General Mach Discussion / Re: Mach3 behaving strangely

OK,
Sounds like you guys are on to something here. Please help me set up my machine correctly.

I have A slaved to X because I have 2 motors on my X axis. However, I currently have only 1 home sensor on my X axis. What I will do (I have ordered the parts) when I get the parts is have 2 home sensors on 2 separate inputs so that I can "square" my gantry with a homing routine.

But, currently I have only 1 home sensor for the X. I am confused about slaving, when I first set up my machine I slaved A to X and the machine would jog via the keyboard normally, BUT, when I clicked ref all home only 1 of the X motors would run and the gantry would try to twist until it stalled. I posted a question about this on another CNC forum and was told to check "Home slave with master axis", this seemed to fix my problem because now both motors run when I home. But it has caused this issue.

So what am I to configure to get it to run correctly  with the 1 X axis sensor that I have now?


What am I to configure when I get the second home sensor  and  i want to square my gantry with it?

Thanks guys,

Scott

I also have 3 home sensors that are NPN type all wired together that land on 1 input to the G540. These produce an input on pin 11. My machine homes all three axis and then stops, so I think that it homes successfully.

Thanks to you guys for taking time out for me.

I have 6 limits, 2 per axis all wired together normally open, any limit will produce an input on pin 10

I have additional information about my problem. When I first start up mach and my machine I can jog via the keyboard and trip a limit and the machine will stop instantly and require that I reset it. It will then reset as it should and continue to run and continue to stop when I trip a limit. BUT, if I click Ref All Home then mach will not stop when a limit is pressed. It will home normally, but after the home is complete it will not stop if I jog via the keyboard and trip a limit. I can open diagnostics and see that the limits are tripping but mach ignores them after a home routine. I am running the stable release of Mach demo. The only unusual setup that I have is that all my limits are wired normally open and all of them come into 1 pin on my G540 drive.

I have attached my XML file.

My computer specs;
Windows XP pro service pack 2
pentium processor 2.79 GHz
640 MB of ram

I am running no antivirus, this is a new clean install of windows and this machine is not connected to the web.

Thanks for any insight, I am really stuck here.

Yes, I can be jogging and looking at the diagnostics and trip one of my limits and it will illuminate in Mach. I have all six limits wired to one pin input. In diagnostics, all six limits will come on when I trip a limit but Mach ignores it and just keep on jogging. I have re-started Mach and restarted my computer several times.

I have a new install of Mach3 Demo to set up my machine. I have configured my travel limits to all come in on 1 port pin because of limited inputs from my breakout board. This works fine, for a few minutes. Here is the situation, when I first start Mach and begin to jog my machine if I hit a travel limit the machine stops and tell me in Mach that a travel limit has been tripped. I reset Mach and all is well. However, after jogging a few minutes the travel limits no longer stop Mach from operating. When I go into diagnostics I can see that the travel limits are in fact coming on when I press them but Mach continues to run. This happens every time I start Mach after about 5 minutes of machine motion.

Anybody know what could cause this?


Thanks,
Scott
