Re. workaround - thanks - I'll give that a try (a quick look at the generated g-code looks good).

Re. rapid/clearance heights - thanks for the info... that'll probably save a few cutting bits, although I'm still in the what-am-i-doing phase, it's probably a good idea to get into good habits earlier, than later.

Many thanks.

Hmm, I can't see the attachment even though the forum software confirmed it's attached. In any case, the content of the job file is

Newfangled Mill Wizard / New user, confused by feed and plunge rates

« on: January 02, 2014, 05:35:20 AM »

I bought/registered MillWizard today, having taken a step into CNC over Christmas, and wanting a SIMPLE utility to allow GCode to be quickly and easily created.

I've created a project to cut a rectangular shape from a piece of perspex, thinking that I'd created suitable feed and plunge settings (800mm/min, 60mm/min, respectively). What happens with the generated g-code is that the feed rate is set correctly for the plunge, but never set again for the x/y feed, resulting in a very slow x/y feed into the work (which, with perspex, is likely to burn the stock material). G-Code extract given below with the plunge feed-rate highlighted (*****) :-

(MillWizard 1.0.13)

Any clue as to what I'm doing wrong?
