I'm having a similar issue but it's after a print.
Having an issue when a print is finished on my cr10s and I go to re-home it doesn't recognize the EZABL pro/zstop and just slams the bed. I am using the EZBoard and EZABL pro with the current version. Before the EZBoard I did not have the issue. Everything works fine on the first print and homes like normal it's not untill I finish a print and go to start another print.
