M4_SpindleSupport_v3.stp (463.8 KB)
This is the inner sleeve that mounts to the spindle itself.
For the outer sleeve I used the design above in this thread and just cut out some of the plastic to accommodate the large tab on this print.

Sorry to bother you a bit more, but would you mind posting some pictures of your working M4.
I’m particularly interested in where the controller board is.
thanks in advance
Here’s the set up, almost complete. Only the spindle itself is unplugged in this photo, that’s the red and black plug at the bottom middle of the image.
What’s 3D printed here:
- 2 Support Legs (red)
- PCB Mount (red)
- Outer Sleeve (red)
- Inner Sleeve / Spindle Support (yellow)

Looka great!
Would you mind sharing the 3D files to printed for mounting the spindle? including the red parts.
I don’t own a 3D printer so this would save me a great hassle of desining and redesigning until it works…
I am waiting for this: https://www.aliexpress.com/item/1005006318067241.html?spm=a2g0o.order_list.order_list_main.5.3e0e1802Km36Zt
Thanks

Have a look at this thread M4 Router Mounter Be-Gone (use any router with a side entry cord)
Please do scroll through it, because there’s better versions of the supports further down. But you get the context from reading the whole thing
And of course the other files are further back up in this thread

Thanks!
First, thanks very much for the full pic.
Bar posted this in the email update, so perhaps he could provide a page for you to put all the details together with the latest STL files, so that you can update any STL without having to point people to a separate post.
Basically to make this a project on its own. Anyone know how to get Bar’s attention to do this?

Yes, he’s like Kibo that way. (A reference that really dates me.)

I see all the posts 
The long term solution is that we’re working on a new project sharing site to make things exactly like this easy to share and maintain, but that’s not ready yet.
What would be the best way to maintain this in an easy to find and keep up to date way?

I would absolutely enjoy a separate page with instructions of how to assemble and use the spindle with the M4!
For example; I am a bit confused as to how the spindle operates in the M4. Does it get its power from an outlet and has no electrical connection to the M4? Meaning when initiating a cutting program, the spindle needs to be turned on separately?
Also, where do I position the spindle controller/driver?

Adding to that, I am not an EE and have some concerns regarding electrical connectivity, especially to 220V. Anything I shold know regarding powering the spindle? grounding, proper connection to 220V, etc… any electrical safety related instructions would be much appreciated

Yes, with the maslow, the router/spindle has an independent connection to power
and is turned on/off manually, this does not change that
Also, where do I position the spindle controller/driver?
wherever you want that it won’t interfere with the belts 
depending on the driver, you may be able to attach it to the sled but only if
everything is thin enough to be below the arms/belts when they are all the way
down.

If you go right back to the first post in this thread you can see a picture of where, and how, I mounted the PSU for my spindle.
So separate power, and a separate power cord, but so far that arrangement has been working really well for me. In particular it means that the spindle’s speed control is on the side of my frame in a convenient place for me to adjust it.

Thank you both! Will update once I receive all components and complete the assembly.

Did you print the spindle PSU housing or was did you purchase it as is?
I tried different mounting, but now I think this could work best for me as well.
I came up with the design and 3d printed it myself
For the design I focussed on the various points that would be needed to mount the spindle’s PSU and to mount the housing itself to the frame. And then also making sure that the PSU’s connections to mains voltage were not accidentally accessible.
Here is my less eloquent design. If you want something fairly simple. This is on my maslow classic where the bottom outlet is controlled by a relay to control spindle/router power by gcode. The top outlet is hot. The switch kills power to both outlets. And knob is spindle speed.

Very impressive. Didn’t think to power the spindle by gcode. Is that a fairly simple thing to do?
