General Mach Discussion / Re: Homing and limit problem

« on: May 07, 2009, 09:56:51 AM »

SOLVED!!

It's amazing what a nights sleep does as I just figured out the problem and of course it's a stupid one!

I had not yet hooked up the A axis homing switch which will be used for squaring, but I had left the A axis limit/ homing enabled in Mach 3 and had also not yet turned of limit/ homing slave with Master under the general settings which you have to do for squaring.  So when I hit "Ref All" it was homing Z, X and Y but then continuing to look for A which never activated and therefore it really never finished homing and therefore the limit switches don't work.

Now the reason I did not spot this is because the A is slaved to Y, there is no DRO movement shown for A while it is homing which if there was I would have spotted it was still moving.  The reason I figured it out today was that I ref/homed each axis at a time and tested that after each axis (XYZ) had homed the limit switches still worked, which they did, then I homed A and of course it never finished homing as the switch is not yet connected (it is on a separate pin to the rest) and after that the limit did not function.

As soon as I disabled the limit/homing of A in Ports & Pins I could then do a "Ref All" and the limit switches afterwards still triggered and limit reached event.

Today's task - wire up the A axis switches


Thanks for all the help efforts and as is the case in most instances it was a stupid (user) error!

General Mach Discussion / Homing and limit problem

« on: May 06, 2009, 10:17:39 PM »

I am setting up the homing and limits on my CNC Router (Joe's 4x4 Hybrid).   I have wired my limits/home switches for XYZ axis to the same port/pin and and my A axis (which is slaved to the Y) switches wire to a different port/pin so I can do squaring.

The limits all work as expected and the homing all works as expected, however after homing ("Ref All") the limit switches are no longer working although I can still move all the axis and run g-code with the exception that the limit switches are inactive (although they are still working according to the diag screen in Mach 3 as I can see the LED go on if I press one).  If I press reset (Mach 3 is not asking me to do this) then the limits are reactivated and function fine unless for some reason I do another "Ref All".

Can anyone tell me what is happening here.

THanks

VB and the development of wizards / Help with macropump code

« on: February 16, 2007, 09:37:35 AM »

Hi all,

I have just built a pendant for my CNC Router I built (see
http://web.mac.com/dacostad) and I have the following in my
macropump.m1s to control the turning on and off of the LED's on my
pendant.

As you can see towards the end of the code I have a single LED on the
pendant that when on means that the pendant is not in MPG mode.
However as there are two non-MPG modes (cont and step) I would like to
have the LED be on for cont mode and flash for step.

At the moment I just turn it on for both (OEM LED 14 and 15) and as I
am not a programmer I am not sure how to get to flash when OEM LED 15
is on.

I imagine that I need something like a do while loop.

Can someone advise me on the correct code.

Here is the code;

If GetOEMLed(59) Then ' X Axis selected
ActivateSignal (OUTPUT4)
Else
DeActivateSignal(OUTPUT4)
End If

If GetOEMLed(60) Then ' Y Axis selected
ActivateSignal (OUTPUT5)
Else
DeActivateSignal(OUTPUT5)
End If

If GetOEMLed(61) Then ' Z Axis selected
ActivateSignal (OUTPUT2)
Else
DeActivateSignal(OUTPUT2)
End If

If GetOEMLed(14) Or GetOEMLed(15) Then
ActivateSignal (OUTPUT3) 'Jog Mode, LED on is cont. mode
Else
DeActivateSignal(OUTPUT3)
End If

Thanks

David

Also the other person has no disabled anything in MSConfig,  but I have also tried disabling everything in the startup tab to no effect.

The other person is not running any network yet, I am running wired.  I did try setting it to 10Mbs from Auto, which is what you see in the picture.

Since then I reformatted the computer and restored back to factory and loaded Mach 3.  The network is currently set back to auto,  but I will set it back to 10Mbs, but I don't think that will resolve the problem as I tested it again with no network connected which is the same as the other person.

General Mach Discussion / HELP Please

« on: January 18, 2007, 02:24:44 AM »

I have just bought a brand new HP Desktop computer to use with Mach 3.  I have only loaded Mach 3 (latest version) onto the PC straight out of the box and run the driver test after re-booting and I am getting a weird result as attached (the first image).

The PC specs are Pentium 4 519(3.06GHz) 512MB DDR2 80GB ATI Radeon Xpress 200 Integrated Windows XP Pro.

The real strange thing is another member of the CNCZone bought exactly the same machine from the same vendor 1 days later and his driver test looks ok (see second image)

Does anyone have any ideas as to what is going on?

Thanks

General Mach Discussion / CNC Router step issues

« on: January 14, 2007, 05:17:54 PM »

Hi all I am trying to troubleshoot missing step and stall issues I have with a CNC Router I built.  For background and troubleshooting to date see my thread at http://www.cnczone.com/forums/showthread.php?t=26792.

Attached is a zip of a quicktime move which shows a 30 sec extract of the driver test.  I don't see any spikes but I do see "noise" which comes and goes on a fairly regular cycle.  Could this be causing me problems?

The PC is a 1.6Ghz P4 running on a mini-atx flex motherboard.

Thanks

David
