@misterjtc Hi, I would appreciate if you share how did you find out stepper motor currents? Are these currents for original creator pro stepper motors?
It seems to me that config from github here is a bit off
I have Y axis layer shifts sometimes and extruder motors at 700 are clicking when they should not

Hi, don't know if it is still needed but I am still running 3.5.3 and had a hardfault today. I see that there is an update with bug fixes. Is there a fix for this or is it still in development?

An update about hardware:

• The old board was damaged for sure. I don't know how it's called, but something is wrong with how the 5v power is interpreted. When I connect it to USB it shows 1.1v. I use a replacement now.
• I installed the bltouch and it's working perfectly fine. Though I was concerned that it is glowing red and not violet
• I had to reconfigure my thermistors using multimeter, because the resistance values from the docs were wrong. And I was overheating my hotend. It was 270 instead of 230
• ordered an accelerometer supported by duet, will have to design a holder and set it up if I have the time and energy to do that)

Some words about 3d printing troubles)

• Had a lot of trouble printing PETG. Reassembled extruders and changed nozzles several times.
• For now printing 40mms but maybe later I'll try to use input shaping and pressure advance, though on small parts I am not sure that my printer can accelerate faster
• Had holes in my prints. I blame clogs and a bad petf tube. Also 60mms seems to be too high for small models

As for petg it seems that I need to lower flow value in cura. Standard esun petg profile is not working. Thought it might be moisture, bought a dryer, but it didn't help for PETG. Lowering line width and flow seems to help a bit.

I am glad I did that upgrade. Learnt a lot about printing and electronics. And the printer is silent enough that I am sure no neighbor hears it.
Auto bed levelling is a miracle
Wifi interface is a miracle. I need only to push one button to turn my printer on and then I can just sit and control it from distance.
This upgrade made my printer usable at home and a lot more convenient to use.
I learnt a lot and I am in total control of my printer now
Thanks for your help and attention)

Hi, is there a working solution for ERCF? The GitHub at the start of this thread seems abandoned

It will be great to stick to RRF & DWC, but if it's not supported in future it might be a reason to switch to klipper

I fried my first board I guess.
New board is working fine

But that was not the end of the story...

Spoiler: I fixed it

So I noticed several things about my printer and here is the list of what I noticed and done to my printer

• First of all, my SD card was corrupted several times. And I ordered an industrial SD card as it is recommended in the docs. It works fine. I had no issues with that.
• I noticed that my extruder fan is too loud and I thought it might help to replace it. It did help to reduce the noise though.
• I had to replace my new thermistors because I had a clog and I damaged them while removing the clog
• While removing the clog I noticed that my grounding cable was loose and I fixed it better
• Then I thought something is wrong with my stepper motors config and I found out a lot about their tuning process. And in the process I even made my printer work without bed heating and low motor currents. I also found out that I like how silent is the stealthchop, especially for Z axis.
• I measured the current of my bed with a clamp meter and it is about 8-9 A, so it's 200w
• I found the config here for duet 2 wifi config
• I found out why I might have problems with my stepper motors. Because there is only one man who tried using duet 3 mini 5+ on this forum that I know of. And TMC2209 have to be configured.
• I noticed that z axis motor is producing a very loud hissing sound in standstill spreadcycle mode
• I removed another loose grounding cable near the sd card.

And after all that I was lost. The only thing I had in mind was to replace the board.

• while setting up a new board I had to reflash the firmware several times, because it was always busy with something. So if I closed up the connection and had to change something in it again it won't connect to my mac until I push the reset button two times and upload the .uf file to the bootloader

And changing the board helped. I might have damaged the old one with a short.
I also took a precaution and removed another screw that was underneath the board.

The one thing that I noticed right away is that the voltage shown by the new board is higher
And I also had some hard faults on the way, but for now I just want to rest a bit)

I'll post my config some time in the future when I am sure it produces the best results, but for the most part I use the one mentioned earlier from github + my settings to enable spreadCycle almost for every move except standstill.

@gloomyandy Hi
It's a Fysetc Big Dipper board

You didn't answer my question though)
I also want to debug this problem, but for now I can't understand what to look for exactly.
As far as I understand brownout means that the power was lost
Though the voltage is fine
The 450w PSU for FFCP should be fine
I checked my wiring lots of times now and I did find a lot of mistakes
If I have something wrong it's not obvious for me at all

This thing happens to the printer after a few minutes of printing
If I restart it happens almost at the same time

Hi, can you help me understand when a board gives a vdd brownout error?
What triggers this event?
What sensors this event is based on?

Hi, want to share some news

I changed my PSU to Meanwell LRS 450w - it fits (35 mm height is good for FFCP)
I installed creality 40w 24v heater catridges
And I still had vdd brownouts after that. Though the board restarted and showed the error every time. So it was another issue.

Recently I got used to checking all the cables. And I had a guess that something is wrong with my extruder motors. Because it was only during the print that a printer would give a vdd brownout error and restart. So I checked my stepper motors cables and it turned out all that time I also had loose connections on my stepper drivers So I recrimped them. And that time I also had a "pull test" of my cables while holding multimeter and checking the resistance.

