made a *caugh... caugh* small error

Can happen to every one!

Yehaaw, made it, in front of my students...

I do not think it's a problem, misses in CNC programs and manual manufacturing happens all the time, just wait. it's this that makes a good CNC programmer/manufacturer, try hard to do, try and .... fail... the first time, but then, finally, on the mark on every take....it makes a good and thoughtful programmer, as a mcahine'/workshop owner you need to let this s..t happen, it makes you worker better to earn your profit...
I know, 30+ years in single part machining, I done this, not every day but close.
Nothing can protect you of this (If you not have exeptional clever or lying or lazy personal)

Don't kill your machines to much and do not abuse to much cutting tools, you'll be fine :)
It is part of the development of a future expert

BTW, be carefull!! (closed doors, all security locks on its place)

cheap action cam, worth it?

Bought a cheap 1080p action cam

Are those any god? the Gopro5 I was using was "murderd" by some one, the case is broke, can't be fixed according to Gopro, they don't repair their cams. You need to buy a new one.
The Gopro has done a good job with good results.

Did'nt use action cams much so $400 for a new one, not a chance..
Bought a $30 cam instead.
Did edit it in 720, din't made anything much different
Check the video from the $30 cam


I don't have a good Gopro video from the 5 version to show, but we did a video with the gopro4.
Watch it and see if there are any differents..


I know that the cheap cam has no good close up/macro function and I did go close when filming
But for $30?
farly good I think
The actioncam got wifi and a pretty good app.
What cam then? it's a Rollei actioncam 372.
I'll try it more and present the results later

It's later: the water resistance plastic case has no chemical resistance what so ever, using it with cooling fluids make the plastic to crack and it falls apart, useless

Milling in lathe, siemens sinumerik 840D

If you got driven tools in your lathe, try this
Mill in the lathe, on the edge of the workpiece.

milling in lathe
If you can't see the moving gif, check my youtube

Raw code with comments:

N10 G54
N20 WORKPIECE(,,,"CYLINDER",0,0,-100,-80,200)
N30 G0 G53 X400 Z600 D0 (safe position, tool change)
N40 T="FRÄS10"
N50 M6
N60 G94 F100
N70 SPOS[1]=0 (set chuck (workpiece) to 0 degrees, need to be before SETMS(1) )
N80 SETMS(1) (set work spindle, driven tool)
N90 S1000 M3
N100 TRANSMIT (start G17, end plane milling)
N110 G0 X70 Y35 Z3
N120 Z-3
N130 G1 Y-35
N140 G1 X-70 (value X2 without DIAMOF, program in dia)
N150 G1 Y35
N160 G1 X70
N170 G0 Z5
N180 G0 G53 X400 Z600 D0
N 85 TRAFOOF (return to turning, G18)
N190 M30


How do you do that?
The programming make you able to do a mill program on the edge, see the pictures below.
If you does'nt use DIAMOF (and don't) the X-coordinate will be programmed in the double value, the machine (lathe) use diameter measurment on X.. If you use DIAMOF do'nt forget to DIAMON after the milling, otherwise everything will be interesting when you try to do your ordinary turning afterwards
And don't forget to shut off the milling with TRAFOOF (yep, correct spelling)

Programming, the blue square is the milling in the example, Zero on X and Y is in the middle, Z- is down into the picture

Make a comment if you want a more detailed explanation! :)

New android app

Made it again

I made an new app for android without certain public interest.
I thought, " I want to make a new app, no idea what type, but I want to make one"
And then it hits me like a flash
I shall make an app that shows this blog in a little window on an android thingy

This app is not truly useless, you can use this blog much easier with the app, just open the app and read this fabulous blog.

You can thank me at any time :)

So where do i find this app?
Go to Google play <-link

The apps name is CNC Coding Guide Blog and is a free blog reader app with this blog in aim.
However, I'v got a small problem with it.
I can't test it before publishing, lost my android phone, or my daughter did, it is somewhere in the house, so it is up to you to try it out and tell me if it's a hit or a miss.

Have a nice one

3D printing

Instructions for the Grabcad Print software we are using on our Stratasys uPrint SE Plus.

The model we are using is a .stl-file, other file format will work, but for the most, .stl is the most used for 3D-printing

After you started the software, you need to add your model to the print software.
Just click Add Model and choose.

Add to grabcad















The Grabccad software will now place the model quite random, in this case, the model are made to have the right side down, not all model do this

Place the 3d model










If the model do place itself wrong, use the orient tool to put it as its best on the tray.
You can choose different angles that fitts your model
One option is to "orient face to plate", choose and click the face that will be at the bottom

align the 3d model










In case you want to print out more then one model, right click on the model and choose duplicate, add a value.


duplicate models












If the number of model makes the total larger then the tray, Grabcad makes a new tray/plate automatic


multi tray









Befor start the printing, check the estimate (down in the middle)
That will show you the print time and amount of material used

printing time est











Timelaps of the printing

















Printer specific settings and setup, too much to add now, but who knows :)
