    So i found the schematics ect, and have been playing with arduino last couple weeks anyone want to work together to build one off his design?

    So still looking at things, I have an arduino UNO and i am building a list for the things needed to replicate this. I found the files and started to try to understand things first.

    I am not a great electronics guy but leraning the best i can, I got a Ardunio UNO board a few weeks ago and learned the lcd programming ect. It would appear to me that this could be built for around 30 bucks if u actually took the chip off the board. I almost hit the buy button on a superpid last week and i am kinda looking forward toa project. But of course buying a proven, highly acclaimed product like a superpid would be more beneficial. But then again i built my cnc out of roller blade bearing and bike chain. So perhaps a DIY router congrol should eb attempted. I will get a parts list done tongight from what i see on the youtube videos and the files.

    Hoping someone will jump on board wiht me . But if not i will document the best i can

    Hello Tim
    not sure how much I can contribute, but happy to ride along
    I have quite a bit of 'duino experience, but not mush with the PID algorithm
    I get the theory, but have yet to build a working example

    until now maybe!

    cheers

    great mike, well i am new to arduino, i code mostly in c# and thats all self taught, so perhaps we can work off eachother. It appears he posted the arduino code. so the main thing would be just building the pcb.

    I plan for now to use 1/16 plexiglass with drilled holes on my cnc then connet the backside with wire. Since this si my first circuit other then test ones thats my route for now.

    I am now getting my printer situated so i can print all the documentation he posted earlier. All the credit goes to the guy who started this thread. I have to relook at the name to thank him correctly.

    I will get a parts list and how i beleive the circuit works although i am not an electronics expert but hopefully together we can put a good DIY on here for others to learn.

    Also as a sidenote my plan is to try to get this to work and if it does then also make a dual,

    same board will do my speed controls, and also do my extruder heating and heatbed control.

    i have really been wanting to do a head for 3d printing on my machine. but theat the next step

    i uploaded the daigrams i found, again thanks goes to the original thread starter. I assume that in the diagram a 390 saying R14 is a 390 ohm resistor. I am building a parts list now

    Straga,
    Я надеюсь, что вы можете помочь нам дальше с проектом. Я уверен, что с языковым барьером трудно помочь иногда. Я ценю вас этот обмен с сообществом ЧПУ. Я надеюсь, что если мы столкнуться с проблемами, вы будете так любезны помочь. еще раз спасибо

    Тим

    i am thinking the one he had that was not under "old"

    I am curious do you use skype? it be great to be able to free chat some while working on the concept my skype is timmyb46 for anyone interested

    I just started hacking apart random electronis around my basement that i have been thinking of taking to the dump. found an ancient pc gonna see what peices i can find in there. This might turn into quite the fun project

    I just found the same circuit!
    just converting it to EAGLE so we can do something useful with it

    sweet i know eagle is apparently the pcb software. rememebr i am new to this. I am running to radioshack to see what parts they may or may not have there. I got a protosheild in my arduino on top and am starting to layout the stuff

    Again in case u missed it above i am on skype if at some point u want to type back and forth live. I am trying to understand the two different kinds of triacs used. where did u find the schematic? is it a different site? for now i am just gonna breadboard it up then solder i beleive. let me know what your plan is. we can work together going forward.

    i also see he used a pickup with a magnet for rpm. I am thinking a IR diode version if u know what i mean

    I got the schematic from the githup zip files, same one as you posted the picture for
    still working on the triacs - not sure why there's two!
    one ought to be enough

    I am expecting to use an IR LED/sensor for the speed pickup

    GREAT!!! that was my plan also. Im heading to the shack although i doubt they will have anything. The specs from digikey looked the same to me on the triacs. Maybe he used what he could find around his place. I will be back later. I work this week so was hoping to get some progress done tonight enought to keep me excited lol

    see ya in a bit

    I have the code open in one hand and schematic in the other
    helps to know what the code is trying to do with the hardware and vice versa!

    I think we can swap hall effect and IR quite easily as long as we get a solid signal from either

    looking at the circuit again I think there's only one triac U12

    U41 is an opto isolator - part of the zero crossing detection using a 12 volt signal derived from the mains supply

    U11 is another opto-isolator to drive the triac

    hope that all makes sense

    good shopping
    cheers

    Ok I got all resistors. I have to learn more about the triac. I will post my concept of what's going on later. I could not find the opto. Or the right bridge rectifier at RadioShack. I'm gonna order tomorrow the rest. If u think I shld order anything different let me know. I'm kinda. Electronics newb so hope I don't hinder u to much mike. Hoping to be using it by this weekend.

    Thanks

    Tim
