hello, i have a I3 PRO B
since today I have a problem of displacement in X and Y. (without changing anything, before everything worked correctly) when I request a displacement of 1mm in X and Y, they move 60mm. I change the step / min but it does not change anything. always 60mm, even if I request a movement of 1mm or 50mm.

Hello.
Have you tried to take the stepstick modules out of the sockets and insert them again

On the forum I help to use the rod, I don't give fish.

Re: problem movement
yes of course, I also tried to reverse them
Re: problem movement
Hi
And is it possible to control movements in two directions?
e.g. forward and backward or right and left?

Re: problem movement
Hi.
If the extruder is working properly, stepper motor control modules can be replaced for the test.
If you gave a more descriptive answer, it would be easier for me to imagine your situation.

Re: problem movement
Okay.
the 3d printer was working properly. I relaunched an impression because the Zoffset was too high.
the printer is going to touch the XYZ min. then, instead of placing the extruder in the middle of the board, XY went beyond the board in XY max. the printer goes into safety.
so i try to restart the 3d printer.
I ask for a Home. the printer makes XYZ min correctly. then, when I request a displacement of 0.1mm, the displacement is 50mm the first time (in X and Y). then the movements are done correctly on the remaining part of the board.
I controlled the marlin configuration, I reinjected it several times. I reinjected the marlin stock. I try to change the step / mm engine, but it does not change anything.
I changed the polulu drivers. But it does not change anything.
I looked at the motherboard. Q4 is burnt ... which is strange, it seems that Q4 is part of the USB POWER. it has nothing to do with the problem?

Re: problem movement
Now very clearly.
I will start from the end.
The solution you are talking about I found in the version of the GT2560 rev A+ controller board.

I would unsolder him even if he wasn't broken.
Though broken, he is not sure either. We don't really know how he behaves.
Now I can see that the problem only occurs in a certain situation.
So most probably electronics should be working.
Try to save the current configuration in the controller's memory using the operator panel.
Turn the printer off, after a while and check the settings. They should be identical.
If you are 101% sure that the Marlin software configuration was done correctly and it should work, however, it may prove that the controller board is very specifically damaged.
A user with the same printer model in the same configuration would be helpful.
The dysfunction appears to be troublesome to diagnose remotely.

Re: problem movement
ok, I have to despair Q4 and .. it does not change absolutely anything ...
however, I just realized:
when I turn ON the printer, I make an "auto home" ... XYZ min movement are correct then, the LCD shows me: x = -95.5 and y = -112.5
I do not know why.
so it makes sense, the slightest movement the printer wants to be in 0 on X and Y ....
but if on the command of the LCD screen, I click on "set home offset": I have a beep, the screen indicates X = 0 and Y = 0; and if I start again an "auto home" the values are put well on X = 0 and Y = 0. and displacements become correct again
so I do not understand ..
