So basically, it gives you a LOT more control over your tolerancing. If your bit has been reground and it’s actual dia is 0.245 and not 0.25 the machine compensates for the change. (Note: most software already does a form of cutter comp but it will be to the stock 0.25" not the actual dia)
For people like TMToronto I am sure this is a huge change.
The also comment about G54.1 … So it appears the Masso G Code dialect goes the “dot” route unlike Haas who add higher numbered GCode. For example, Haas supports a G254 (Dynamic Work Offset,TCPC) vs Masso’s approach of “Rotated Tool Center Point”.
You do know this is a little bit of knowledge that I am gaining from a community college class. We just played with G254 for the first time yesterday. So, my confidence level in what I am saying is not terribly high.
I will say these post’s just go to how powerful the G3 is and getting better.
I obtained my G3 second hand because it did not support cutter compensation from someone that purchased a converted machining center that had the G3 installed. I don’t know that I will ever have a need for cutter compensation but good to see they’re listening to their user base and adding features.
Need is of course a relative term. Frankly for wood and other materials the Buildbotics is just fine. That controller does not have the same bells and whistles as the Masso. In the class I am taking which I admit is 99% Haas machines we are expected to hold fairly tight tolerances.
When you are trying to shave of error in a part every little bit helps. Whether that is reducing runout, cutter compensation, backlash whatever … so cutter comp is another tool in the toolbag
