good idea to leave the printer running unattended for any length, even if you're already friendly with your local fire department and EMS. Have them over for coffee and cookies instead of a bonfire.

Ok, on microstepping. Whats the best way to use it?? The Duet has 1/16 micro stepping, and the RADDS is 1/128. Will either one work or is the 1/128 not gonna work well. I am not worried about etherenet at all, so that's not a concideration at all.

I checked that smoothieboard and it is 3-5 stepper motors, useful in a possibly useful in another project, but for this project I need atleast 3 for the X, Y & Z & 4 extruder, so either the RADDS or the Duet. I like the Duet cause it looks like the Arduino Due is built in, but the RADDS has the 1/128 micro step.

I am using one of my old RPi Model B (i.e. not the newer RPi 2) with OctoPrint. It isn't super fast but it runs OctoPrint very reliably. There is no reason to replace it with a RPi2 (I have one of those as well).

1/128 microstepping is overkill, way more than you need. Use 16.

However, once you get it to work experiment and see what happens. You will not gain any accuracy with higher microstep numbers (the combined 5% tolerance on full steps and whatever on microsteps makes them not terribly accurate), but you might gain reduced motor noise and smoother operation as the steppers move in smaller jumps, at the expense of greater processor use on the microcontroller. Eventually you'll hit a step rate limit, but it should be a lot higher than Marlin's 15K or so. If you go this route report back on what you find.

Spend some time googling "kraken extruder controller", got a number of hits some of which looked useful.

I'll keep that in mind for my only RPi B. No downside to using 2's here.

BTW, I haven't given up on AngelScript, CSB, there's just a conspiracy to eat up all my free time. Moving all this white stuff around, and fixing what that task breaks, is not helping. 107"/2.7m last time I looked, less than most years, but now trying hard to catch up. It would be OK if it just stayed shoveled :)

I have 3 RPi B. One is running OctoPrint, one is serving as a weather camera and the third is for building stuff for the others. My only problem with my RPi2 is I have not figured out what to use it for yet :D

Re AngelScript CSG, take your time. Peace of mind + inspiration is good for such things. The white stuff has come "ready shoveled" here recently, a good thing since the blower has broken down. However, there are other time thieves...

@cacb, sorry about CSB vs CSG. Whoops. My blower isn't blown, but a connecting pin fell out of the tractor's 3 point hitch attachment. Cobbled back together, and the materials to make replacement pins (too much load to 3D print them, think thousands of pounds on 7/8 pin) is ordered.

Sorry for hijacking your topic, jknighandcarr.
