Adding a CNC Spindle to a CoreXY which specs are the most important I built a CoreXY 3D printer. Print really good, added a small motor for PCB milling, works pretty good for PCB and soft wood.

Get a shop vac with micro particle filter, your lungs will appreciate it in the long run.

The issue is stiffness, so you need a light spindle. Light spindles have limited cutting capacity so you need to go very slow which results in end mills wearing quicker. And the bed isn't really suitable to apply any xyz forces to either. So a lot of resonances will occur. The best way to deal with this is stiffness and mass. A 3d printer is nimble, quick and light, not really suitable for routing. The occasional pcb milling and engraving is what you're looking at.

I've cut plates to build a corexy 3d printer similar to yours using the ox router (see the corexy forum, look for nfan). I'm planning to build a milling machine next which should be able to cut aluminium and other metals better. It'll probably be build with steel tubing and linear guide rails.]]> imqqmi CNC Routers, Mills, and Hybrid RepRapping Sun, 23 Sep 2018 17:14:55 -0400 https://reprap.org/forum/read.php?131,823164,823436#msg-823436 Re: Adding a CNC Spindle to a CoreXY which specs are the most important https://reprap.org/forum/read.php?131,823164,823436#msg-823436 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!

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.]]> o_lampe CNC Routers, Mills, and Hybrid RepRapping Fri, 25 May 2018 03:18:27 -0400 https://reprap.org/forum/read.php?131,823164,823333#msg-823333 Re: Adding a CNC Spindle to a CoreXY which specs are the most important https://reprap.org/forum/read.php?131,823164,823333#msg-823333 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.

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?]]> o_lampe CNC Routers, Mills, and Hybrid RepRapping Thu, 24 May 2018 02:38:20 -0400 https://reprap.org/forum/read.php?131,823164,823164#msg-823164 Adding a CNC Spindle to a CoreXY which specs are the most important https://reprap.org/forum/read.php?131,823164,823164#msg-823164 Print really good, added a small motor for PCB milling, works pretty good for PCB and soft wood.
