Adxl345 on SB2209 board. Belt tension not officially measured - simply by feel. Measurement tool has been ordered.

Since it’s a DoomCube mod, there is no exhaust.

thanks 🙂
since u are US based, i would highly recommend u to get the pf makes tension tool https://github.com/Diyshift/3D-Printer/tree/main/GT2 Belt Tension Meter

#

by feel is not a great measurement and usually way off

I have a gauge to be delivered tomorrow!

in the mean time, loosen both belts by a 1/4 turn

Hello again! Just measured belt tension with the Biqu tensioner. According to their spreadsheet, both belts are measuring 10.94(N)

Small update. I toned down the accels significantly and it’s printing nicely. I am currently cranking out shop infrastructure for my little home shop on it so I haven’t changed the umbilical. I plan on getting my SW up and running this week to take some of the load and I will change the umbilical then

What is your belt tension at?

#

I see by feel

high folio Mar 11, 2025, 1:36 AM

#

No, I got a gauge. 10.94(N)

compact tundra Mar 11, 2025, 1:37 AM

What is that in hz

high folio Mar 11, 2025, 1:38 AM

1.65hz

compact tundra Mar 11, 2025, 1:38 AM

#

That does not make sense

high folio Mar 11, 2025, 1:39 AM

#

Figured it wouldn’t. I used the biqu gauge and their spreadsheet

#

I’ll do some digging tomorrow, re-measure and see about getting you a Hz measurement

compact tundra Mar 11, 2025, 1:40 AM

The spreadsheet says 10.94 n?

high folio Mar 11, 2025, 1:41 AM

Sure

#

high folio Mar 11, 2025, 2:27 AM

#

So I just gave a decibel gauge a try, and when I flick the belt with the tool head at 150x150y, it peaks around 71hz

compact tundra Mar 11, 2025, 2:29 AM

#

Let’s loosen those belts by a 1/2 turn each

high folio Mar 11, 2025, 2:31 AM

compact tundra Mar 11, 2025, 2:35 AM

#

I think we are going to have to manually walk it in

#

can you rerun belts

#

The gamma peaks are the ones that make me think the belts are to tight

high folio Mar 11, 2025, 2:40 AM

#

Wow too tight? They feel super floppy. I can rerun belts, luckily I have some spares. Will not be tonight though

compact tundra Mar 11, 2025, 2:40 AM

#

This is what is hard to convey. Belts at proper tension may feel floppy.

#

this is why by feel is not great

#

I am not sure if we are at proper tension or not, but I would like to see a change in the belts graph

high folio Mar 11, 2025, 2:42 AM

#

Interesting…. Yeah, I have a run of belt I can rebelt the printer with and start fresh

compact tundra Mar 11, 2025, 2:42 AM

there is no need to redo the belts

high folio Mar 11, 2025, 2:42 AM

What hertz are we looking for?

compact tundra Mar 11, 2025, 2:42 AM

#

110hz over 150mm

#

but that is unreliable also

#

everyone plucks different

#

I trust the pf makes tension tool because it can be calibrated.

#

this is an issue with the biqu and other meters like it. There is no way to calibrate it

high folio Mar 11, 2025, 2:43 AM

Ahhh I see. Might have to go ahead and get that PF makes tool

I read your ask wrong. Here is the updated belt graph after loosing 😕

compact tundra Mar 11, 2025, 4:41 AM

#

I would loosen the belts (not undue them) and start the tension over

high folio Mar 11, 2025, 10:14 PM

#

Significant improvement. Turns out two of my Z-joints were super loose. The gantry actually shifted side by side after I loosened the belts.

#

Improvements here too

Check your tap magnets

high folio Mar 12, 2025, 8:03 PM

#

I am using the dual magnet set up, and was considering going back to the magnets and screws.

compact tundra Mar 12, 2025, 8:27 PM

#

I mean make sure that the magnets are connecting flush with each other.
that z compoent in x-axis means that your toolhead is wobbling left and right

#

generally this is the tap magnets or tap linear rail

#

it could also be something else wobbling in your toolhead

high folio Mar 20, 2025, 12:30 AM
