      Your Z accelerations are very slow. M201 Z80 but the jerk is very high. M566 Z800. Try swapping those two values.

      Such a high jerk is making the firmware think the z axis is able to keep up to rapid changes in z position, but it can't actually. So the z movement is probably lagging behind where it thinks it is.

          How is the Z axis setup? What kind of speeds can we realistically expect from it?

            the Zaxis runs by 4 gearbox motors belt-driven. Expecting 100mm high-quality print speed

              Did swapping those values help?

                Yes it did little bit I also ran a quick print test and the results not really promising. Looks like some vibration issues from the X&Y Im note sure if it’s my external driver or maybe my linear rail. 2D8E8A6C-B11F-458A-920B-A18DECB57192.jpeg 980EAAA2-9104-4FA3-812B-2DBFD261EC5E.jpeg 02A225C9-B0A1-498A-8A0C-6C43D596F17C.jpeg

                  your jerk on the X and Y is insanely high. Try reduce that to 1000.

                    Ok I will do that over the weekend do you have any resources regarding the T parameters for external driver I need to understand what each number represent and how it can affect. I’m using theses motors they are Nema 23 with integrated rotary encoder. I order today RS232 Cable so I can connect them to my pc and se if I can change so of the settings to match with my config.g FAB41018-5AE5-486D-A777-2C06BCCAFC18.jpeg 807FEEA7-F873-4A87-8927-3B3837D69D1A.jpeg . Thanks for all your help I really appreciate it

                      If you do not have the specs for those drivers try T2:2:10:10 for starters.

                        So I did some lots of tweaking and here some results for a first full print it’s ABS print speed 3600mm/min Zaxis at 600mm/min print size 40x40x40 simplify 3D gave 1:18 hr/min estimate print time and it took about 1:40 hr/min. Bedtemp set at 100C and extruded at 235C But the quality is awful.

                        Here’s my new motor settings.

                        Here’s a picture of the actual print.

                        1FC79C11-5292-40AB-9769-5D08AA07FC15.jpeg C1C7AA38-AACA-4DC9-853E-50643010BC50.jpeg 81B5C307-93AF-47C0-AAC4-6BE85FF12D24.jpeg 1C372A95-0AF7-4E4D-B37E-11FB0902623B.jpeg

                        Even with that low jerk settings the printer is shaking from the external driver. Printer weights about 270 Ib I don’t know if I need to go lower value on any of the settings or maybe the external driver not override Correct value from the config. G file or any other suggestions

                          @moe-adams9093 said in G29S1 not loading during print and G32 not leveling properly:

                          M201 X1000 Y1000 Z400 5000:5000 ; set accelerations (mm/s^2)

                          You're missing an E on the extruder values.

                          Can you send M98 P"config.g" and post any errors that come up?

                            3/17/2021, 2:10:30 PM	M98 P"config.g"
                            HTTP is enabled on port 80
                            FTP is disabled
                            TELNET is disabled
                            

                            this is before I changed it didn't give me any error.

                              I think it may have messed up your expected Z and E accelerations. With the E missing you could send M201 by itself to see what it reports as the current values.
