Cut my first part with the free G-Simple software and my new z axis today. For a first attempt it isn't at all bad.
I'm sure G-Simple has been reviewed to death on here but it seems only fair to say thanks and that I am most pleased
My aluminum pulley box came out .06mm (0.0025") overlength. I pressed that bearing in and it doesn't want to turn, but hey, it went in and tight is much easier to fix than loose.
Slight chatter from the finishing cut in the pocket which cut down hill. No chatter on the outside, which cut uphill, but it didn't remove all the previous cut marks. OTOH the front came out almost mirror so it is possible, I just neeed to tweak the parameters a bit.
But these faults are mine, what about the software?
It seems totally unfair to criticise free software, but if it was all singing and dancing he'd be asking $ hundreds for it. Let's be grateful for the few shortfalls that mean the price is definely right
G-Simple does part of the shape at a time. On this part it cut the outline, made several horizontal passes to clear the rest, then repeated the same going progresively deeper to depth. Then it started on the pocket, there is little, if any, optimisation. OTOH the code worked flawlessly so I wasn't bothered when the wife called me to eat dinner, I just left it running, nil problemo.
When you import a dxf it doesn't seem to notice elevations and thicknesses. You define a rectangular starting block then raise bulges and maybe sink pockets into them. When I wanted to use the same dxf entities in two pockets/bulges I found I had to copy them off to one side so I could pull then back in to use again. This is not a complaint, merely an observation.
Top tip: If you want to try G-Simple read the manual then look at at the worked examples on their web site before you do anything else. It's the examples that make it simple
