My new Shapeoko 3 is it just me?

Art,

You are a wizard and one hell of a good man.....

Nicely done Richard.. Congratz...

[Rocket]

Bob,

Thank you...............at 68 years old, I have finally learned the meaning of "learning curve".

Based on my hours (a time and material job on that gear) I would have to price it at about $7200.00.

Any buyers out there........I will negotiate.....

Art,

I have spent many hours trying to fix the problem where
the spindle goes about 2 inches past the center hole in the gear (where drilling takes place)
then instead of staying up, z-axis comes down and cuts (where it should not be cutting)
and wrecks (what would have been a perfect gear) except for that 2 inches where it
went down before it got to center??????

Attached is the .nc that did this.....it was perfect except for that small part...

Help....

HI Richard:

  I see the problem, just not why it occurs..

G20
M5
M6 T3
M3 S1750
G1 X5.274 Y5.512 F100
G1 Z-0.050 F50
G1 X3.930  Y3.910 
G1 X3.928  Y3.910 

change the above to..

  Actually, make is as above, I get the feeling the move to 5,5 came from some other file..

Rocket:

Watch carefully what your editing, and figure out why each time so you get used
to it .. here some explanation of how this one changed..and what each line is doing.

M3 S1750      //turns on your spindle to 1750RPM 
G1 X3.930  Y3.910 F50 //moves to the shaft hole, at whatever height your at, I added feedrate of 50
G1 Z-0.050 F50 //now drop to -.05
G1 X3.930  Y3.910  //now start cutting
G1 X3.928  Y3.910  // etc..

  Get uses to the order of what the lines are doing. Dont copy in the G1 X5... line, it belongs to a gear that
starts at 5,5 in the X/Y.  This one starts at X3.9Y3.9 so youd want to keep the Z up till it gets there, then drop it down
with the G1 Z-0.050 F50, which literally means "Drop Z to -.050 at a feedrate of 50".

Thanks Art,

Do you use G-Wizard G code editor?  If so, do you like it?

Richard

[DanL]

try NC Corrector v4.0 its a free Gcode editor and a back plotter

[ArtF]

Richard:

  To get my Gcode, I use Gearotic itself, or Vectric generally. Or I write it
by hand if its simple. I do recommend any editor you find you like,
as it will help you learn the language. GCode is simple to learn, and those that
know it, know their quality of output is generally much higher for it. It helps
in all kinds of ways. When in Rome, speak Latin...well, ok.. Italian these days


Ciao,
Art

[Rocket]

Thanks....

How did you know I was Italian?

My last name is Rizzolo....

[Rocket]

Art,

Huge question:

Can I make the gear in the attachment, including all those different
sized drilled holes in Gearotic???

RR

[ArtF]

For that youd need CAD. Id use Vectric for example, I load Gearotics gear DXF, then add drill holes.

Eventually, youll probably be able to do that, but till then , youd need a cad/cam program
to add such features.

Art

[Rocket]

I only have a paper copy, no dxf file for this Genesis Clock from Clayton Boyer.

Would Vetrics' Cut to Desktop work, it is much cheaper than the Carve program.

I would have to buy more plans from Boyer in .dxf format.
(or just cut the gear in Gearotic and drill the holes myself)

RR

[ArtF]

Yes, Desktop is fine..very useful if you make Boyer type things... As far as getting the dxf's, if its a gear, you can probably duplicate it in Gearotic, just figure out its approximate DP and adjust till its exactly the right size. To do that, create a round gear with the right number of teeth. Then adjust DP or Module up or down till outside diameter is the same as the drawing... pretty close at that point..
