Post Processor for CAMaster Stinger (WinCNC)

[Anonymous]

Hello,

Awhile back I got some help with a post processor for my Stinger. I've been using it for awhile.

I've notice lately or have finally discovered that the feed rates are not matching what I specified in HSMXpress.

Attached is the post processor I've been using and an example file that shows the issue. The file is supposed to cut at a feedrate of 10 then slow down to 5 for the final pass. I believe that the feedrate at the start is what ever the last feedrate was when specified in a line with x,y and z. The attached cgode specifies a feedrate of 5 in a line with x,y and z (G1 X-0.3599 Y1.2933 Z-0.1126 F5) for the final cut. Afterwards the feed at at 5 even for new programs.

Please help

I've attached a few more files. It appears that if the lead in feedrate and cutting feerates are the same for an operation then the feedrate will be specified in a line with Z only. It will not insert a feedrate into the x,y,z line when starting the cut. If a feed in x,y was specified as something different in a previous operation this value will be the feed of the next operation.

Could you please upload your part also(including the toolpathes)? It´s much easier with it to reproduce your issue.

I believe the attached part and post should show the issue.

In the file is trace of an arced circle then a trace of an arced ellipse (both requiring xy and z).

The circle has a cutting speed of 30 with all lead in/outs ramps at 20. These speed seem to register correct in the post.

The second part of the post is the ellipse with all feeds at 40. The ramp of 40 seems to register correct in the post however it doesn't register in  the first xyz line. The resulting feed will be 30 carried over from what was specified on a xyz line for the circle.

Quick follow up after testing this cut.

The feeds witnessed for the second cut (ellipse) are z=40, X&Y=30. As mentioned they should all be 40.

Please try this one and let me know if it is working as desired.

Thanks! That seems to fix the issue.

Perfect, thanks for your feedback!

I've been using this post for HSMXpress in SolidWorks. Will this same post work in Fusion 360?

Yes,
no problem.

I am running the generic WinCNC post processor.  Everything is running as one would expect except when I concatenate tool paths.  It terminates each run with a return to safe height and stops the spindle.  It then heads to the next run with a dead spindle and crashes.

We are using the CAMaster (WinCNC) post (10113_CAMaster_wincnc_m3x_171014.cps) that was tweaked on this thread

However, our machine has fixed spindle and is throwing an error because of the T command in the code. After we delete that line, the post works just fine. Is there anyone who can adjust the post to eliminate it so we do not have to delete the line for every file we use?

Attached is the post processor I've been using that shows the issue. An example is pasted below.

Thanks of your help.
