Many issues after upgrading to 3.0 RC-12

@TheBasedDoge Are your endstops on the Duex board?

TheBasedDoge

Everything is plugged into the Duet itself. I have no extra add on boards.

The Z-Probe modification you posted I think did the trick, it seemed to probe fine if I do homeall while manually holding down the y endstop. Still having the y issue.

PaulHew

@TheBasedDoge try homing the axis individually first. HomeX HomeY HomeZ. Homeall might need some work.
Have you posted homeall?

Maybe this is the issue. I don't know why Y says -5 but x is -305?

PaulHew

Just incase your axis is over the other side of the bed, it needs to know how far it can go. It is only a homing move, not bed dimensions!

As I mentioned. try home 1 axis at a time, please. then we can tweak homeall

TheBasedDoge

Ok for individual homes:

Homex - works fine
Homey - error, insufficient axis homed
homez - error, needs to home y.

PaulHew

without you finger on x and Y?

PaulHew

My X and Y endstops

;Endstop Configuration
M574 X1 S1 P"xstop"			             ; _RRF3
M574 Y1 S1 P"ystop"			             ; _RRF3

PaulHew

if the endstops are not engaged what does it say in
Machine specific - Endstops? in DWC

TheBasedDoge

Yeah, that is without my finger on any endstops.

But just to see what would happen, i did this.

Changed:
G1 H1 Y-5 ; home Y axis
G1 X5 Y5 F6000 ; go back a few mm
G1 H1 X-305 F300 ; move slowly to X axis endstop once more (second pass)
G1 H1 Y-5 ; then move slowly to Y axis endstop

To:
G1 H1 Y-305 ; home Y axis
G1 X5 Y5 F6000 ; go back a few mm
G1 H1 X-305 F300 ; move slowly to X axis endstop once more (second pass)
G1 H1 Y-305 ; then move slowly to Y axis endstop

now it's working! I changed it in homey also.

oh its working in machine specific - endstop also... it changes correctly based on the trigger

TheBasedDoge

Well, another problem of course. The fans are not working:

New fan code:

; Fans
M950 F0 C"Part" Q500 ; create fan 0 on pin fan0 and set its frequency
M106 P0 S0 H-1 ; set fan 0 value. Thermostatic control is turned off
M950 F1 C"Hotend" Q500 ; create fan 1 on pin fan1 and set its frequency
M106 P1 S1 H1:2 T100 ; set fan 1 value. Thermostatic control is turned on

old 2.x fan code which worked

; Fans
M106 P0 S0 I0 F500 H-1 ; Set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned off
M106 P1 S1 I0 F500 H-1 ; Set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned off
M106 P2 S1 I0 F500 H1:2 T100 ; Set fan 2 value, PWM signal inversion and frequency. Thermostatic control is turned on

PaulHew

my fans for comparison

;
M950 F2 C"fan2"						;_RRF3_ define fan2
M106 P2 H-1

TheBasedDoge

That worked for part fan, hotend fan is still not working for some reason. I also have dual extrusion. The only change i made was adding H1:2

; Fans
M950 F0 C"fan0" ;Part Cooling Fan
M106 P0 H-1
;
M950 F1 C"fan1" Q500 ;Hotend Fan

EDIT: ah nevermind, im dumb. I had the fan plugged into the fan2 the entire time

TheBasedDoge

Ok, I am making progress on getting everything working, still a few issues.

Does anyone know how I can tell the duet to home X, hit the endstop, move over 15mm and tell that to be the X home position? reason being, my endstop for X is actually too far off the bed.

https://duet3d.dozuki.com/Wiki/Gcode#Section_G92_Set_Position. So home X, move it 15mm, then use G92 X0.

You can also use a negative value for your M208 X minima such that 0 is the edge of the bed and the negative value is when the endstop is triggered.

Ok, this did the trick perfectly, now the nozzle is lined up with the corner of the bed. Thank you!

Next issue..... When I run my G29 it skips the back half of the bed entirely. I suspect I have something set wrong with the offsets or mesh config but I must not be understanding the math correctly

My bed is a 300x300. I set it to 290x290 to allow for room for it to not hit the bed clips

Phaedrux

Make sure your probe offset is correct. -X to the left, +X to the right. -Y to the front, +Y to the back.

TheBasedDoge

Ah ok, that was wrong. my probe is front right of the primary nozzle, so i changed it now to read y-5

Still having the same issue, back third of the bed will not probe
