No, I haven't,
Could you link me to that?

So I have a duet wifi and a Duex_5 Board with a Dyze-end extruder attached to that. I am getting constant heater faults during and before printing, I don't know why but any help would be much appreciated because it is very hard to print when it always stops 1/4 the way in.

Here are the last two ones i got:
2:07:27 PMError: Heating fault on heater 1, temperature rising much more slowly than the expected 1.5°C/sec

1:05:25 PMError: Heating fault on heater 1, temperature excursion exceeded 15.0°C
Resume-after-power-fail state saved
Printing paused
Cancelled printing file 0:/gcodes/SpiralVaseHD (1).gcode, print time was 1h 51m
Error: Shutting down due to un-cleared heater fault after 600 seconds

12:55:37 PMError: Heating fault on heater 1, temperature excursion exceeded 15.0°C
Resume-after-power-fail state saved
Printing paused

12:55:24 PMError: Heating fault on heater 1, temperature excursion exceeded 15.0°C
Resume-after-power-fail state saved

So what is the best way to go about fixing this?

All of a sudden all 3 fans on my printer stopped turning on when i turned the duet wifi board on. I disconnected them from the board and powered them directly with the powersource to see if they would work and they turned on with no problem. What could be the problem here?

@joergs5
So do you think it would be worth while getting a thicker print bed, so that we can do the 3 three point approach because right now it would just bend. what thickness would be good Like 1/4 In? Also what the point cause if the bending is worse with 3 point then just use another point so that its not as bad right? whats bad about the 4th point?

"The 1 mm deviation: is it at different places or just at one end? If it is at one end/side, you can set that side higher.
the way i look at it is the left side is just a little low and the right side is a high. but this could then be fixed with a thicker peice of metal and then some 3 point leveling like you said.

But if im not able to get a peice of metal right now how would i set the one side higher/lower?

@joergs5
my printer is a big custom printer i built with my brother. it has Four z axis motors and 2 Y axis motors with one x axis motor. The boards are a duet wifi and a deux 5 extender. The bed is ig metal plate that the taped down to the frame to there is not adjusting the bed.

Thanks

when i'm going through checking my trigger height throughout my print bed it is not the same throughout the bed. It can be off as much as 1 mm sometimes. I know this isn't right and how can i fix this because i think this is also leading to my problems when im printing.
Thanks

Sorry for the late response

0_1535219157439_config (2).g

0_1535219167488_homez (1).g

and the way i have it hooked up is its Positive and negative wires are hooked up to the 12v power supply because it needs at least 6 volts i think and then its other wire going to the z probe input.

@nylkos
how do i set the offset?
