Drilling cycle with pecking crash

[ronenbu]

Hi, loading the following file into UCCNC, and starting the cycle, the program pointer immidiately jumps to the last drill position, skipping all others, run this once and crashed my drill bit and scrapping the part ( if I remove the last position (line Y191. before the G80, all works well... wierd)

Hi,

I've just tested your code with the latest development release version 1.2110 and the issue does not occur.
Since 1.2106 is an old development release which had lots of problems and never went to official release therefor we will not investigate that version.
I advice to install the latest official release or the latest test release.
