This stuff will help a lot:

Costs next to nothing but will save you all the headaches especially when layer fans turn on.

I'd advise it on a volcano style block.

@Texzin:

The Folger Tech FT-5 has 2z , 2y, 1x. So if I just use the Duetwifi with out the Duex2/5 I will have to connect the Y steppers in series. Can I series the Y steppers without causing problems or should I add the Duex2/5?
Can the E1 be mapped to run second y steppers?

My config above is for a FT5 Z is on the Z port (both connectors).

Heres what I use

M584 X0 Y1:4 Z2 E3                             ; Map to specific drives

M569 P0 S0                                     ; Drive 0 - X
M569 P1 S0                                     ; Drive 1 - Y
M569 P2 S1                                     ; Drive 2 - Z
M569 P3 S0                                     ; Drive 3 - E0
M569 P4 S1                                     ; Drive 4 - Y

Is U showing as in unhomed?

If you do G92 U0 and then try to mesh level does it work?

Here's what i use for reference:

M143 H0 S110                                      ; Set maximum temperature for bed to 110C
M143 H1 S285                                      ; Set maximum temperature for hotend to 285C

What's the contents of homez.g ?

My fault I was thinking of a different kind of setup!

M558 should be P5 not P1

@HenrikM:

That wiring is correct.
My bltouch is working perfect and i tried a extreme bed compensation with 1.5 mm high on one side and 1.5 mm low on other side and i got a Perfect first layer

BUT is there a code or something so you can "fade" out the compensation. that compensation makes the Z move around and can make ugly prints.

I had that on marlin with my mks board. 3mm was the compensation Then it dont compensate anymore and the print is level.
I have not tried that gcode that fades out in Marlin on my Duet. And i am not on my computer now so i cant see what that gcode is.

Sure is M376 http://reprap.org/wiki/G-code#M376:_Set_bed_compensation_taper

@dc42:

Perhaps the ground should be connected to pin 2 of the expansion connector? I don't have a BLtouch, so perhaps someone else can confirm this.

Correct.
