Heaters problem

Phaedrux

Can i use the pwm fz in Q1

Yes I think so. I think I've used it in the past to stop the pot lights from flickering. Give it a try.

The video definitely shows more audible clicking that I would expect. But maybe my noise floor is a lot higher and I just never noticed before.

Phaedrux

After doing a heating of the bed can you send M122 in the gcode console and post the results here please?

dc42

Mosfets do not normally make any noise, so I suspect the noise is coming from somewhere else, e.g. the PSU, or the bed heater itself.

@Phaedrux yes i send m122 when the bed is to 60° degrees that show me:

@dc42 maybe is the power supply tomorrow can i try other one, and i don't think is the hotbed because whit the hotend have same problem. And today i changed the thermistor and wires from the bed for new ones to try and nothing I got same problem.when I'll try the power supply i say it here, thanks for yours attention.

erwaly

@dc42 I tryed other power supply today the same one 24v 15a 360w, and when heating it the bed,in the new power supply is burned to 160ohm resistance... I so strange because the first one don't have nothing burned and work fine just the sound...i buy a new hotend for extruder a new hotbed, tomorrow i try the extruder, the bed is take more time to come, but a say anything here when i change it. Thanks for their help.

erwaly

@erwaly finally i get a new bed and new hotend, i got a logistics problem whit the send and coming today, i try whit new bed, new thermistor,new wires and different power supply and i have the same problem. Whit the new power supply is less sound but can listen it... I think maybe can is a bad update, i don't remember whit what firmware comes not sure but maybe 1.21 or 2.02 i buy it on 2019 but never use before. I want to downgrade the software and new upgrade, what is the best firmware to start? From 2.0 and up or better from 1. 21 and up

Phaedrux

I'm not sure what you mean. Did you have firmware 3.2.2 running as shown in your M122 above?

@erwaly said in Heaters problem:

Duet 2 WiFi/Ethernet version 3.2.2

erwaly

@phaedrux yes i have 3.2.2 now but i want reinstall and new update, what is the best software to start ne install from 0... 2.00 or 1.21,or 3??i think maybe i don't install one file from old updates.

Phaedrux

I really don't understand what you're asking. What are you trying to accomplish?

erwaly

@phaedrux I think that when I updated my motherboard I made a mistake and some version did not install well. I want to do a clean installation by deleting everything with bossa and installing the board from 0, the thing is which is the best version to install and update, or do I directly load the 3.2.2 again?

Phaedrux

Ah ok. Well if you have access to the board via usb terminal or DWC currently working you can check the installed firmware with M122 or M115. If it's 3.2.2, you're good to go.

If you want to reinstalled everything and you have access to DWC you can just upload the full zip file for 3.2.2.

https://github.com/Duet3D/RepRapFirmware/releases/download/3.2.2/Duet2and3Firmware-3.2.2.zip

If you don't have access to DWC and you want to reinstall the firmware with BOSSA use the combined firmware file from that same zip file.

https://github.com/Duet3D/RepRapFirmware/releases/download/3.2/Duet2CombinedFirmware.bin

And put the DWC files from this zip file into the /www folder manually.

https://github.com/Duet3D/RepRapFirmware/releases/download/3.2/DuetWebControl-SD.zip

erwaly

@phaedrux If I have access via web and usb that is not the problem, the question is if I erase the board and install 3.2.2, that version has all the necessary files or should I first update to 3 and then 3.1 ... to 3.2.2

Phaedrux

If you're using bossa to flash the board you only need the version you intend to use. After you're up and running though it's probably a good idea to upload the zip file release via the web interface to that all of the other IAP files are present for the next time you want to update the firmware.

In general, if you already have DWC running, just use the zip file upload method.

erwaly

@phaedrux So update ok, reinstall by bossa and upload the files to the sd. Really everything works well, it is only when heating the bed or the hotend the power supply beeps as I showed in the videos, I already tried to change everything, I even tried 2 sources and the problem continues, I only have to try another plate ... I don't know what can be failing, change cables, thermistor, hotend, complete bed, 3 different power supplies and keep beeping when it reaches the indicated temperature.

Phaedrux

Can you identify by ear where the noise is coming from?

erwaly

@phaedrux yes the sound is made by the power supply when the bed mosfet or the hotend cuts and opens, I have tried 3 different power supplies and the sound does it with all 3.

Phaedrux

What brand of power supply?

erwaly

@phaedrux one is Creality 3D DC 24V 15A 360W, the other two are Chinese from amazon NEWSTYLE DC 24V 15A 360W

Phaedrux

Might want to try and get a genuine MeanWell and see how that goes.
