QuoteMoriquendi Hi Phil, It would appear that you've found an issue with the PP20 and the MKSbase, 3.1v should register as a logic high but perhaps there's more hysteresis on that pin or some form of protection that's interfering. I haven't used an MKSbase but I have been using a Smoothieboard for a couple of years and it doesn't have this issue. Idris Hi Idris, It seems like my PP20 board isby funhouse - General

QuoteMoriquendi Are you using a PP20 board (single piezo connection) or a universal board (three piezo connections)? The Universal v2 kit board is active low output, that means that when triggered the output drops to a logic low voltage, somewhere around 2v IIRC. The output pulse is very brief, around 0.3 seconds long, it's very unlikely that you will be able to see a triggered output with M119.by funhouse - General
I have a question about the output voltage when the piezo is triggered. I've installed a Precision Piezo kit into my newly built Hypercube Evolution. It's running an MKS Sbase controller with Smoothieware. I initially hooked the output into the Zmin port which is running at 5v and successfully controlling the other endstops on the printer (optical type). I wasn't able to get the piezo endstop toby funhouse - General
