General Mach Discussion / Re: Self Changing Velocity
« on: April 27, 2017, 08:48:25 AM »
I know it's of no help to you but I have been using Mach2 / 3 for over 10 years now and my Velocity settings have never once changed on their own.

I would suspect human intervention and suggest that you talk with whoever serviced your machines to determine exactly what was done. Having said that, if you copy the Motor settings from the working machines to the non-working machines that should put everything back to as it was.

If, for some reason that does not work then if you post the <your profile> .xml file from the Mach3 folder of a working machine and the <your profile> .xml from the Mach3 folder of a non-working machine (they need to be renamed something like working.xml / nonworking.xml before posting) then we can check your settings and see if the problem can be identified.

Share Your GCode / Re: Demo Gcode
« on: April 27, 2017, 04:42:30 AM »
This Gcode file of the old Constitution class starship was created as a test for Mach4 laser control using the M62/M63 command set. It has been added to the .zip file in Post#1.
 
It comprises less than 500 lines of Gcode so could be modified (copy & paste in Notepad) to using the Mach3 M11/M10 command set.

Mach4 General Discussion / Re: Problem in front or behind the screen?

I found out recently, that running my simple sample with a machine using inch-setup works fine. As soon as I change machine setup to metric units it fails.
Coordinates of failure are different, but not the timecode. Elapsed time is always 5:41.36 - is that the limit for demo mode, or do I have to look for another reason of failure?

Try downloading and installing Mach4 build 3372 from the ftp section. ftp://anonymous:guest@ftp.machsupport.com/Mach4/DevlopmentVersions/Mach4Hobby%20Installer-4.2.0.3372.exe

Mach3 under Vista / Re: Mach3 ignores Z height in Gcode after a while.

Hi Jack,

Welcome to the forum.

If you zip and attach a copy of your Gcode file I will try it here and see if I can identify the problem.

General Mach Discussion / Re: Should I Make These Changes
« on: April 25, 2017, 06:08:37 AM »
The actual layout of the X and Y axes usually depends on where the operator stands in relation to the machine (A Mill, for example, may be configured differently to a Router).

The + direction that the cutter moves in relation to the work should always be as shown in the diagram.

Temporarily disconnect the VFD and test the 0 - 10V analogue output from the G540. If you are unable to obtain +10V then this output from the G540 may be damaged and you should contact Gecko for their advice.

Tweakie.

edit: Because the VFD output from the G540 has isolated ground the 0 - 10 V should be taken (and measured) between terminals 7 and 9

By all means modify things to suit your machine layout and the way in which you wish to work but please remember that most CAD/CAM software (that you will be using) will generate it's layout and Gcode to follow the Right Hand Rule.

This diagram shows the direction the cutter should be moving in relation to the work piece.

Hi Ed,

Mach3 will allow you to G31 (straight probe) the surface of a relief to create a 'point cloud' which you could then convert to a Gcode file for the machining reproduction of the original at any scale size you choose.

Sounds good but be prepared that mechanical probing, like this, takes a considerable amount of time (dependent on the resolution).
