General Mach Discussion / Re: How to make cnc work?

« on: July 10, 2017, 09:09:59 PM »

I know nothing about the Alibility Systems Controller and don't use
MecSoft Software. Since you don't have a manual I will not even try to guess
what you have. I will not spend time looking for info that one should provide
so hope you understand.

Mach 3, a software controller, uses gcode to give the necessary instructions
to the drives so the motors can move properly. There are different dialects of
gcode ( just like language )and different controllers use different dialects
of gcode. CAM / Cad software generates the gcode for something to be machined
and usualy there ia a specific post processor for a specific contoller.

Mach3 will work with a computer that has a parallel port available provided and
the PP is capable of providing a quality signal to the drives. It can also use
an external motion device designed for use with Mach3.

Hope the above helps,

Change the feedrate of the indexed moves in the gcode?

Bravo1,
I would suggest that you use a slow probe rate as that will minimize the overtravel.
It's very small at a slow  feedrate. Here is link to some probing info:

http://www.machsupport.com/forum/index.php/topic,35226.0.html

Now on the practical side, I doubt very much that you can even measure the overtravel and the overtravel
amount can vary and is dependant on the accuracy of YOUR system. I'll add that with small diameter drills
a top quality chuck and alignment are required.

Check  / adjust the drive amp setting according to what the motor manufacturer recommends.

The attached sheds light on the influence of feedrate and acceleration when probing.
Just something you may want to consider.

General Mach Discussion / Re: Lathe Threading. Fantastic but just need one final answer. Sorry, two!

Happy that it all works for however you work.

Not a soap box... just some thoughts about threading:

As an engineer you know  the  importance of proper application of standards and the required tolerances to create a properly fitted bolted or screwed joint
and how the standards can be used in the manufacturing of components.
 
Most folks just machine a screw and the nut goes on and life is good. Life is good, they are happy, so am I for them if that's what they want to accomplish!

Code defines tolerances, my writeup just makes one aware of them and address why one may not achieve the tolerances.Threading was screwed up for a long time
and and working with Art we were able to fix it. We had to achieve lead tolerances and FIG 4.4.5 gives the basis.

What most folks DO NOT know is that calc's are done and there is a lot to designing, specifying, and getting the proper components to meets specifications.
They don't care, the nut goes on! You can't take that approach if your presenting basic threading information.

Thoughts from a process / mechanical engineering designer,

RICH

The lathe is different than the router. Frankly I think it is more complex because of the tool geometry and all that goes with it.  Also the screen set is different and has additional buttons and DRO's. Yes, one may find a certain way that things
turn out ok. Like Clint said " Tell Me, feel lucky today". 

Have fun,
