Need help with setup config. Cant get mill to home was created by MAG45
Just updated LinuxCNC and had to do a clean install as I was on ubuntu 10.04. Trying to do stepcnfg wizard using the same settings I had written down from my old config. It will not home anymore, I have tried adjusting several settings in the wizard to no avail. It goes to the home switch, starts to back off, then errors with 'home switch active before latch move' I have spent the better part of the day trying to find answers but I dont understand linux well enough to understand what i am reading and if it even applies to my issue.
I am running from a parallel port through a BoB to gecko 540's, have micro switches for limit and home, they are set up as n/o which i know is not how they should be done, but they did work this way before.
Thank you for any advice

Have you tried just using your old configuration?

Yes, i had everything written down from my old stepconfig and re-entered those values. One thing i thought of is that I had somehow added a backlash adjustment before, but i dont recall how to do that, and im not sure it would help this problem.

He wasn't asking if you tried to use the settings from the old config to make a new one. Use the actual old config files copied over and try to run them. They usually work perfectly well with the new version as is, or with minimal changes.

Nice, i used to do the 3800 swaps in them before health issues slowed me down. This machine im trying to get running made a lot of the parts i used/sold. So many Fiero owners have asked me if i still make them, part of the reason im trying to get it running again.

Too, bad you didn't back them up first.
Do the HOME_SEARCH_VEL and HOME_LATCH_VEL have matching or opposite signs?
You might need add a little debounce to your limit signal or maybe try increasing the home latch velocity. (more as a test than a solution)

I know, They are equal.
Could you explain, how/where to add a debounce signal? I have read some on it, but its still unclear to me.
I am attaching the ini and hal files

Before you try the debounce try inverting the home pin and see if that helps.
net all-home <= parport.0.pin-12-in-not
