when I move X axis manual, Y axis moves with it!!

hello


I am totally new to the world of 3d printers. I have ramps 1.4 and I have marlin firmware.

my first 3d printer is something called "e-waste" 3d printer, it is based on steppers gotten from old CD-roms and floppy.

as kind of testing the concept, I made connections for only 2 motors with ramps X axis and Y axis. I tested that my connection is working fine when by testing them by ramps1.4 test code. I saw my motors go back and forward .
in marlin code, I disables Z axis and extruder, I disabled also the thermistor.

now the problem : I have not connected endstops yet. I connected the board now with repentier, and when I move X axis from manual control, i find Y moves with it!! and vice versa, and some times Y moves instead of X and vice versa!! I do not understand what i going on. do this has a relation with not connecting endstops??

Are you sure the firmware isn't configured for a coreXY printer? in the configuration.h file "#define COREXY" needs to be commented out

thanks for reply, I checked, and Corexy is already commented.... so I do not know what is the cause of this problem

Hi
It would really help if you could attach the marlin files configuration.h and configuration_adv.h, and a picture of the motor wiring to the ramps board.
That way it will be a lot easier to troubleshoot it.
Can you describe more in detail how you manually moved the axis?
like step by step menu selection on the 3D-printer.

Hope we can solve this

thank you very much for your help. yes I will say what I am doing.


I use pronterface or repetier , and I use manual mode. when I try to move x with step 1 or 10 or whatever, I find that x and y moves, sometimes x only, sometimes y only, same thing with y. I do not understand what is wrong exactly.

Attached to the post the configuration.h and configuration_adv.h. also attached photos to the board.

thanks for help

You are using configuration files for a DELTA printer:

...
// Define this to set a custom name for your generic Mendel,
#define CUSTOM_MENDEL_NAME "Cerberus MEGA"
...
//===========================================================================
//============================== Delta Settings =============================
//===========================================================================
// Enable DELTA kinematics
#define DELTA

// Make delta curves from many straight lines (linear interpolation).
// This is a trade-off between visible corners (not enough segments)
// and processor overload (too many expensive sqrt calls).
#define DELTA_SEGMENTS_PER_SECOND 200
...

... so that would explain why you get the strange behavior on your X and Y motors.

yes, I discovered that I am using wrong marlin software dedicated to delta machines.
