Hi to all,

as a first post on this forum, let's start with introducing our machines to eachother. I'm very curious to see the machines other people made, and control with cnc-usb. So please post 1 or 2 pictures and tell about it. How did you make it, what are the dimensions, etc.

I will edit this post tomorrow and add some pictures and tell something about my machine.
EDIT: a bit (2 months) later, but my machine is here aswell... scroll down.

I am 95% finished and the machine is operative (build started last August):

- Moving gantry router with a range of 36" x 32" x 8"
- Structure built from highly rigid bamboo plywood
- Linear ball bearings 20mm from Glacern.com
- NEMA34 steppers with 15mm precision Kuroda ballscrews, Gecko 203V drives
- Table is 80/20 brand aluminum extrusion on a bamboo plywood box, mounted on a cart
- Chinese high frequency spindle (first 1.5kW, now 2.2kW with Hitachi VFD)
- No cost figure, I stopped counting at some point......



Ha! I notice you can not post picture here. Oh well here are the links to some pictures:

For now I have only these two pictures. Taken with cell phone. But I will make more pictures of the controller box , touchscreen computer and machine. This time I will use regular camera :mrgreen:
I convert the machine from manual to CNC. Original machine is LittleMachineShop Hi-Torque Mini Mill. I bought the CNC convert kit from CNCFusion and controller board, step motor controller and step motors from Probotix.

Hi

Just great that there is a fora to get help :D

I'm new to CNC, but you have to start somewhere, found an old machine that have been used for education in a school, the guy I bought it from was going dead in the electronic...

I'm now going to start of with Andrej's controller and some other stuff from him - seems that the software is more strait forward.

Picture of my machine:

Picture of the old controller:

styring_1.jpg (53.11 KiB) Viewed 10298 times


Future plans::
Webcam, 7"/10" touchscreen, external keyboard panel..for quick functions..
Just can't wait to get this up and running.
Do a lot of simracing and build some add-ons for wheel, so is hoping to make some fancy stuff in the future.

What thickness of aluminum you can mill? I thought about getting one of these but everybody told me that on milling aluminum this machine will not perform too good because the motor is to weak

Hi,


I Use For milling aluminium sheet 1mm- 1.5mm- 2mm & 5mm
end mill 1-flute or end mill 2-flute, it's good result with advance 500/min ~ 10 000 trs/minutes spindle
and multi pass depht ( 0.3) & milling in "Avalant" Mode ( sorry in french!)

I don't use the original spindle ( type E240) use for this : Brushless Spindle HomeMade by Me ;)

I post new pictures asap because now i modify the table machine for big good result !




Regards

@JerryBurks I really like the pattern you milled on that piece of wood :)!! Would you be able to share the G-Code file? I'd like to try and make a smaller version :D

Yes I can but at 3MB it is too long to post it here. Instead you can try to download it from my Public Dropbox.
I will leave it there for a few weeks and then delete it.

Obviously you would have to scale it somehow to your blank. I used a 90-degree V-bit at 15000 rpm to cut in an old maple shelf board. To get a clean cut of the intricate tiny squares you need to experiment with you starting depth. Too little and you don't see the detail, too much and it just makes a fat groove. And you REALLY need a sharp bit.

Executing the code, an earlier version of the planet-CNC software got stuck due to USB buffer overrun (if i remember correctly) but I could resume with no problem. But that was in the old times, some 200 versions ago :mrgreen:

Admin: I zipped and attached this g-code

Oke, it's been a little longer than 2 days to post pics of my machine, in fact it's more like 2 months, but here goes:

My machine has a working enveloppe of 1020x520x150mm. The base of the machine is made from 60x60x5mm steel square tube. It uses 16mm supported linear roundbars, and 16x5 ballscrews. Nema 34 steppermotors with 3Nm torque, 48volt power supply and the MK2/9 controller.
Still not finished, I'm still working on end / homing switches and need to mount the cable chain. And I still want a toolsensor, 4th axis, aluminum T-slot table instead of the poor MDF. And I want to make a box underneath the bed with mounts on it to place screens in, so that I can mill aluminum with a flood cooling.

Here are some pics.

3.jpg
One part of the baseframe, 1200x240x60, welded with oversize, cnc milled to be square, flat, and the right size. One side isn't milled all the way, but left 10mm to have a small edge to support the linear guides. Makes it easier to mount them parrallel with the frame.

Both base parts connected to big angle irons. My machine is at the attic, and it had to be made into pieces to get it up there. It's very heavy...

Here is the base of the machine complete. The frames on the sides are welded, and bolted underneath the angle iron. The long tubes in between are bolted.

I couldn't find a cabinet for the electronics, that suited my needs. So I designed one myself. I asked a company to lasercut and bend it, and TIG welded it myself.

Here is the cabinet completed and mounted to the machine. The panel is changed now, and will change again soon to get a start, stop, pause and maybe more buttons (keyboard shortcuts).

8.jpg
All the parts for the electronics. Look at the wooden bridge. While designing on the computer should be sufficient, it's always good to try things out for real first. You'll see lots of things you hadn't thought about before on drawing.

maximum of 8 attachements reached, here is the rest of the pictures.

9.jpg
The electronics cabinet. The area above the MK2 board on the left, empty here, now got a earth rail. All cables with shielding goes over that rail, above the rail the isolation is removed around 15mm, and the cables are strapped to the rail. All shieldings are together at one point, minimizing EMC. The PVC on the right is my watertank for the spindle cooling, there is a small 12v pump inside. The psu above is 48volts for the steppers.

Here is the watercooled spindle. It's 1.5Kw and got a ER11 collet. Maximum size collet normally is 7mm, but there are oversizes for 7.5 and 8mm.

Hello

I would also like to introduce my machine times.
It was built this aluminum, three parts, I had my mill from a friend.
The machine is still under construction, but can already be moved over the MK1.

My DIY CNC Router
5th generation CNC build.
I finally got it right.
Double 3/4" Plywood frame.
Igus Double rail with dryline bearings.
Roton Hi-Lead - Lead screw.
Probotix yellow motor kit
Will run over 200 IPM
Didn't have a need to test it any further, I'm cutting wood.
Will cut at 50 to 60 IPM all day. Yes I run it all day.
Had it in a small room but tore it down and building another, lighter and quieter.

Some pictures of the beast :twisted: I originally had a Shapoko2 which was fun but wasn't up to cutting aluminium so after many upgrades and still couldn't do what I wanted it just wasn't rigid enough I decided heavy steel construction was the only way to go now weighs in at 140kg :shock: anyway with some help from Zap Automation where I bought all the parts this is how it turned out.

I'll enter this.
I've built 8 machines using CNCUSB Controllers. Recently migrated to the MK3 from the MK1.
To be honest The software and hardware is amazing. The MK1 is still good.
This set-up is my latest build. I used materials from several places. The rails from a site that sells V Groove Rails. Aluminum plate from a local supplier.
This time I'm using belt drive I picked up on Amazon.
Machine cuts 23X32 and is perfect for doing a lot of projects.
In setting up this new build I ramped it up to 500 in a min but couldn't get that fast due to the size of the machine. I ran a simulated project with a lot of changing directions at over 200 in a min and it was solid.
I would never be able to cut at 200 in, I'd snap bits. Many times I use routerbits as small as .015.
