Yeah, I’m fairly new to CNC, so I’ll be experimenting with different tools and settings for a while 
I’ve used a 2mm bit diameter, with a 1mm depth per pass and a feed rate of 900mm/min. The figure in the image above took 95 minutes to cut from a 9mm plywood sheet.
Today, I’ll be testing a 4mm single-flute bit, aiming to double the feed rate.
I would suggest you print a proper fan for your spindle. The stock one doesn’t push much air. You can find them on thingiverse
This looks awesome! Thanks for sharing!
How is the noise level? I think that’s a huge selling point of the spindles
New clamp wedge design. Remember to set a pause in your 3D printer at the layer height at the top of the captive nut. And as soon as your printer hits that pause layer get the captive nuts in pronto - it’s easier when the plastic is hot, and you’ll get better layer adhesion when you continue printing.

The PCB mount that I had first printed in PLA, didn’t survive some abuse I was throwing at it, specifically when I lifted up the top clamp with the entire spindle assembling in by holding onto the PCB. It’s still holding together, but barely.
So, I’m reprinting in PETG.
And if you’ve already printed yours in PLA? Don’t worry about, just don’t do what I did.
@TimS,
Thanks, this is on my to-do list.
That said, even with the stock fan and minimal clearance (about 5mm) between the PCB and spindle, the spindle barely feels warm after 3+ hours of continuous operation at max RPM.
@bar,
The spindle itself is very quiet - much quieter than my shop vac, most of the noise comes from cutting and vibrations resonating in the plywood. I haven’t run Maslow with my Makita router, so a direct comparison wouldn’t be fair. However, comparing the Makita’s noise (cutting 6.5mm in a single pass by hand) to the spindle (cutting 2mm per pass), the difference is significant.
just tried assemling a new 4.1 with this tonight, I think it needs to be thinned out just a hair, and it would be nice if the notch in the sleeve had flanges on it to hook into the thumb notch, so that it can be assembled and stay in place when the inner part is getting ready to be used.
I would also consider making it solid at one end, so that one of the maslow clamps can be tightened down around it to make the maslow solid with it installed, but the spindle removed.
Used @m8n’s sleeve file with some modifications. I had to abandon the outer/inner sleeve approach and go with a single sleeve instead, as the inner sleeve walls would have been too thin. I also adjusted the sitting depth.
I bought the same spindle as you and it’s currently in transit.
Would you mind sharing the modified .stp file for the inner sleeve if it’s working well?
Any other insights since purchase on this spindle? Cheers
@md8n did you have any reason for not adding a knob on the outer sleeve like the one on the inner one to restrict its position and prevent it from rotating? I was thinking of using the bottom socket for that, but I don’t want to break something. for now the router in/out is a bit awkward.
To start with it was just the outer sleeve with a lip on the top edge so that it wouldn’t slide down.
Figuring out the problem with rotation came later.
So yeah, feel free to make changes to the model
