What's causing this pattern on my first layer? (sh.itjust.works)

I'm printing with PLA on a "PEO" print bed (really a textured PEI), on my heavily modified ender 3, and there's a pattern on the bottom of my first layer that I'm trying to get rid of. The top of the first layer looks fine, and changing the z offset in either direction doesn't help. I've also tried slowing down the print speed because I thought the extruder might be skipping, but I'm still seeing it at 10mm/s. Any idea what could be causing it, and how to get rid of it?

Edit: the first layer went down from the bottom left to the top right, but the pattern I'm seeing is perpendicular to the extruder path

Depending on how the contract was written, running a clamav scan periodically may have been sufficient.

If I misunderstood your post, it wasn't intentional. Would you mind elaborating?

Either way there are a lot more contexts where one can use slut and not be shitty.

True, but I don't think that's the case here.

There's no "punching down", unlike with the antiquated 'R' word...

Women can't be "punched down" on? News to me...

Since this lawsuit only represents Texas, does it make it easier for people in other states to sue them for the same thing?

If that happens, they just fall back to the first option of waiting for their provider to set up the IPMI.

Not their supply chain, everyone else's.

They are fundamentally different types of vehicles. But putting that aside, if you want to compare the largest payload that each vehicle can transport you wouldn't just use the pickup truck's GVWR, you would also include it's towing capacity. There's a reason 90% of the time people use a pickup to haul something, they're towing.

This is why we can directly compare the two vehicles payload capacity.

No, comparing a zeppelin with a pickup will never be a direct comparison.

You're comparing a pickup truck to a zeppelin, there's no way to make that apples to apples. If someone needs to move something big with a truck they're probably going to tow it, not try to load it into the bed.
