PanelDue and Motors will not function properly with Duet Wifi

M574 Y2 S1 P"ystop"

I’m not quite sure, it’s a complicated thread, but if your endstop for Y is at the front of your printer and if you want the X/Y origin to be in the front left corner, I think you must change the last line to

M574 Y1 S1

because - if I’m right - the Y-endstop sits at the low end.

Double checked to try that, and it'll set it to 0, 0, 0. But any +Y command will keep it going towards the front of the frame.

I guess I want to mirror the Y while also keeping 0 at the corner, but instead of moving forward for +Y it'll go back.
Make sense?

infiniteloop

@firex726 That makes sense, if you want to have the origin of the X/Y coordinate system to be front/left.

– Just to be clear: at this point in space and time, your end stops and your min./max. settings are perfect. Don’t touch these lines again. –

Now, the question is how to change the direction of a single axis on a coreXY: honestly, I don’t know. With my cartesian, it’s simple, but here, either you know what to do, or one of the coreXY experts has to chime in.

Last, you will likely have to adjust your homeXY moves - possibly to a negative Y value.

Tried that too... Sadly the issue is just when it's home. If I just move it around manually it'll be OK.

The motors and endstops seem to be OK based off the linked articles; it's just logically it think's it's mirrored once it hits home.

I think it was noted earlier that the firmware is expecting a Right hand build, but I have a Left hand one, so one axis will be flipped.

I noticed that. What I do not understand is this:

You mean that before homing, positive Y values move the head to the back of the printer?

Sadly no... Whichever is mirrored will move in the opposite direction. But due to the design of the mount it's easier to deal with on the Y.

I think I may just rebuild it to how the firmware thinks it's designed. I had assumed there would just be a simple setting I could flip to mirror whatever axis I want.

Alright, let's take one more shot at this.

Please post your current config.g and homing files.

Also please confirm where your Y endstop is located. Your photo shows X but not Y. From previous descriptions it sounds like it's located at the front as labeled on your last photo?

There are such settings. Any function of this whole setup can be flipped with a single change to config.g.

The issue is: Endstops at which end of the machine vs. travel direction vs. homing with + or - numbers in the homing files. They all have to match each other. And the VERY first thing that has to work is CoreXY movement.

Work through ONE of these at a time, and it can all be figured out.

Since we can't see your printer, nor exact results of various commands, it is very difficult to remote support (btw, I'm just a customer) unless we get so very meticulous in our terminology and photos and etc that everyone gets impatient... and then there is an ever so slight miscommunication and the whole 9 way (3 axis, 3 things to get aligned with each other) thing becomes confusing again.

Which is a really long winded way of saying: Work slowly, first movement (NO HOME), then endstops (still no home), then home to endstops and you will actually be able to figure this out faster on your own than all the interaction on the forum here.

We will all still try to help (I've been in workshops all day, so I didn't post much earlier today)... at the same time, the "do not attempt the next thing until the first thing works" approach can iron this out in minutes.

Hi there,

Here ya go... I figured I'd start with fresh config files, and a new photo for us to base things on. The labels are for where I intend the machine to think each set of coordinates is at.

Ok that photo looks good. Looks like the Y endstop is at the front now for Y min.

Just noticed your drive mappings are pretty... non-standard

M584 X3 Y4 Z2 E1 ; set drive mapping

Don't think it really matters here, but wondering if there's rhyme to the reason? Are we dealing with a blown driver or something?

Typically they'd be connected like so:
M584 X0 Y1 Z2:3 E4:5:6 ; Driver 0 controls the X motor, 1 controls Y, 2 and 3 control Z motors, 4 5 and 6 control E motors

Axis limits and endstops look correct.

; Axis Limits
M208 X0 Y0 Z0 S1                               ; set axis minima
M208 X280 Y280 Z280 S0                         ; set axis maxima

; Endstops
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"                            ; configure active-high endstop for low end on Z via pin zstop

Your homing moves look correct.

; homeall.g
G91                    ; relative positioning
G1 H2 Z5 F600          ; lift Z relative to current position
G1 H1 X-285 Y-285 F600 ; move quickly to X or Y endstop and stop there (first pass)
G1 H1 X-285            ; home X axis
G1 H1 Y-285            ; home Y axis
G1 X5 Y5 F600          ; go back a few mm
G1 H1 X-285 F180       ; move slowly to X axis endstop once more (second pass)
G1 H1 Y-285            ; then move slowly to Y axis endstop
G1 H1 Z-285 F180       ; move Z down stopping at the endstop
G90                    ; absolute positioning
G92 Z0                 ; set Z position to axis minimum (you may want to adjust this)

The next thing to nail down is the direction of rotation for the X/Y motors.

; Drives
M569 P3 S1                                     ; physical drive 3 goes forwards
M569 P4 S1                                     ; physical drive 4 goes forwards
M569 P2 S0                                     ; physical drive 2 goes backwards
M569 P1 S1                                     ; physical drive 1 goes forwards

Now in your setup P3 and P4 would be X and Y. This is where we'd do the G91 G1 H2 X10 and G91 G1 H2 Y10 moves and go from there.

https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter#Section_Testing_motor_movement

The testing begins with the assumption that we'd be using M569 P3 S0 and M569 P4 S0 so change those to S0 and do the movement test.

Phaedrux

This would also be a good time to test the endstops before even testing homing just to ensure they are configured corrected. If you trip them manually do they show as triggered in the machine status view?

Danal

Curious where the X endstop is, physically?

Phaedrux

I believe it's on the printhead on the HEVO. You can see the Red green black wires for the optical endstop running to it. The flag is on the left X gantry block.

Hi All,

Carriage is in the center, normally 140, 140...

G91 G1 H2 X10

Moves diagonal towards 0, 280.

G91 G1 H2 Y10

Moves diagonal towards 0, 0.

M569 P3 S0
M569 P4 S0
G91 G1 H2 X10

Moves diagonal towards 280, 0.

G91 G1 H2 X10

Moves diagonal towards 280, 280.

If you trip them manually do they show as triggered in the machine status view?

Correct, which is also why the homing speed is so slow, to give my hand time.

Just noticed your drive mappings are pretty... non-standard

Yes, earlier when having issues with only one motor moving it ended up being the diver was blown.

you can test the switches without moving the motors, just press and hold a switch while you run M119 release switch and run M119again to confirm both states. repeat for each axis

jay_s_uk

@firex726 Or use the machine specific settings page in DWC to watch the endstops while triggering them, rather than running M119
