Is it possible to use stall force tolerance for z axis home and detecting the sheet metal in qtplasmac?  I will add a floating head and a z home switch if its not possible.
 

I'm not sure that could be done using analog without writing a custom component, but I'm no expert on analog.   In my experience you want some kind of floating head so that if the metal tips up or something it will stop the machine plus you can use it to probe the work height.  I haven't tried it yet but you can also do ohmic sensing to detect the material + float as backup.

Hi kn612,

Were you able to get motion with your analog servos as well? PCW was kind enough to send me a 7i97t for testing as well. I will make a pull request to add it to 2.10/master when we confirm it.

Yes, if the input common is a + voltage, those are sourcing inputs.

( it's easy to get confused as sourcing inputs connect to a sinking drivers and vice versa ) 
 

hi i am on the same point... could you share your solution please?
