unfortunately, oiled mechanics like the ball screws of the Onefinity CNC are totally incompatible with wood dust. It mixes with oil and slowly bakes a oil-wood dust mix into the ball screw which will at some point block the machine, as shown here:
Some people protect their Y balls screws with curtains or with plexiglas panes or metal panels as shown here and here. While this can help to prevent large amounts of chips and dust to land on the ball screws, it can never replace a dust collection.
Hi Alex, I have had my Woodworker for almost 2 years now and do not use dust collection while carving. I tried it but didn’t like it. It gets in the way of keeping an eye on the bit and I have found that it just isn’t necessary. However, I keep my shop vac close by and use it when chips and dust pile up that can interfere with the Y rails. After each carve I will manually clean up all the mess. These machines do a good job of sealing out dust and I keep mine lubricated which helps to seal the bearings. Once I followed Onefinity’s recommendation to clean out behind the ball screws white dust wipers. An air hose is also helpful in blowing out any crud that builds up.
I use what Onefinity recommends which is 3 In One lubricant. Also, I have built some 6 inch sides and back to help contain the sawdust. I also use a Wen whole shop filtration unit hanging from the ceiling to keep the air clean in my shop.
as many times as I have seen the picture now, I have wanted to ask you, do you really think that the dust was let through the pores of the 2-micron filter bag? These dust collection systems usually have a fairly simple clamp that holds the dust collection bag in place, and if the 2-micron filter bag has clogged pores and the motor is powerful, then the dust will often find its way out, usually leaking where the dust collection bag is clamped. Or where the 2-micron filter bag is clamped. I remember having seen a video where someone described this.
If available in your area - look at the Harbor Freight 2hp 70gal dust Collection unit. You can’t beat the price point with its CFM’s. . I own 2. One in my shop where I upgraded the fan blade for more CFM’s and one dedicated to my CNC table.
The dust will also affect the controller and cause it to stop working.
You will have to take out the four screws and plow it out with compressed air.
Do not vacuum it, causes static that will ruin the board
