Masso Beta software picks up cutter compensation

They just released Beta adds Cutter Compensation (G43) ! Now I would not run this Beta for a while, but it is very good news.

For those who don’t know what cutter comp is:

Cutter Compensation: When and How To Use It - Practical Machinist : Practical Machinist

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.

Hey Carl and Lynn,

do you mean Cutter Radius Compensation (G41, G42)? G43 is Tool Length Offset (G43) (according to the Official G-Code Standard3.5.11 Tool Length Offsets – G43 and G49 vs. Appendix B. Cutter Radius Compensation).

You omitted the link to Masso!

This is how it’s explained if you use LinuxCNC:

Yup typed the wrong G Code duh! I guess I was too excited.

Here is the Masso Link:
MASSO G3 - v5.100b (BETA) Release Notes

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.

Hey Carl and Lynn,

yes, Masso obvously tries to become more and more a professional CNC controller. Question is, as Derek @WaywardWoodworker mentioned, what do you need.

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
