Well, I don't know what I would do without this forum
I appreciate any one who can help to keep me moving forward
My new problem is I lost my "all reference home"
I do have the yellow abnormal light on
I read everything I could find on the yellow flashing abnormal light
and I realize it is an alert to a irregular condition....
But, I do have yellow lights on m1 limit and m1 home on the
diagnostics screen....
I can't get those to go out....
when I try to "all reference home" the z axis reverses off the home switch and
the "reference home" cycle stops right there with a message "triggered limit switch"
I suspect this problem is link to my yellow lights on M1 limit and m1 home
thanks in advance for taking the time to help

Sounds like you may have noise or dodgy switches. If the Z references fine (machine coords go zero for it) then it is likely your X that is the problem. You could try setting a ddebounce interval of 2000 in General Config to see if it makes a difference.

well, I found the configuration for de-bounce interval.... it was set on 100
I set it to 2000 but, it do anything different
after hitting reference home the z axis zero's out reverses off the switch and stops
with triggered limit switch....
It started doing this after I created a sample project on Cut 2D....By accident I checked
"scale data with job" when I ran the program x and y both went in the opposite directions
of the home switch when it became apparent they had no intention of stopping
I hit the E stop just about the time it crashed....I don't think it hit and if it did
it didn't hard....
before I proceed don't I need to see if I can't figure this out ??
-
Try to reverse signal from the switch config menu.
Try active low or high for the X and Y axis.
Just a guess.

