This is my 3Dprinter I built last year, but always had problem with the open source software. I have a Sherline cnc and want to run my 3d printer.
I found a great way to convert any cnc into a 3d printer with just a few changes.

Hi Tommy.
I have a 2-year old Ultimaker to which we are adding a hot bed.
My experience is 40 years in the cnc controller field.
Are you using Mach3 now?
I have some ideas that we can discuss re 3d printers (including building a uv resin with full color capabilities).

hi, memoryman,
is Mach3 open source software?.. , i still don't understand how this software can adopts/hook PC timing easily.

Hi Bill,
I am not running mack 3, but would work just fine. The Sherline CNC came with Qcad and other cheap software.
In fact I do use Mack 3 on my pc (windows 7) and transfer the gcode to the Sherline using memory sim.
I also have been looking into using composites like clay, fiber class and types of resin, even wood fibers with other type of materials.
I also think laser would work just fine for metals.
I also like the idea of using UV composites for fast drying effects, there could be something to it.
I think in the next 10 years, we might just print our own flat screen TV's, or any Electronics gadgets.
Just think we would just order the software to print a (i pod) or a electronic part for our car. These are the possibilities of a 3D printer.

The microcontrollers have to take care of the real time positioning work. The host software takes care of slicing the 3D structure into layers and calculating the motion that the microcontrollers then execute.

One thing to remember is the extruder does not need to stop the feed of PLA or ABS while running, infact most cnc driver could turn it off/on by the mill motor control.
This also means that you could add a special extruder/ hot tip to any cnc and just reverse the z axis to move upward after each pass.
Anyone could see that using a CNC as a mill could easily convert it to a 3D Printer as I explain in my video.
I still have to work on the extruder driver and heated tip software that is a separate item, not a problem when I did it last year on the SmartScareCrow Show.

I also post as nge-pro.
No, Mach3 is a commercial product for low-end cnc machines US$175.00/license + US$50.00 for add-ons.
I am most familiar with Fanuc products, but have worked with Delta Tau hardware and software.
My financial situation does not permit me to do much experimentation at this time, but I can still discuss.

Financial situation is hard on most of us, even I cut corners to save a dime or two. This is why I keep increasing my knowledge to save dollars.
As someone that did mechanics on all type of engines for many years, every time I work on any engine of my own, it's like getting paid and not putting a dime out for labor.
No different in technology, anyone could do it in a cheap way and still be good enough to get the job done.
I always have this opinion that our limits are what we are willing to learn. Even when I did mechanical engineering in school I could not finish because of how they want you to think.
But this did not stop my studies in mechanical/electrical engineering. My point is knowledge is power, money is just a tool. I believe I can build just about anything I want, I would just need to do enough research to get it done.

No markE,
mach3 didn't use any micro-controller, all outside PC is just motor driver( without MC ) and censors, no MC is necessary, computing and real time timing for position is done by this software. amazing stuff of this software is it has "window-driver" can hook interrupt 0.
LoL, i got you this time.
...
-
"and censors," we have too many 'censors' already; surely you meant SENSORS?
-
I designed a very low cost absolute scale specifically for low to medium cost cnc mills. It eliminates the homing and overtravel hardware/software costs.
Also added some unique features, but lack of resources means the design is shelved.
However I am willing to contribute my time and knowledge.
Bill
-
"and censors," we have too many 'censors' already; surely you meant SENSORS?
Yes, SENSORS is better or input signal. :)
...
"but lack of resources means the design is shelved" , you meant your design is censored ? just kidding.
-
MiB censor everything I say and do; they even look at my shelving... :)
-
Well, nothing we can do about that. lol

Yes you did. How did someone manage to hook interrupt zero in a Windows machine?

A couple of years ago I converted one of my CNC machines to a 3D printer and posted the step by step on my forums.
Your welcome to check it out.
http://www.ukcnc.info/forums/forumdisplay.php?8-RouterStrap-3D-printer-using-your-own-CNC-machine
Was a good way to get to grips with 3D printing and what is involved. Software/firmware has moved on a bit since then though.
You soon realise that converting a CNC machine can work, but so slow and noisy using ball screws. You will soon want to move onto rapid movements using belts.
Then moved onto dedicated prototype printer but using commercial linear components.
http://www.ukcnc.info/forums/dprinter.php
We use this prototype daily for printing stepper covers etc etc.
This year we are going to release a more compact design 3D printer and also a Scara Arm 3D Printer which is cool to watch.

AFAIR. the only way, he must deal with very ugly language, needs about 5-10 minutes each time to compile and test that driver (win-driver), also single space unseen from text editor can cause blue screen. "Windows Driver Kit" is free download from windows to experiment with it. there is a tool included in WDK where we can see how many int0 fired in seconds, normally, it fires at 100 hz or 1khz, while when mach3 was running ,we would see 25khz or 30khz. i read about real time OS which maybe provide exclusive access to real time timing but never try it.
-
My cnc is running on the Lenux system, I believe it's better then Mach3 on windows.
I would not have a problem with 3D printing.

Windows goes off with long delays so often and easily that it's pretty rough to do anything with it that can't tolerate multiple seconds of latency at least now and again. You are a lot better off with any version of Linux. There are real-time Linux distributions out there that can make Linux pretty tight.
-
Because Windows is not a deterministic system, Delta Tau and others use a separate processor on their motion control products. Windows is used as a HMI only.
I have Linux cnc installed but not used it.
There was a 'PC' based cnc by MDSI (bought up by Tecumseh) but it was more expensive than Delta Tau, Galil and similar companies.
ASAIK, Mach3 is a fine product for all but high end machines.

This is my experimental extruder/temperature controller.

This is a update on my 3D Printer extruder/heater controller test run:
https://www.youtube.com/watch?v=xGCb4drbBM4 (https://www.youtube.com/watch?v=xGCb4drbBM4)
I have to update my heating tip, this was a 4mm tip from a 1/4 bolt.
I have brass I can machine and 3mm drill bit.

This is my extruder super high temperature tip design for plastic or liquid metal.

Hi Tommey. I like the idea of using a sparkplug. Did you say that drilled the hole 6 mm or .6 mm? I use .16 mm in my (used a carbide pcb bit); how well would that drill?
-
I had a .6mm from my last tip, now it's .4mm.
Thanks...
-
Of course I screwed up; meant 0.4 mm, .016".
-
I think you could drill that small, but also it may put a load on the feed and just jam up.

Has not been an issue with my Ultimaker.
