Has anyone found a suitable 3-axis post processor for Fusion360 that's workable on the Dyna 4M controller? Doesn't have to be perfect, but close would be good.
I have acquired a Dyna DM1007 mill, and after a little work it's functioning fantastic - however manually entering code on the control is getting pretty tiring.
Has anyone tried, as an aside, doing a swap of the floppy drive on the control for one of those USB-to-floppy emulator drives?
For future reference - so far it appears that the Mach3Mill post is usable for standard milling operations; it seems to work fine on the Dyna 4M control and the basic M codes are all doing the right stuff. The only note so far I have is to force IJK for arcs if possible as the control seems fussy about the R address. I have not tried any canned cycles or rigid tapping yet.
The Fanuc post may also work - that one gives you the option to explicitly force IJK. I haven't had time yet but I will try it once I have thoroughly tested the Mach3Mill post for compatibility.

That G18 G3 three lines above has nothing to do with it ?
Some one else with an old control posted problems with Fusion's swoop-dive style approach moves. I'm assuming this is an old control based on the 'floppy drive' comment in the first post.
Swoop-dive is a really good way to describe it. At first that G18 was the one I first suspected because it had the -Z movement. But that line is where the cutter drops to make the first pass. the downward plunge happens at G17. I'm really new to CNC providing I'm stepping block by block correctly. Its the highlighted line each time I press cycle start correct? It makes sense cause it happens after the cutter makes it to x zero and moves over to the next pass.
Yes its an older floppy system, I converted mine to SDcard but its older.
The Dyna control doesn't like the G17/G18/G19 plane selection G codes is all I can tell you. Why I noticed it is because whenever the processor parses one of those codes the motion stops; the motion planner can't handle going from a movement in one plane, changing plane, then moving again, without halting at the plane change code. I first noticed this on lead ins/lead outs that Fusion was coding using a plane change. I think I changed a setting somewhere so it didn't use plane changes for that and it solved that issue.
No idea why it would have plunged unexpectedly but it's probably somewhere in that code. The machine doesn't make **** up, it just does exactly what the code tells it to.
I removed this line and the the G17 responded as expected. Going forward when I generate tool paths I make sure lead in and lead out are disabled and it will not use G18.Quote:
