Hi,

I don't know which pictures to post,but I have a question.

Build is V 2.4 with SB2209, cartographer, manta board etc.

Both diagrams are from different adxl modules. One (21:19) is from ADXL from SB2209, and the other (22:03) is from Cartographer adxl module. Both are ADXL345.

I mainly ask about this gamma parameter and how to adjust it? Secondly which module should be more accurate (Carto is closer to nozzle, SB2209 is closer to rail)?

Thank You for answers ๐Ÿ™‚

Reth also has a great video regarding how to read and understand the graph https://youtu.be/-fKI9xY3LLI?si=_L0l1wmbYIEcsZfv

Question: how do you know when to loosen and when to tighten the belts?

Short answer: it depends.
Long answer: please watch video.

Yeah, I saw that video, but still wanted a answer from proffesionals ๐Ÿ˜„

#

ahh, so this disables the movement right/left. Ok ๐Ÿ™‚

#

still "gamma" parameter appears after change

#

and there is omega also XD

#

Multiple spikes are labeled with alpha, beta, etc.

#

Toolhead board is better for general troubleshooting

upbeat fable
#

why there is more than 2 parameters (alpha and beta) which are in most videos and pictures?

bright swan
#

U cant just adjust one spike

upbeat fable
#

ok, so more than one spike means more parameters

bright swan
#

Sometimes its just 2, sometimes 4

#

Nothing bad

#

U also have to be very careful

#

This graph only shows relative tension

#

And NOT absolute tension

upbeat fable
#

And which adxl is better for belt tension and which for vibrations? I would assume SB2209 for belts and Carto for vibrations?

#

Okay, thank You ๐Ÿ˜„ Case closed ๐Ÿ™‚

I understand the labels alpha gamma etc are used instead of 1 2 3 for the peaks

Time to look into the CAD๐Ÿ˜‰

Check CAD and compare with yours.

Screw head vs nut

#

yeah, I know

bright swan
#

Thats why I Said check the CAD

bright swan
# upbeat fable yeah, I know

In your current setup the screw can fall out. I think u can Imagine thats not good and can cause damage to your printer

#

If the screw head is on top, like in the cad, its impossible for it to fall
