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

That's normal. When you move the motors by hand they act as generators. The stepper driver chips feed the power they generate into the fused side of the VIN supply.

When in doubt, find the pairs through measurement

@bigwood247 said in Blower fans for a duet wifi:

@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

The one I linked controls well down to 10%, though it doesn't move a lot of air through the duct at that point. Useful low range is probably 20% and at 100% it's very powerful.

@bigwood247 said in M500 wont save:

it also wont create a config override file

No config-override.g files exists in /sys?

What firmware version are you using? M115 to find out.

Do you get any errors when sending M500?

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

@zapta no clue, that's over my head. I just know from experience that magnetic and air "bearing" do not like to run below 100% and that was confirmed by a reply I got from some PRC engineers who's PLC's I was fixing on some glass machine, they explicitly said not to use maglev fans on few places as the fan's are PWM-ed below 100% ... and wrt sleeve / bearing / dual bearing you can find in the datasheets of the fan makers who make all different types, so you can compare the specs 🙂

I don't think I ever saw a spec wrt "moving env." but IMO I think our acceleration is way below any value that can really affect the miniature mass of the fan blades on the fans we use. And I had a steel "frame with 120mm fans" drop to a concrete floor from ~2m height while all 8 fans were running, acceleration strong enough to have sheared 4 M4 screws connecting that frame the the heatsink on the back, and fans continued to run, no fins got away 😄 ... so, IMHO, I doubt our moving head affects these 40mm fans or 5015 blowers in any way 🙂

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

@Phaedrux yeah I actually went down that route works good now thanks

How are you trying to add them and what is happening when you do?

In DWC you should be able to go to the macros section and there are buttons to create folder or file. You can also upload a file from your computer.

2.0.4 is a bit old at this point, perhaps best to update to 2.05.1 and DWC 2.0.7 that comes with that release.

So I started from scratch and just set it up with manual bed leveling for now I can always buy another dc42 ir sensor and set it up in a few days

K thank alot man
