RDR,
On my Mach4 Part3.txt just displays the Toolpath as straight line.
I keenly interested to know how it is showing correctly on your Mach4 and not mine.
Do you have any special Lua Script coding or settings?
Are you using a standard screen set?
Can you send me a copy of machine.ini and your Screen set please so I can get to the bottom of this problem.
Regards,
Mauri.

I use Rhino/madCAM 5 and Aspire 9, but have used others like BobCAD and DeskProto.

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

RDR,
For am moment there I was hoping for a Toolpath 4 axis visual solution with Mach4.
From what I have been told it is supposed to show 4 axis displays, but they have not been able to make the 4 Axis Toolpath display correctly in the Toolpath program part of Mach4.
None of my Cam programs can generate the G93 by themselves, however I have someone working on a solution that will convert the G94 G-Code to G93 G-Code accurately.
Thanks for you code.
Regards,
Mauri.

It shows 4th axis stuff sometimes but the toolpath is way off.

RDR,
Can you provide that CAM picture file so I can use it as a test for G93.
It can be in STL or any Rhino5 format.
Example .3dm - .igs - .iges - .obj - .stp - .step - .wrl - .wml etc.
I will then Use Rhino5/madCAM to produce the G94 G-code and use the test G93 programs to convert it.
Regards,
Mauri.

RDR,
Just to let you know BobCAD does support G93, I was using a Mach3 Post and it did not have G93, but other type Posts that work with Mach4 do.
How ever the 4 axis version of BobCAD I have does not support simultaneous axis machining, that is why I use madCAM.

Mauri.

RDM,
Here is a sample of the BodCAD G93 output.

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

RDR,
Thanks for the file,
I have also found that some systems use TCP (Tool Centerpoint Control)
It uses G43.4 to activate it (not available in Mach4).
It maintains the X/Y/Z F speed with A/B/C axis.
