So I found out that my print bed wasn’t 100% level (and to be pedantic - it might still be out a little). I’m fairly certain it is flat (checked with some straight edges). To measure level and straight, I created a 95mm x 95mm x 0.25mm square (https://tinkercad.com/things/2BNzH08eGtH) and printed it.
The picture with ‘arrows’ pointing left is the top left (where my problems were) was clearly fatter and had gaps. Each of the 5 prints (from left to right) are the result of various adjustments. The other is the bottom right.
1 - control / original
Note the infill not reaching the loops and the fat lines
2 - raise back left corner 1 full turn, front left & back right 1/2-3/4 turns
Very thin loops, and thick infill fully reaching loops
3 - raise Z axis 1/2-3/4 turns
Gaps again in where infill reaches loops
4 - lower Z axis 1/4 turn
Filled in well, but a bit thin
5 - raise Z axes 1/8 turn
Good enough for now (certainly much better than before).
So, the word you’re looking for, is “tram”. Bad habit that we’ve taught people to use “level” all these years, we should do our best to try and break it.
Hmm, I would have thought “square” was more correct - never heard of “tram” (other than as a passenger vehicle on rails), but then again, I’m a tinkerer, not an engineer or millwright…
I think this is a bit of a regional thing. I’ve been in shops that refer to it as “square” and you “tram” to square the machine. Which makes total since to me. And I’ve heard tram as an adjective like its being used here.
I like calibrate and its the terminology I typically use in supporting our printers at work. Its an easy access term that everyone gets and isn’t easily confused.
You “tram” to “calibrate” your print head to the bed.
“Tramming” isn’t a good fit either, since this isn’t a matter of making the tool perpendicular to the table. I would agree with @Alex_Wiebe . We’re making the bed square to the axes (which are hopefully square to each other). “Level” is definitely technically wrong, but everybody knows what is meant.
