OK so now I get it to home and move down 5mm and home again, but it then should move down and centre. but it stays with end stops activated and I get message Error: G0/G1: target position not reachable from current position

I just checked and I have
M574 X2 Y2 Z2 S1 ; set active high endstops

Wiki says they have to be seperate lines

Correct.

Dave Parry

Seem to think that error message is related to homed height, but just tried adding 5mm to homed height no different and then tried subtracting 5mm same.

Replace that G1 Z-5 with G1 H2 X-5 Y-5 Z-5 - that should do it.

It homes ok but I still get
G28
Error: G0/G1: target position not reachable from current position

Even with that change I suggested?

Curious.

sorted that out Frederick, the default end stop setting says
active high endstop switch but X1 is low end it needs to be X2

Dave Parry

Just need to sort fan control not showing and M106 not doing anything either. Think it's because they havent been properly configured.

Need to see you most recent fan code. It may be still back at v2 syntax.

Think your right

; Fans
M106 P0 S0 I0 F500 H-1 C"Part Clg" ; set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned off
M106 P1 S0 I0 F500 H-1 C"Bed Clg" ; set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned off

Yes - that's v2 syntax.

Here is my code for two fans:

; ****************************************************************************************************
; cooling fans
; -- P# is fan, S# is speed (0 to 255 or 0.0 to 1.0) H# means turn on fan when heater H# temp hits T#
; -- H-1 means no thermostatic control
; ****************************************************************************************************

M950 F0 C"fan0" Q500        ; create fan (F), pin name (C), frequency (Q)
M106 P0 C"Part" S0 H-1      ; set fan (P), name (C), speed (S), thermostatic control off (H)

M950 F1 C"fan1" Q500        ; create fan (F), pin name (C), frequency (Q)
M106 P1 C"Hotend" S1 H1 T45 ; set fan (P), name (C), speed (S), thermostatic control on (H & T)

Have got them working with this

M950 F0 C"fan0"
M950 F1 C"fan1"
M106 P0 S0 I0 F500 H-1 C"Part Clg" ; set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned off
M106 P1 S0 I0 F500 H-1 C"Bed Clg"

But have tool fan on there as well which also starts part fan

Dave Parry

Tried rem ing out fan0 but then tool fan controls do nothing

Dave Parry

Just noticed that the tool fan shows when the hot end is active and when hot end is off or standby is hidden.
I either need to hide it completely or get rid of the part fan control but have the tool fan control that fan

That tool fan display is controlled by the DWC.

It's just a way of having a single consistently named control in those cases where you might have multiple tools each with their own fan.

You can control the visibility of the actual part fan from the DWC.

Frederick,
Can you tell me where the conrol for fan visibilty is, because I cant see it.
also Thanks for your great patience and help.

Dave Parry

Found it. I was looking on the dashboard and its on the status.

This is visible when you have selected the Job/Status display in the DWC.

See the item "Change Visibility"?

Yours looks different to mine. I dont have no fans option, just lists all the fans with a tick box for each. Also jobs and status are seperate tags.

Status is under the Job category - that what I meant by Job/Status
