Adding a CNC Spindle to a CoreXY which specs are the most important

Adding a CNC Spindle to a CoreXY which specs are the most important
May 23, 2018 05:53PM
I built a CoreXY 3D printer.
Print really good, added a small motor for PCB milling, works pretty good for PCB and soft wood.
I want to upgrade for harder wood, aluminum and possibly steel...
I am looking on Aliexpress and I see a wide range of specs and was hoping to find the required wisdom for me to choose the appropriate setup.
ATM, the one that I am considering the most CNC Spindle

Thank you for your assistance

Do you really want to mess up your printer? I have built a CNC mill and it's not even in the same room with my printers.

If you consider buying this spindle, you have to have a battery charged by the 500W power supply. The motor will otherwise cook the PSU.
Also consider the size and weight of it. Can your C-XY gantry handle such weight?

My 3D printer is pretty solid...
I went overboard with the 90 degrees bracket, using an aluminum top plate for the X & Y movement, multiple cross support...

The structure itself is made of 2020 aluminum.

Why are you saying that I would messup my printer?

Debris all over the place. Wood dust sticks everywhere and causes all kinds of issues later. ( even with a dust cover over the spindle and vacuum cleaner )
I even separated my laser engraver/cutter from the printer, because of the dusts.

I knew that I would have to move my electronics from under to the back (avoid the possibility of aluminum causing contact on my board), but I didn't think of that magnitude.

I suppose your PCB and soft wood routing is dustless?
Have to agree with major dust and spoil created by subtractive manufacturing

3D printing little or no force put on extruder --- just sitting there pumping out poly

Milling --- mill produces considerable torque (cutter moving it's way thru material -- some distance away from anchor)

lots of pitch and yaw about Z axis
X and Y have to push much harder

CNC mills beefy to keep tolerances imposed by cutting process
3D printers don't need this

Perhaps CNC mill can 3D print --- but 3D printer milling NOT!
