    Default diving into the 3d world.

    My project stems from clients requests to be able to
    1. utilize the additive method to print a model on existing mills using existing electronics and Mach3 control software.
    2. To be able to then, while still on the machine use a spindle to gently machine specific ares of the model on the same machine.
    3. Switch easily from dedicated milling to 3D printing or a combination of the two.


    I started out with a very small 3 axis mill frame that I fitted with ball screws. This little guy can fly at 6,000 mm a min.
    Sourced a extruder to get me started and went to town.
    Made a mount for the extruder. Final design will have the extruder next to the spindle and be quickly and easily removed.
    Wires up a 12 v transformer thru a dimmer switch for the heater element.
    Wires extruder stepper to plug into the controller and calibrated it in mach3.
    Started messing with KISSlicer to do some testing.
    Test prints show promise. I still have to source a heated bed ect. printing on cardboard just does not cut it.

    I have checked out the mach3 plug in for 3D printing. It is great that it runs the slicer on the same machine, but it is not really required. No other changes were made to my mach3 setup other then the steps per and motor tuning for the extruder stepper as the A axis.
    The transformer to heat up the extruder was plugged into the coolant relay on my control box and I insert the Mcode to turn it on and have it shut off at the end of the code.
    The fan on the extruder was wired to the power screw terminals to the break out board in my controller and comes on when the box is powered up.

    I have a digital controller on order for the hot end heater and the heat bed (when I get one) that will regulate their temps instead of using the dimmer switch. This will be a manual set and forget setup with no interaction thru mach3.

    I am currently on hold for parts and filaments but have had alot of fun learning the new terminology and software.

    There is still alot of tweaking to do with this, and my prints so far have been learning how NOT to do it.
    These prints are straight off the printer with no post processing. As I found out, I was running to high of a temp on the hot end and some software settings were in need of a few tweaks.
