Y-Axis is switching off when X-home is triggered

Hello everyone,

I am so close to get my own build 3D Printer with Repetier Host to run.
But yesterday I found the issue of the 3D printer not keeping power.
When I first reference G28 X the printer moves to the other side than it should.
When I first reference G28 Y and then G28 X the printer does the referencing of both axes but having weird outcomes anyways when i wanna print.
But as soon as the X Axis hits the X-Endstop switch (Manual)
the Y axis is loosing power with zero torque (easily moveable by hand as if theres no motor) and probably the reference as well. When I push any movement
direction its gaining power like if there has never been a problem. And --> No its NOT the (hardware) stepper driver set incorrectly!!!
What did I do wrong?

Attached you will find the configuration.h
Please help!

Thx

When you were able to print, was it mirrored?
I´m not sure about repetier behavior, but to me it seems to be the classic " wrong homing direction" and therefor "wrong endswitch connector "

My guess is, your x-axis endstop is in the max. position. You have to configure repetier accordingly.
Then of course you have to change the endswitch connector on the board to max_x_endswitch, too.

Hello,

No its not a wrong set direction. It is by purpose, so that the Nozzle (feels) behaves like it was moving, and that when i press plus that it moves minus.
My X-Axis endstop is in the minus direction.
I also checked the hardwiring again --> The hardwiring is also correct.

The question is, what is switching off the Y axis Stepper power?!

Thank you

Hello again,

Now i found out that every time the X-Axis is moved to X PLUS the motor of the Y-Axis is switched off.
No matter if referencing or moving by hand!!!
Maybe the firmware is wrongly set?!

Please help

Like how?

In your config you set

// Disables axis when it's not being used.
#define DISABLE_X 0
#define DISABLE_Y 0
#define DISABLE_Z 0
#define DISABLE_E 0

So the steppers should not power down at all. Do some process of elimination and set these to a higher value like 60 or 120 (seconds).

Endstop status:
Are your endstops acting correctly?
M119 command gives the endstop status.

Thanx for the fast answer!

But what do you mean with the values you wrote?
My motors are switched off after 300sec of inactivity that has nothing to do with the problem as i know...
The endstops work perfectly and show the right state.

It seems its an pin wrongly set in the software or the 2560 Mainchip has a defect in one line.

My X-axis sits left, Y in the back but inverted so that it feels like the Head "moves" so that if i move Y+50mm that the heatbed sled moves towards the front and not the back.
Its just that if i homed all axes as soon as the X-Axis is moved into parked position towards X+ or if i try to move X+ in any possible way the Y-Axis motor switches off!

In the attatchement you will find the newest firmware...

anyone any other suggestion...
