Hey Guys i had change my hotend to an rapido 2 plus uhf.

Had somebody as reference his cfg with an FilamAtrix with two d2f sensors with 5.5 mm Ball?
I mean the:

tool_stn
variable_retract_length
variable_pushback_length

Or are any cfg available for it?

#

Or can it be measured at the cad?

#

To get the correct values

thorn rivet May 16, 2025, 5:57 AM

#

I use this upper part

#

For UHF add 9mm

undone vigil May 16, 2025, 7:47 AM

#

yeah i had problems at the moment because the uhf get permanently stringing

#

so i am thinking about now what it could be , the new cw2 or the rapido

#

Had also an g2e here

#

i dunno at the moment

thorn rivet May 16, 2025, 7:48 AM

#

I use a Ge2 and have no problems

undone vigil May 16, 2025, 7:50 AM

#

Yeah i was thinking about change from cw2 to g2e

#

Have you also an rapido 2 plus uhf?

thorn rivet May 16, 2025, 11:32 AM

#

Yes, rapido 2 plus uhf ge2 twin sensor

undone vigil May 16, 2025, 9:48 PM

#

Yeah i print it at the moment

#

Had to modify also my servo arm for the g2e

undone vigil May 18, 2025, 2:55 PM

#

Tiny stringing anyway

#

Ive change the extruder

#

Ive change the hatbreak

#

Recheck the hotend

#

The only thing that are not changed are the hotend fan

undone vigil May 18, 2025, 2:56 PM

#

thorn rivet Yes, rapido 2 plus uhf ge2 twin sensor

which retract are u using?

#

could u also show me youre extruder section?

#

i have tiny tiny hairing

#

tested also with diffrent brands of pla

thorn rivet May 18, 2025, 3:05 PM

#

Ge2?

#

Have you changed your ratio?

undone vigil May 18, 2025, 3:05 PM

#

sure

#

Not mounted the first time

#

Whats your retract length and speed?

I have changed:
Extruder

Still stringing

Tested diffrent retracts

Diffrent temps

I cant get the rapido 2 plus UHF to run

Can you show me a video of how it extrudes?! heat and extrude 100mm at 10mms

Testing all Retraction Speeds , it looks like , with the g2e it wont take any effects

undone vigil May 23, 2025, 9:07 AM

#

So ive taken off the turtle from the printer

#

An see the stringing are gone

#

so what could cause on the turtle that issue <@&1304550334839918672>

thorn rivet May 23, 2025, 9:44 AM

Check this

Retrack e pushback

undone vigil May 23, 2025, 9:45 AM

#

that your values?

thorn rivet May 23, 2025, 9:45 AM

#

they must be changed according to the length of the nozzle

thorn rivet May 23, 2025, 9:46 AM

#

undone vigil that your values?

Yes

undone vigil May 23, 2025, 9:46 AM

thorn rivet they must be changed according to the length of the nozzle

Okay lets give it an try

#

We both had the same cfg

#

Extruder and hotend

thorn rivet May 23, 2025, 9:46 AM

#

Default is 20 or 25

#

I don't remember

undone vigil May 23, 2025, 9:47 AM

#

Yeah but your values are also for the g2e with rapido 2 plus uhf

thorn rivet May 23, 2025, 9:47 AM

#

Yes

thorn rivet May 23, 2025, 10:07 AM

#

what measurements did you put on stn?

undone vigil May 23, 2025, 10:07 AM

#

Coulkd you send me an 3mf sliced model with your cfg?

thorn rivet May 23, 2025, 10:08 AM

#

Ok

undone vigil May 23, 2025, 10:08 AM

#

I mean a project sliced with your cfg

thorn rivet May 23, 2025, 10:08 AM

#

Yes, ok

undone vigil May 23, 2025, 10:08 AM

#

I will, shopw you my stn etc

#

to compare

#

But at the moment i am without printing with any turtle

thorn rivet May 23, 2025, 10:35 AM

#

Do you want it in single color or with color change?

undone vigil May 23, 2025, 10:36 AM

#

Single

#

Do you have print the Filametrix or the Filamtrix?

