If your step over plus your tool diameter is greater than the space between features then it will not go through that apace..

We never have the time or money to do it right the first time, but we somehow manage to do it twice and then spend the money to get it right.

Hmm, baffled now, i presumed it would be slotting that gap?

Just tried reducing the step over to 0.43 and full depth (2mm) and it makes no difference.

It does not look like its connected with step over - the 1st tool is 10mm and it happily passes through a 10.15mm gap.

One big difference is that the 1st path is standard, the others are "rest" machining????

In fact its worse than i thought, there is a lot of unmachined area, see the "u" in the picture attached - it just cuts two small areas inside and leaves the rest.??

That would explain the short run time a bit.

Very odd

Ok, i'm clearly not getting this ;)

It seems i need to be using 3d Adaptive paths, these have rest machining as well.

Tried that and as the tools get smaller it adds an ever increasing workload of finer and finer paths where it tries to perfect the previous path, this adds hours to the time so is pointless.

Trawl the 'tube and mr NYCNC had it but "fixed" it by making stock-to-leave+tolerance bigger on each tool - this may work for two tools but i have 4 and by the time it gets to T4 i am leaving 0.43mm of stock - this means too much for a cleanup pass with the 1.5mm tool at the end.

Baffled now, i did not think this would be so advanced.

Ok, never mind, i'm binning this project as i've spent far too long on it and got nowhere :(

I also see some of the letter spacing is too close for a 1.5mm tool but there is no way in F360 to adjust that and importing text into F360 is full of bugs too. Clearly not the app for engraving even if it is "mill" engraving.

I might have a play with aspire but have to fix a new post as that app is tuned for my high-speed setup.

Hi
