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.    ;D

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.  ;D

I have been doing rotary toolpaths in Mach for a while but have never figured out how to get the toolpath display to show them in correct scale.

Played around with all sorts of different numbers in the "Rotation Diameters" on the settings page.  Including negative numbers.

The same toolpaths show nicely to scale in NCplot.  See Pics of NCplot (white wireframe) and Mach3 (blue wireframe).  Exact same gcode.

This example has a diameter of about 80mm and a length (of the cylinder) of 120mm.  In NCplot that is represented about right.  In Mach it never gets close.

Any clues?

Greg

EDIT: The mach pic has the cylinder standing upright and the NCplot has it lying on it's side.

Tangent Corner / Anyone near USshoptools? Anaheim, CA or Warren, MI

Anyone near USshoptools? Anaheim, CA or Warren, MI

I want a couple of ER11 collets and they want more than they are worth for postage to Australia.

They would only weigh a few ounces.  These things are tiny.   Postage to Aus should surely only be a few dollars.

I could stick some money in your PayPal account.

We can't get imperial size collets here.

NC Pod / Some movement on the NCpod site
« on: April 15, 2009, 11:03:35 PM »
After nearly a year there has been an update posted on the NCpod web site.

Happened a month ago and I only just noticed.

VB and the development of wizards / Input Box Function
« on: March 29, 2009, 12:58:33 AM »
I found this on the Cypress Enable Language document.

Sub Main ()
  Title$ = "Box to ask for a number"
  Prompt$ = "Enter the number"
  Default$ = ""
  X% = 200
  Y% = 200
  N$ = InputBox$(Prompt$, Title$, Default$, X%, Y%)
End Sub 

When this Input Box is run where is the answer?

How do I retrieve it?   Where is it stored?  In a parameter?  I am looking for an integer.

I hope that makes sense.  I don't even know enough to ask the right question.   ;)

I am probably a bit odd and different.   ;D

I often want to drill a series of holes and use the CNC side of things to accurately  position each hole but I then use the quill to manually drill the hole.

I just find this way of doing it is often quicker and easier than getting the drill feedrate just right, the depth of dril, etc in the code for just a simple one off job.

So my suggestion is where the selection is made, in the wizards, for G81, G83 and G73 maybe we could add to the list, the selection of an optional stop.

Probably makes no sense to most of you but for me it would be a boon.

General Mach Discussion / Spindle speed syntax error
« on: March 27, 2009, 04:51:52 AM »
For a little while I have been getting strange behaviour of my spindle speed control.

Thought it must be a glitch in my electronics.

The symptom I have had is, the gcode sets the rpm.  The DRO updates as it should..

But the actual RPM is whatever was last used.  Until I nudge the override, then it goes to the correct rpm.

However I have discovered there is some problem with the spindlespeed.m1s

Here is the line.  As far as I know this is Mach standard issue,

rpm = GetRPM() SetSpinSpeed( rpm )

The VB editor does not like it.  Calls a syntax error on "SetSpinSpeed"

Version R3.042.022

General Mach Discussion / Pause/Feedhold LED broken again?
« on: March 09, 2009, 04:43:56 AM »
In November (3.042.018) we got the pause/feedhold LED fixed after such a long
time.

In January (3.042.021) it appears it might be broken again.

Mach Screens / Button to call a menu item ?
« on: February 19, 2009, 04:05:58 PM »
I know I have seen info on this somewhere but despite my search efforts I can't find it.  :)

Just want an on-screen button to call the video window plugin, menu item.

Sure I can do this with a button script.     This is with Scream4.

Thanks,  Greg

General Mach Discussion / Looking for an alternate (small) video window
« on: February 16, 2009, 04:39:05 PM »
Going back a year or more Mach had a smaller simpler video window.

I have asked if this was still available but sadly it is not.

I find the newer video window takes up more screen space and has lots of features which I do not need.

On a small screen, when using wizards etc with the video, smaller would be much easier.

There are third party video windows with more features but I am after one with less.  Or at least can be resized.

All I really want is a small video window with cross hairs.  Nothing more. :)

Anybody know of one or have any bright ideas of what I could adapt ?

Greg
