Hello Frederick
Yes it worked. Thank you.
Maybe it didn't work because it's still at the endstop-triggering position and prevents any movement. I just misread ''terminate'' -> it seems it means both directions
"H1 terminate the move when the endstop switch is triggered and set the axis position to the axis limit defined by M208. On delta printers, H1 also selects individual motor mode as for H2. Normally used with relative motor coordinates (see G91)."
