I Found this site but I am not sure if mach4 hobby can do custom macro B

If so maybe someone can help you with it

Hi skunkworks

I'm not sure on Mauri's file.   I don't think he had my stp file yet if you look back he posted that before I sent over the file so that maybe something he drawn up

Hi Mauri
I did some more playing and I have 3 settings for the rotary see attached pic.  I also attached 2 codes I believe that the units/min is what you normally use in mach3 and then let it to the feed rate correction and I also attached the deg/min that may work for you but I'm not sure I think the cam is doing the correction for you instead of the control doing all of the thinking it maybe worth a shot.

Hi Mauri
Attached is a .stp file for you to test with.  also I had the feed rate set at 6.4176 IPM for the tool but it will take all the exact settings to make the feed rate match 100% since it is a time factor feed rate if that makes cents to you

Hi Mauri
sorry the pic can from Mcam I never looked at it in mach at all but that sounds like what it will look like since the mach toolpath window only shows xyz and does not have A axis/or any rotary in the window.  I was Just wanting to help with the G93 in this part of this forum topic and to say I use it in our 5 axis waterjet and it works. 

I'm sure your cam should be able to post a g93 code in mcam all I had to do is change it in the software setting they had three ways to post feeds on a rotary axis

Did some playing around   But first what cam are you using?  I did some testing on mcam and it looks like it will do a 4th axis feed rate correction and also I posted out a G93 code for you to view see attachment

Attached is two file one has the G93 code that we need to run to make the feed rates right and the other has the normal feed rate.  Like I said this may not help you much since it is not a mill code but you need to have the G93 when you do any rotary movements as you can see in the code  and in the picture that is attached when it is doing the straight line I do not need the G93 but when it comes to the Arc I do

I wish that would work in my case be it would not the radius that we are cutting are always in one part is always different and our rotation is around the z axis and then throw in a tilt of the head that also is in deg's the g93 is the only way for me

Hi Mauri
I use g93 on our 5 axis Waterjet and it uses it only when the one of the two rotation axis's  are being used but the is also x and y movements all on the same line. I will try to remember to post a code for you to review but it may not help you much but I had to do a lot of digging to help Sigmanest get it to work right.  Also I do know on my machine with mach3 the arc movements we had to divide the feedrate by the arc radius not sure why but that was the way it worked out

The G17,18,19 only has to do with arc movements. To do what he wants with the z axis is to use G93 inverse time that will make all axis to be at a point in space in a certain time frame.   Most cam software can do this in the post   And as far as the tool path window goes it will be hard to se 4 and 5 axis tool paths but then again on my 1999 haas control all I see is code so at least Mach has something to look at
