extruder jams

@RRinOz your fan config looks correct.
what I would say is that your thermistor config is more than likely wrong so you probably aren't setting the temperature that you think you are.
do you know what thermistors you do have? did they come as part of a kit or did you purchase them separately? -
@jay_s_uk You are spot on. I self sourced all the parts and not knowing which hot-end thermistor I needed, I ordered two from Slice. One had white braided insulation, one had black. I still have the black thermistor in its packet. It is labeled 'RTD Pt1000' so the one I've used is likely the Pt100. I pulled out my temperature gun and measured much lower temperatures than expected through the front of the print head with fan1 removed. The gun however has a conical detection area and is probably unreliable in this application. It reads the temperature of my soldering iron correctly. I will repeat the thermistor calibration. Thank you for your interest. Regards, RR

@RRinOz If you've got a PT1000, I would go with that and change your configuration accordingly
-
@jay_s_uk Footnote: In case I have misinformed you, I have just located the packet that the 'white' thermistor arrived in. The label describes it as a 'Thermistor 300 C'. I will take your advice and change over to the Pt1000. Thanks again.

@RRinOz Post Script: I changed the hot-end thermistor to a Pt1000, reran the PID tuning and performed the Extruder E steps per mm calibration. All worked beautifully. Knowing all that can go wrong, it's a tribute to the Voron team that it (finally) works so well. The only problem now for me to address is that the y axis of the DWC Temperature Chart has changed to an unusable 2000 degrees. The only change I made was the config.g description of the Heater 0 M308 command. Thanks again for your assistance. RR

@RRinOz does it go to 2000 even with a reboot?

Is it actually reading 2000c? This may indicate a temp fault.
Is it actually a Pt1000?
What DWC and firmware versions?

@RRinOz I'm fairly sure that the scaling factor used by DWC for the temperature graph comes from the maximum temperature set by M143. So check you configuration files (including config-override.g if you use that) for any spurious looking M143 commands. Also, try refreshing your browser.

@deckingman Sorry, I started a fresh subject since the extruder jam problem is fixed. I have been told to continue the DWC Temperature Chart scaling problem in this thread.
I have fixed the scaling problem. This thread may now be closed.
I am using a thermistor on the toolhead board to control the fume extractor fan at the rear of the printer.
I have been using three micro SD cards while trying G code changes to my homing sub-routines. One of them contained an omission in the config file. As soon as I added T100000 B4138 parameters to the "thermistor" in the M308 command, the Temperature Chart rescaled to 280 degrees.
Thank you all for your interest. -
