      So I've set up firmware retraction with M207 S1.0 R0.1 F1000 Z0.2. so I should get 1mm of retraction and 1.1mm of un retraction...

      When I manually enter G10 / G11 commands, this is exactly what I get, but when these codes are in a gCode file, I get 2mm of retract and unretract... EVERY TIME... Anythoughts of what can bet happening??

        In the gcode there only should be the G10 and No lenght. Have you ensbled Firmware retraction in the slicer?

          Yes, Firmware retraction is enabled. Slicer is prusaSlicer 2.3

          A sample from the GCode file looks like this:

          G10 ; retract
          G1 X122.454 Y105.324
          G11 ; unretract

            Is pressure advance enabled?
            it can cause retractions if set high enough.

            Is firmware retraction enabled in the slicer?
            Is reprap flavour selected?

            If yes to both post the first 100 lines of so of a sliced file.

              How are you verifying that you're getting 2mm?

                On the DWC I can see the Drive amounts reducing by 2mm and then going back up 2mm on unretract.
                Note: this is on a mixing head so I have 4 extruder drives. I'm noticing this on the drives that are not active in the current layer/object.

                  This is on a mixing nozzle with 4 drives (Crane Quad)

                  Yes pressure advance is enabled:
                  M572 D0:1:2:3 S0.22:0.22:0.22:0.22

                  firmware retraction is enabled in the slicer

                  But... I did not have RepRapFirmware as the G-Code flavor. could that be the cause??

                    I did seem to be getting correct gCode:

                            So... This is interesting..

                            I have no config-override.g file in my /sys directory but after I sent an M502 command, G10/G11 worked as expected.....

                            Is this a hidden file?

                              IIRC, M3D used to do very strange things with their configuration files. Basically they used to break each section into a separate macro and then call each of those macros from within the config.g file. Is that how yours is set up? If so, it's likely that the changes you make to config.g could be overridden by later macros. I might be best if you post you config.g file and the full code of any macros that are referenced in that file.

                                it was for the 2.0 config, but for the 3.0 update I put everything in the one file. It loads with no errors, but I suspect maybe there was some override file hidden somewhere that had a different M207 command hidden in it??

                                  So, it all seems to be working now... not quite sure what happened, but...

                                  Thanks everyone who looked at this and scratched their heads...

                                    @nanoplane said in firmware retraction doubling:

                                    M98 PPrint_Start.g

                                    Should be quoted

                                      Thank you.

                                      One more question. does the M207 command need to be sent after the tools are all created?..

                                      I'm still getting the issue that the retract gets reset to 2mm whenever I start a new print from the "initial" state.

                                      my custom gCode for PrusaSlicer at start creates the per color tools and after they start being used M207 command returns 2mm for retract amount even though I'm setting it in the config file to 0.5mm

                                        Please share your full config.g you slicer start gcode and any macros you call in it.
                                        Also the results of M122 and M98 P"config.g" please.

                                            Also at the end of a print, custom gCode is:

                                            ; remove the extra tools so we restore back to standard
