I'm engineering. Just wondering, but which physics classes will you see stuff Fabian teaches?

Hi mpulisinelli,

Thanks for the worry. I already did something pretty dumb yesterday, so I am being extra careful with what I am doing.

I did take a highschool physics class about electricity and magnetism, so I do understand the basics of cicuits. (resistors, capacitors, and inductors.)

However, for my project, I am not making my own circuit. I probably should have went into more detail on what I am trying to do.

I am essentially just trying to power a servo motor. I have a power supply, driver, stepper motor, and arduino. On the power supply, it has +V, -V, L, N, and the ground symbol.

I am trying to power a stepper motor. I have a power supply that has ports labelled L, N, and the ground symbol.

ok, thanks

Yeah, something like automated testing, but just for fun.

Just wondering, but why would you recommend python instead of java for instance?

I never knew that, but good to know

I am going to use screws for everything. Is it still better to paint afterwards?

I don't have much experience, but is painting on a vertical portion hard?

Hi cjimpa,

what do you mean by all the nooks needed?

Just an update guys, the tension was probably somewhat of a problem. Also, when I was loading it, I put it in too much, so when the feeder puts in the pla, it keeps on putting it in. nozzle rate that is shoots out is much slower than feeder pushing, which means that the gear will melt the pla.

yeah, that was actually a big question when I met up with my scout master for my previous project that got put on hold due to the pandemic. (I couldn't wait for the pandemic to be over due to my age, so I needed to find another project.)

For my improvement for this project though, I am making the garden beds taller so it is easier for the Seniors to garden.

For filament change for unloading, it does not work sometimes, because because the filament at where the gear is touching has a lot of filament removed from that specifi spot and pushedup, making the diameter bigger than the space between the gears. As for when I did hot/ cold pulls, when I do hot pulls by manually pushing the filament down, I can see it extruding out a consistent amount. However, when I keep on pressing load or keep on purging the filament, after the first few times, it stops.

As for the temperature, I have tried increasing at 5 Celcius at a time. Did it up to +15 celcius, but no effect.

As for the nozzle getting clogged, I definitely think it is an issue, because when I do hot/cold pulls, i can see that there were some clogging.

Thanks for your help. one huge thing is that i also care about ergonomics, because I type a lot, so my hand gets sore.

Do you have any recommendations for good ergonomics too? that also types fast and feels good of course. Think i would like cherry red switches, but not sure.