#

thorn rivet I use this upper part

I have this

#

With part under UHF

undone vigil May 23, 2025, 11:04 AM

#

youre printing with 190 ?

thorn rivet May 23, 2025, 11:13 AM

#

Asa 245

#

Pla 215

#

Abs 245

#

But

#

minimum at 200-250mms 20k

#

300-350mms asa 260°

#

anyway, uhf drips a lot, it has a lot of material melted internally. if you don't have a printer that exceeds 300mms 20k mount HF

#

500mms 30k I didn't reach the maximum flow of the UHF, 45mm³. I reached the maximum at 32mm³

undone vigil May 23, 2025, 11:54 AM

#

okay my printing speed tested are 150 mms

#

XD

#

That it could be i am barely to slow

#

So the hf could be really enough

thorn rivet May 23, 2025, 11:57 AM

#

Mount HF, you have much less problems.

undone vigil May 23, 2025, 11:59 AM

#

okay will test it

undone vigil May 25, 2025, 9:21 AM

#

So after few days of testing

#

I was take off the fan of my cpap yesterday

#

Without cpap the stringing are gone

#

i need to go way to hot with pla that the stringing goes away

#

Like 270-280

#

with cpap

thorn rivet May 25, 2025, 9:33 AM

#

Uhmmm sorry, but you're not going to send the CPAP to 100%?

#

Pla 180-250mms 200% cpap 40-50%
Asa-abs 250-300mms 260° 5-7%

#

you have to calibrate each filament based on speed time and cpap. It is not that simple to calibrate

undone vigil May 25, 2025, 9:44 AM

#

i had

#

if ill take on the cpap with 10%

#

I need to go up with pla over 250 degrees

#

With the hf variation now

thorn rivet May 25, 2025, 9:57 AM

#

I don't now

undone vigil May 25, 2025, 6:24 PM

I had two diffrent heatbreaks for it, one version only screwed thermistor, and one with an Drilled Hole also in it

I dunno whats wron with that piece of S.......... But iam now Mounting my old one again iam finish with the secon rapido

Ive rote Phateus on Voron no response yet

undone vigil I dunno whats wron with that piece of S.......... But iam now Mounting my old on...

@undone vigil Never had these problems, I have 3 of Rapido 2 Plus. The latest version is without hole

#

You did the PID with the CPAP at 15-20%?

#

The strange thing is that you say that without Turtle it doesn't do it, as if the turtle didn't do retraction. Have you tried putting retraction on layer change?

undone vigil May 25, 2025, 9:45 PM

#

It was not the turtle

#

Yeah all the stuff

#

Its not my first rapido

#

I have one in my enderwire also

#

i had 6 printers

#

never had such issue before

#

I had now an Dragon clone in it the K1 Lizard v6 with that hotend it works normally

#

Only Hotend are changed now

#

So for me it is the Rapido

Currently I'm running a Rapido 2 UHF on a cw2 and I'm wondering what everyone is running for there settings and getting reliable results?

tool_stn: 58
tool_stn_unload: 80
variable_retract_length : 30
variable_pushback_length : 20

i find if i try to retract any more, i will start getting filament jams...
im trying to change how much purge i need to do on my prime tower and currently i have it set to 550 and i still get color bleed sometimes..

any help is apricated..

Thanks!

wanton monolith Dec 5, 2025, 9:50 PM

#

I am at 15 and 13 for retract/pushback, sorry don't run the same toolhead to help with the others.

#

why don't you let your slicer vary the purge volume?

raw zealot Dec 5, 2025, 9:52 PM

#

wanton monolith why don't you let your slicer vary the purge volume?

i could... set the multiplier to 1.1 or 1.2 seems to give me 550 flush for the two colors i know bleed with each other...

#

what multiplier are you running in orca?

wanton monolith Dec 5, 2025, 9:55 PM

#

1.0 but I have it set to like 30% +55 for length on the actual gcode output

#

I found printed the purge volume test between red, black, white, and another color to try to cover the bases

#

but I also run HF not UHF
