DIY CNC Cutting Tutorial Video #2 - Probotix Fireball V90

This is the first second video in a small series I am making to show how easy CNC cutting is. This video will give you the basic idea and premise behind taking you idea or design and turning into something the machine can understand. I show the entire modelling process in Inventor although most will use other CAD systems it is similar. Then I show the CAM program CamBam taking the dxf export from Inventor and with a few clicks and keystrokes turning it into G-Code.

I have Inventor as my CAD system but unfortunately most people cannot buy this do to its extreme cost $2000 +. I have a student version which was free but unless you are a high school or college student you cannot get a student version. Same goes with Solidworks and most big software packages. There are tons of much cheaper packages out there so google around and find one that you like and has good support. Just make sure that you can export 2D dxf's of faces (ask on forums) or if you can export 3D .stl files for when you get more in depth.

CamBam can be downloaded online for free (older version) or it can be downloaded with a 40 use unrestricted trial for free. Once the trial runs out you have to pay $150 for it. In my opinion that $150 is a fantastic investment as CamBam is an incredibly diverse program at a great price.


Feel free to message me any questions.

Hope you enjoy!

First attempt at HD too....please tell me if the HD video is any good!

Hey I am going to be cutting some birch and I was wondering what feed rates and spindle speed you would suggest. I am going to be using a 1/8 end mill.

[Halo2maniaccc]

For birch I would use about 10 to 40 ipm with a depth of cut around 1/16in at around 25 - 30k rpm. Make a simple part to test cut and try out different feed rates/doc/rpm. There are many ways to approach cutting.....take many shallow fast cuts......take fewer deep slow cuts...or in my opinion the best way take deep (.01 over sized) cuts then come back with a final operation to trim .01 off of the edges to leave a great finish.

Start with shallow cuts and go from there.

Hi, is there a way to generate G-code using open source software that is equally as option full as CamBam? I hear Blender could be a possibility?

[Halo2maniaccc]

CamBam has an older free version although its not open source. I'm sure there is some form of software out there but I doubt it will match the overall versatility and polished look/feel of CamBam. The $150 is a small price to pay to get fantastic results quickly and easily. However if you want that homebrew/diy software aspect then my only suggestion would be to write it yourself. Its tricky but very rewarding once you get it right.

i have an extremly important question for me ... do you have the layout of the pcb of the controller and parts in it ? thanks for the videos

[singhdeolji]

great vedio man really helpful for a beginer like me THX>

[Willcleaver]

@Halo2maniaccc I want to use open source out of principal, to promote the free exchange of information.. I'm not familiar with writing my own software. What program/language do you use to do that? Could you recommend some websites to learn from? Could you do a video tutorial of how you learned to write your own programs and how you write them now? It would be much appreciated:)
