the file with the R1.5 give little scollups around the edge of the sunnies, I noticed that the stop start motion was worse in one direction than the other,

I looked closer, to see that if I applied pressure to the gantry the stop/start action was remarkably reduced, further investigation showed the stepper was loose the vibration of cutting with the 55mm Cutter and the larger router must be loosening the bolts (the stepper is mounted upside down and is suspended by 4 hex bolts I have since added LOCTITE and will hope this problem is fully resolved,

feed and speed are set to 400mm/Sec with 6000RPM on a 2.5mm Standard two flute end mill.

I will post a video tonight for all to see...

thanks for your help...

Ps how do you tell if the speed it to fast or that the cutter is the wrong style

not sure what I can do with this btu surely it would make a great sim

it has motion in three directions up/down at the back, up/down at the front, and left to right roll...

graham,

    Thanks for the NEW improved File, (it washes clothes well !) Seriously I have just downloaded it so haven't had a chance to try it out...

One thing I did notice was that every second line had Xnn, Ynn, R1.5 and then the next line had the Xnn Ynn Znn. will this not create a slight scollop shape  befor the drop in Z-height?  (I also added the G94 [feed per mm] as I have no feed back to the spindle for a G95 [feed per RREV] )


    What was the reasoning for adding the R1.5..?

Over the week end I was having a think (couldn't do much else as I fell through the Ceiling onto the CNC table and have hurt my back aslo brused my pride rather surverly) if I can set the Zheight then carry out a Xnn Ynn Inn Jnn G-code would this give me a smoother cutting file, I realise that the Zhieght would remain constant but because of the shape I would either be cutting less or more material depending on where about on the shape I was cutting??

sorry Graham, I sent you the file that has 4 half height tabs -these tabs were going to be used to ensure that the sunnies stay attached to the rest of the material but as it turned out with a vacuum of 20"Hg and blue tack sealing it there is no longer a need to use tabs

I got the 1M43S from the clock that runs in Mach3 when you hit the START button, so it mighit include the movement from X0,Y0, Z30 to the first point of the lead-in the moved to Z-4 the 6mm arc for the lead-in the cutting of hte job the 3mm overlap, the 6mm arc for the overlap, the move from Z-4 to Z30, the return  and the rewind of the program..

Don't get me wrong I like the way you worked out hte 200mm/Min feed rate this might be a very usefull thing to remember for the futer especially when making small moves as apossed to long flowing arcs etc...

Ok back again!!

   the MC9 file is done using layers   [auto save]
 so if using MC you will be able to view all the different layers etc...   [auto save again]

!!!***  guys as this is a customers file [read friend of the family] ...can you do the right thing and ask B4 using it yourself***!!!!!


Oh lucky this time I had it saved ( I have no idea what the hell is going on here !!)

sorry back on track

the file is faily basic there is a surface that has a curve in both the X-Z plane and the Y-Z plane.  the X-Z is on a radius of about 132mm and the Y-Z is around the 32mm Radius

at Z=0 there is a 2D chain of a pair of sunglasses, (well quite a few if you consider the 5 different layers )

the 2D chain is then projected to the surface this creates and a splined curve, this CORD is not projected perpendicullar to Z=0 as this would mean the    [auto Save] 
machined sunnies would infact be longer than the 2D chained image. but instead it ahs been wrapped (if this make sence)

anyway here is the Zipped Mc9 file. if anyone has any Q's pls just ask

I don't know what hte hell is going on here every so oftern my broser updates the page and I loos all the stuff I have just typed, I really thought I was over my Dummy spit, but I am starting to see red again

-This reminds me of the video clip of the bloke who looses it and bashes his monitor with the keyboard and then starts laying into the computer, I thought it was funny at the time but am beginning to wonder where I can get another keyboard to bash the living daylights out of this Lappy

So I'll post know B4 loosing it again and continue in a Moment
