        So it was sticking but not extruding because it was too close? Try changing the offset to say -0.1?

          Sorry been having net issues i'll adjust it 0.01 increments see if it works better.
          It was extruding and really sticking but as it did the next pass it was squishing too hard almost transparent and curling up at the outer edges indented in the middle as it cooled

          Thanks

            Hi NexxCat,

            Can I ask is Z hop enabled in the bed level test file you kindly sliced for me ?
            Or is that controlled via config.g ? ...so print files call M207: Retraction if Z hop is set on M207 in config.g Z hop is invoked on all Retractions ?

            Thanks

              This makes it sound like the first layer printed fine, but when printing the second layer it was too close, ie it didn't move correctly/far enough in Z. This made me think either you Z jerk or acceleration is too high, or your steps per mm are wrong (which would explain a lot!). I haven’t found the standard Marlin config for the Anycubic Predator, but did find https://github.com/halofx/Marlin-2.0-Predator/blob/master/Marlin/Configuration.h

              Steps per mm on each axis are 80, for standard 1.8 degree motors. You haven’t changed yours for 0.9 degree, have you?

              I haven’t been through the Marlin config for acceleration and jerk settings, as on phone with tiny screen! But would be worth checking. Just remember Marlin specifies speeds in mm/sec, RRF in mm/min. If you have the Marlin configuration.h you’re running on your standard board, even better; please post it.

                Firmware retraction must be enabled in the slicer. That will replace any G1 E-# moves with a G10/G11 to retract and unretract. The config.g must then contain an M207 command to tell the firmware how much and how fast to unretract. Zhop can be added in the slicer and or firmware retraction command.

                If you don't have an M207 command in your config.g then nothing will happen when a G10/G11 is encountered in the gcode file.

                If you look at the gcode file itself you should be able to tell by looking for G10/G11.

                  Hi Ian,

                  No they are set to 80 ...this is a Gorrila board which as far as I know is chit-tu based ? so M500 is like M8500 and not sure all the commands for it are known and the board is locked down... again as far as I know.
                  I wish it was set wrong...NexxCat was kind enough to have sliced the test file for me and it's very close so just using that to adjust trigger height..
                  it's really close but the Z hop seems to be an issue.

                  Thanks

                    Hi Phaedrux,

                    So my M207 is :M207 S1.0 F10 R0.8 T15 Z0.0 yet it is still Z hopping which is why I asked the question.

                    Thanks

                      Then it would be baked into the sliced gcode.

                      It sounds like you're getting improved results now?

                        Hi Phaedrux,

                        I feel like I am yeah.... no single layer yet setting up retraction/unretract FR etc which look good now(nimble so not used one before)
                        Trigger height is now Z-0.064 ....from my point of view not sure what the point of the Smart Effector is tbph but causing 6 weeks of frustration as what it reports... well is misleading.
                        i'll keep tweaking settings ..see if it will finally print that 1st layer .

                        Below print is mesh enabled 2 passes 8 mm/sec I measure it at .2 mm with calipers layer height is .2 mm so not sure what to change now.
                        I've rechecked extruder calibration its on the money.

                          My apologies for not replying sooner. I use firmware retraction and I believe that level_test.gcode I sent may well have an M207 at the top. You can delete that line manually and that should fix it. Sorry about that!

                            It's not a problem more me trying to understand and set my retract/unretract now more of the print is sticking I can finally set it for the nimble.
                            And understand the Z hop.

                            Thanks

                                  So..they discovered a Intermediate-mass black hole or planets aligned and I got not just a 1st layer but a completed print.
                                  Big thanks to all for your help in my quest to get a print.

                                    Is it a Tri-Gorilla? From Anycubic? If so, they run Marlin and you can load your own. Of course, figuring out exactly how the config was built... that takes some work.

                                        That's looking fantastic! Well done 😄

                                        Would have been nice if Anycubic bonded these glass beds on straight thought! I don;t know a single Predator where the bed pattern is square the the frame 😛

                                          No ..well done to you for slicing that file for me....Only issue is and the reason this board is being yanked out ...I have no idea why it's printed now no settings I have not tried before used today and I cant live with that sort of unreliability it has driven me nuts for 7 weeks the only reason it hasn't been torched is I wanted 1 print off of it.

                                          Yeah its like use a jig to stick them down how hard is it it has a cross hair!

                                            It seems a shame to swap the board out, but I do understand that after fighting with it for so long, you just want it to work. I wish I had the answers for you, but trying to diagnose a printer you don't have access to is difficult. All the same, if I can help in the future I'm certainly happy to 🙂
