Altmill DIY Dust Shoe Questions?

@gmckeown Tks much, George. I need to read up more on how it connects and if it will work with my Mk1 Long Mill. I’m looking for something that does not take away the X travel that my Sienci one does.

Just a note re the Amazon brush stock - the back/spine of the brush is stitch together so bristle loss happens. More importantly, you will see loss where the brush is cut. You will also see a slight gap at that point.
As far as I can tell, McMaster does not sell to individuals in Canada (based on their web site under shipping) …

Yes, the McMaster Carr strips are molded together. You can see in the picture where I got ahold of it with the pliers and pulled several times. It crinked the bristles a little but nothing came apart. Someone else posted they used the 7/32 brush in the original Sienci part, so I thought I could force it. No way, the channel has to be enlarged as its smaller than 7/32.

The parts for the Z mount are for MK2. I had to redraw all of the parts in Fusion 360 due to shortcomings of their design where a number of parts did not fit or were a little too flimsy for my liking . I modified almost all the parts.

I added a back bracket for the hose with magnetic couplers. It keeps the entire assemble quite solid. For me, it works well.

I don’t see an easy way to adapt to the MK1 due to the gantry design.

@gmckeown That’s good to know. Tks, George

With the revised brush holder, the McMaster 7/32 stock fits tight but I wanted that way. Just takes a few minutes of pushing it around in a circle by hand. https://www.thingiverse.com/thing:7008466

The STL files are delivered digitally after purchase. They are not available for free download from what I know.

I just wanted to see if you were willing to share your design for the Altmill Z-mount for the PWNCNC dust shoe. I’m looking to use the shoe, but it would be nicer to have an already designed Z-mount. Thnaks!

I don’t know what a z-mount is but I suspect it’s something similar to PWNCNC’s version 12 dust shoe. I’m working on getting that up and running right now. I’m having to do some small changes to get it to work on the AltMill. Anyway, once it’s up and running I’ll post my build and the spindle adapter I created. Obviously I won’t post anything PnCNC is selling.

Does anyone have an stl for the plastic sleeves that go over the hose clamps? Those are pretty nice and I plan to use for my pwncnc dust shoe.

Anyone looking for an stl of the Sienci sleeve to protect your spindle from the metal circular clamp.

@acruther Do you have a picture of before and after install so I could get a better idea what it does?

These were included with the dust shoe when I got it (August). They were not included in the video Sienci put out regarding the dust shoe and they didn’t release the stls. So I reproduced with an important modification. I found the clamp overlaps and there isn’t enough space within the orginal ones to fit the overlap.