I hope now I'll be able to continue refining my config and help dc42 with debugging

@infiniteloop Thank you for your thoughts, I think that I use all of your advice, but I lack experience, so I can't be as good as you before I get some experience)

My strategy is "try and fail, but do not stop".
I've learnt a lot about my printer in a month) If I were too afraid to change the config or hardware I would do nothing and just throw my printer away.

The thing that I lack about the DWC is git.
It would be great to have a VCS for configs.
But I can always create a repository myself

Where do these figures come from?

Here is the tuning discussion, I used this number for E jerk on purpose
https://forum.duet3d.com/topic/6181/tuning-macros-menus-accel-jerk-retraction-pressure-advance/18?_=1728802639093

guys are saying that E jerk should be high enough so that it doesn't "cap the X and Y jerk values for a print move"

All units are mm/min, so why should Z be limited to 12 mm per minute(!)

That comes from the config generator, I didn't change that because Z axis seem fine.

This line carries no comment,

The one for the Extruders has it. I lost the one for axes when copied the config here

separate entries for axes and extruders.

that is also how the generator creates a config today

@infiniteloop

but how can you explain the failure on the right?

The config I posted is for the left print
The fact is that low jerk and acceleration settings helped achieve a good result

@infiniteloop

But didn't you tell me that the PSU never turns off? Or did I misunderstand something? In this context, you also mentioned some LEDs never going off …

I meant that when there was a shutdown, nothing happened to the PSU, it was the board that stopped working

At first, before I grounded the board, I witnessed the board shutdown and turn off wifi. The lights near 5v switch were blinking with no pattern. But the 24v power LEDs didn't show any signs of trouble.

All that is in the past now, after I removed the screw

Learn where to draw the line between RRF and Cura:

That's actually a nice thing to mention. I think that the Printer Settings plugin makes things a bit more difficult)
I'll have to check what it does, besides the setting that I set for firmware rectraction when I explored tuning tutorial yesterday

I have to take care of my dog and some other stuff, but then, we'll deal with your config.g. CU

Nice of you to put so much energy into helping me, but please keep balance and take care of your dog)

That's my config right now that produced the best results.

At these jerk and acceleration for axes I have no layer shifting. There are some underextrusions though

Slicer: Cura
layer size: 0.3

@infiniteloop

Looks like as soon as you happen to touch one problem, a bunch of others surface seemingly out of nowhere

Yeah, sorry, it might look that way. But really the biggest concern was the restarts. And here is your portion of success story, after I removed the screw I am able to print.

Hard faults don't bother me too much.

Layer shifting does, so that's my next problem

I even figured out that eventually, these things from the moon are rated at 1.5 A

That's great. I wonder how you did that?

@infiniteloop

Is the power outlet you use protected by an earth leakage circuit breaker? Is there any one of these installed in your house?

I guess so

I can’t figure out how the board is switched off

It is the Flashforge Creator Pro and it has a button behind it to turn off the power that goes to the PSU

Glad you spotted this one. Keep reporting on how it works.

Now I finally can focus on configuring other params because it works fine. I had two hard faults though.

To check if some component inadvertently bridges to GND

Before I started printing I checked once again, and ground wasn't connected to other pins.

Don’t know how the steppers are currently configured. The section Stetting motor currents in the support document
Configuring stepper motors provides detailed infos - I think even more than you ever wanted to know.

As fas as currents are concerned I think I'll monitor motors temperature, for now they are not even 50 degrees hot and they say that's fine

I found macros for tuning the speeds, jerk and acceleration here https://forum.duet3d.com/topic/6181/tuning-macros-menus-accel-jerk-retraction-pressure-advance

And that's what I am going to focus on now

Finishing the test print without defects

One of the main problems for me is the layer shifting for the y axis

Hi, I have a Big Dipper board with 3.5.3 installed

In case it will be of any help

Ok, yesterday the printer was working for hour and a half until I turned it off. The motors were about 50 degrees celsius and I guess that's why the layers shifted. The current was set to 850 ma for xy and 400 for z, and 900 for extruders

Today I changed the config but the print failed with the HardFault

I started the print, it looks promising, 25% done

Now I googled the datasheet for moons stepper motors (17HD4063-06N) that are installed on my FFCP, and as far as I understand they have a rated current of 630 mA, so I should change my config.

063 / 100 = 0.63 A for the Y axis at least

and for the extruders my FFCP has two 0.8 A rated 42HB34F08AB-22

Ok I found an accidental connection between the right extruder pin and the ground
For some reason I was confident that nothing is touching the board. Thank you all for your ideas.

Now I measured all other connections and see that my 24v+ PSU is connected to e0, e1 and bed + and - pins

And the resistance between the - and + for the board power pins and the bed power pins is about 160 oms
Is that ok?

@infiniteloop Hi, thanks to you and idea came to me to measure resistance with a multimeter for different connections of the PSU
And I found out that I have a direct connection (multimeter beeps) from PSU 24v to the ground when right extruder is connected to the board

Also the resistance between the ground and PSU 24+ is about 1500 om

even without my cables attached that connect the board and the extruder to the ground
