@Ghazi Do you mind sharing you Config, X & Y & Z homing files.
-
@Karim I donot have the printer nearby. I can help if you share the homing files you are testing right now

@Karim X & Y end stops M574 define high-end M574 X2, M574 Y2 switch them to low-end M574 X1 S1 p"xstop" & M574 Y1S1 P"ystop". The homing files should move in the negative values -355. Also, did you fix the mixed in wiring A & B motors
-
@Ghazi Ok that make the + movement for X & Y crash into the endstop.
-
@Karim My configuration might look different. The first config file in this post looks fine, but after switching A and B motors in the motor mapping M584 X1 Y0 Z5:6:7:8 E3. I attached a simple image for the x and y axes and where the original is on the printing bed (0,0) in the configuration
The point in green would be (350,350 ,0) after homing if you keep your current homing files. -
@Ghazi So you moving in the Negative to home X & Y.
-
@Karim Yes
-
@Ghazi ok X & Y is moving in the Negative when homing. I need to work on Z end stop, I am not using a probe.
-
@Karim IF you are using a switch endstop for z, first align the extruder to be above the z endstop. I use a G1 command then the position in X and Y before switch to relative position. The position of my z endstop is (X=230,Y=0)

@Ghazi Here is my Z homing.

@Karim if you move x or y before homing z, it would not work correctly
just switch line 5 and 6 to be like this,; homez.g ; called to home the Z axis ; ; generated by RepRapFirmware Configuration Tool v3.3.13 on Fri Oct 14 2022 18:23:21 GMT-0400 (Eastern Daylight Time) G1 X115 Y0 ; align the extruder to be above the z endstop G91 ; relative positioning G1 H2 Z5 F6000 ; lift Z relative to current position G1 H1 Z-355 F1800 ; move Z down until the endstop is triggered G1 Z5 F100 ; lift Z relative to current position G92 Z0 ; set Z position to axis minimum (you may want to adjust this) -
@Ghazi ok , after z endstop does x and y home. Also does the nozzle go back to the xy stop.

Can you help with this:
I'm not sure what you're asking for help with. Those are heater configuration commands, but what seems to be the issue?
-
@Phaedrux hey I am trying to set up the bed and hotend, I am looking for a starting point. I don’t know if this is ok. This was generated with the configurator. I don’t know the thermistors value.
-
Ideally you'd be able to find the thermistor values from the manufacturer. Those values are pretty generic, so should read something at least, but they may not be super accurate at printing temp.
-
Nevermind I see you have a dedicated thread. Assuming your homing is now working for you I'll mark this thread as solved.
