Hi, i have already gotten help by you guys a couple weeks ago but have since updated my printer to CNC AB mounts, BFI and a couple other mods

#

would like to get your insight again to improve

#

graphs are coming

Are you using night hawk for the measurement?

Ye I know, it’s just that the cnc double shears are coming next couple of days and forgot to remove the bearing

Yes

lament marten Jul 6, 2025, 2:03 PM

I think you might have a potential bearing issue.

#

can you remove the bearing hanging out on top of the flag pole and see if it helps

It’s an emotional support bearing! Fake it till you make it

I got a 48v uhp power supply, installing it tomorrow

okay new update

#

Belts after 48v

#

running both motors on 1.4 amp

Can you remind me what your tension is please?

summer kettle Sep 25, 2025, 2:13 PM

#

lament marten Can you remind me what your tension is please?

let me check in 5 min

#

running some test rn, the toolhead board was loose

#

like it was only mounted with one screw

#

#

little better

lament marten Sep 25, 2025, 2:17 PM

#

You got about 4k more accel in ei

summer kettle Sep 25, 2025, 2:18 PM

running Y now

summer kettle Sep 25, 2025, 2:20 PM

#

lament marten You got about 4k more accel in ei

y looks weird

lament marten Sep 25, 2025, 2:24 PM

#

Can you check your frame screws?
also can you put printer on the floor please and rerun y input shaper

#

and you are using the toolhead board adxl?

summer kettle Sep 25, 2025, 2:28 PM

lament marten Can you check your frame screws? also can you put printer on the floor please an...

i have the printer on a moving table, i had the wheel unlocked.... locked them now and rerunning

yes

its now like this

lament marten Sep 25, 2025, 2:30 PM

double check your frame screws, and put the printer on the floor and retest

summer kettle Sep 25, 2025, 2:30 PM

#

lament marten double check your frame screws, and put the printer on the floor and retest

like the extrusion screws?

#

not the gantry ones right?

lament marten Sep 25, 2025, 2:30 PM

yes the extrusion frame screws

summer kettle Sep 25, 2025, 3:12 PM

lament marten yes the extrusion frame screws

i didnt find any loose screws

#

@lament marten x seems better y still almost same

lament marten Sep 25, 2025, 5:29 PM

I think you have to either increase belt tension or up the accel/hz

Can you get rid of the loop on the toolhead?

#

what toolhead are you using?>

summer kettle Sep 25, 2025, 8:14 PM

lament marten Can you get rid of the loop on the toolhead?

Yes

#

I’m using the nighthawk 36

#

What toolhead though are you using?

summer kettle Sep 25, 2025, 8:19 PM

#

Oh my bad read it wrong, using a jabberwocky

#

Just thought of it but the extruder is empty. Don’t have any filament in it, gonna run some abs in it now

#

@lament marten that should also help right

lament marten Sep 25, 2025, 8:20 PM

Have you printed a voron cube to see where we are at?

#

If not set both to ei and try printing a cube using 4k as ext perimeter accel

opaque merlin Oct 2, 2025, 2:02 PM

summer kettle havent changed belts but this is it before changing

yup, fresh cube with fresh input shaper config values sounds good

lament marten Have you printed a voron cube to see where we are at?

heating chamber now for a cube

#

ran these rn
