Screen designer tips and tutorials / Re: height of title and menu bars?

« on: October 14, 2009, 06:13:30 PM »

Can't give you a definitive answer.

But I make my screens 700 pixels high to fit a 1024 x 768 screen.

You can rely on the "Auto Screen Enlarge" in Mach but I prefer not to use it.

General Mach Discussion / Re: Toolpath view incorrect

Yes this toolpath shown is just as simple as can be to demonstrate the problem.

Where I see it is a toolpath to take a rough piece of stock down to a cylinder.

I am not getting much response, so I suppose there are not many doing this sort of rotary axis stuff.

General Mach Discussion / Toolpath view incorrect

« on: September 25, 2009, 03:34:09 AM »

I think I am right to say this one is a bug.    We will see when someone shows me my error.   

Very simple gcode as follows,

G1 X0 Y0 Z50 A0
A360
Z40
A0
Z30
A360
M30
%

When the "axis of rotation" is selected as X, in toolpath configuration, the toolpath displays correctly. See pic X-rotation

However when Y is selected, then the toolpath view is not displayed  correctly.  See pic Y-rotation

They should both show three simple rotations of the axis.  As the "X-rotation" pic does.

Any ideas of what silly thing I may be missing.

Pushed it up to 5,000,000 and got it down to 24 seconds.

So I also pushed the acceleration up from 1200 to 2000 and now it is down to 20 seconds

I am probably testing the wrong sort of code.  Short segment 3D vee carving. About 1200 lines.

Ordinary Mach, it runs in 13 seconds.

Tempest planner, the best I can get is 27 seconds and that is with jerk set to 1,000,000

Down around 20,000 it is snail pace.

S'pose this is not much interest to you.  What sort of code is best to test?

Look at this link for a few more details,

http://www.cnczone.com/forums/showthread.php?t=36099

The script at the begining of that thread has some short comings.

Look towards the end of the thread for a better version.

Just for your interest Brett these sleeps are no longer needed.

While IsMoving()
Sleep(100)
Wend

They are now hard coded in Mach.

General Mach Discussion / Re: auto zero and touch plate

« on: September 17, 2009, 05:05:58 PM »

wen i hit the auto zero button the z comes down touch the plate goes up ,stop and then goes up to the
top .

I am not really sure what you are seeing.

Code "G90 G31 Z-20 F100" 'probing move, can set the feed rate here as well as how far to move

This line is where the Z will move down till it touches the plate.   It is set at 20mm so it will only go that far then stop.  So you must start less than 20mm from the plate.

Code "G1 Z20 F800" 'put the Z retract height you want here

This line is where the Z will retract to a height of 20mm when it is finished.  An absolute height, not incremental.    Note this presumes your plate is less than 20mm thick.

You can open the VB editor and step through the script one line at a time.  This will show where it is not doing what you are expecting.

OK what "auto tool zero" button are you using?

Where did you get it?  Is it a screenset that you downloaded from somewhere?

If it has an on-screen button that you press to get the action you described then do this,

Go to menu / operator / edit button script, and the button will start to wink.

Click the button and the VB editor will pop up showing the script.

Copy that script and post it here.
