Heater Woes and headaches

Heater Error problems and confusion.
Howdy again, I've got the replacement smart effector and its working well now so that is a good thing. But even as before I cannot for the life of me to get the hot end heater working. I'm on a 12v power supply. I've tried new thermistor and a new premium E3d heater cartridge 12v 30w and re wired the 6 molex plug again and it still shows that I'm heating up too slow. I've tried both E0 and E1 plugs in the main duet wifi board and it still shows the error. I've tried the following as well:11:32:14 AM
Auto tune cancelled because temperature is not increasing
11:31:37 AM
Auto tune phase 1, heater on
11:31:32 AM
M303 H1 S240
Auto tuning heater 1 using target temperature 240.0°C and PWM 1.00 - do not leave printer unattended
11:31:02 AM
M307 H0 D30
11:28:08 AM
Auto tune cancelled because temperature is not increasing
11:27:31 AM
Auto tune phase 1, heater on
11:27:26 AM
M303 H1 S240

M307 H#
Heater 0 model: gain 90.0, time constant 700.0, dead time 10.0, max PWM 1.00, calibration voltage 0.0, mode bang-bang, inverted no, frequency default.My config file is here. I'm running the newest firmware. I do see the light try and come on with the board but then shuts off when I get the error.

Thanks for looking and any help is awesome.

And here is my H1 values
M307 H1
Heater 1 model: gain 340.0, time constant 140.0, dead time 5.5, max PWM 1.00, calibration voltage 0.0, mode PID, inverted no, frequency default
Computed PID parameters for setpoint change: P13.4, I0.482, D51.4
Computed PID parameters for load change: P13.4 -
I suggest you disconnect the extruder heater wires from the Duet and use a multimeter to measure the resistance between them. You should be able to measure the cartridge resistance as listed here https://e3d-online.dozuki.com/Guide/V6+Assembly/6?lang=en#s70. If instead there is no continuity between the wires, use your multimeter to pin down the broken connection.

Ok can I assume that I can test from the duet board 1st from the bottom of the board (below the terminal block) on the + and - that I should get a complete circuit? (sorry about the basic question.) If I don't and the wires show a complete circuit could I have a problem with my connection with the block?
Thank again soo much,

What I meant was that you can disconnect the heater wires form the Duet E0 heater terminal block, then measure the resistance between the wires. But as long as the power is off, you should also get the right reading if you leave the wires connected and measure the resistance between them either on the back of the Duet or between the two screws in the terminal block.

Ok we are heating, after some probing the soldering job on the duet board was poor on the terminal block, on the negative side of E0. I'm now heating the end and onto some other calibration stuff. (At least my wiring was ok, so I'm not super down on myself;)
Thanks sooo much for all of your help, because without it my delta would of been sold by now. My hope now is to get a print and go from there.
You guys are awesome.

I'm sorry to hear that the soldering on your Duet was sub-standard. Is it a genuine UK-manufactured one?
-
I'm assuming yes since I got it from Filastruder, I wanted to keep the $$ with the folks that helped developed it and not a cheap clone.
Again much thanks,

Bill, thanks for your support!
