Techno Titan CNC NC file running error

[albino.caporale]

I've been using Fusion 360 for a few years creating gcode files for a shopeoko cnc.  I recently joined a mekerspace that has a Techno Titan CNC.  I would like to continue using Fusion because I know it enough to do most of what I need.  However, I have been unable to get the Gcode generated by fusion to run on the Techno machine (basic 2d contour as a test).  I've tried the Titan post processor and when I attempt to run the file I get "Invalid M-code m37" and the file won't run.  I noticed that the gcode from Vetric that I've ran on the machine is .nc file while the Titan post processor uses the .tap extension.  I tried the generic techno post processor which uses the .nc extension, when trying to run that program i received "NC File running error invalid code g27".  I have no idea how to go about figuring this out.  Any help would be much appreciated.

I've attached thie files below.  Template is the file from Fusion I can't get to run, Pocket is one from Vetric, which works.  I saw in a previous post a working file may be helpful

You dont say which of the Techno posts it is. I am assuming the CNC Win controller based on the *.tap extension. I would guess you are not setting the tool offsets correctly or are missing some of the parameters for the M37 Call.

Thanks for your reply. Sorry if the following is confusing, I'm a bit out of my depth here. I tried posting the same operation (single tool path using one tool) from both the Techno post processors I was able to find.  The machine is a techno Titan, however it uses a pendant to control not a computer running Win CNC.  I'm not sure if the pendant could be running the Win CNC controller or that can only be run from a PC.  Both post processors gave different errors the .tap was invalid mcode m37, the .nc invalid code g27.  Looking at the files in a text editor both g27 and m37 appear to be in the same location, my guess it might be the same issue.

My (limited) understanding of tool offsets is that Fusion assigns the tool a # and offset # that corresponds to a tool # and offset measure stored in the controller.  I though maybe a tool offset wasn't stored in the controller, so I measured the tool according to the procedures outlined in the machine manual and tried re-running the program.  I still got the same error.  I haven't been able to find a way to disable the offset in Fusion.  Would it be possible to change the following code:  N17 M37 H1
N18 G00 X-3.44761 Y1.4753
N19 G43 Z1.075

to

N17 M37 H1
N18 G00 X-3.44761 Y1.4753
N19 G49 Z1.075

This idea is form this found in the Techno manual: "M37 turns on G43 mode, indicating that tool length offsets are active. Tool length offsets can be disabled using G49 and re-enabled with G43 without re-measuring"

Hello @albino.caporale 

Looking at the template.nc code, it appear to be a code generated for an Osai controler.

The techno website, never referenced Osai as a regular controler for these machines.

I generated code with the techno cnc titan series wincnc post for testing.

But the output is not similar to the content of the "Pocket 1.nc" file.

I suggest to test using the Fanuc post.

If it complain about the G28 code, you can modify a property to swith to G53.

I do not advise to change a G43 into a G49, that will be driving the spindle nose instead of the tip of the tool => Collision assured.

Regards.
