Surface Table

[Kasey Jones]

Does anyone have code to allow me to surface my table going back and forth (down the x axis) vice the pocket way (cutting in a rectangle).

Thanks - Kasey

Kasey,

Check this thread.

Here's the version I currently use for my own spoilboard:

' File for surface planing the 96" x 48" spoilboard
' ' Copyright 2006 David Buchsbaum. Unauthorized use or sale prohibited.

&length=96.5
&width=49
INPUT "DEPTH" &depth
&step=1.125

BEGIN:
JH
SO,1,1
&yvalue=0
JZ,.02
M3,5,0,-&depth
MX,0
LOOP:
MX,&length
&yvalue=&yvalue+&step
MY,&yvalue
MX,0
&yvalue=&yvalue+&step
IF &yvalue>&width THEN GOTO FINISHED
MY,&yvalue
GOTO LOOP
FINISHED:
SO,1,0
JZ,1
&depth=0
INPUT "ANOTHER PASS? ENTER NEW DEPTH OR [0] TO END
IF &depth=0 THEN END
GOTO BEGIN

Did I miss something or should the third line from the bottom be;

INPUT "ANOTHER PASS? ENTER NEW DEPTH OR [0] TO END" &depth

Hey Ed,

I'll make a programmer out of you yet!

Here's the "package" I use.


surfacing_along_XorYaxis
surfacing_along_wood_grain_X.zip (2.6 k)

It's derived from David Buchsbaum; I and Mike Richard hacked his project.


Play with it but I know there's room for improvements, code tidy and I think there's a bug with SB3 about the file call up where SB3 use it's last remembered used folder to look for the sub file... gotta check at this. I change the version I use on my control PC with a full folder path to the subs.

I've add this idea to my blog 'to do' post so I'll post my tweaks and improvements when I get a chance (maybe this week end). I want to track down the FP subs call up issue, get rid of the 'Ready to Rock & Roll' annoying prompt (sorry David; see you changed that too), add a re-use of previously used settings, implement an half pass (half depth for final work; more detail later) and some more minors... stay tunned.

OH, and I promise I'll keep credit to the original idea author and contributor too!

[David Buchsbaum]

Whoops, Ed, glad you were paying attention.

I've also modified the above file with a version for surfacing boards of any size, like Paco's, with the added feature of specifying a lead-in and lead-out distance where the machine only climb cuts to eliminate tear-out along the edges of the board, but reverts to back-and-forth cutting between the edges for speed.

Here is what prompted me to write that variation...

[Bill Young]

Hey Paco,

How about sending me details on the file path problem you're having...I haven't been able to duplicate it.

Paco / David -

The file worked like a charm! I didn't get any file path problems either.

Thanks
Kasey

[Pascal Riendeau (Paco)]

Great!

Bill has identify the bug; it's related to relative path used with custom cuts and the 'Set part file folder'. Other than that it work correctly.

I have rewrote the code (tidy), make it a single file, fixed some minors glitches and added some new features. I'll test the code on cut mode today and I should post about it today on my blog.
Here's a teaser:
quote:02/2007 - Major clean up and tidy of the code. Implementation of a few ideas: simplifications, half pass (half stepdown), overshoot the ends (to avoid tool marking), re-use of previous settings, display (print on the Part file message screen) of the depth of cut progression.

[Pascal Riendeau (Paco)]

David Buchsbaum when he first post is code...
quote:Feel free to use this file if you find it useful, in exchange I ask that you post any improvements here for use by all.

Here's my latest release.

You can see more details about it on my blog's post about it; the README and a diagram of how the code is working. Check it out! Let me know what you think.
