@chris4 Difficult to know if it's 'right'! Apart from saying it's a Cartesian printer, I know very little about the machine, eg motor, belt, leadscrew, hot end, thermistors etc etc. And I have no idea if you've wired it up correctly. If you've followed through the commissioning steps here https://duet3d.dozuki.com/Wiki/Step_by_step_guide#Section_Commissioning_tests you've got a good chance everything will be fine, and it's on to test prints and tuning.
Couple of notes:
M92 X160.00 Y160.00 Z2560.00 E837.08 ; set steps per mm
With these settings, I'd guess you were using GT2 belts and 0.9º motors on X and Y. Z2560 for Z implies 1.8º motors with M8 (1.25mm pitch) leadscrews. Probably a 0.9º extruder motor.
Your other motor settings look pretty default.M574 X1 Y1 Z1 S0
Your endtops are still set 'active low'.M305 P0 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 0
M305 P1 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 1
T100000 B4138 is the default thermistor setting, for a Honeywell 135-104QAD-J01 thermistor that shipped with hot ends from RepRapPro, who have been out of business for 4 years! So I doubt you have the correct thermistor settings, and likely the temperature your heaters are reporting is not accurate. All 100k ohm thermistors have a resistance of 100k ohms at 25C, and will be fairly accurate at room temperature, but they report very differently as they get hotter. So please check what thermistors you have in your bed and hot end, and set them correctly, then you have a chance of accurately setting extrusion temperature.That's all I can see from config.g. Whether your homing gcodes are accurate is another story!

@droftarts
HI again Ian,
I forgot about switch how should I connect for this configuration we talked about last time. Should I connect pin 1 and 2 (NC-C) as outermost pins on the switch on all 3 switches. And on the duet2wifi stop end 3 pin connector (pins 1 and 3) is that right?
Thanks again -
Crash....
with new connection NC switches have crashed.
How to be LEDs on the duet2wifi card when the switch is pressed.
Mine lights up when the switches are pressed. should they be so?
I can take my settings once. left side set front view is home to my printer -X step motor to go right, must rotate backwards.
-Ystep motor to go from home position to front must rotate backward.
-Z steper motors to go up from home position must rotate forward.
All axes in the hom position, the switches are pressed.
What am I doing wrong?
Now I have this configuration.
Hope you have time with an old man.

Prior to moving a machine that's had endstop configuration changes, verify switches by pressing with your finger and looking at the "Machine Specific" tab of the Web interface. You can see their triggered status go "Yes" or "No" in real time.
The lights help you know the switch is wired, and changing. The lights to NOT tell you if the firmware considers the switch triggered or not. The web interface does that.

@Danal
Thanks.
Have a little hard to understanding how is it with Endstop Location at low end high end. How can explain this to an old man.
If we take X axis in my case, I have home 0 for printer on left seen from the front.
X step motor to go right must rotate counterclockwise (backward).
The switch is to the left of the X axis, and connected to the NC.
How about the endstop which should i choose, low end or high end.
has drawn a sketch of it.

If moving the axis to bigger (positive) numbers makes it go toward the switch, the switch is at the high end.
If moving the axis to smaller (negative) numbers makes it go toward the switch, the switch is at the low end.
To keep from crashing things, do a very small move. This is easiest to do in relative mode, for example (you can enter these one at a time on the console):
M564 H0 G91 G1 F1000 X-10The M564 allows movement without homing. The G91 is relative mode, and the G1 will move X 10 mm. Since it is negative, if X moves toward the homing switch, that switch is at the low end.

On the left or right of the shaft (0 home is on the left together with the switch and the stepper motor is going from left to right on the Xaxel to move the extruder carriage)
One question, stepmotor motion is against the switch or vice versa when setting stepmotor motion to in drivers.
very complicated for me. Must learn more about this. -
You've asked about everything EXCEPT the numeric value that moves X. And that value is THE determinant. Yes, it seems complex if you bring in left, right, counterclockwise. But... none of that matters. Push it out of your mind. Make it simple.
Does
M564 H0 G91 G1 F1000 X-10move the carriage TOWARD the switch? If so, that is the low end. Period. Nothing else enters into it. You can enter all three commands on one line exactly as shown. Please do that and report whether it moves toward the switch.P.S. The "negative moves toward = low" is exactly what @deckingman said in the third post in this thread.

Thanks so much for the explanation.
G code M564 H0 G91 G1 F1000 X-10, nothing happens but if you do X positive, 10 moved to the right.
With a little more experiment , maybe I understand how it works.
but thanks for the help- -

The first part of -10 nothting happens is expected ; unless you set x > 0 or allow it to move outside the axis minima it will not move below 0.
The second part is correct, +10 should move to the right in a Cartesian coordinate system. The last part of the puzzle is to determine if the switch is on the far left (M574 X1) or far right (M574 X2).

and now works properly with home all.
step motor goes towards the switch on the left press and x step motor stops. I continue with the calibration now, it will be a challenge for a senior, who is a bit sluggish.

is that a question for y?
if you have a printer like in the pictures where the bed moves, the confusing part may be that you're not interested in the movement of the bed, but rather the position of the nozzle on the bed. so a positive Y movement should move the bed towards the front, but the nozzles relative position would be towards the back of the bed.
so the y switch at the back of the printer would trigger when the nozzle is at the front of the bed, meaning low end.
(i.e. its the nozzle and coordinate system that determine motor direction, and then you set the end stop location after the motor direction is having the desired effect on the nozzle position)
-
That explains some of what I couldn't. Thanks

Fantastic! Combining these two answers, the negative move moved TOWARD the switch. That means the switch is on the LOW END.
That means your M574 for this switch should specify X1 S1
Yay! Progress!
