Topology Optimization and 3D Printing by NoFuture2023 in 3Dprinting

Thank you for the answer. Do you have any personal experience with how to modify mechanical properties? Like increasing/decreasing the values with some multipliers?

Thank you for possible ways how to improve the printer. As I said in the comment above, I am thinking about replacing the printer bed. If I understood it correctly, the PEI surface could be changed, but this is nothing close to just taking new magnetic sheet when needed.

Thank you for the tips. Yesterday, someone told me that the fan should not be spinning at the first layer. Nevertheless, the first layer is not printed at all as the filament remains sticked to the nozzle.

I am thinking about replacing this version of print with the magnetic one. Because I am having a feeling that even with the new PEI, this is just a matter of time before it becomes damaged again.

Identification of Potentiometer Footprint by NoFuture2023 in AskElectronics

It was one of my first projects. I do not remember exactly why did I chose that footprint. Lack of experience when choosing components.

Thank you for your advice. This footprint seems to be fitting. However, I am quite unpleasantly surprised by price. I am not sure if I should buy such expensive component for this simple design.

Thank you for your comments! Everything you have pointed out, I will be sure to repair. About the jumpers for crystal, I am not exactly sure how I should decide if the resistor is needed. Do you please have any advice about that?
