Incorrect behaviour

LeviaChan

This is my first post, sorry for the formatting and thanks for reading in advance.

I am using a duet 2 wifi with the latest version of firmware(Release 3.3 beta 3)

List of problem:

When X home is enforced, the x axis moved a few unit to the right and assumed itself as homed, end stop were not triggered(if the end stop is triggered manually it turns off the led on the board)
When Y home is enforced, the y axis move towards the end stop correctly, hitting the end stop and keep hitting the end stop, the end stop seems triggered( based on the LED turning off on the board) but it doesn't register
The part cooling fan (fan0) are not moving when set to any percentage in the web control interface

Here is the config.g content:

@leviachan what kind of endstop are you using? Just a switch?
Eventually you need to define the pull-up or invert them...
like my setup:

M574 X1 S1 P"!xstop"                                ; configure active-high endstop for low end on X via pin !xstop
M574 Y1 S1 P"!ystop"                                ; configure active-high endstop for low end on Y via pin !ystop
M574 Z1 S1 P"!zstop"

LeviaChan

@cosmowave they are some generic microswitch from a ender 3, sorry for not mentioning those

cosmowave

@leviachan what is reportet when you send M119 ? Try with and without pressed x-endstop

LeviaChan

@cosmowave it shows:
"M119
Endstops - X: at min stop, Y: not stopped, Z: no endstop, Z probe: not stopped"

physical status: X end stop not triggered, Y end stop triggered

cosmowave

@leviachan i think, you should inverting the endstops with the "!"

M574 X1 S1 P"!xstop" 
M574 Y1 S1 P"!ystop"

LeviaChan

After changing P"xstop" to P"!xstop" the x axis now correctly bump into the endstop; however the end stop trigger was ignored, which is the same as the Y axis

cosmowave

@leviachan what is in your homing macros? homeall.g, homex.g

@leviachan try once again with m119, what's reported when endstops activated?

LeviaChan

@cosmowave

"m119
Endstops - X: not stopped, Y: not stopped, Z: no endstop, Z probe: not stopped"

Physical status:
X axis is at home position, led on the board is off
Y axis is at home position, led on the board is off

cosmowave

@leviachan try with pull-up "^"

M574 X1 S1 P"^!xstop" 
M574 Y1 S1 P"^!ystop"

LeviaChan

I have realized something intresting:
I have switched around the X and Y endstop, changing the P"!ystop" back to P"ystop" and now the Y axis homes correctly

This is weird because my endstops are ladled and plugged in the board according to the official pinout(X->Y->Z)

I have applied the same kind of change in the X axis, unfortunately it went back to the old behaviour of moving a bit to the right and called itself homed

cosmowave

@leviachan but your axles are moving properly? when you make a move x-, then the x axle is moving towards the x endstop? and vice versa

LeviaChan

@cosmowave I have found out that I am dumb and plugged the endstop into the wrong place I am thankful for your help, the X and Y axis is homing correctly now

The Z axis is refusing to home now, I will spend some time trying to fix that and post back if it goes weird again

again, thanks very much for the help

cosmowave

@leviachan eventually you have a similiar problem with the fan. Is it connected correct? And is the jumper for VFan setted properly?

LeviaChan

@cosmowave I have went back and checked, the polarity is flipped by the manufacturer, after quickly flipping the position of red and black wire it now works as intended
