You don't have to assume that Mach3 is reading that line of code's feed rate as inches/MM per minute. It is but that is where G93 would control the AC axis in degrees per minute

That's not what I meant. I thought maybe the xyz move as in sqrt( x^2 + y^2 + z^2 ) was dictating the speed of rotary motion. I still think the way it's mixing the motion is messed up.

Maybe g93 works for head head by setting offsets? But at the moment it doesn't make sense to me what it's doing with the fword.

Ah. That's why.

Ah. That's why.

Hi there Micheal,

This is definitive answer I needed.... thnks for that...


also Re:

"Dan:

As I recall, it was some time after Rab’s fix was done that G93 was implemented..afaik it was implemented well and works fine in m3.


Art"

Rab did mention to me that it was some time ago that he last looked at this..... However, from Micheal's found info it would seem that for rotary use.. the 'fix' he came up with at the time.. remains the most usable / useful....

This is not to say I won't include the option for g93... at some point the Mach 3 bug will be fixed...

I don't understand why people are having problems with Mach3 as far as g93 goes, it works fine for me.

The real problem I am having with ver 107 toolkit is that it is outputting two F word per line in some spots

and Mach3 does not like this. Below is some 5 axis gcode that I generated with a commercial CAM package

and seems to run fine with Mach3.

I don't understand why people are having problems with Mach3 as far as g93 goes, it works fine for me.

The real problem I am having with ver 107 toolkit is that it is outputting two F word per line in some spots

and Mach3 does not like this.

Hi There,

My only problem with g93 and Mach 3 is weather or not to go for a direct implementation of trunnion 1.07 .. or to go with the pre-g93 version...

that's it.. don't use trunnion myself.. or g93....

Any rotary axis work I've done with CNC_Toolkit has worked pretty much fine withoutg93 However, I am not scripting for myself at the moment.. or my own use... so if it's generally felt to be a useful feature then I want to include it.... unless it's more trouble than it's worth....

For me, the feedrate is the biggest issue. I broke an endmill the first time using G94 because as the toolpath changed it ramped up in speed when I did not expect it. Now before every run I sit by the program for an hour manually changing the feedrate each few lines. Its a real pain.

I am using an older version of mach3. Its an old computer dedicated to the mill without internet access. I'll have to try the newer version.

Yeah the double feedrate is just because I wasn't sure how to go about changing that in the post yet. You must also be careful not to forget to remove the first and last line with x0 y0 z0 and any lines with an F0.0 number.

[billw999]

Lines three and four still have two F words per line

[MichaelGolden]

Lines three and four still have two F words per line

Yeah oops. I quickly generated that one. It's the file I was testing yesterday. Just remove the first extra fword in the line.

[billw999]

It runs without any problems that I can see.

For anyone trying to generate toolpaths with Gmax and cnctoolkit there are a couple of things that I could find no mention of

in the manual, one the surface you are projecting the splines onto need to be above the 0 plane, and second the imported DXF

file that you are projecting needs to be subdivided or it will not lay on the surface right.

Hi There,

" the surface you are projecting the splines onto need to be above the 0 plane"....

NOT true.... as long as the spline for projection is above the mesh then you can project just fine... I've just tested it now to be 110% sure...

" the imported DXFfile that you are projecting needs to be subdivided"

The advice in respect of appropriate subdivision in my ebook applies to ALL shapes.. and is stated as doing so quite plainly.... so I would think that an imported shape is just another type of shape.. and doesn't need any special advice.... it's a shape... treat it like one...

Hope this helps

Hi There,

" the surface you are projecting the splines onto need to be above the 0 plane"....

you can project the splines but when you generate the toolpath it does not stay normal to the surface unless you are above 0.

This shows the results I get above and below 0.

UTTER RUBBISH....

by 'doesn't stay normal to the surface' I take it you mean... incorrect angle vectors when the toolpath is generated....

You are below the origin... so 'angle round origin' will obviously not produce correct vectors... but this has absolutely NOTHING to do with PROJECTION... just means you didn't think about the toolpath angle options... before you made the toolpath... other settings WILL produce usable angle vectors....

This basic problem / issue / misunderstanding.... show's me you are missing some fairly important info / appreciation of the basic principles... re: toolpathing with CNC_Toolkit....

If I used Angle from origin what you said would make sense, but I used Angle from Reference surface.

Hi There,

again.. this is what I mean.. about missing something important...

Angle round reference surface is very much dependant on the surface... the level of sub-division.. AND the location in the scene..... If incorrectly located.. angle from reference surface will pretty much always give incorrect vectors...

BUT... This has absolutely NOTHING to do with projection...

It's about understanding how CNC_Toolkit derives and processes vectors BEFORE hitting make toolpath.

Perhaps I should be a little clearer...

You can project anywhere in the scene... as long as the spline overlays the object.. and you're selected projection method is appropriate...

Angle vectors are not involved at this point.....

You can then locate the spline / object anywhere you like in the scene... and process the spline to toolpath... depending on scene location... different options produce different results... even when you might think otherwise...

Angle processing does not come into play.. until you press make toolpath... at which point cnc_toolkit attempts to calculate angles to suit the selected option... however if scene location does not suit your selected option.. the vectors you get will not be suitable... even IF you use angle round reference surface....

Hope this helps

I am not trying to say it has anything to do with projection, at first I had two separate problems, one my imported

splines would project below the reference surface, and second the angle vectors were not normal to the surface.

I subdivided the splines and that took care of the projection problem. Now I am trying to figure out the angle control.

You are right I am missing some thing important but you getting all excited and capping me is no help. I will go

back and look at the pdf again

Hi There,

I am not 'excited, and 'capping' you' ??? .

My only concern is that if you say something is ommitted.. from MY ebook....it is in fact omitted.... I do believe I have some right of reply....

AND to ensure info in respect of CNC_toolkit in this thread is correct....

Some people take all caps to be the equivalent of yelling.

You have every right to set the record strait as far as omissions go, I admit I missed some things

in the manual and didn't understand the rest, and still don't, I just thought others might be having

the same problems as me and was trying to help. Maybe I am the only one who is having trouble.
