Hi, I’ve been wondering how to make my sv06 ace more silent, previously I had a ender 3 pro and with the quiet step motors it was very quiet, but with SV06 ACE I can’t even leave the print in the other room over night because it’s too loud to sleep, the main issue is the print fan, has anyone seen any drop in replacement for the default fan or a printer shroud for adapting another type/size fans?
I’m not sure if there’s something wrong with my fan since I’ve seen people complain about MCU and PSU fans which for me in comparison are dead silent.
I’d be grateful for any help, or a pointer where to find a 3d model of the extruder so I can try to model my own adapter.
The fan isn’t comparable to other component fans. It spins significantly faster than usual. Even with PLA, it only spins at 70-80% with the Orca settings. The nozzle might help a bit, but I don’t hear anything from the power supply fan or electronics fan during printing.
This is what I was hoping to find, thank you so much to you and everyone else that has contributed, I will let you know how it works after I get to it, lets hope my wife won’t complain about the printer in the living room anymore
Hi,
I have a sv06 ACE and it was incredibly loud! I have replaced the mainboard fan and case, door side only with a high flow option. I have retained the size of the original fan by using an ANVISION DC 24V 40mm Dual Ball Bearing Brushless Cooling Fan, YDM4010B24. I sourced it from amazon. It is a direct plug and play replacement. It is still not quiet but a lot quieter than it was. I will be looking at now replacing the PSU cover and using a larger silent fan, as this is now where a lot of noise comes from. With regards to the Print head fans. I am looking at replacing the 4020 with a DC Brushless Cooling Blower Fan 5015 50x50x15mm Turbine Turbo Dual Ball Bearing Centrifugal Flow Blower DC24V 2 Pins for the heat chamber, again avaliable on Amazon. But not sure the hot head (nozzle) fan is something I would look at upgrading.
So to recap, you can swap the noisy Main Board and PSU fan that will make a difference, but the head fans I would think about as that is more for long prints and different filaments…
I hope that helps.
I’ve been dealing with this too. It’s quite loud and I am certain it is the part cooling fan. Unfortunately, the biggest challenge has been finding a 4-pin PWM solution that is compatible.There are just very very few 4-Pin blowers out there, 12V, 24V, or otherwise. The ones I have found are huge, like this 97mm x 33mm one.
Noctua does have plenty of 4-pin PWM options, however they are all standard axial fans, no blowers. This means that pressure and flow leave much to be desired, especially compared to the stock SOVOL ones. Especially since this is a ducted part cooling fan, the pressure is important.
Noctua also sells a 24V to 12V PWM-compatible buck converter (Noctua site, Amazon US Link), but this doesn’t solve the problem that regardless of voltage 4-pin blower fans are difficult to find.
Has anyone else had any luck finding a quieter part fan which would be controllable through the 4-pin? Or is there a way to convert the PWM mode from the fan header on the SV06 ACE to a 2-pin PWM paradigm?
In terms of other 4pin pwm solutions you could just ignore the PWM option and plug the fan straight to the GND and 24V pins on the board, it would mean the fan can only run 100% but for PLA that’s the plan anyway. Properly converting 4 pin control to a 2 pin fan would be difficult but you could simply connect the 4 pin GND to GND and PWM signal to the fan power supply, if the PWM signal is capable of providing high enough current it could work.
The connectors I need should arrive tomorrow so I can update you on the pinout of the connector and if this solution prints properly then.
EDIT: After typing out the answer I realized that PWM signal is unlikely to be 24V, but I can measure that tomorrow, and here’s a schematic of how to get around that with a 2pin fan. You would need an external FET but that should be all you need and work fairly well. In this scenario Im not sure how would the controller behave without the TACH signal
Klipper doesn’t care if your fans have a tach signal or not. MANY printers use 2 pin part fans. Sure it is nice to see fan speed on the display but it’s not mission critical.
[fan]
pin: extra_mcu:PB0 #FAN3
max_power: 0.8 #adjust to noise vs cooling ratio to suit your taste
#tachometer_pin: extra_mcu:PA3
#tachometer_ppr: 2
#tachometer_poll_interval: 0.00125
Did you wire them in parallel off “fan 3” or hook one to the open fan header on the toolhead MCU? if you paralleled them you can only read speed from one.
I assumed guys would use generic 2 pin fans in parallel and didn’t consider the errors Klipper will throw if the tach pins are left enabled.
If you run off the open header you’ll need to tell your slicer OR write a macro to intercept fan speed gcode and command both fans to the same PWM.
The 3d model for the SV06 Ace is available on Sovol3d’s github. The “Max” isn’t BUT the only differences are lengths of rails, lead screws. bed size and such. The tool head and X axis carriage are identical.
I intend to pararell them since I don’t think reading the speed from only one would be much of a problem since with the same PWM the RPM should be close enough. Your comment made me realise I should probably remove the tach signal from one of the fans.
