@phaedrux ill try to explain it a little better i have had this duet 2 wifi for over a year working great but recently i tried to hook up a a berd air part cooling pump directly to the pwm fan output and i think i blew the fan port or something because now ever time that turn off the power compleatly and i then try to move my x/y axis manually with my hand the little red led illumates near the usb in and i hear like high pitched wine as well when the led iillumantes

Hi I have had a duet wifi for a wile now but recently have had a problem with the led lighting up when I move my y axis and x axis even when there's no power going to the board I use a ac relay for a keenovo 800 watt silicone bed

I just bought a bondtech pancake stepper it's a+a-b+b- I did that and all it does is spudder its on a duet mastero board I tried switching the wires and nothing seems to work anyone know what I'm doing wrong

@dc42 thanks I'll try those

https://www.ebay.com/itm/264486995606 I think this one will work too

@dc42 so thst one works well with pwm control u can successfully control the speed?

I just found a 5015 sunon blower that's 4 wire its this model MF5015VX-C05C-S99

Is there any blower fans that are pwm capable they usually have 4 wires?

My sunon blower is only 2 wires and its ither on 100 percent power or it barely blows at all no middle ground

@Phaedrux I'll have to try that one that u put the link up for does it have 3 or 4 wires those usually work better for pwm I've found I've tried frequency as low as 100 Hertz up to 10000 Hertz with no luck

That's not a sunon it's a fystec and mine doesn't have 3 wires but I have another one that I'm gonna try that has 3 wires so thanks tho

Hi I'm wondering is there a blower fan in the current market that can be successfully pwm controlled like I've bought a sunon blower and it is really hard to control the speed its ither all on or basically no airflow I mainly print petg and nylon and I only need like fan on at 25 to 30 percent power if that I'm debating going with just a 40x20 4 wire noctua fan for part cooling also I just bought a second 5015 blower different company same deal I like the idea of blower fans but I cant find one that is good with only being powered at 30 percent speed

i just installed a duet 2 wifi on my cr10s and everything works great but it wont save my pid auto tune results with the M500 command and it also wont create a config override file ither anyone know whats going on here

Yes I changed the frequency and they at last turn on now I'm gonna mess with it further tho thanks for the reply

I just bought the normal 3 wire noctua fans one 120mm for my duet mastero mcu cooler and 40mm x 10mm for my hotend cooler but I set them at frequency 500 and they look like they tried to come on but didn't do I need to change the frequency

So I bought diff hall endstops that I can add a external potentiometer to so now i know i can adjust the trigger distance with my external potentiometer the three holes u see in the above pic are where u solder the pot to

I'll try to get that schematic but I'm thinking it might be hard to get lol

I'm not afraid to spend money but I want to be smart about it

I recently bought noctua fans for my e3d v6 heatsink and for part cooling but they actually suck at that job very weak and almost no cooling whatsoever so I guess I'm on the hunt for higher output fans but just dont want to keep wasting money on stuff that dont work as I thought it would I need advice I'm debating getting Noiseblocker brand fans but they are also expensive and advice would be much appreciated

Like this hall sensor has a pot built into it to adjust the trigger distance
