Again, a huge thank you. I re-assembled the hot end, it came up to temperature, I snugged things down.....ran autotune - perfect! I am in great shape! Dial in my Z height next, load material, and I am back in the game!!!

Thank you to each of you - I will look at this. Wouldn't it be great to get past this hurdle. -
RE: Volcano to Standard Nozzle: Heater Autotune Failureposted in Tuning and tweaking
The photo below shows the nozzle end, I routed the thermistor wires as far from the hot end as possible. I like where you are going, I often wondered if this is a mechanical problem but I can't see anything that hasn't worked before. I did notice the heater was a bit loose and I could move it with my finger so I tightened tightened it. I tried to heat it up and again, failure.

Volcano to Standard Nozzle: Heater Autotune Failureposted in Tuning and tweaking
PRINTER: Delta printer with Duet2 Wifi board and RepRap Firmware 3.2, Duet Wifi server version 1.25.
SITUATION: I was printing with a volcano nozzle and felt I could not tune in the Volcano to print consistently enough and decided to switch back to the standard nozzle. This was a dual configuration head so this seemed like a simple mechanical change. At the time I was running RepRap Firmware 2.05.
PROBLEM: When I autotuned the standard tip, the Autotune failed as the temperature would not come up to 205. I sent M307 H1 S205 to the controller.
THERMISTOR: Tulead NTC3950, 100K. Same as what ran with the volcano head and worked fine.
I read more and more and decided maybe the best thing was to update to the latest Firmware. I see a new heater algorithm was made in RepRap Firmware 3.2 (https://forum.duet3d.com/topic/19761/new-heater-tuning-algorithm?_=1610909943273)
Well, I get the same response from the autotune command. When I run the printer without autotuning the hotend then I get a failure which reads like "temperature is taking too long" error. Maybe I am missing something very simple??? Any ideas?
Here is my config.g heater configuration:
