Pause at height not working correctly if more than one pause needed U4.9

[iPa 3]

Hi,

I tried to insert two "pause at height", at 4mm then at 13mm.

But the script has inserted this two sequences consecutively at 4mm (at the same place) in the gcode file.
13mm script was executed the first at 4mm, immediately  after the 4mm script was executed!

It certainly is a mess.

I knew that Pause at Height using "At Height" is sketchy if there are Z-Hops in the file (a well documented bug).  What happened to you seems to be have been caused by Z-Hops and another peculiar thing.

I think what happened is that the first pause was inserted OK but the second saw the already inserted Z values of the first pause and so it added the second pause right there.  The two sets of pause code look jumbled/intertwined/just plain weird.  I think the search during the second pause routine saw the line "G1 F300 Z15" within the first pause code and so the second pause routine was inserted there as it was greater than the search number 13.

Pause at Height works fine if you use "By Layer" because the search criteria is very specific.  My suggestion would be to pause at Layer:19 and again at Layer:64.

I tried to use "By Layer"instead of "At Height" and  it works perfectly !

Thank you @GregValiant
