    Very nice conversion. I want to inform you and other makers about a web page who are selling CNC to 3D printer conversion electronics. All the controllers are open source. There are also stepper motor controllers. As you mentioned in your post the temperature control is very important for getting nice results. The PID controller on the market are not optimized for extruder temperature control. They are specially for industrial control of large masses. Anyway these controllers here may help you.

    I’m heading down the same path and adding a 3d head to my cnc. Do you have a recommended parts list?

    • Hi, good project 🙂 I don’t know of any ready to go setups, but there may be something out there if you look. For a hot end I really like the E3D hotend, it’s all metal and can do nylon type high temp materials which is nice. For a temperature controller you could use a PID temperature process controller from eBay or something and replace the thermistor on the E3D end with a thermocouple instead. Mounts and stuff would have to be custom made and you’ll need a filament drive mechanism as well. Try checking out some forum sites like CNCzone.com and reprap.org for more ideas. Good luck with your project.

        Thanks for the feedback. Not looking for a kit, my entire system is custom, so I’m looking to cherry pick al the parts.

        I’ve got my initial list built, but the filament drive mechanism is escaping me, any recommendations? Something that will work with the E3D? I already have a nema 17 to run it.

    An interesting project for the winter.
    On my minimill and minilathe conversions, a ramp up to speed is required. I guess this would not work too well with a printer,it would cause unevenness?

    Do you sell this printer?
    What is the largest object size that can be print?
    May we use cnc work/function , after convertion into 3d printer?
    Could it be suit to 5 axis cnc function for milling foam, wood ,stone and even metal?
    I ask to send answer to my mail.

    There is a special controller board optimized for 3d printer temperature controller. Take a look at the web page

    Did you have any particular challenges with the PID tempature controller configuration? Are you using a thermocouple? I was looking at doing a similar conversion, and had been searching eBay for PID controllers to use for a heated bed and extruder, wondering if you would recommend any particular PID controller?

    • The cheap chinese temp controller I was using was waaay off on the temps it was reading which I think was causing a lot of problems. I’ve since gone to a standalone 3D printer which uses thermistors and a RAMPS controller, however I did buy a Watlow 96 PID controller on eBay to replace the junk one. I’ve used a Watlow 96 before on my copper vapor laser project and it works well and reads right.

    Good conversion but I have to ask if the whistle actually work?

    • The small whistle worked, the big whistle actually lets too much air out of the sides to work (it’s not water tight) and if I cover the sides with my hands it just barely whistles. I’m sure if I upped the extrusions value and had more solid fill it would work fine.
