@T3P3Tony Thanks. I had a more accessable ground going to my filament runout sensor so I ended up using that.

@dc42

Well, I messed up and I think I need to replace some MOSFETS for Fans1 and 2.

I was trying to connect a 3 wire part cooling fan and I accidently shorted the GND of the 3 wire fan to the PWM GND of Fan1 and I saw a little smoke come out of the new 3 wire fan.

To try to determine what exactly I broke. I tested the fan fuse and it is fine.
I took a known good fan and connected it one at a time to
Fan0, used the M106 P0 S1 command and it turned on
Fan1, used the M106 P1 S1 command and it wouldn't turn on
Fan2, used the M106 P2 S1 command and it wouldn't turn on

I saw this post where you indicated that the MOSFET most likely went out.

Am I correct to assume that means that I need to replace MOSFETs for both Fan1 and Fan2 with PMV20XNE?

I have a hot air station but I wouldn't say I am great at it. I could use some recommendations on temps for removing the existing part and putting the new one on.

Thanks in advance.

Printer: Ender 5 Pro,
Mainboard: Duet2 Wifi
Extruder/Hotend: E3D 24VDC Hemera Revo
Part Cooling Fan: 24VDC ebmpapst 5015, model RLF35-8/12N
Bed Sensor: BL Touch

I have an ender5 Pro that I am updating to use this new fan duct design for the Hemera Revo + 5015 epmpapst blower.
https://rene-jurack.de/well-engineered-hemera-fan-duct-2/

The part cooling fan that I am removing only had two leads (PWR & GND). The new fan has three leads, one for PWR (red), GND (black), and PWM (blue).

I found the following post that describes how to connect it to the Duet2:
https://duet3d.dozuki.com/Wiki/Connecting_and_configuring_fans#Section_Connecting_3_or_4_wire_fans

My current fan connections are:
PWM Fans V_FAN connected to Red PWR
PWM Fans FAN0(-) connected to Black GND

On Duet 2, for 3-wire fans, the recommended connections are:
Red (PWR) of an always-on fan connector.
Black (GND)
Blue (PWM control) connect it to the FAN- pin of your chosen controlled fan connector.

Question:
Before I start changing connections I wanted to ask about the GND. I am attempting to connect this new fan without fishing another wire up through the to the hotend. I am only missing the GND for the new fan connection. The only GND wire I have going to the Hemera that I could splice from looks like the GND going to the BL Touch.

I know that for a two wire PWM fan the GND is the PWM control and you cannot bond that GND with other GND wires. However, for the three wire fans I believe it will be OK to bond the GND of the part fan with the GND on the BL Touch since it is truly acting as a standard GND. I wanted to get the forum's experienced opinion on the matter. Is it OK to bond the BL Touch GND with my three wire ebmpapst GND?

My new connections would be:
Always On Fans V_FAN connected to Red PWR of 5015
Splice the GND going to BL Touch and connect to GND (Black) of 5015
PWM Fans FAN0(-) connected to Blue (PWM Control) of 5015

@PaulHew

I ended up commenting out the "G31 Z0" near the top and changed the "G92 Z5" to "G92 G10" and now I have enough to get to the bed and complete the macro.

I am all for using built in leveling but I haven't found anything that seems to be as quick and accurate as something like this macro. I tried this process:
https://duet3d.dozuki.com/Wiki/Using_the_manual_bed_levelling_assistant

Numerous times and it ends up being a giant game of go fish. Just no way to adjust a knob based on a fraction of rotation and get any kind of accuracy out of it. Just constantly missing the mark and the number of iterations takes far longer than just running a macro like this to tune it in. I am all for learning though. Perhaps with some clarification I might see how the M671 is supposed to be faster or more accurate?

@paulhew

Appreciate the reply. This is going to be helpful to get to the bottom of this.

The Bed.g file actually defines that you are doing a four point bed calibration. It is the coordinates of your four adjustment screws and not defining that you have steppers at those screws from my understanding.

Please expand on the bed leveling built into the firmware. If you are referring to this:
https://duet3d.dozuki.com/Wiki/Using_the_manual_bed_levelling_assistant

I haven't found that to be useful at all. After it completes it tells me some rough fraction of a turn on a knob which is anything but accurate. I find that it is far more convenient and accurate to actually adjust the knob until you get contact. Please elaborate if I am misunderstanding the built in feature but I have used it and haven't found it to be faster or more accurate. In fact, quite the opposite.

I have recently replaced some parts and need to bed level again.

