Re: Problems with WCS output

What I think is kind of fragile is this https://github.com/FreeCAD/FreeCAD/blob/master/src/Mod/Path/PathScripts/PathPost.py#L294 (and additional occurences below), I think with solution #1 this would belong into the postprocessor if needed. I concur. Will you take a stab at a post-processor that ha...

Re: Drilling operation will gouge if retract hight < start depth

I have issue with the way the drill operation works when _not_ pecking.Even when pecking on the first hole the tool will rapid into the workpiece with default values! Here is what freecad outputs while pecking G83 F4.166667 Q5.000000 R10.000000 X5.000000 Y5.000000 Z0.000000 note the R10 command, th...

Re: Problems with WCS output

What is the 'non-posted' gcode? Do you mean the internal Path commands of the job? If so, then I agree. Yes, I mean the internal Path commands. 1) the postprocessor has to detect the fixture switch and insert additional commands before it to get the tool to a safe location or 2) The upstream proces...

Re: Problems with WCS output

What is the status now?

If some consensus is reached what to do I would be willing to implement it, but I'm not even sure it is accepted there is a problem.

Re: Problems with WCS output

With my machine, the only really safe thing is to first stop the spindle, move Z to machine zero (with G53 G0 Z0 command, cannot be done in FreeCAD, even custom commands eat G53 prefix. G53 is a non-modal coordinate system, at least in linuxcnc, you can't switch to G53, it has to be prepended each ...

Re: Problems with WCS output

The WCS functionality hasn't gotten much testing love so it's likely there's a problem. I'm seeing a couple things right off the bat. Even though both G54 and G55 are selected, the output isn't being generated for G54. I think that is an error in the dialog window, it selects G54 automatically. If ...

Problems with WCS output

Regarding G0 move towards Zmax: This is a very bad behavior. It implies that the tool is touched well to the surface. There are always tolerances. The stock may be higher at another position than touching position. Of course, stock configuration should include this, but mistakes happen. Heading to ...

Re: Edit Job: tool modifications not sticking.

There are many such inconsistencies throughout FreeCAD for lots of historical reasons. Sometimes a zero is required before a decimal, and sometimes not. Plain old zeros work sometimes and sometimes they don't. FreeCAD has been built by hundreds of coders over many years. 2. Document the details and...

If anyone can explain how I can get that shape into a form where 0,0,0 is on top or above the diamond top face , that would be very kind.
Either you move the object, or you move the model in the path operation (in the property pane, look for placement).
