run the "com stress test.cnc" program after you get homing working.
also what kind of switches do you have? do they OPEN or CLOSE the input when triggered?

Will do. I just got the home to set.
My switches OPEN when triggered.

My limit switches worked when they were set up as limit and they worked as home switches when configured as home as well. But when assigned as Home/limit they only act as home and will not stop movement when triggered. Any ideas?

post a fresh report.zip so we can see your current setup.

how did you test that, do you mean they don't stop motion while homing, or after homing?

if they don't stop motion while homing then you have them wired or assigned to the wrong input. use the Alt i menu to easily figure out which switch is wire to which input so you get the home switch input assignment right to match the homing direction.

I did that but I will check again. I used Alt I and the LED's on the board and then checked the Wizard,
Also, I am having trouble assigning Dwell in-between movement lines. I started to try Fusion 360 for my CAM and I have it moving in simple shapes. But is there an easy way to edit the processor code to add "writeBlock("G4 P1");" Having my machine pause is critical.
Thanks,

yes, you can edit the fusion post, i don't' use fusion, swissi is the fusion expert here and im sure there are lots of other resources online telling you how to edit a fusion PP.
we just took the time to double check homelimit inputs on an acornsix and i can confirm that the switch input acts as
a limit switch before homing
a home switch during homing
a limit switch after homing

I use RhinoCAM for most of my machining and im just experimenting at this point with Fusion. But i am using the Centroid.cps processor thats inside of Fusion. Since Fusion had it i decided to try it, but it seems the code mod would be inside the Centroid post processor. At least thats what the AI overlords say
