4th axis setup in mach3
« on: February 03, 2015, 05:50:07 PM »
I am setting a 4th axis and for the most part i have it working just fine but for some reason the toolpath display is wrong my a axis wraps around the y axis  i am trying to have it display like a cylinder but for some reason it is displayed like a plate  it seems to cut properly ( alltho so far all i have cut is air ). I have searched for the solution and could not find it if its there please point me in the right direction thanks in advance  ;D

Look IN Genconfig /toolpath and see IF you have it set for X/A.

under general config I cannot find that setting I have active plane of movement then as x-y selected although if I go to config then toolpath under rotations I have y axis selected a check mark in a rotations enabled and a check mark and use diameter for feedrate

I think you also have to set the Rotation Radius in the Settings Tab.  It's been over a year since I used it, so there may be another setting I also used.

In Config>Toolpath, make sure A-Rotations Enabled is selected also.

it is selected and the picture that you posted John is exactly what I'm trying to accomplish but for some reason it isn't that I will try to take a picture of what I see so that you can see what I'm talking about

On the "Settings" tab right upper corner input the "Rotational Radius" A as the radius of your part.

In your ToolPath Config. screen, if your A is replacing Y in the GCode, then the Axis of Rotation will be "X-Axis"

Here is a clip from the CNCWrapper help file.
