400mm 3.1 mesh

definitely not great.... but I haven't even tensioned the belts correctly yet. Just starting the thread now because I know I'll need it.

for the record this has a weird printhead that limits some area of the mesh which might lead me to some annoying troubleshooting.

oof

LemcottOP•12/15/23, 4:24 AM

okay, thinking about this some more before doing anything major.

I thiiink this is mostly gantry related?

LemcottOP•12/15/23, 4:44 AM

well damn

LemcottOP•12/15/23, 10:39 PM

man I can not get the belts to tension without ripping them out of the EVA blocks.

Oskait•12/15/23, 11:28 PM

Something is very wrong. Your mesh goes up to 3.4mm!!
If it is gantry related your gantry is crooked af
I guess you tried loosening the rail and tightening the screws from one side?
what probe do you use? did you run z-tilt before the mesh?

LemcottOP•12/16/23, 1:17 AM

pinda, z-tilt usually takes 3-4 tries.

gantry is definitely crooked on the Y, but that is because I can't get tension on both belts equally without them slipping out of the tension block

LemcottOP•12/17/23, 1:15 PM

so I just set my rotation distance from 8 to 2

LemcottOP•12/17/23, 1:15 PM

this should help

LemcottOP•12/17/23, 1:17 PM

but I won't really be able to today (not enough spare time)

Also I still can't get my belts to tension without them ripping out of the eva blocks

LemcottOP•12/17/23, 3:49 PM

found a bit of spare time

LemcottOP•12/17/23, 3:50 PM

ztilt only takes one retry now!

LemcottOP•12/17/23, 3:54 PM

LemcottOP•12/17/23, 3:54 PM

well that is one hell of an improvement

LemcottOP•12/17/23, 3:56 PM

LemcottOP•12/17/23, 3:57 PM

a 2.165peak to peak difference (and that includes that one weird outlier in the back left) thats... that's pretty good?

LemcottOP•12/17/23, 3:57 PM

it is definitely still gantry related

LemcottOP•12/17/23, 3:57 PM

there might be an obvious reason why I'm missing, but I do have some other theories I need to try out

LemcottOP•12/17/23, 4:11 PM

LemcottOP•12/17/23, 4:11 PM

Well that is something obvious

LemcottOP•12/17/23, 4:11 PM

That magnet should be here soon

LemcottOP•12/17/23, 4:22 PM

LemcottOP•12/17/23, 4:22 PM

ayyyyy

LemcottOP•12/17/23, 4:22 PM

that's pretty good

LemcottOP•12/17/23, 4:22 PM

I am happy with that

Nebulator•12/17/23, 8:08 PM

thats well within 0.2 deviation and is just fine. Im sure if you look at that peak that can be reduced as well. The dip in the middle can be bowing of the rail due to thermal expansion differences.

PSnewbie•12/17/23, 10:22 PM

Am I reading that wrong? The deciation looks like 1.7ish to me. High is 1.65, low is -0.07.

LemcottOP•12/17/23, 10:24 PM

1.655 is 1.732 away from -0.077

PSnewbie•12/17/23, 10:27 PM

The advice given to me was to get your deviation below 0.2 high to low. According to this your almost 9 times out from that

LemcottOP•12/17/23, 10:32 PM

The deviation isn't as bad as it sounds, the majority of that is in one peak where the flex sheet is slightly bowing up. I'm still waiting on a magnet to hold down the steel sheet.

Outside of that one peak it's closer to around .6 deviation. I think that's pretty good for my 3rd ever mesh on a custom frame. I don't want to do too much until the magnet comes in

Oskait•12/17/23, 11:36 PM

Have you tried leaving the sheet off?
My pinda worked fine on the alu bed alone

LemcottOP•12/17/23, 11:37 PM

I tried it but the activation distance for the pinda is suuuuuper close

LemcottOP•12/17/23, 11:37 PM

Like I basically have to put the pinda at the same height or below the nozzle

Oskait•12/17/23, 11:39 PM

and its better with the steel sheet?
I didnt really notice a difference in distance tbh.
But for checking your bed / frame it might be worth to just put the pinda lower or remove the nozzle.

LemcottOP•12/17/23, 11:39 PM

At least a ~1.5mm gain in distance before activation

Oskait•12/17/23, 11:40 PM

damn...

LemcottOP•12/17/23, 11:40 PM

On the steel sheet vs the bare aluminum bed

LemcottOP•12/17/23, 11:40 PM

Yeah

LemcottOP•12/17/23, 11:40 PM

That's like

LemcottOP•12/17/23, 11:40 PM

The suggested distance it be above the nozzle

LemcottOP•12/17/23, 11:40 PM

I definitely had a few emergency stops figuring it out mando

Oskait•12/17/23, 11:43 PM

yea my pinda is also very close to the print
and my first z-tilt worked on the first round, then it adjusted the bed and the nozzle crashed into it before the pinda triggered.

Oskait•12/17/23, 11:44 PM

do you have the RR superpinda or an offbrand one? I got the fysetc i think and was interested if theres a difference to the 3x more expensive one

LemcottOP•12/17/23, 11:44 PM

Fysetc

LemcottOP•12/17/23, 11:44 PM

Definitely seems to have the shortest activation distance of any on the market

Oskait•12/17/23, 11:46 PM

no idea never tried another inductive probe

PPSnewbie Am I reading that wrong? The deciation looks like 1.7ish to me. High is 1.65, lo...

Nebulator•12/18/23, 6:43 AM

Yeh I misread. It was late pog

LLemcott but I won't really be able to today (not enough spare time) Also I still can't ...

Fr3sh•12/18/23, 11:25 AM

I startet with the belt tensioning as well... same problem with the ripping off part

Oskait•12/21/23, 6:25 PM

Weird i didnt have that issue, did you fully insert the belts?
mybe try reprinting with a higher extrusion multiplier (maybe 5% more?) they're quick to print anyways

LemcottOP•12/21/23, 6:26 PM

I'll admit I'm using pa-cf
