Lowrider V4, Z crash on pause

Just completed my first air-cut and on trying the ‘pause’ option on the touch screen I found that the z axis crashed, steppers disabled. Repeated another three times, with full reset, new g-code and z axis crashes every time. I checked Estlcam which I used and there is no specific ‘pause’ or stepper disabled in the code for a pause function so presume there is a steppers disabled selection active in Marlin for the ‘pause’ function?

Has anyone else come across this issue and is there any other way to correct without rewriting firmware? I am running a skr 1.2 pro with tft 35 and loaded the latest v515, version 2.1.1 of firmware from GitHub.

There should be a cut and a hold current. Estlcam should not normally disable the steppers, but I am not sure since I didn’t wire the ENA pins. -_-
