I’m not entirely clear on the problem, but yes - the circuit as drawn makes the microcontroller pin start high, then fall after some time. Do you need the microcontroller pin to have a different voltage than the transistor base (I assume when you said gate you mean base…gates are for FETs), or is this good enough?

Would a circuit like this power-on reset circuit work for your application?

There was a bit of a learning curve but after a few days I found it works very well for my needs.

I’m curious what a parametric offset would be. If it is what I think it is, I’ve accomplished that with some construction geometry. Add a construction geometry line constrained appropriately (e.g. perpendicular to some other line, particular length, etc) and then use its other end to attach and constrain the offset line.

LFP cells have excellent cycle life anyway (2000+ cycles); is it worth worrying about staying at 95%?

Those are resin prints, not FDM prints. The print technology (FDM vs resin) is the bigger factor than the actual plastic used (PLA vs others).

And that level of detail is impossible with FDM regardless of the plastic used.

“ERRF” was terrible to say out loud, and as hell weaver said above, even many people interested in 3d printing won’t know what RepRap is.

Are the test models ones that come with the printer, or models you’ve found online? If they’re from online, does the printer ship with any you could try? Something sliced by the manufacturer is most likely to work. If those fail, I’d contact customer support.

I have no experience with resin, but is the resin coin stuck to the screen or the build plate? Are you angling the chess piece or trying to print it straight / vertical? My understanding is that resin prints need to be carefully aligned so they’ll peel of the screen, and big flat surfaces like the bottom of a chess piece won’t.

It’s because of the “lift to drag ratio”. Airplanes in level flight at ordinary speeds generate about 15x as much lift as drag meaning if the engine spends 1 unit of work moving the plan forward, the wings give 15 units of work* upwards. So flying level needs about 1/15th the engine power of going straight up. (I’m using “work” very sloppily here, not in a precise physics sense.)

You can see this in sailboats too, which can travel faster than the wind when they’re sailing at an angle to the wind. Efficient boats travel faster when they’re going almost perpendicular to the wind, not straight downwind! This is because the “lift” of the sail pulling the boat forward even more strongly than the push of the wind in the downwind direction.

While I can’t give an intuitive explanation for why this is, there’s a very easy demonstration that it’s true: kites. If a kite had a lift-to-drag ratio of 1, then it would fly at 45° up. It would fly 50 meters downwind of you when it’s 50 meters up. But any decent kite can fly at a much steeper angle than that; sometimes they look like they’re right over your head! That’s because with a lift to drag ratio of e.g. 10, the 1 unit of drag gives 10 units of lift; if it’s 10 meters downwind it will be 100 meters high.

Check out paragraph 81 of the indictment. One of his co-conspirators was having a discussion with a lawyer; the lawyer said staying in office past January 20 would trigger “riots in every major city in the United States, and the co-conspirator replied, “Well, [lawyer], that’s why there’s an Insurrection Act”.

Are you using leaded or lead-free solder? If it’s lead-free, it has to be hotter and you may also find extra flux helps.
