The machine in this video is pretty much running through basic tests of my micromill code, using the lm628 based controllers from techno-isel running on linux. After 2 more segments of code are implemented, it'll be adapted also to produce orthoses, and ultimately, will have a 4th axis added to it to manufacture orthotics automaticly with 0 human intervention after inserting and clamping down material. I'll also be using it to make the jig and base plate assemblies, reducing expenses for jig manufacture by no less than $1000.00 per jig, so yes, it's been a really good day. :drinks

What are you showing here that is different from using existing CAM software?
Is you system significantly cheaper or better than traditional M and G code systems?
Cheers

In addition to any other machine that uses the Acroloop series of controller, is now also compatable with techno-isel's hardware, which means my native milling software will be able to work with considerably more machines, instead of converting the milling data to g-codes. Milling an orthotic with sofware designed specificly to make orthotics is also generally more friendly for setup and resuming of orders. My next targetted controller will be the galil controller, of which, I currently have their 10-base T controller in house for that task. The 'boring operation would be a good indicator that communication layer is ready for use, as the updates are every 0.010" (1/4mm) and the machine is running smoothly even at that tight of a point to point resolution. On a more positive note, having the machine in house gives me the ability to do one of the things my customers have requested, to add order information to the orthotics themselves, rather than to inscribe or label them. Of key importance in this area is the proximity sensor, which is calibrated to determine the length of each tool to be used, +-0.001", which combined with the topographical data of the orthotic can be used to scribe the order number right into the parts without weakening the structure of the device. -
Just another video of some of the features I build into my software, which will enable me to allow my customers, at minimum, to produce some of the components for my scanners. and to quickly setup a new jig without having to guess.at alignment.

Let me be the first to warn you that you may be visited by a friendly podiatric cyborg from the future hell-bent on wiping out you and your creation in the knowledge that this is what started the RISE OF THE MACHINES!
You don't have a ped-egg do you?

Again my question is why? (Genuine question as I am very interested in improving things and not maintaining the status quo)
Processing systems like Heidenhein are excellent at 3d work and have excellent 'look ahead' properties to keep things smooth and effective. They can also 'flip' jobs over to minimise user input etc.
The interpretation of modeling out put to CAM to M code is all automated and pretty simple (once set up).
What is different in your approach?
To make me move to another system there would have to a financial benefit - time savings etc.

Here's the abstract
I was just showing some of what I've been up to. As of now, I have 2 systems to install out of the country, and 1 or possibly 2 systems in the country to install.Last edited: Mar 9, 2009 -

Just an FYI for those of you running labs with Techno-ISEL orTechno-CNC routers. It would be wise to inspect the thrust bearings for each axis and verify at minimum that they are angular contact bearings and not cheap bicycle bearings. My own router, as shown by the previous videos started developing backlash and after discovering the kind of bearing that it used , I ordered replacements from Vxb.
The original part,6200rs should be replaced with 7200B, for example, and will result in tighter tolerances.
What gets me about the Techno line of CNC routers is how they can put $2.00 bearings into a $20K machine. I wouldn't be able to look at myself in the mirror if I did that. For $6.00 more per axis, the bearings will both last longer and provide greater accuracy, and it seems a shame to not spend the extra $6.00 per axis.Last edited: Mar 17, 2009 -
There is a new video on my playlist that shows my patented method of producing foot orthoses. It has the advantage of continuous feed machining, instead of accelleration to a constant speed, decelleration, stopping to change lanes, etc. In addition to actually making orthoses, I am also designing my software to allow a regular end user of the product to make repair components for itself, effectively making it a self-repairing unit, for much of itself. I still have to align my machine, but afterwards, will make available photos of surface quality. This current experiment involves reducing the ball nose endmill size to 1/4", and seems to have been successful. This means an improvement in shape for all devices, and in particular allows for a much steeper climb into devices that need it, such as the UCBL design of orthotic. The caviet to this experiment is that the spacing between machining passes needs to be reduced for a smoother finish, but it does in fact have the advantage of saving 10% on material costs, allowing for 9 to 10 feet on a 12x24" sheet of plastic, instead o 8 to 9, using a 1/2" endmill or larger.
Note: In this example, I'm using a 2 1/4 HP router motor, which is obviously overloaded and currently running at 250 IPM (Inches per minute). In the video, you will also note that the spindle slows down in steeper cuts, so the next experiment will be at 200 IPM.Last edited: Apr 21, 2009 -
