I just finished uploading and testing and it works great, just like I was expecting it to.

In the configuration.h tab there is a section for endstops.  Just go in there set invert Z to true or the opposite of its current setting then upload the firmware with the new setting.

It is the one I installed when I put this all together.

The printer sees the trigger, it just sees it in reverse.  How would I change that in the firmware?  I'm a newbie here and have not done much with the firmware besides load it.


What kind of printer is it, what kind of mainboard is it running on and do you happen know what firmware it is using? Better yet do you have a copy of the firmware already as in have you upgraded or flash it to another version?

recently purchased some optical endstops.  I tried to hookup one on the z axis, and it works backwards.  The led is on when nothing is blocking the optical device and the reverse happens when it is blocked.  To use this as a z axis home switch it would have to be blocked until it got home then have a small space to stop and reverse the axis.  Is there something I have done wrong or not done, or are the endstops not suitable for this purpose?

The question is does the printer see it functioning the same way. Depending on the manufacturer the LED on the endstop has a different purpose. It can mean it is open or closed. What you have to do is see if the printer sees it triggering when it should. If not then you have to go into your firmware and invert that endstop.
