OK, but your code did not contain any feedrate, so I've tested with the default 6 value since you did not post the feedrate in the code.
Anyways I will check the code with 600 feedrate and also using your profile, but I can do that only sometime tomorrow, because it is night here and I'll have to go now...

You are right, I removed too much of the code, even the initial feed rate setting.
(But my own UCCNC still had it as the last feed value, so I did not notice.)
I corrected now.

I suspect this discussion is related to this thread (possibly) can I suggest cnv have a read and consider the thread

Thanks Robert, at first glance, this appears to be exactly the same issue.
(I tried to find similar thread before starting a new one, but did not succeed.)