I am running v3.4 firmware. I tried to run my trusty macro that I got from somebody on here (@Phaedrux ) perhaps. But for some reason, even after I have properly set my z-height, this macro won't let me touch the bed with the nozzle. Instead it lets me drop the Z down to 0 but zero is way above the bed. I commented out the reset Z height at the top and I still have the same problem. Can anyone spot what the issue is? Do I need a command at the top to ignore z height? If so, this confuses me because I believe the z-height to be correct already. Before I run this macro I can decrement my nozzle down to the bed manually and it touches the bed right at 0. What is this macro doing that raises the Z height so much when it runs?

Also, before someone asks, I am aware of the following:
https://duet3d.dozuki.com/Wiki/Using_the_manual_bed_levelling_assistant

But it also seems to be out of date as those macros do not work either and I get errors when trying to run them.

If anyone has a handy dummy proof manual bed leveling macro to use with a BL touch I would be much appreciated.

@mitch said in 3.4 RC assign how to assign PS_ON?:

PS_ON

In case anyone else had the same question:

M81 C"pson"                    ; Turn off 24VDC power on start up and enable control in the UI
M950 J0 C"^exp.e6stop"                                 ; create GPIO input pin 0 attached to Estop6 expansion connector - Senses Power Button, Low=Button Pressed 
M950 P1 C"!exp.31"                                     ; create GPIO output pin 1 attached to heater7 on expansion connector - Controls Duet2 On=S1 (default), Off=S0
M581 P0 S1 T2 C0                                       ; When E6 goes Low, execute trigger2.g to complete shutdown

Prior to the 3.4RC upgrade I had been using the following configuration for 3.4Beta1.

I saw the release note regarding:
"There is no longer a power supply control pin assigned by default (in previous firmware versions, PS_ON was assigned by default). Therefore, M80 and M81 will not work until you have assigned a power control pin. If you want to control the power supply, you should use assign a pin using either M80 or M81 with the C parameter in config.g. Use M80 if you want to start with power on, or M81 if you provide separate 5V power and you want to start with VIN power off."

However, it is still unclear to me what I need to do to define PS_ON.

This is what I was prev using on 3.4Beta1:

; Soft Power Control
M81			; Turn off 24VDC power on start up and enable control in the UI
M950 J0 C"^exp.e6stop"                                 ; create GPIO input pin 0 attached to Estop6 expansion connector - Senses Power Button, Low=Button Pressed 
M950 P1 C"!exp.31"                                     ; create GPIO output pin 1 attached to heater7 on expansion connector - Controls Duet2 On=S1 (default), Off=S0
M581 P0 S1 T2 C0                                       ; When E6 goes Low, execute trigger2.g to complete shutdown

@phaedrux
That worked.

Attempts to upgrade via the web interface from 3.4Beta1 to 3.4beta7 fail with an error stating that the Duet2_SDiap32_WiFiEth.bin file is missing from the firmware directory.

Looking in the firmware directory I only see two files:
PanelDueFirmware.bin
Duet20CombinedFirmware.bin

I found a copy of the missing file in my sys folder, copied it into the firmware directory and then attempted the upgrade again. No errors this time, but it doesn't seem to have upgraded.

Well, so far so good. I ran a twisted pair and terminated new connectors. One of the two seemed to have fixed this issue for now. Thanks for the help.

@Veti Ok, doing that now. I know I read something somewhere about 4wire vs 2wire on the PT100. Right now I am just running a straight 2wire.

Running a separate twisted 2wire now.

The PT100 wire is not twisted pair. It is just a straight through cable. However, all of the motor cables are in fact twisted pair.

Is tearing this wire bundle apart and using twisted pair for the PT100 sensor a necessity? If that would eliminate this issue I have not problem doing it. But it is quite the task if it isn't usually necessary.

I am attempting to run a print right now. The blips in the graph are heater faults I have had to clear. The temp just seems to stay on and then drift, clear it, it works again. Not spikes to 2000 or anything like that.

This may be a combination of some macro issues due to recent firmware updates as well as an intermittent connection near the hotend probe.

Thanks for the help. I am going to try to nail down the probe issue first to start to rule out some variables and make this easier to figure out.

@jay_s_uk Thanks,

I updated the file. Seems to still run the same. But I will make sure to find all the macros that have this command and add the quotes.

Just seems like sporadic behavior.

After trying numerous times the macro just started running. Part way through I got the heater fault.

@mitch said in PT100 sensor on Duet2 sporadically hunting for target temp:

M98 P/macros/general/1_Center_Nozzle

This is just acting really strange. I can put the lines into the console one by one starting at line 79 and it all works fine. But when I run the macro it just seems to get to around Line 79 and then just exit. No errors or warnings.

Yes it does.

I commented out the Tone generation and I saw this particular macro get to about line 79 and then it just drops out. Again, I think I have a few issues going on here so the troubleshooting is a bit confusing. I am trying to rule some variables out.
