    Aha. OK.
    What I would do is
    attach the aluminium blank very tightly to a flat wood base,
    then mill out the middle,
    then tilt the wood base up a bit (to 15 degrees) and clamp it.
    Then mill off the corner with the side of the cutter.
    Then reverse the whole thing and mill off the other corner.
    You could even calculate the thickness of the wedge you need.

    Start with softwood - it is usually cheaper. And it 'bends' more easily too.

    Cheers

    Hi Roger & Khouj,

    I currently use ArtCam for my CNC designing. Originally produced by DelCam, it was bought by Autodesk who have now decided to dump it. Their solution is to offer their more expensive product - Fusion360.

    As you know, my design needs are simple. Mainly 2D shapes and I am just venturing into 3D. I need to find an easy to use Cad/Cam programme. Something nice and simple, no mention of confusing things like 'wireframes', etc. Something that will not take a University degree course to learn. I haven't the mental energy for that. Have you any suggestions, for software that is similar in ease of use to ArtCam?

    Cheers

    Gary

    A bit difficult there. I have used several (expensive) 3D modelling programs and found them all painfully slow to use and gave up on them. I have decades of computer programming experience, so I do my design work in my head, transfer it to AutoSketch for 2D realisation and documentation, and then I program it myself by hand. So no suggestions at all. Sorry.

    Cheers
    Roger

    Well I guess you can do it my way sir the base software I used is only sketchup 8 the free version, I made my own plug-in on sketchup to be able go to the next step (CAM Programming) I also develop my own custom CAM software that has no expiry, no nonsense, no subscription or whatever hehe, just copy / paste the file and voila! a perfect CAM program that can do simple to complex CAM programming, also the plug-in in sketchup is also copy/paste, because I made it in .RB file which can be directly put in the plug-ins folder in sketchup program files, I can give you all the programs and plug-ins I used and develop if you want im free on saturdays and sundays, the total files are only 18 MB, and can be used in windows XP,7,8,10 32/64 bit, about the fruit of labor, I guess it depends on you on how generous you are sir , you can contact me @ facebook Jay Nayon the bald but cute guy with a fake sun glasses hehe

    That is very generous of you.
    You could upload it just once to a Google folder if you want - not sure of the details.

    cheers

    Hi Khouj,

    You are very inventive! Why not sell this setup on eBay? I think there are many newbies like me out there willing to pay for such helpful software. Could you put up a couple of screenshots?

    Cheers

    Gary

    Hi Roger & Khouj,

    I need help with Mach3's jog speed so I can try some manual milling. In my motor tuning, my 'X' and 'Y' velocities are set to 42mm/sec. I can see the JOG button on the Program Run page, but where do you set the %jog speeds? I want to be able to get 5mm/sec, 10mm/sec and 20mm/sec.

    Cheers

    Gary

    The tab key opens the jog page. The Mach3 manual explains it all.

    cheers

    Hi Roger,

    Got it. I googled some mach3/jog tutorials and they mentioned 'tabs' so I looked at the tabs at the top of the mach3 screen! I didn't realise they meant the tab KEY.

    Cheers

    Gary

    ------------------------------------------

    Just tried 'jogging'. That is really useful. I'm going to try some simple, manual, milling now.

    For some reason I did not get your message sir. you can add me if you want.

    You can add a gamepad to make your manual milling convenient, you can slow down or fast forward "on-the-fly" it makes the job so much enjoyable and dangerous too if you`re toying with it specially on hard metals.

    Milling Aluminium - too fast?-20170328_155816-jpg

    Again you need a software for it to configure the buttons and cursors to function according to your preference.

    One big drawback on my CAM technique is I need to teach you on how to do it because my style of CAM process is in the 3D itself, you also need at least a 1080p monitor (22-24 inch) to be able to process the CAM specially on metals that involves 0.2mm gap between them, but the end result on this technique is you`ll be able to dictate the spindle on where to start first and so on and so forth, this is the reason why I dont really need a tool changer to do most of my work, to cut the story short, whatever you do on the 3D environment the spindle will just follow what is written on sketchup, the good thing about it is you can do a floating route path, meaning even if there`s no 3D model on it, say like for example you need to hatch or bore a hole on some specific locations on your product then loop it to be able to reload another object then start again vise versa hehe.

    Milling Aluminium - too fast?-20170313_075102-jpg

    This is the reason I put jigs on some of our machines to be able to reload swiftly on the materials, I can park the spindle anywhere I want on the table (safe side) and loop the program to do hundreds or thousands on it. to cut the story short I am the one dictating the spindle what to do, not the CAM software which has a limited capabilities on what I want. It cuts direct to the point without excess unnecessary movements, and park to a specific point where I want them. so the scenario will be like reload materials then push the start button on the gamepad then after it`s done, take out the finish product then reload another blank material then start again. it`s a kind of boring job is`nt it?
