I come through this post, rescue a problem with my printer. It uses Arduino 2560 Mega, RAMPS 1.4, and Marlin 1.1.9, which had configured it left it working as follows: on the RAMPS the Y-axis is connected to the Z-axis pins, as it has two stepper motors on the Y-axis and the Z-axis is connected to the pins of E1.
I did all the basic and necessary configurations in the firmware and sent it to the Arduino, eliminating the previous configuration, so that I can configure the steps of the motor correctly, as they were out of calibration. Before the reset, the motors moved to both sides, positive and negative. However, when I sent the firmware to the Arduino, I can only rotate the motors on all axes only to one side.
On the printer display, I go to the option to move the axis, rotate it 10 mm and the axis moves. However when I move it backwards, it does not come back, it is stopped. This happens with all the axes after I did the reset. Is there any way to configure the rotation of the motors by the firmware in relation to pins A1, A2, B1, and B2 in the same way that the axis change on the RAMPS was configured?
I apologize for the mistakes, I speak Portuguese and I used a translator.
I executed the command
M119 on the console of the Marlin IDE and the printer did nothing, it is correctly connected to the PC via the USB cable
this appeared on the console screen:
x_min: TRIGGERED y_min: TRIGGERED z_min: open ok
