ok chi fa da se fa x tre

It sounds like you're having a common problem experienced with corexy setups. I will copy and post a description of what must be done. Consider it an order of operations. It will hopefully get you on the right track. Please post if you have any questions.

https://forum.duet3d.com/topic/12676/mirrored-x-axis/9?_=1585861769573

In general, here's what you need to do to define your coordinate system. The FT5 is a little tricky because by default it puts the origin at the rear right, and has some printed grid on the bed surface (I think?) but really it's all arbitrary.

First, choose a FRONT for the printer so that when you're looking at it standing in front of it 0,0 is the front left corner, X+ goes to the right, Y+ goes to the back. This does not change because it's describing the physical layout of the printer.

Next, Measure the axis length for X and Y and enter that in your M208 command to set the axis limits. 0 at the low end (or even negative if the head leaves the bed surface to hit the endstop). This does not change because it's describing the physical layout of the printer.

Now identify where your endstops are located. They can be at the low or high end of the axis. Define them with M574. M574 X1 Y1 for low side, M574 X2 Y2 for high side, or any combo thereof. This does not change because it's describing the physical layout of the printer.

Now setup your homing movements. If the endstop is at the low end of the axis, the homing move must be negative. And vice versa. This does not change because it's describing the physical layout of the printer.

Now test the motor movement direction. If X+ moves to the right, you're good to go. If it moves left, you need to change the motor rotation for the X driver by changing the M569 S0/S1 command in config.g. Same goes for Y+ moving to the back. If you've connected the motors to their default drivers, it should be mapped like this:

M569 P0 S0 ; Drive 0 (x) goes backwards
M569 P1 S0 ; Drive 1 (y) goes backwards
M569 P2 S0 ; Drive 2 (z) goes backwards
M569 P3 S0 ; Drive 3 (e) goes backwards
If you follow those steps your printed parts will match the orientation in the slicer and won't be mirrored.

You can use these steps to test your motor movement and make changes accordingly: https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter#Section_Testing_motor_movement

@Leblond Sorry, I'm using google translate, but I don't really understand what problem you are having. I think you say your motors are moving the X and Y axes correctly, but not towards the endstops.

First, check the X and Y axis are moving in the correct direction for CoreXY. See https://duet3d.dozuki.com/Wiki/Test_axes_or_motors_individually

Once the X and Y axis move correctly, then get the endstop configuration correct. You have the endstops set in config.g at the low end, X0 Y0.

; 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

Your homeall.g moves X and Y to the minimum, by moving X-335 and Y-335 towards the endstops. Is this not correct?

It may be a good idea to draw a picture to show where everything is on your printer, like this, which will help us understand where everything is without using Google translate:

ti capisco ho problemi di comunicazione anche io, scrive cio' che pare a lui e adesso ne ho capito la causa, il problema e' che devi srivere senza la correzione del traduttore, ma attivarlo solo quando leggi, si ho risolto per fortuna il problema del sensore, riformattando la SD, e si ho il problema di movimentazione degli assi x e y, grazie per il momento @droftarts ci guardo e poi ti dico.

Leblond

@droftarts una domanda, le coppie delle fasi del motore indicate sull'immagine https://duet3d.dozuki.com/Wiki/Duet_Wiring_Diagrams : cioe' 1A+1B 2A+2B sono queste, ma se nei motori le fasi non sono corrette? che problemi puo' dare?

Phaedrux

Use this method to identify the phases: https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors#Section_Identifying_the_stepper_motor_phases

Leblond

@Phaedrux ok fatto grazie 1000

droftarts

@Leblond if the phases are wrong, The motors won’t move and you will quickly get a message that there is a problem. As your motors are moving, I think your motors are correctly wired.

Ian

Leblond

@Phaedrux ok allora le fasi sono corrette, un problema in meno
ho misurato gli assi e ho 352mm su x, e 352mm su y, si parla anche di valori negativi se la testina di stampa esce dal piatto
quindi nel comando M208 invece di X0 dovrei mettere M208 X-5 mm, perche' la testina e' fuori dal piatto di 5mm a sx come X min, e come X max dovrei mettere M208 X352 mm, perche' si parla di layout fisico giusto?

Phaedrux

That sounds correct.

asse X e Y tornano verso il finecorsa, fin qui tutto ok, ma il risultato non e' quello che mi aspettavo. "Foto in alto della dashboard"

@Leblond said in Cambio elettronica:

M574 X2 S1 P "! Xstop"; configure active-high endstop for low end on X via pin xstop
M574 Y2 S1 P "! ystop"; configure active-high endstop for low end on Y via pin ystop

X2 and Y2 mean the endstops are at the high end of travel. So when homed the axis position would be the max value.

Is the X endstop on the right side? Is the Y endstop at the back?

Leblond

no la stampante vista da "davanti", X si ferma a sx dove posizionato il finecorsa, Y si ferma davanti dove posizionato il finecorsa

Leblond

ti mando schizzo

@Leblond said in Cambio elettronica:

no the printer seen from "front", X stops on the left where the limit switch is positioned, Y stops in front where the limit switch is positioned

Ok, go back to my post above: https://forum.duet3d.com/post/142912

You've managed to change the configuration to force it to work, but it's not working properly.

If the endstops are on the low end it must be M574 X1 Y1.

This also means the homing moves must be negative.

If the motors do not move the right direction at this point you must do these tests to correct the motor rotation:
