In order for homing to work you must have the home input configured, even if it is the same switch or
sensor as one of the limit inputs, and you must have homing configured in Config > Mach under the
Homing/Softlimits tab. If you have Home In Place enabled, there will be no motion. The operation of
homing is documented in the "Mach4 CNC Controller config.pdf" manual which can be found from
Help > Documentation Folder. Look at descriptions starting on page 18 of this manual.
If one switch can mean both Motor0-- limit and Motor0-- home, then you should complete both
entries in the Config > Mach > Input Signals table with identical data.
You can confirm operation of your sensors by using the Real Time I/O display panel available by
activating it using the button on the lower half of the page at Config > Plugins > PMDX SmartBOB.
This will show what is being seen at the terminals of the SmartBOB without trying to understand
what the signal means. This panel can be move to a convenient spot on your desktop and left
open while you work on other configuration issues.
To see what Mach4 thinks the signals mean, see the Machine Diagnostics page..... Oops, it got left
off of the wxRouter screen set. You can temporarily load the wx4 screen set which will have the
Machine Diagnostics tab at the top. That tab will show a page with all the inputs, as Mach4 sees
them. Be sure to look at the ones called Inputs, not the Outputs. You can load the wx4 screen set
by using View > Load Screen and pick wx4.set from the list. When you are done you can go back
to the wxRouter screen by using View > Load Screen and pick wxRouter from the list.
If you need further help with configuration, please describe how your switches are wired and
post a copy of your "packaged profile" by using Help> Support > Package Current Profile and
save the file to some place where you can find it to attach to a post on this forum or to an email
if privacy is a concern.
If you are using the Touch module accessed from the button near the bottom of the screen, it
will open a window with controls. At the top left corner of this window you can access Help > Docs
for information about how it is intended to work.
I do not understand your question about X and Y offsets. You will need to ask on the Mach Support
forum for assistance with that. See:
