General Mach Discussion / Lathe CSS again

« on: January 25, 2017, 09:51:55 AM »

I've done a lot of searching on this, but cant find a straight answer.
Does CSS work with FPR?
I cant get it to. I have to use FPI. Is this right?
I found a lot about how to use CSS, but not a lot about the feeds.
I'm cutting 6061 aluminum at 600css with a DOC of .1", and a feed of 10 to 12 IPM rough, and 6 IPM finnish.
It's working, but isnt it wrong, because of the diameter changing size?
Shouldn't it be FPR so the relation of cutting feed matches the speed?
How do others set their feeds for CSS?

I have the latest Licensed Ver. of Mach3 on a 2016 Shopmaster, using the Lathe.
Thanks

General Mach Discussion / Do i have to manually type in tool # when I do tool change?

« on: October 04, 2016, 12:00:37 PM »

I'm new to Mach3, and new to cnc lathe. I've been using EMC2 (linux) on a mill I retrofitted for about a year.
My question is why do I have to manually input the tool number after each tool change? It's very easy to forget that small, but important step.
The tool number is in the program_ M6 T4 etc., but Mach always goes to tool #0 before each change, so the offsets dont change until I type in the tool # and hit enter.
Am I doing something wrong?
I've looked this up many ways, but cant find this issue anywhere.
Thanks for any help

Post Processors / Featurecam 2012 post for mach3 turn needed

« on: September 10, 2016, 05:02:14 PM »

Hi. I'm getting a shopmaster next week that comes with Mach3 installed/configured.
I'm learning Mach3 before it gets here,  and i have access to featurecam 2012 without support, tho.
I've tried all the posts here, but none are working, can anyone share with me if they have them?
I like featurecam better than other turning cam I've tried.
Thanks for the help.
