I’ll give you that. He’s an advanced level of stupid that I’m surprised he has any amount of influence at all…

I don’t think there’s ever been smart ones… They constantly have to scapegoat someone lest the rabble finds out they’re just pilfering the country and everything is collapsing.

If the service isn’t starting due to a changed port then one of two things are happening:

1. Something else is using that port and its throwing an error
2. There’s a configuration issue (typo, comment, or duplicate setting) that is preventing the server from starting

Do you have any logs from the server that might help with determining which of these two it is?

Also are you trying to access the service on your local network or via something like your mobile data or a VPN? Because if it’s the latter you probably need to configure your router to allow external traffic (which can be a security risk).

Did you open the port on your laptop’s firewall to allow the traffic to the new port?

What issues are you having that would require changing the port you use would fix it?

Believe me it’s better to be ignorant about this…

It’s because your nozzle is ever so slightly too low when you’re printing. I’d adjust your Z offset by one click upwards.

Reprint the cube, and see if that resolved it. If not adjust upwards by another click.

If after a handful of times you can’t get a decent ironing pass, I’d take a look at your extrusion multiplier. Drop it down by 0.01 and recalibrate and retry doing the above ironing calibration sequence again.
