Hi all with Ender 3 Pro, I'm getting frustrated with my printer and it's been a month already that I can't use it due to problems I can't find how to troubleshoot. I changed my motherboard from V4.2.2 to V4.2.7 with bltouch from antclabs. I believe I followed all the instructions including upgrading the firmware to "Ender-3_Pro_HW4.2.7_SW2.0.9.03_SpritExt_H300". And on my Creality Slicer, I added "G29; Auto bed leveling" on Tools>Manage Printer>Machine G-Code>Start Code Describe. My Printer Info is Ender-3 Pro Software 2.0.9.03 Hardware 4.2.7 2.0.8.2 2022-05-10 www.creality.com Extruders:1 Baudrate: 115200 Bilinear Leveling My steps once I turn my printer on were: First I do the Configuration > Advance Settings > Temperature > PID Autotune E1: 200 then click then, Configuration > Advance Settings > Temperature > PID Autotune Bed : 60 then click My last PID I got after Autotune are PID-P E1: +041.3 PID-I E1: +004.37 PID-D E1: +097.6 After these, I go to Motion > Auto Home > Level Bed And then Probe Z Offset to whatever distance I see fit (one time it's +3.700, the other time it was +4.300, it depends of how high the extruder was after auto home. Then I set the Temperature by preheating the PLA. At times the printing is fine on the first level up to the 3rd to 4th level, but then I noticed that the extruder is dragging on my print and the problem occurs. I think my Z axis is not going up properly and I can't figure out the solution to this. At times I am getting the "Heating Failed: E1 PRINTER HALTED Please Reset" notice. But once I get that I Autotune my PID again and it's okay. Do I miss something on the steps I was doing? I keep on searching on the web with regards to this kind of problem but I can't find any. Seems I'm the only one experiencing this. Hope I can find a help on this Community. Thank you in advance. and Happy New Year.
