Thank you @mfs12
Attached is the output I get when typing file bmp2c
I followed the Ubuntu instructions 2-3 days ago, not sure about the version. What machine and OS are you running? Do you have other suggestions? It's interesting because the top part of the instructions worked. The only struggle is the splash screen part. 
$ git clone git@github.com:Duet3D/PanelDueFirmware.git
$ cd PanelDueFirmware
$ git submodule init
$ git submodule update --recursive
Hello, I was able to follow the instructions at the link below and was able to change the UserInterface.cpp file, recompile, and it worked. That all worked great.
https://github.com/Duet3D/PanelDueFirmware
Toward the bottom of the page I'm having trouble with the new splash screen part. I'm getting the attached error. I'm running Ubuntu on a Raspberry Pi 5.
Has anyone else seen this before? When I try to run the bmp2c program there is an Exec Format Error. Not sure if it has to do with the OS or compiler or format or 
something else.

Any help would be great.
@deckingman you are a legend. Yes, that was it. Switched H0 to H1 and it's working now. Thank you 
Hello, I'm getting a heater rising too slowly heater fault after about 15 seconds of trying to heat up my pellet extruder (barrel + screw weight is 6.5 lbs.) I have a few guesses on how to solve this, but I'm not 100% sure. I'm currently having the problem on a 6HC V1.02 at 48VDC, firmware 3.4.6. Output0 goes to a voltage divider and solid state relay which turns the 120VAC to the two 500 watt band heaters on/off. The thermistors are standard 100kohm and are threaded in with good contact in the barrel. This setup worked in April 2022 (firmware attached) on a 6HC V1.01 at 24VDC, Output0 (no voltage divider since it output 24VDC). I tried copying the PID parameters, but it gets the heater fault with the old parameters.
The good news is it does heat (I reset the fault a bunch of times and can get it hot). The bad news is I get the fault, which is understandable since it has such a large mass. The question is, how do I tune it? Maybe it's a GCODE thing?
I also tried the manual tuning parameter method via this link: https://docs.duet3d.com/User_manual/Connecting_hardware/Heaters_tuning
For R - temperature rose 10C in 15 seconds
For C - temperature cooled from 130C to 110C in 640 seconds (no fans)
For D - the deadtime is about 23 seconds from room temperature until the temperature really starts to rise - note the heater alarm goes off at around 15 seconds, but this is a decent approximation
Is there a way to further delay the heater fault in time? I tried the line below but still get the error after about 15 seconds

This is like like trying to get a 747 to take off vs. a piper cub. Lots of mass compared to a typical extruder.

@NeueKlasse Thank you for making this tool. I gave it a try on my windows machine. The splash screen appears plain white for about 1/2 second and I don't see the BMP image. Files are attached. Can you give it a shot and see if it works on your machine?
I'm loading this to a paneldue 7i. I'm using PanelDueFirmware-3.4.1-7.0i and splash.bmp as the input in the attached zip folder. PanelDueFirmware3.bin is the output.
@dc42 Can we please add .bmp as a valid file type for attachments in this forum? I see .bmb listed below. Maybe it's a typo. I tried uploading a .bmp file and it gave me the error below.

@fcwilt Thank you. Your wiring worked. The + fan wire went to V_OUTLC1 and the - fan wire went to OUT4. I was able to adjust the fan speed using the slider in the Duet Web Control. This was for the one with thermostatic control off. I also tried OUT5, which had thermostatic control on (while the machine was heated up), and I wasn't able to adjust the fan speed, but not a big deal. I'm very happy that you were able to help with OUT4 
I also think I fried my 12VDC fan before my original post, putting the jumper on 24VDC, which didn't help my cause.
Overall, this is great progress though, and to be able to regulate the new fan with PWM is awesome
@fcwilt Thank you. I will try this. Very interesting. Never heard of anyone pulsing the connection to ground before, but that makes sense.
Hello, I have a Duet 6HC with a 12VDC fan. I'm looking to control the fan via PWM to control the nozzle temperature. I know the wiring works because I connect the fan's negative terminal to OUT4 GND and positive terminal to OUT4 V_OUTLC1. The fan spins fine. If I change the pinout to negative terminal to OUT4 GND and positive terminal to out4 and it doesn't spin. I've also tried the same on OUT5 and OUT6. I've also tried changing the PWM Q500 to Q400, Q300, etc... I can't get the thing to spin on OUT4 , OUT5, or OUT6. Can someone please explain to me how the PWM fan control is supposed to work? How does thermostatic control work? What are the pros and cons to thermostatic control?

Thank you @alankilian
This was just my human error. I was using the normally closed contacts on the switch, (not normally open) and when I went to home Z with nothing plugged in, it instantly homed, as it should.
I simply forgot that I was using normally closed contacts. I was thinking, why isn't the Z axis moving when homing??!! Doy! It's been a while since I designed the thing. Man I feel dumb.
I'm having an issue with Z home. Will try to paint the best picture I can. If you need more info please let me know.
I've run this machine successfully for about 6 months. I'm running the 3.3 firmware on a 6HC.
When I press the home button in the web interface, the Z axis moves for a split second and homes (button turns blue). The machine thinks Z is homed, but the problem is the Z limit switch isn't even plugged in .
X and Y home fine, and I'm using normally open limit switches: https://www.amazon.com/gp/product/B08736NP44/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
Nothing is plugged in for the Z limit switch (see my picture of the board, pointing to the home switch location with a green pencil).
I was thinking it was some kind of torque limit or something, but I can move the linear stage with the X and Y drivers/cables no problem. With power off, I can turn it by hand and it seems normal.
I worked on it all morning and couldn't figure it out. Then I turned off power, ate lunch, came back half an hour later, and it worked! (for about 15 minutes). Then I kept having the same issue.
Seems like an intermittent driver issue. Has anyone had this before?
Maybe I hot swapped the motor at some point and it damaged the driver. But I don't know how that would affect the Z limit.
Files are attached. Has anyone seen this before, triggering home without anything plugged into home?
Maybe I'll buy a new 6HC and see if anything changes.
