Then I recommend Prusa Slicer.

This is likely a slicer issue.

What slicer?

Randomize Z seam

There is never a situation where this is a good setting to have on.

_ I’m not using … “retract on layer change”_

There’s your problem.

No matter what printer you get,

I recommend avoiding any printer designed to move the bed in the Y-Axis.

It’s an old design prior to CoreXY and it isn’t needed anymore, and has a lot of cons compared with no pros.

government regulation to force companies to begin using a modular system

Yeah, that’s fair. But the issue is also similar to cell phones.

Each battery is unique because it needs to fit the unique layout of the vehicle. Not to mention the battery tech is moving so fast, that the chemistry of the battery itself is changing every few years.

I suspect China’s approach to a vehicle where you hot-swap the batteries instead of charging will be the way it goes. Someone will do it, it will be most $$$ efficient and therefore profitable, and then it will force them all to adopt the same approach.

The replacing the battery is simply a supply issue.

There is such a demand and so little supply, that if you want to buy just a battery (and not the entire car) you are out of luck. They’ll put that battery in a new car and sell it before selling it to you as a replacement.

But that’s short term. There are a huge number of battery plants already breaking ground and coming online.

In 2 years or so, the price to replace the battery will be a HELL of a lot lower, and the issue you linked above will be long gone.

I can now finally solder things easier.

Drink my coffee while gaming.

Use Push to Talk a lot more while gaming.

Hold the ladder, brace, and hold a nail and hammer all at the same time.

Stuff with motors are, like air con and refrigerators. Those are better left on AC.

No. Trend is they are all showing up with frequency drives. Of which those inverters are rectifying to DC before making their own AC.
Efficiency gains are massive of a frequency drive , hence why they are doing it.
Would be even better if they could drop the first rectifying circuit and just use the inverter portion only.

You lose very little by rectifying AC

You lose a lot actually in all the small cheap rectifiers that are in every device in the house.

Where a single purpose designed FET rectifier that is built for efficiency at the breaker would be drastically better.

You wouldn’t have to.

Every device instead of having an expensive PD communication device in it, would have an even cheaper PWM DC Step-down.

No communication needed.

Each device would just draw what it needs to.

_ It wants 3.3V, or 5V, or 12V, or 48V, or 18.7V,

Exactly

That’s why if you had a 110VDC supply at the wall, you do a simple PWM step-down to the required voltage in every device.

LOADS cheaper/efficient than any USB-C PD circuit…

Saves on transformers, saves on dozens of USB PD wall outlets, saves on communication needed to communicate the PD required between each device and every USB PD wall outlet.

Much cheaper. More efficient.

If only the wall was 100VDC instead of AC

No, AC requires large heavy transformers and then rectifying.

DC dropping down to a lower DC is way easier and more efficient.

Well, I mean if you don’t understand power electronics I don’t see how you can make that statement.

What?

Most vaccums are brushless, where they are already converting the AC to DC internally. Your vacuums would be cheaper.

Where would I recharge batteries for my lawn care equipment?

again what? The same way? Your charger is converting AC to DC. You could skip that step.

All of these appliances would work better/cheaper with a 110VDC@15A source.

powerful DC-DC

No, are you not aware how these work?

A step down DC-DC is nothing compared to a transformer rectifier or PD electronics with communication with a USB-C.

again, simpler and cheaper electronics for everything

PWM DC to DC dropping voltage to what you need is easy/cheep.

So instead of a big transformer + rectifier that each device has now, it would be a much smaller/cheaper step down at like 99.8% efficiency

Yeah, but frequency drives/inverters were still pretty pricy things back then to for high powered motors for compressors/blowers/etc.

But the cost and efficiency of those things have dropped SIGNIFICANTLY in the past decade…

_ I don’t think USB C PD could handle a hairdryer though_

Of course it wouldn’t. The idea would be get rid of USB-C and PD completely.

You’d have 110VDC@15A available for your hairdryer. Heating coils don’t care if it’s AC or DC, and the blower fan would be a brushless fan.

You’re compressors for AC or fridge would be freq drives, which are cheaper because they could drop the rectifier circuit, and highly efficient.

The only real concern about having DC in the home as standard is the safety aspect of DC doesn’t let go if you get shocked.

But that is already being worked on in general as many homes have high-voltage DC circuits from solar panels.