okay this is what I got
on x- and x home... active off moves away from home swtich
x- and x home both off... moves away from home switch
x- off and x home on...moves opposite direction
both checked on nothing....
I never did get it to move toward the home switch
does this tell us anything??
-
Can you attach your xml please and I will see if there is an issue in your config.
Hood
-
I know you have explained this a thousand times on this forum
but, could you explain where to find and how to
get an xml and I will send it
thanks!!!!!!!!!
-
Open Mach and look lower right at the profile name. Close Mach and browse to the main Mach3 folder and look for a file with the profiles name and a xml file extension. Copy it to your desktop and rename to something like trparker.xml then use the additional options button on the reply page to attach to the forum.
Hood
-
I sure appreciate you looking at this
this machine is like 2 weeks old
I hope I had messed the thing up
-
you know out of curiosity I opened this file
and it is empty ....
the profile name is S720 and I did exactly
as you said...I will go and look for another
-
Ok xml looks reasonable, spindle is a bit whacky but thats nothing to do with the homing so wont bother about that at the moment.
First thing to do is make sure the machine if off any limit switches then look on the diagnostics page and see if any of the Home or Limit LEDs are lit (m1+ etc)
Hood
-
Okay I figured it out Imac can't opened this file
internet explorer has to open it.....
so its not empty
-
m1 limit and m1 home are both yellow
-
Ok , press your X switch now and see if they go out.
Hood
-
Sorry to be so ignorant
but, you do mean to press on the switch on the diagnostic page
it will not go out....
I can go to the Z position until the yellow light comes on back and it goes out...M2
I can do the same for the x axis and the light goes out...m3
but the y axis when I jog to the home switch on y it is already lit and it will not go out
when I back off nor when I click on the on screen button
-
I was meaning physically press the switch by hand while watching the diagnostic page.
Sounds like the switches are faulty on the Y, Also sounds like you have the active state of the X set wrong. However that doesnt really make sense as I would have thought all switches would have been Normally closed switches but it seems by your description above the X is normally open and Z normally closed.
So really what you want to try is like I say just press the switches with your hand and then tell me what happens on the diagnoostics page for X Y and Z when you press their respective switches (m1 is X, M2 is Y and M3 is Z)
Hood
-
Well, you know I don't think these are the kind of switches I have
they are a two part switch they are magnetic or something like that
I have S1000 Zero 3 machine from Germany I think they used magnetic switches
which up until yesterday it was homing great....
after I ran that G code from Cut 2D its started this
-
Ah ok its prox switches by the sounds of it. It may be magnets or may just be a ferrous metal that sets them off. If you have a bit of steel you could try passing that close to the prox switch, something like a screwdriver blade.
Hood
-
okay they are magnets looking closer to one it has written Meder Magnet
I use the tip of a screw driver passing over each switch in all possible ways
while watching the diagnostic page I saw no change
-
You would need to pass a magnet over them.
Ok from what you said before it seems Z is ok, X has active state the wrong way and Y is just not working.
What to try is disable the Y home switch in Ports and Pins and change the sate of the X limit and home then try and home the machine.
Hood
-
this is what I found out
working in the port and pins....input
with X- active high
the x axis works good but not y
with y home off de active x axis will not worl
with y- off de active x axis works but not y
when i deactive any combination of
with y- deactive
with y home de acitve x will not work
with y- deactive
with y home deactive y will not work either
with x- active high
everything works except y
I did have z and x working but y moving run direction
but, I could not duplicate this again
I hope this makes sense I got so confusedI had to write it down
-
Also when I turn off active low on both
x- and x home
y axis moves away from home switch
yellow light go out in M1 limits and m1 home diagnostic screen
and red overlimit led is now out on setting screen
-
I am not sure I am understanding what you have written but if I am it does not make sense at all
Changing the active state on one limit should have no effect on another unless they are not wired as you have the pins set.
Is there any chance you can trace the wiring from each switch and see where they go to on the breajout board?
Hood
-
before I start tearing this thing apart I have loaded Mach 3 demo
and my machines xml file ona Gateway running Win7 last nite....it did not run....
it was late and I quit....
I am going to spend some time trying to get Win7 to run
perhaps I got a problem at the parallel port...I noticed all
my led lights were not all lit green like they were on the diagnostic
page of the Win7 computer....just a thought.....I thought I remember
seeing a row of green lights all lit up before and now there is one out....
-
If I can get a screen shot on here I will send you one of the
diagnostic page to show you what I mean....
also, if I can not get the win7 to run mach3 in short order
I will go back to the XP computer and I will take the top
off that controller and see exactly how the wires are running
to breakout board for the axis motors....take a pic
It should be easy to see the way they are cabled...there is only
three of those magnetic switches on the machine and they share
the limit and home switch...Mach three somehow knows what the limits
are based on the configurations of the home switch....I think this is the way it is??
-
Okay here is the latest:
I could not get win7 to run everything looked good
I verified the com port address it is a 32 bit processor
so I quit with that after an hour...
I went back to the XP fresh this morning
I left ports and pins alone
I left just the way they were given in XML file
which was: X- and X home enabled and active lows for each
the same for all the axis enabled and active lows enabled
I then went to Homing and limits screen
x axis I reversed with home negative off
y axis I reversed with home neg checked on
z axis off with home negative off
the machine now homes and zero's out
and the machine now jogs at the right speed
before when all this was going on the thing was
just dragging in speed at jog
but now it has the right jog speed
Hood, I know you were following this at one time :)
what do you think is going on here
I never did take the cover off that controller
they used some kind of crazy screw with an uncommon head
I am not sure what kind of wrench is needed to take if off
it's not torx, not hex.....
If it was intended for a user to be able to change a fuse maybe sometime...
looks like they would have used a common phillips or something just for an access
anyway it is homing
but, I don't really understand???
sorry for the long email......
-
I have never used W7, not keen on it but looks like it may have had some sort of corruption or the driver was not being allowed to work correctly.
As long as its all working now then all is good :)
Hood
-
Yeah!
I wasn't in a big hurry to switch to win 7
I like XP just fine....switch to Apple
just about the time Vista came out
don't have any experience with Vista either....
I want to thank you for helping me out on
this.....
-
Vista lasted 2 mins on my computer, went back to XP. Have a laptop with W7 and I would format it and shove XP on but the boss wont let me as she likes some of the games on W7 ;D
Hood

hey let me ask...
why do I not have the cross hairs showing on my table display
like the support video shows....when a program is loaded according
to the video should be able to see the yellow lines representing the
x and y axis moving across the table display as you jog the machine
I have the soft limits set and the machine homed.....
I have watched the video several times must be missing something
-
Not sure, lines are not yellow now (you can change) but they should be there if code is loaded.
If you attach your xml I will have a look.
Hood
-
this is the same XML I sent earlier
-
Looking ok here with your xml, see screenshots.
Hood
-
What Mach version are you using? Maybe it is that that is the issue if you are not seeing it as in the above screenshots.
Hood
-
Mach 3 R3.043.006
-
Just downloaded and installed that version and it also shows the crosshairs with your profile so not sure why you dont see. Can you take a screenshot and let me see what it looks like on your toolpath?
Hood
-
this is shot of the program loaded
-
are the purple lines now in Mach 3 the cross hair lines
-
Yes they are purple now.
