Seeking Post for UCCNC software for 4 axis Stepcraft 2/840 machine

Anonymous — Mon, 16 Nov 2015 18:43:26 GMT

Hi guys,

I've been running the UCCNC software on my stepcraft without an issue, using a basic Vetric cut product, that has a mach2/3 mm arcs post processor.

I tried to use fusion 360 and the mach3 post processor with the UCCNC but for some reason got a bunch of errors talking about unknown arcs errors.

Other users of this combo of stepcraft on the UCCNC have said the same thing.

the software is from here, Stepcraft has the UC100 motion controller

Straight form the Autodesk CAM Post development team.

They have more posts than are supplied with the software for multiple reasons. One for example being that they have an idea on how it should be but never get feedback on them.

In fact I did this one the same day and tested it as far as possible on the UCCNC simulator.
But Laurens is right, the more feedback we get the better.

Hi guys,

I tested a post for a Bore operation, and I get an arc error at line 54, which is where the R value drops to 0.02

We tried turning off helical moves, and upping minimum radius and minimum chord values to 0.2, but this did not change the value in line 54, and the error persisted. PLease try it with your UCCNC simulator.

We have absolutely pulled this out of thin air, I changed the tolerance in the passes menu, from .01, to .02, and the arc errors went away. any ideas why?

Do you get the same error in your simulator with the pass tolerance at 0.01

Hello guys,

Can you please tell me, is the 4th axis ( rotational called a axis in the software ) enabled in this post processor ?

On my machine - we installed the 4th axis, so that the rotation axis, is parallel to the the Y axis, and located inside the max y axis travel values, and about half way along the x axis.

njfinch81 there are some G codes that the uccnc will not like, you need to make sure they are not in you Gcode ask on the uccnc forum or cnczone.

support needs this info

I figured it out

I opened up and edited the generic UCCNC post that fusion admin provided me

I changed this line which was initially set to false, to true,

if (false) - changed to (true )
var aAxis = createAxis({coordinate:0, table:true, axis:[-1, 0, 0], cyclic:true, preference:1}

then figured out that the axis command, was enabling the orientation of the rotation axis as in line with x, y, or z, + or -1 are rotation direction.

Don't know about the other bits, however the G code output now for multi indexed faces works !!!!!!!!!!!! yipeeeee
