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](https://www.practicalmachinist.com/videos/g-code-tutorials/cutter-compensation-when-and-how-to-use-it/) 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, > [@CandL](#): > > They just released Beta adds Cutter Compensation (G43) ! Now I would not run this Beta for a while, but it is very good news. do you mean [Cutter Radius Compensation (G41, G42)](https://linuxcnc.org/docs/html/gcode/g-code.html#gcode:g41-g42)? G43 is [Tool Length Offset (G43)](https://linuxcnc.org/docs/html/gcode/g-code.html#gcode:g43) (according to the [Official G-Code Standard](https://tsapps.nist.gov/publication/get_pdf.cfm?pub_id=823374) – _3.5.11 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](https://linuxcnc.org): - [Cutter Radius Compensation](https://linuxcnc.org/docs/html/gcode/tool-compensation.html#sec:cutter-compensation) ---

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](https://www.masso.com.au/masso-g3-v5-100b-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
