Noise apparent when Homing and subsises when no motion

@tecno Via the overridde Condig file i have PID set and tuned and it has been working

M307 H1 R2.429 C140.000:140.000 D5.50 S1.00 V0.0 B0 I0

Only when i started Increesing speed is when i started noticing the issue, hence why Im thinking it might be somthing a bit more indepth

@tecno the bed Has been tuned, and its quite the termal mass so its hard to beleve that there is temp swings of approx 20c

Hi guys

Ive built my self a voron V0.1 based arround a Duet 3 mini5+.
I have started cranking up the speeds and I started to knoticed an induced noise in the bed Temp, to a point wher the thermal run away kicked in and haults the print (see fig 1).

Figure 1

Has anyone come accross this issure before? Power supply voltage seems to hovver betwween 24.2V-24.3V ( Witch seems Normal, but tell me otherwise). Could it Be an EMI/ EMC issue to do with the frequency of the stepper motors, as it only occures while printing ?

I still need to do some more work to figure it out, Like read the thermistor values with a discreet meter and such. OR maybe do a frequency anslsys of the noise ( On an asside, is there any logging tools for heater temps so i can do this? ), but i woud love to hear if anyone has encountered this?

Thanks in advance
Cian

@dc42 , Thats understandable. Regardless of how good a product is, price will alwats be a factor

Raspi's in 3d printing arent a new thign , wether it be octoprint , the emeragince of klipper, or SBC Functionality in the duet 3 echosystem itsself

Recently ive been playing arround with some of thease, and in parrell working with the raspberry pi compute modelul 4, in other non 3d printing projects. It got me thinking intergrating a standerd main board with a dedicarted spot, heder, supply for it. Hopefully this would make for a cleaner expearance.

After a quick google there is things that people are working on somtrhing along theas lines but, personally I still have prefrance for the Duet ecosystem and RepRap Firmware.

NIce to haves would include the fillowing:

• Duet 3 mini5 iteration
• Built in supply for Compute module
• Ethernet out

In the next few weeks or so im going to try create a hat that could interface between the two, I would love to be in a position to have the time to rework the whole MB my self but i already have too many projects on the go. Nevertheless, if this is somtheing that could be moved to devolopment/ is in devolopment, I would be more than happy to help out. I currently just graduated form a masters in electronic engineering, to having a few more projects under my belt is allways a bonus

Thanks Guys
Cian

I don't.
I've been blindly following a range of form posted and blogs so could have removed it, is it need or not if so why?

Hi guys,

Picked up a Maestro a few weeks ago and enjoying the RepRap experience to date, however, I'm struggling to get the PID for my bed to save.

Id run the autotune, that would be successful, id then try to save it. After the tune, I can let it cool down then start a print job with no issue, however, if I power down the printer and try to start a job I get there dreaded

"Error: Heating fault on heater 0, temperature rising much more slowly than the expected 1.8°C/sec"

I'm using the following firmware and bord :

• Board: Duet Maestro 1.0 (duetmaestro100)

• list itemFirmware: RepRapFirmware for Duet 2 Maestro 3.0 (2020-01-03b3)

I'm sure someone has hade a similar problem if there is a thread similar point me that direction
if any further info is needed let me know

Thanks in advance
Cian
