hi there i've found a solution. the problem is based in the Marlin firmware look for the DEFAULT_AXIS_STEPS_PER_UNIT lines in configuration.h and modfie them as below (hard setting to 80/80/80/96 and not using the calcualtion from marlin 1.1.9 below is what i've done. after that my timing for the try prints was good again, i will go on testing. you can follow the discussion in https://github.com/MarlinFirmware/Marlin/issues/15466 BR Martin /** * Default Axis Steps Per Unit (steps/mm) * Override with M92 * X, Y, Z, E0 [, E1[, E2[, E3[, E4]]]] */ #define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 80, 98 } // DaHai: This is no longer used in Marlin 1.1.9 - it is now calculated below (But extruder steps must be defined) /** * Default Axis Steps Per Unit (steps/mm) * Override with M92 * X, Y, Z, E0 [, E1[, E2[, E3[, E4]]]] */ // variables to calculate steps #define XYZ_FULL_STEPS_PER_ROTATION 200 // DaHai: These are the setting for the stock Stepper Motors, pulleys and Belts on the AnyCubic Kossel #define XYZ_MICROSTEPS 16 #define XYZ_BELT_PITCH 2 #define XYZ_PULLEY_TEETH 20 // delta speeds must be the same on xyz //#define DEFAULT_XYZ_STEPS_PER_UNIT ((XYZ_FULL_STEPS_PER_ROTATION) * (XYZ_MICROSTEPS) / double(XYZ_BELT_PITCH) / double(XYZ_PULLEY_TEETH)) #define DEFAULT_XYZ_STEPS_PER_UNIT (80) //#define DEFAULT_AXIS_STEPS_PER_UNIT { DEFAULT_XYZ_STEPS_PER_UNIT, DEFAULT_XYZ_STEPS_PER_UNIT, DEFAULT_XYZ_STEPS_PER_UNIT, 98.0 } // (extruder steps defined) default steps per unit for Kossel (GT2, 20 tooth)

Hello, I have the anycubic Kossel linear plus. With one run I update to cura 4.x and Marlin 1.1.9. problem is with all 4er Version of cura. Since than my prints take 1,5 upto more than twice the time estimate in cura. I've already tried different settings in marlin and also couple of stuff with acceleration and jerks in both parts (cura and Marlin). Does anybody had an idea if there may be some hidden setting that's lead to a mismatch with delta-printers? *Baggging* for help Martin
