Too bad! The difference, expecially in Aluminum, between climb and

Yeah, I got bitten by going the 'bob' route too. Never again!
What I like are what http://www.vectric.com/ have to offer and their prices
are good compared to the ease of use and number of features they have.
They have a trial software download to test run it first which is nice.

Yeah, I know about those! But, those numbers were for mild tool steel.
For aluminum,
the strategy is a bit different.

Okay, I got the idea the original question was about some hard work
material.
But, if it is Al, then there are a bunch of things you can do. Taking
light cuts
with high feedrates has always been very helpful. You want to keep from

Hi John,
Regarding calculating feed and speeds for tools, we do not have this feature at
the moment, but it is planned.
Good question about the video’s, I will add that facility.
Do you own an EMC2 controlled machine?

The kernel needs kexec support; if you use Ubuntu, it's compiled in already.
You also need kexec-tools.
If you built your own kernel, you can try to enable part of acpi instead of
using kexec and a second kernel - see the responses to my message on
EMC-developers.

I ran your test code and sure enough when G64 is modal the way you program it
will cut the
corner. A couple of things to keep in mind when programming g code.
Always retract some distance above the material before doing a lateral move. I
usually use
.25 above the material as a safe Z height.
Is there any facility in your software to calcualte feed and speeds for tools?
I find this feature
very helpful.
I have four different commercial cam softwares and one is not very good and one
is much
more expensive but somewhat limiting in areas where I feel I should have
complete control.
I would gladly sell you my copy of BobCad for 1/2 of what I paid for it and use
the money
toward a copy of SharpCam.

Well of course we are biased and think our product is better! Download both and
try for yourself. If you have any questions please do not hesitate to ask.
