New dust foot

Hi,

Whit new machine I made much more Plywood, MDF and dust board cutting. There is a lot of dust and chips flying around. In whole room there was mess. So "dust foot" was a must have thing.
I had to remove Z axis from machine.

On the bottom of it I drilled 4 holes and taped them M4.

 From 4 mm Aluminum plate I cut holder and screw it to Z axis. This will be permanently installed on machine. Additional hole is for my vacuum hose.

Vacuum table

Hi,

Sometimes friends ask me if I will cut off the PCB on my CNC. So I use double-sided tape to hold laminate on table. But this is not good way. Only THT elements could be cut like that. Sometimes it loos grip, it is hard to do 2 layer PCB. The most problematic thing for me is to use engraving cutter and not destroy it. I have in my workshop 2 vacuum pumps.

So I can use them. Conclusion is clear - to build vacuum table. I check internet for some examples and I made first trial to build it.

CNC - table

Hi,

As work with machine are blocked I decide to build table for it. Most of parts that was used are free, that I found or get form someone.
BOM:
- small rack used to transport servers
- two big logs ow wood, and some other wood parts
- 4 legs with M12 screw and  long nuts for it.
- 4 castors
- Plywood for top.
- nut and screws

T-nuts for 45x45 aluminum profiles.

Hi all,

last days I bought some second hand 45 x 45 aluminum profiles. I will build with them new CNC. To connect rails to them I have to use M5 screw. Normal metric nuts are to small, because profiles have 10 mm grove. I checked web and there were some special nut for this. But the prize is so big. For 30 nuts I have to pay more than for 4 m second hand profile. So I decide to made myself one. I measured the T grove in profile, took 20 x 5 mm flat and put it on CNC. And this is what I have:

 

T shape of this nut holder made it easy to slide inside a grove. Used normal M5 nut made it durability. It can be easy changed to bigger nuts. To compare some old special nut. Prize of it is equal to prize of this 3 that I made.

Cyclone

Hi all,

I decided to build something that should be build long time ago - cyclone. Paper bags to my workshop  vacuum are incredible expensive. This is why I decided to used some plastic pipes (100 mm and 150 mm diameter)  and bucket, use some MDF and silicone for sealing everything. This is how it goes:

Chips & dust

Hi all,

Everyone that have CNC have two problems chips&dust and noise. I do not like to have mess in my workshop so I decide to solve first problem somehow. First of all chips. When I cut Aluminum chips are flying everywhere, so I made barrier for them. On the side of the table I have mounted 4 mm Plywood and I do not remove it. In front and back of table I mount 6 holders. When I can install and remove 3 mm MDF sheet. This is how it looks like:

T-table part 2.

Hi,

yesterday I try my new table. It works great. There is no problem with attaching different type of materials. Also I made some additional holders, and corner finder for bigger plates of material. I will put of all files to Thingiverse today, so they can be easily downloaded. Some photos below from yesterday tests.

T-table for bigger CNC

Hi all,

I had a lot of problem with finding optimal table to my CNC. I try different ways to mount material to it. But all previous ideas were wrong. So I decided to T-table. First try is in plywood, to see how it will work.
So let start.
In my bigger machine I have 435 x 345 mm of work place. Bottom part of it where nut and slides are installed is from Aluminum. On this I put first layer of 10 mm plywood. Bottom groves are 13 mm wide and 7 mm deep, prepared for M8 nut. On the periphery of working place I made 10 mm holes 6 mm deep, where I punch with hammer M6 nuts. This is how it looks:
