Thanks for the suggestion. I think you are right: I tried to modify the .def.json file, enabling the prime_blob parameters without success. I will now explore the generated Gcode to discover where and how the prime blob is created.

Thank you for the suggestion. I modified the "overrides" element of creality_ender5plus.def.json adding : "prime_blob_enable": { "enabled": true, "default_value": true }, "extruder_prime_pos_x": { "enabled": true, "default_value": 30 }, "extruder_prime_pos_y": { "enabled": true, "default_value": 30 } but with only a partial success: now "prime_blob_enable" is visible in settings and can be enabled or disabled, but both the position elements X and Y have no effect: they can be checked in the Visibility setting panel, but are never shown in the actual setting. Moreover, the default values are ignored.

Hi, I am a novice in using Cura, and I've installed Cura 4.4. and jusr now 4.5 on Windows 10 64bit machine. My 3D printer is a Creality Ender 5 plus model, having a quite large hot bed, 350x350 mm. I encontered from the beginning serious adhesion problems to the hot bed unitil I got a PEI sheet 300x300 mm (the bigger I found). This drastically improved the quality of the printing jobs, solving the adhesion issue. But there is a new problem now: the Prime Blob that is printed at the begin of each job is printed outside of the PEI sheet area, and the nozzle height in this position is of course to big, because I tuned it taking into account the PEI sheet thickness. I tried both these: Clearing the "Enabled Prime Blob" option Changing the Prime Blob position with the "Extrude Prime X position" and "Extrude Prime Y position" options But I can't modify any of these options and a "this setting has been hidden ... message is trying to explain me the reason without actually explaining anything. Can anyone please explain me why these options are hidden with a preset fixed value and how to make them available ? Thanks a lot. Luca
