My suction works well so far but it should work even better with a brush!
It´s been a while since my last log entry. I had a lot of work with different CNC projects. During this time the router had blow out a lot of dust in my workshop. Of course I have a "manual dust suction" with a vacuum cleaner but this works not good enough.
So I decided to upgrade my router with an automatic dust suction which is always available!

If you want to build a desktop sized CNC router, check out this article: http://diyprojectchannel.com/reviews/diy-smart-saw/. There is no need for expensive tools to build this machine.
^^^ $39.00 ^^^ Too many free ones out there IMHO. No need to buy.
Hi Chris, thank you for the hint with the moving-knot ! You're right. The gantry wobbles a bit about the central axis. This looks like great idea and I think i will steal it. ;-)
I have built a couple of similar machines. I like your choice of linear slides. With the bearings so close together on the longest (assuming X) axis, you may experience "racking" of the gantry. I had this issue for a long time and solved it with a moving-knot system and documented it on my website: http://cockrum.net/cnc.html
Your build looks clean - hope it works well for you.
Chris

Great project really I like this idea and also working on it you can see here how we both are working on a similar and unique Ideas.
