TL;DR: Does anyone have experiences with CC Chargebacks through their bank or mijnkaart.be? How did it go?

As most people, I frequently buy stuff online. When it's a large sum I prefer to pay through Credit Card because the transaction can be disputed afterwards if it turns out you got scammed. However, I've never used this feature in practice and I don't know how likely it is that you will get your money back. (I know for Paypal it's quite likely, they usually choose the buyer's side. But I can imagine that CC companies are a bit more strict)

What kind of evidence is expected? Where does the money come from? The (alleged) scammer's account? Or some kind of insurance of the CC company?

Reason I ask now: I want to buy something from a site that I know has legit sellers, but is also notorious for having scammers. The total amount will be somewhere between 1 and 4k, which is a steal for this item, but of course it's still a lot of money. Usually if it's too good to be true, it most likely is, so even though I want to give it a shot... I only want to do it if I'm 100% sure that I'll be able to get my money back if it turns out to be a scam (which is quite likely).

Any ideas?

Newbie here. I'm trying to get a proper gradient with my cheap 10W laser cutter. Initially I was trying to calibrate it by going in the low-and-slow corner (see bottom right grid). But when I noticed that between 35 and 38% power, there was no difference regardless of the speed, I tried switching to the opposite corner: much faster movement, but also higher power (top left corner). There's still no significant gradient between two power levels, but.... now there's a new problem: not all blocks are square?! What the hell is this?

Note that when doing just squares (cut mode) it does have a noticeable difference (see top right).

Anyone who could point this newbie in the right direction?

Thanks!
