  1. Your nozzle is way too far from the bed for the first layer. You should adjust the bed leveling screws to bring the nozzle closer to the bed, to the point where a piece of paper just barely fits between the nozzle and…

  2. As most answers here: "That depends on your preference and needs" If you prioritize bed adhesion you might want to compensate for an uneven bed surface/ level and maximize the layer height, which is around 60/75% of…

  3. After tightening the screws on the X-axis gantry and doing the bed leveling and test prints again it seems to have gotten better.

  4. Since nobody had any idea what cause the problem, I investigated for a full week. The problem is related to Fade Height and .... a warp bed , since I have ABL (Auto Bed Levelling) and Fade Height enable.

  5. This sounds like nothing but a bed leveling (distance from nozzle to bed) problem, though you may have introduced other problems disassembling the hotend.

  6. There are a few questions on this topic, so a more generic solution would be informative and will prevent multiple questions of others when their sensor has a slightly different location.

  7. I measured mine with a thread gauge and it says the pitch is 0.7 mm . So, as the stock adjustment wheels have 14 bumps around their circumference, turning by one of those is an adjustment of exactly 0.05 mm (assuming no…

  8. You are probably looking for something like this : Note this is for large beds (300 x 300 mm), so you would have to X, Y scale this in your slicer.

  10. PETG does this. PETG is like glue when soft this is why when you level the bed you have to add an additional 0.1 mm distance for PETG. PETG should not be as close as PLA, but futher away.

  11. Perhaps the culprit is a pull-up resistor on the board. Normally, endstops on 3D printers use the microcontroller's internal pullups. These have a resistance of around 50kΩ, which is far too high to be a problem.

  13. There are various designs which can be made to work at 100 °C. For example this solenoid probe uses a solenoid to lift a plunger during print, letting it drop during probing.

  18. The Z-offset is the distance between the nozzle and the triggerpoint, see e.g. this answer of question Automatic Bed Leveling (ABL) with a sensor (BLTouch, inductive, capacitive), how does it work? .

  19. From your images can be seen that: Your nozzle is too far from the bed (the lines are not touching), so you either need to level with a less thick paper or allow for more friction between the paper and the nozzle.
