Re: [Emc-users] Home and Limit Switch Setup in Stepconf
Thanks for the concise answer. I would agree that you don't want to limit the machine, as much as possible. None the less, I did have to compromise with the input pins. I think, I have a workable and logical setup as it is. Separate switches to home each axis individually and ganged max limit switches to prevent overruns. It cost me 4 input pins. I will start with the EMC documentation to figure out the format of the conf file and consider editing it. Is there further documentation on the wiki or elsewhere? When I am done and I have a working configuration I will post the file since my machine is fairly common. Chris John Kasunich wrote: Chris Barker wrote: Is it possible to edit the conf file manually? YES, very much so. EMC has _always_ been configured by editing ini and hal files. Stepconf is brand new in version 2.2, and is a "wizard" intended to make setting up simple stepper machines easier for beginners.

I don't know your actual pinout, but lets assume it is like this: Parport pin 10 = X axis home (and min limit) Parport pin 11 = Y axis home (and min limit) Parport pin 12 = Z axis home (and min limit) Parport pin 13 = combined X,Y,Z max limit All inputs are active low (low when on the switch) Then the limit section of your hal file should look something like this: # connect pin 10 to X home and min limit net X-home parport.0.pin-10-in-not => axis.0.home-sw-in axis.0.neg-lim-sw-in # connect pin 11 to Y home and min limit net Y-home parport.0.pin-11-in-not => axis.1.home-sw-in axis.1.neg-lim-sw-in # connect pin 12 to Z home and min limit net Z-home parport.0.pin-12-in-not => axis.2.home-sw-in axis.2.neg-lim-sw-in # connect pin 13 to all three max limits net XYZ-max-lim parport.0.pin-13-in-not => axis.0.pos-lim-sw-in axis.1.pos-lim-sw-in axis.2.pos-lim-sw-in Notes: Lines beginning with # are comments, you can put whatever you want there. Write something that will make sense to you when you are troubleshooting five years from now. Lines beginning with "net" create a HAL signal that connects things together. In this case, it connects a parport pin to EMC. Everything after "net" is on one line (my mail client is wrapping the long lines, and yours might too). "X-home", "Y-home", "Z-home", and "XYZ-max-lim" are signal names, and can be whatever makes sense to you.

Dean, If I got a report about these problems in 2.2.2, I lost it. Can you let me know what problems you encountered?

Re: [Emc-users] Home and Limit Switch Setup in Stepconf
I was just thinking that one possibility is I could not use the switches as 'home' switches. Just call them limits and manually home each axis.

Re: [Emc-users] Home and Limit Switch Setup in Stepconf
stepconf only gives a tiny, tiny subset of all the configurations that can be created through emc2's HAL. It sounds like your home switch configuration may be one that is not possible. You may be able to use custom.hal and/or inifile tweaks after stepconf has run to get the configuration you want, or you may be better off starting with a traditional stepper_inch/stepper_mm configuration and editing it to suit.

[Emc-users] Home and Limit Switch Setup in Stepconf
