Trochoidal Pocket & Profile MOPs plugin (HSM)

Hi qwerty

Hi, is the following a bug or a feature?

--> Neither.

Trying to understand this behaviour / inconsistency. -->

  It’s normal behaviour.

The Troc mops are not ordinary mops (where a 0.5 stepover gives you a 0.5 stepover)
they are fitting routines, (fitting crescent shaped) toolpaths to the available area.
So they fiddle with the stepover to do so, if you look at the side bar info panel you’ll
see there are a lot of extra parameters to twiddle. Just above the stepover parameter
is another parameter called minimum stepover. With these two parameters you can
modify the stepover value. In practice I’ve never had to do this though.

If you have an already existing job where you are using a pocket mop and it’s taking
too long then start a new thread and post the CB file, and I’ll walk you through the
process of converting a pocket mop to a Troc mop.

Dave, thanks for explanation. I use troc mops on regular basis and I am aware of minimum stepover / stepover parameters effect. I was just wondering what is going on. After generating toolpaths I will measure actual stepover and adjust parameters to get actual stepover I want...

I like the Troc mops as they have speed and utility and I use them where
I can, for my purposes pocketing HRS and Al plate and some plastics I set
up some styles to make it quick and most of the time just have to enter
the target depth.
Mostly I use the Troc rougher along with a standard CB profile finisher at full depth.
This ensures that the final dimensions and finish are good and a profile mop at full depth
to clean up the pocket walls is fast.

Yes, trocho pocket rough MOP + profile finish MOP is also my best practice...
