Since Tormach made it Public they supported Right ot Repair and Subsequent call out video they Released most all their schematics and firmware files. Still waiting on the VFD files, VFD Unlock Codes, Pic Chip Config Bit Settings.

Their Github is at github.com/tormach/Repair-Information

I did update my Lathe Control Board's PIC16F1947 Firmware


Config Bits Read Form My PIC16F1947:



I also updated my PCNC 1100 Series II Boards PIC16F872 to a Series III Seems to be Working fine.

This is great!!  I wonder if they will release the code, used to generate the lathe ATC hex files?

Iron-Man, I am not sure about the source code I don't expect they would unless required by the Linux CNC license. I know they released the firmware for the Lathe Control Board and the Schematics along with the Schematics for the Lathe Turret Board.

I would agree with Contract_Pilot on this.
I see no indication the schematics are open sourced/hardware. they carry no disclaimer of license and state they are for repair purposes and so the firmware being supplied in OCO (object code only) would tend to indicate no intent to share source. But this is only my opinion and would be happy to be proven wrong.

I do hope they will release PP publicly on github though.

smgvbest, There is enough to repair the source code is not required for repair or to even to support of right to repair just the compiled Binary and since it is a Pic Config Bits. Asking for the source code is a very tall ask.

I see that they have posted some of the pic config bits I provided them on the GitHub wish I had other boards/hips I could read and grab the others. 

When Asked By Rogge for help with obtaining the config bits because they may no longer have them., I did say yes, that I would be willing to pull the config bits for the other pic chips. Have Yet to hear back form them on this. Right now my chip programmers have been very busy with paying work anyways.

Contract_Pilot I am not asking for source just to be clear. I am stating why I do not believe we would see source for the firmware on the boards. But do have the hope Tormach would publically release PP on github.

I do have the PP2.0.5 Source from Tormach. Free for asking just $10 to cover expenses to make a disk and mail it.

A disassembler can be used to go from hex to assembly code.  Here is a partial listing using the PIC 16F83.inc file.  This was the closest I could find to the PIC 16F1947, which is a 8 bit device using 14 bit words I believe.  The circuit board could be designed in KiCad or Altium designer. I do not know how Tormach would feel about this.

@Iron-Man with disassemblers and decompilers some work some do not.
