@Phaedrux well i wanted to have them turn on automaticlly now i have to sitt and babysitt the first 2 layers just to wait untill layer 3 to kick the fans on.
that´s why i asked if it was possible to detect when the normal partcooling fan kicks on to also kick on the side fans.

now i have a macro that i start and stop the fans with buth i wanted it to be automaticcly

They are partcooling fans. that help cool bigger parts when i print fast so i have one on each side.
so i need to be able to shut them off when printing petg because they blow to much and make petg warp.
i tested changing pwm freq buth its prettty much the same the fans make weird noise no matter what i set.

Firmware i use is 3.2 b4 and i run duet wifi 1.03 with duex2

So i try´d to figure out a good way to solve this. but im stuck.
I Have a M106 fan that is pwm controlled and i have 2 bigger 80mm fans on the side with airducts aimed at the nozzleheight to get more cooling. they really dont like pwm and anything under 100% makes them scream digital noise.
Is there a simple way to make fans "see" that m106 is started and automaticlly turn on 2 fans on full?

@bearer said in esp32cam 5v power from expantionboard/duex 5:

the total 5v is what matters, but if the esp is the only additional 5v load its not a problem. there is just the one 5v source regardless of where you connect to on the duet (albeit there is a little difference in the length and width of the track, but for 300mA it doesn't matter).

what i can find by google
Turn off the flash lamp:180mA@5V; Turn on the flash lamp and turn on the brightness to the maximum:310mA@5V; Deep-sleep: Minimum power consumption can be achieved 6mA@5V; Moderm-sleep: Minimum up to 20mA@5V; Light-sleep: Minimum up to 6.7mA@5V

but i will remove the ledlamp as i dont need it so 180ma should be the load

so i ordered 2 esp32cam moduels just because they are able to output jpg stream to have a webcam on my printer to be able to look at them when im not in the room.
is it safe to run a esp32cam that draw maximum of 310ma 5v or is there another source on the duet that are more sutible?
1 of the printers will run a duet wifi 1.02 + duex 5
1 and one just runs a duet wifi 1.03

tried to find a suitable answer. but could not find any

o not at all neither look damaged but might be easy to just order them and swap them and se.
or is there any values that i can messure? i thr warrenty is already gone and i have some soilder skills. bust reslly bad at fault hunting.

Check L1 with a multimeter on the lowest resistance setting. It should have a very low resistance.

Check D2 using a multimeter on the diode setting.

BTW we are expecting to have new PanelDue firmware soon, to remove many of the limitations of the existing firmware. The new firmware will only work with RRF3 and it will probably be too large to run on version 1 and 2 PanelDue boards.

then i solve this board with scarapping it and getting a new thanks for the heads up

and i dont know if it helps but i tested it on a duet wifi 1.03 board

@dc42 said in Panel due v2.0 stopt working bit works with usb:

The V2.0 schematic is at https://github.com/dc42/PanelDue/blob/master/PCB/V2.0/schematic-2.0.png. UAB power feeds the power rail via D1, whereas power from the 4-pin connector goes via D2 and L1. So if it works on USB power, the fault must be with D2 or L1. Does either of those components look damaged?

The jumper should always be on 3.3v for common types of display. The version 3 PanelDue doesn't have the jumper, it's 3.3V unless you cut a trace and add a link.

no not at all neither look damaged but might be easy to just order them and swap them and se.

@Phaedrux said in Panel due v2.0 stopt working bit works with usb:

Are you trying to connect via the ribbon cable or the 4 wire cable?

Have you tried connecting it to the duet while it's being powered by the usb? You might be able to test if it's working at all or if something more is fried.

Posting some close up photos of both sides of the PCB could help to see if something is burnt.

i connect it with the 4 wires.
and yes if i connect the 4 wires and use a usb cable for power it works no problem i can controll the printer from it.

did not even knew that it was possible to rum the screen of a ribbon cable might try it out. should the jumper be 3.3 or 5v when connecting it with a ribbon cable? so i dont fry anything else

so i have an old 4.3" display with a panel due v2.0
after missing the 5v jumper on the paneldue and connected it to a skr board with lcp-rrf it dies. probably a tiny puff off smoke came.
now the weird part if i connect a usb cable to the paneldue the screen works and can controll the printer but it cant get its own power? what could be the burnt component is it worth trying to repair or should i just get a new paneldue?
