Y Axis Zero at wrong end
-
Dear all
I have troubles to setup my Duet3D WiFi correctly.
I'm on Firmware 2.02(RTOS) (2018-12-24b1)The problem is, that the Y Axis is moving in the wrong direction.
When looking towards the printer, then Y0 is away from me. Therefore a G1 Y200 shifts the bed away from me.Y Endstop is at the Y+ side
Y Motor is at the Y+ sideAlso all printed parts are mirrored in the Y direction.
I've played already around with reversing the motor wiring and with the M586 and with the homeall.g file as well but none of them (or combination worked).
X-Axis and Z-Axis are working normal.Have spend already many hours to figure out what's wrong but without look. Therefore reaching out to you for help.
I've made a drawing for better clarification and also attached my configuration files and homing files.

In the picture you posted, if the bed is moving in toward you, then isn't the nozzle moving in +Y direction relative to the bed/part, correct? Assuming since the bed moves then the nozzle is not moving in Y direction. A G1 Y200 should move the bed towards you on most standard bed-moving printers (prusa i3 style, etc).
If this is the case then you need to change your motor direction (M569), endstop direction, and homing macro files.
But I could be looking at the picture wrong.

Dear @nhof
Many thanks for your quick reply. I'm sorry to post my answer not sooner due to lot of work and also illnes unfortunately.
I owe you something. You saved me hours of try and error. You were exactly right.But I could be looking at the picture wrong.
May i ask you, What was unclear about the picture?
In the picture you posted, if the bed is moving in toward you, then isn't the nozzle moving in +Y direction relative to the bed/part, correct?
Thats correct
If this is the case then you need to change your motor direction (M569), endstop direction, and homing macro files.
That solved my Problem. Thank you so much!
A general question:
In the duet wiki M574 --> Set endstop configuration
The parameter S is described as: "Snnn Endstop type: 0 = active low endstop input, 1 = active high endstop input, 2 = Z probe, 3 = motor load detection".Therefore I'm confused. What exactly is the S parameter?
Is it the the position at which side the endstop is positioned. At the low or at the high side of the Axis?
Or is it rather a direction?I've uploaded also a picture of the current setup with the endstop marked with purple arrows and the corresponding parameter below.
This combination worked.!My config.g file looks as follows now (working version):
M569 P0 S0 ; X Achse / S0 = Rückwärts S1 = Vorwärts M569 P1 S0 ; Y Achse / S0 = Rückwärts S1 = Vorwärts M569 P2 S1 ; Z Achse / S0 = Rückwärts S1 = Vorwärts M569 P3 S1 ; Extruder E0 / S0 = Rückwärts S1 = Vorwärts M574 X1 Y1 S1 ; End Stop // 0 = Kein, 1 = Low-End, 2 = High-End M574 Z1 S2 ; BL-Touch -

Therefore I'm confused. What exactly is the S parameter?
Is it the the position at which side the endstop is positioned. At the low or at the high side of the Axis?The S parameter defines the switch type, as in Normally Open, Normally Closed, etc.
The position of the endstop is defined by the number after the Axis letter. So X1 means the X endstop is at the low end of travel. Y2 means the Y axis endstop is at the high end of travel.
