Build log: 800W Chinese spindle for Shapeoko 3

Postby Estlcam » Wed Dec 09, 2015 9:51 am

Hi everyone,

the mailman just dropped a little parcel with a 0.8kW spindle and VFD for my new Shapeoko 3 :D

Parts:
  • Spindle mount
  • 1.5kW VFD
  • 0.8kW watercooled spindle with some ER11 collets in front
  • Line filter

I still need to buy a few parts like a small water pump for cooling but for now I'll just start assembling the things I already have.

So let's start with the spindle mount:

The one I got looks nice and very very sturdy but also a little heavy @ 725g / 1.6lbs...
I'll try to cut it down into 2 much smaller and lighter clamps with a hacksaw and then turn it flat on a lathe - wish me some luck... :?

Thanks for posting the build Christian. I literally had my finger on the button ready to buy one of these yesterday but hesitated. I'm interested to see how the wiring goes. Do you have a link to the one you bought?

I'm now out of the blue being plagued with disconnects after running for over a month with no issues. Thinking having a quiet spindle and getting rid of the disconnects from the router will be worth it.

Hi,

Mine is from a local German shop: http://www.rc-letmathe.de/
It is basically the same spindle / VFD set you can buy directly from China on eBay but with a better connector including a ground pin.
If you like to buy a spindle make sure it matches your countries line voltage - I'm from Germany so I have the 220V version but in the US you'll need the 110V version.

Have a look at your grounding wires.
Make sure everything is grounded and try to achieve "star" grounding so all ground wires meet at a central grounding connection instead of "chaining" them from device A over to device B and so on...

just wired the line filter, VFD and spindle...
All a bit makeshift at the moment but works very well so far :D

At the moment the spindle can be controlled from the VFDs control panel - next I'll try to hook it up to the carbide motion board so it can be controlled by the computer...

So some cable management first:

Also slipped some heat shrink tubing over the Y motor cables to protect them from the shrouds sharp edges:

And finally tied down the USB cable so it won't wobble around or even unplug when the gantry moves:

Cable Managment

WOW! Well done. I have been thinking of cleaning up my wiring too. Is that split wire loom? Can you recommend a vendor?
Opps, I see you are in Germany, I will find a local source.

its cheap corrugated tube from the local hardware store - costs less than a dollar.
I've used the non-split version - I needed to remove the motor cable connectors anyways for the heat shrink tubing and they are easy to remove and reinstall.
(each contact has a small barb accessible by a small rectangular window - just press it down with a little screwdriver then pull the wire out)
