No idea, but I think I measured the paper wrong the first time, think it’s actually 0.12mm, so the wrong math was actually right, for an offset of -0.12. If I did the math right, the offset wouldn’t be -0.12, with the wrong paper size number. The offset would be -0.08 in that case.
Might need a new nozzle already though. Good idea, put one of the nozzles it came with on, and see if that works. Or the same kind that is.
I was printing something, took a piss, and when I stopped the print, it got the nozzle covered in some melted plastic.
It can’t even print the skirt. Do steel nozzles work better? Don’t really want to add anything else to my cart though.
I suspect 0.12 isn’t clone enough, so I’ll try -0.14. Doesn’t look exactly too close. But using -0.20 is probably too close, that’s touching a 0.12mm piece of paper. Not sure .2mm will be enough though, perhaps -0.16 or -0.18.
Guess I’ll try -0.16, and watch it, so that it doesn’t destroy a bunch of parts, and need replacements again already.
Or I could wait for my feeler gauges to come, there’s a 0.20mm one. Once I order it that is, tomorrow probably.
I’d reckon, setting your Z offset with paper is the most work method. If you set exactly to what you get, you’ll damage the printer, and have to replace parts. Doesn’t sound like a great method to me.
And I’d reckon I use metal objects on nozzle when it’s hot, I don’t mind scratching it, I have lots of those nozzles. If I don’t damage anything, maybe it’ll print the skirt right at least. The nozzle can be changed after that.
It’s not heating up as fast. So probably need to inspect the hotend. Is changing it with Cura even working? Maybe cause looks a little better. But still not right, now to try -0.20. If that doesn’t work either, I may need to change the offset on printer, or use the extensive Z offset processing option.
So maybe the paper method works, if the leveling of bed is better. First manually level it, use a digital level. Then use auto level, then Z offset. Make the corners match as close as possible to the middle, when manually leveling it.
Still ain’t sticking very well. Starts out sticking. Think it’s doing the same thing, no matter what I set Z offset to. So Cura is broken. Or my firmware is. Got to change back to -0.12 and enable the extensive option.
You are supposed to set the Z offset based on corners not middle? It’ll be slightly different for each corner. At least right vs left side.
If using the extensive option doesn’t do much, I’ll just wait for feeler gauges. And then do the corners. Paper can light on fire, so if the bed is hot, you might light it on fire. Waiting for it to cool down over and over again, is a real long time.
If you look at the GCode Viewer, in OctoPrint, that ain’t what it looks like. It can’t print an entire circle. Maybe the bed is messed up, from bad print. Guess the residue damaged it. The layer height, makes it so it’s setting it to only -0.02. I should use the layer height when using the feeling gauge. That is set printer to whatever layer height you use. Instead of 0.
I must have followed bad instructions for setting Z offset, or didn’t read it all. But that would explain why the offset is wrong, if you set it from 0. Luckily, I didn’t break it again, I don’t think.
No wonder using Cura is safer, you might not be able to damage printer as easily, if at all.
