It's a corexy so your homing file needs a slight modification to work correctly. Right now you're moving both X and Y at the same time to the endstop, and when the first one strikes, it stops both. Then you ask it to back off both, but one of them won't have been homed yet.

Try this

; homeall.g
; called to home all axes

G91  	                 ; relative positioning
;G1 H2 Z5 F6000        ; lift Z relative to current position
G1 H1 X-395 Y-345 F3000 ; move quickly to X or Y endstop and stop there (first pass)
G1 H1 X-395 ; make sure both are homed
G1 H1 Y-345
G1 X5 Y5 F1800      ; go back a few mm
G1 H1 X-10 F360 ; home again
G1 H1 Y-10        
G1 H1 Z410 F1800	; move Z up until the endstop is triggered
G92 Z410			; set Z position to axis maximum (you may want to adjust this)
G90					; absolute position

@Hugsy do not have more than one client from 1 IP address or else you will get odd behaviour with replies being consumed by one and thus not showing up in the other.

The session limit is due to memory limitations on the Duet MCU.

@M4ster_3 yes thats the change to make to test it on temp2

@MIke-1 said in Thermistor 104nt-4-r025h42g:

M308 S1 P"e5temp" Y"thermistor" T100000 B4138

sorry my cut and paste mistake. it should have been
M308 S4 P"e5temp" Y"thermistor" T100000 B4138

to replace this line
M308 S4 "P"duex.e3temp"" Y"thermistor" T100000 B4138 ; configure sensor 4 as thermistor on pin duex.e6temp

if S4 is actually connected to e3temp rather than e5temp then adjust the line accordingly.

@Hugsy thanks, and yes the diagnostics will be helpful. One thing that I note is that you have a maximum of 8 http sessions so you may be hitting that limit, M122 will let you know, although you only get 1 session per IP client address.

@e4d I notice that you have 6 out of 8 HTTP sessions in use, are you connecting to the board from multiple devices?

@djthuma please try tuning the heater again and take a screen shot of the heater tuning process. and the output when it completes.

@Design please measure 5V between these two points:

Also for the BL touch, I assume you are following these instructions:

@tkln AFAIK that approach should work for the axis - one way to find out - give it a go without the effector attached and see if the motor move as expected!

You will need a new version of the delta kinematics class for 6 axis.

@azs123 ah yes, that will be the reason, good spot.
