New build Australia, Dremel 4000, smooth build

Mostly Printed CNC - MPCNC Your Builds

Hello.

I had all the electronics hardware from an old 3d printer.

I had a dremel 4000.

I have a cutting size of 450 x 450 to suit a project I built this for.

Very happy with the results.

I work at a cardboard factory and the few jobs I’ve done on chipboard and nylon I think I can get away with a single sheet of cardboard as a waste board using double sided tape to hold everything. I can’t see it moving but have yet to try aluminium.

Gotta say I was pretty excited when I did the crown test.

Nylons interesting as I expected it to melt with the dremel at 25000RPM but no problem.

Using a single flute end mill. Pack of 10 for about $10.

Discovered Fusion 360 at the same time as building this and have to say the process of getting model to gcode is super easy.

Edit: Using this for dremel 4000 mount

Using this for all gt2 2mm pulleys. Download and edit openscad source to suit. 16 teeth.

Cable chain I made for z cables. It works.

Thankyou V1 Engineering.

Hi,

which Dremel mount did you use? Could you please either upload the files or link the source you used to print it? I’ve already printed 2 mounts from Thingiverse, neither of which fit my new model MPCNC :frowning:

Would really appreciate it

cheers

Gary

I’m using this one:

Fits perfect.

I’ve edited original post with this link too.

What kind of cnc settings do you use? I have no experience whatsoever with cnc, lots of engraving and 3D printing experience but the actual cutting is new to me and I don’t even have a starting point. I may try to use f360, does it give you a pretty good starting point?

For taking a model, generating tool paths and converting to gcode that your printer understands , I find fusion 360 great. Not super intuitive

and took some research, I think I had some changes to make to get gcode export tot work. I do t have any notes on this. I’ll look into it. You may be able to make your model in another program and import it into fusion360 for tool path work. As for settings I think I just selected rpm and tool sizes of what I was using and fusion calculates something reasonable. But I really can’t remember. I just know it works when I need to use it.

Thanks for documenting all of this! I have a Dremel 4000, too and soon will start ordering and 3D printing parts for my MPCNC build.
Concerning the end mills, do they fit the Dremel by default or did you get some sort of adapter?

No adapter needed 3.42mm bits or something like that. Note dremmel bits have some flex when doing thicker nylon. Worked good for the chipboard project. I eventually made a mistake and stalled it and damaged my dremmel motor. I had a cheap ozito router in the shed and now use that which I’m very happy with.

Noted! Thanks for pointing that out.
I plan to use the MPCNC mainly for pen plotting and wood milling. I will eventually get a “real” router or spindel.

Since my last post I really dove into fusion 360 and I love it. I haven’t tried exporting tool paths or anything yet but I’ve modeled a ton of stuff and now that I’ve got the basic gist of how to navigate everything I’ll probably give it a shot. Currently my MPCNC is taken apart because I wanted to build a more permanent table for it but I’m almost finished and then I’ll probably look at how toolpaths work in fusion 360
