#How is this looking?

I just finished up the build and some mods, I'm curious.

polar ocean
#

A lot of people would envy such clean single peaks. Mostly me I am cursed.

#

How does your belt chart look?

fleet flume
#

I installed BFIs, swapped from Moons to LDO, and redesigned the stock XY joints to use 5x18mm pins

weak sentinel
#

@fleet flume can you post all the graphs please

#

We need to the complete story

weak sentinel
#

In y it looks like peak 2 might be your umbilical. Can you post a picture of the front of your printer. And can you print a voron cube as a baseline before we mess with anything please

fleet flume
#

I'm having problems with my dragon clogging but I will

weak sentinel
#

@fleet flume take a look at the post #1308097646786777108 There is a video about umbilical there

It causes too much drag on the filament

#

We only want 1.9 between extruder and hotend

#

Spool to extruder should be >=2.5

#

Highly recommend to replace it as this can cause wrong EM and PA values

fleet flume
#

Cool. I'll order some

true crater
#

Totally unrelated to your post but thought i should mention it

true crater
fleet flume
#

Well I'm fighting a clogging issue, too.

true crater
#

Its quite possible the 1.9 is causing it

fleet flume
#

I'm waiting on a better 4010 to get here too. I did order a new 5015, a GDS time hydraulic bearing. I bought it to replace the Doceng that came on the printer. The GDS time uses quite a bit less current so I'm wondering if I should just leave the DOC eng in there

true crater
#

They wear out fast under our conditions

#

We always want double bearing

true crater
#

Make absolutely sure to buy it from a known good vendor

#

A lot of fakes around, especially on amazon

fleet flume
#

I'll get one from filastruder

fleet flume
#

On the belt comparison. What's the number I'm trying to go for? is 100% achievable? 99+% good?

weak sentinel
#

Your belts are fine

fleet flume
#

I'm rerunning everything after moving that cable

weak sentinel
#

All your graphs look good.
Peak 2 Indy is likely umbilical

fleet flume
#

This is with pins on the front idlers, and pins in the XY joints with GE5C Z joints. If any of that matters.

Yea, I'll try to print something after this is done running. In the midst of this post a clogging issue came back that I thought previously was fixed. I'm waiting on parts so I figured I'd line out I could on input shaping.

true crater
#

Please dont print “something”, the guidelines mention whats needed to be printed

Confirm via klippy.log that its actually being used

@fleet flume side note: white is horrible for test prints

fleet flume

#

Black is okay.

fleet flume
#

Getting ready to print a Black cube. Quite the difference in readings from the testing when I disable sweeping.

weak sentinel
#

Y is showing umbilical

#

Peak3

fleet flume
#

Petg seems wet so I tossed it in the dryer.

#

ALso, The EBB36 mount I'm using doesn't seem that solid. I found a remixed version that is more rigid so I'm going to try that out. Is there anything I can do about the umbilical showing up?

fleet flume
#

Going to have to back burner this yet again. The stupid clog is still happening.

fleet flume
#

I ran input shaping again after putting in the new fans. I dropped accel down to 4,000 from 5,000.

true crater
#

i would say we are done here 🙂

fleet flume
#

Sounds good, thanks. What would be the next steps if I wanted to squeeze some more accel out of it?

true crater
#

2WD 9mm

fleet flume
#

Sounds like 4k is about the limit without a major overhaul.

I had some Hiwin rails so I decided to swap them in for XY and used the stock Y rails for backers on top of the Y extrusions. It looks like the shape stayed the same but the power changed. Did I gain anything?

weak sentinel
#

Can you post an updated cube using ei

fleet flume
#

But this was with mzv on both, 57.8hz on X and 37.6 on Y.

weak sentinel
#

@tame lavawhat are your thoughts?

@fleet flume I am not seeing resonance per se. What I am seeing on the right hand side of the prints is more PA.

There might be slight woodgraining going on.

In addition, it might be bad speeds (vibrations profile).

fleet flume
#

I retensioned the belts. and ran everything again before printing that black cube.

weak sentinel
#

run vibrations from 0 to 400 mm/s

fleet flume
#

I also noticed my outer wall speed is at 60mm\s and that's right as it's about to hit the fan, too.

#

I did rerun a PA test after the grey cube, dropped it from 0.04578 down to 0.038.

weak sentinel
#

try dropping down to 0.03 with a smooth_time of 0.02

fleet flume
#

I will after the 400 mm\s run, taking a bit.

weak sentinel
#

This looks really good. Avoid all peaks in angular speed profile

fleet flume
#

Looking at that, 60 mm\s should be fine for outer walls so I'll just reprint the same gcode with the PA smooth_time changes.

weak sentinel
#

I would set outer walls to 120

#

60 is to close the rise in the peak

fleet flume
#

I'll change that, anything else?

#

Same gcode, different PA\smooth time.

weak sentinel
#

what PA value

fleet flume
#

0.03

weak sentinel
#

what size nozzle

fleet flume
#

0.4mm

#

CW2 on. Dragon SF

weak sentinel
#

I think you need to go to #slicers_and_print_help as the issues you are seeing are more print related than resonance related

#

The other thing you can try is to switch to EI from mzv

fleet flume
#

On both X and Y?

weak sentinel
#

Yes, ei on both x and y

fleet flume
#

Will do. Here's the 120mm/s cube.

fleet flume
#

Ran out of filament so I'm switching over to grey again. Looks like it was still there though

weak sentinel
#

I think #slicers_and_print_help is the place to go

fleet flume
#

I'm there, first response was asking about running input shaping, lol

tame lava
#

Is this tungsten carbide or Diamondback nozzle?

#

Gap fill ar 110 mm/s will cause artifacts, it needs to be at 40 mm/s. You can try higher later but I know higher gap fill speeds cause artifacts.

#

Check bolts that hold toolhead against the rail and all toolhead bolts, including hotend bolts.

#

That repeating pattern after some corners can be loose toolhead or PA related.

Not ssure if I should start a new thread or revive this one, so if this is the rong thing to do, sorry. A lot of disassembly and reassembly happened during when ended up being an extruder stepper problem. Now that the dust settled from all that, I can't get my belt comparison any better than this. What would cause that spike on Belt B? I haven't done any other input shaping because of this bad graph. Any ideas on where should I start?

If your prints look good for you I would stop and enjoy the printer.
can you post pictures of a test print pleas
