The Stepper Motors used on the Eaglemoss Vector 3 printer are Nema 17 specs right ? i.e Step Angle/Step Angle: 1.8 ° Voltage/Rated Voltage: 12 V Nominal current/Rated current: 0.4 A/phase1/8th Correct? So the jumpers on the RAMPS Board should be MS1 and MS2 for the A4988 - Yes? Therefore #define DEFAULT_AXIS_STEPS_PER_UNIT { 66.67, 66.67, 2560, 500 } should be 1280 NOT 2560- Right! 2560by IMPARTIT - Firmware - Marlin
My grateful thanks to you for your replies which served to clarify my "dumbness" on Z-MAX and Z-MIN positions and setting which had indeed confused me previously. BTW the Z-MAX-ENDSTOP switch is situated at the bottom left of the gantry furthest from the nozzle I duly set the following: #define X_MIN_POS 0 #define Y_MIN_POS 0 #define Z_MIN_POS 127.0 (physically measured - exactly the length ofby IMPARTIT - Firmware - Marlin
Have you tried setting Z_HOME_DIR 1 and using both #define USE_XMAX_PLUG and #define ENDSTOPPULLUP_ZMAXby IMPARTIT - Firmware - Marlin
After the burnout of the original Eaglemoss Mother and Daughter boards I determined to rebuild the Vector 3 printer using: Raspberry Pi, Arduino Mega 2560 and Marlin 2.x firmware. But I am stuck with Z Axis issues..... Many thanks in advance for your helpful responses . I was always puzzled Z_HOME_DIR 1 and Marlin telling me I needed to set the MAX_SOFTWARE_ENDSTOP_Z when the Vector 3’s Z microby IMPARTIT - Firmware - Marlin
Thanks - I have changed the Z-DIR to true and indeed it homes correctly BUT when printing the attached file the bed does not reach the first level and bed goes UP for each new layer. The same file prints just fine on a duplicate printer. line 19 reads G1 Z0.350 F6000.000 ; move to next layer (0) Could you try it please? Perhaps my software end-stops are wrong at: /** * Software End-stops *by IMPARTIT - Printing
I have tried everything but z-axis will NOT home CORRECTLY with G28, move to the 1st layer position or step in the right direction when printing: With the Configuration.h file having the following settings at the line numbers given: 1) 657 #define X_MIN_ENDSTOP_INVERTING true, 658 #define Y_MIN_ENDSTOP_INVERTING true and 659 #define Z_MIN_ENDSTOP_INVERTING true 2) 1089 #define INVERT_X_DIR faby IMPARTIT - Printing
