Can't Flashing Octopus V1.1 via DFU during initial setup.
Yep. That's exactly what I had to do with mine as well. Seems RatOS likes to see an image on their first.

BedMesh both COLD & HOT show too great of range tolerance?
Agreed. I only need to swap out the therm with a short lead, so existing long wire looms right to therm port.

I have both Platinum RTD PT100 & RTD 1000 therms ready to swap out. The PT1000 says it gives higher accuracy but the warning in the bag said make sure you do not need an amplifier circuit first, to prevent a fire!

BedMesh both COLD & HOT show too great of range tolerance?
Ok Hot end heater is def E3D: Says E3D 24V 30 watt, thermistor, no such luck, no codes or lettering. I pulled some new E3D hotend kits I had out and checked the thermistor values against the one I just pulled off the hotend on the printer: both read approx 100-100.5k at room temp (72f). Going to replace the therm out with a another new one anyway; something seems strange here.

BedMesh both COLD & HOT show too great of range tolerance?
Hmmm. No idea It is whatever shipped with the RatRig VCore 3 kit back when I got it. It came with the E3D hotend and BMG extruder if that helps. I will pull it apart as soon as the hotend cools a bit more. It DEF gets very hot!

Yes sir, coming your way. BTW- I'm looking at a DevilForge -one of my good friends is a Norwegian Viking and he makes CRAZY stuff like Japanese steel and Damascus steel pointy stuff. ; )

Hmmm....now that you mention it...I think the setup chose it for me. After looking at the Hotend section in RatOS, this is what I have: # WARNING. DO NOT EDIT THIS FILE.
To override settings from this file, you can copy and paste the relevant
sections into your printer.cfg and change it there.

BedMesh both COLD & HOT show too great of range tolerance?
FYI I had hotend set at 245c for PETG and that should be enough to melt and flow PETG...

BedMesh both COLD & HOT show too great of range tolerance?
No, That I cannot do. It seems to take a lot of force. I did pull apart the whole extruder assembly, checked that all out, removed the hot end and checked for blockage there. A little bit of melted filament (PETG) in the nozzle end , cleaned that out, replaced with brand new .04 nozzle ... same result. To me, it seems the extruder is not pushing the filament through and it's melting the filament but just sitting in the nozzle. Extruder works manually and without the hotend attached. I checked to make sure tension knob was not too tight or loose on extruder. I suspect undervoltage on extruder.

BedMesh both COLD & HOT show too great of range tolerance?
Yes and yes. Extruder direction is correct and spins correctly. Again, this ALL worked on the last board, for the short life span of 15 mins, until the stepper drivers overheated on the MCU. My debug.zip I previously uploaded with printer.cfg shows the correct hotend (E3DV6) and extruder (BMG). Only thing that has changed since last use was the new MCU and Klipper/RatOS.

BedMesh both COLD & HOT show too great of range tolerance?
And now I face yet another hardware challenge: My extruder & Hotend which previously worked just fine. no longer function under RATOS? I still have the test prints I did when the Duet 3 Mini 5+ was in my RatRig VCore 3, so I KNOW they work. That to me means: Voltage issue on the extruder, since the hot end heats and cools as it should...but the extruder cannot push out the melted filament. What should the voltage setting be on an E3D V6 hotend w/ BMG extruder? I looked around but cannot find a solid answer as to what the voltage should be reading. The extruder sounds like it is skipping or grinding to me.

I thought the acceptable tolerance was .2 and I'm showing .299 which is approx 33% over tolerance?

Swapped out BL Touch for RatRig 5V Induction Probe
UPDATE: Woot! It lives! After swapping out the MCU for the backup unit, printer is ALIVE and kicking. Now to start calibrations, etc. Steppers are bit noisy in idle, will have to figure that out too. Go ahead and mark this thread as SOLVED, due to defective probe port on first MCU. FYI- I also remounted the BLTouch and it is working...FIRST TRY.

Swapped out BL Touch for RatRig 5V Induction Probe
I will need to RMA this other board, as it has had nothing but problems from day 1. Oh, and I stand corrected on my backup board- it is only a BTT Octopus v1.1 (NOT Pro 1.1) . The chipset is also slower- a 446 instead of the 723 I had on the first board. Since this board IS older and a known piece of hardware...any peculiar issues I need to be aware of? There is the issue of the heaters being turned on, saw that. Also the reason I bought the 723 Pro 1.1 in the first place. Whom can I contact here for the fastest RMA? I know Luke's name was mentioned, but I don't know who that is.

Swapped out BL Touch for RatRig 5V Induction Probe
I just happen to have another brand new Octopus Pro 1.1 I just bought 2 weeks ago from RatRig. I'm not a big fan of SPOF (Single Point Of Failure), hence I always buy more than one of everything. My backups have backups.

Swapped out BL Touch for RatRig 5V Induction Probe
I'm getting leery of this board now that things are pointing back to the board. 2 Brand new probes right out of the package to me spells trouble with that probe port. Also, WHY the formerly working BLTouch wasn't working when plugged into same port. I did post quite a bit already about the weak opto coupler circuit that this port uses. Some say you need to use a different pin I/O, others say to boost the input voltage to the probe. Going to pissed if this board is FUBAR because of the probe port.
