Limit error

If you are using Axis as your Linuxcnc screen, click on the machine pull down menu and there it is. I can't say for sure where to find it in some of the other screen choices.

Okay, i found it, but not really sure what im looking at. Im guessing i need to reconnect my limits and switch them on and off to look for a change on one of the parameters.

Okay, so i rewired the E-stops, but dont think i got them right, but i did get it to run. My limit switches are also my homes, luckily the 3 on the home ends are working. So I was able to home it and actually run a warmup program. But theres a new issue that strted when I reconnected the limits. I ended up connecting them all to the same pin on the BOB, But now the computer wont boot linux if the parellel port is plugged in, it just freezes up. If anyone can give me a clear diagram of how to properly wire my limits to the BOB that would be a big help.

Ignore, double posted

I am confused, easily done, about what you have connected.
You say your home and limits are shared and homing works, but then that you connected them all together.

Limit switches can be chained together in series so long as they are NC

Home / limit switches need to be connected individually to 'xhome /x-max-limit' or whatever, there are options in stepconf to do it.

Unfortunately it sounds like your parport may be fried (albeit given the history I might be rather suspicious of the BOB too)

Is your CNC machine powered when you start?
If you have a powered BOB with opto isolators, having it connected or not should make no difference if it is not switched on, nothing should get through.

The pins should be in an indeterminate state until a driver has claimed it and if having something connected to it prevents booting, that is not sounding promising.

One option would be to buy a PCI parport card, possibly a twin port one to give future expansion if your onboard one turns out to be U/S.
A later netMos one should work without problems

It will be useful for expansion anyway and will comprehensively determine if your existing port is gone .

I am unsure how to tell on the BOB which connection goes to which pin. I have 5 switches, 1 for Z, 2 for X, and 2 for Y. If yo look at the pic of my BOB wit the 6 terminal connector on the left they were originally connected to 2,4,5 and 6 common. I didnt pay attention to which went where when I pulled it out. I tried to connect it back that way not paying knowing if there was a proper sequence. AXIS didnt recognize them, when you press a limit there is a visual sign on the "DRO" of axis and only Z limit was recognized. So I connected all of them to terminal 5 but now only 3 work and the PC wont boot unless I unplug the parallel port cable, plugging it back in after linux starts.

Nothing attached.

What is the make and model of your BOB and please attach your config files (ini and hal at least or just zip the whole dir)

It is a PminMO 4x072105a

I will have to try and figure out how to get the config and hal from linux later when I go out to the shop.

Okay, hope this works, and yayy me, first time ever posting from a linux PC!

Oh, and those are changed from my original config on the limits to make it function as it is now.

have you read this?
