do you use repetier host?there is an eeprom editor included where you clearly can see each setting.BTW z-axis acceleration seems too high , z-jerk should not be a negative value... with export file i just mentioned to save the data ;-)

Usually you limit the maximum z-speed in firmware,you can edit the eeprom settings via repetier host eeprom editor.so what i suggest is to find the feedrate limit via the manual moves , reduce that value to 80% and set theeeprom corresponding to tha…
-
to slow down just reduce feedrate to see what happens. so f.e. simply send a couple of manual codes : G1 Z100 F200G1 Z10 G1 Z100 F300G1 Z10 G1 Z100 F400G1 Z10 so you can see if it´s a general problem OR it´s speed related
-
so if you swap 2 and 3 in cable on radds side this motor should also work
-
ok so there are two coils , the left two wires should be one and the right two wires the second. can you measure resistance with multimeter (lowest ohm range) of each coil and compare to the working stepper? (use same cableset for measurement)
-
can you upload a pic of the not working motor?(connector and nameplate)
-
did you try to measure wire and coil resistance?
-
did you enable cold extrusion?otherwise stepper will not move without heat M302 S - allow cold extrusion. Without S parameter it will allow. S1 will allow, S0 will disallow.

try to print a square in half size , same height.if error is half then , adjust the steps /mm
-
several possibilities:motor not connected properly motor current is adjusted incorrect steps/mm don´t matchspeed and acceleration to high check motor connections and motor current , then i´d suggest to reduce z-axis homing speed first , try 5 at th…
-
mismatch in homing direction / installed endstop switch you have#define MIN_HARDWARE_ENDSTOP_Y true (endstop at y min) but #define Y_HOME_DIR 1 which means you home to y max. so two problems : if motor is homing in the correct direction its wrong …
-
ok, so keep in mind never plug/unplug motors in powered system, that can / will fry your stepper drivers.
-
thats what it should look like...and motors turning / heaters heating now?
-
Ok, unusual but if you are shure it´s okdid you check the red fuse? may be you can borrow one in your neighbours car ;-)
-
well , following the red and black wires are they power supply for both sides ?in that case what´s the brown and black wire?are you shure you didn´t swap something?
-
OOps... printer in fragments.... wouldn´t it be better to kick that frame and make a complete rebuild ?
-
there are green led´s near fuses these should lbe illuminated.maybe check the fuses (the red one is for the motors) can´t see it in the video as the stepper wires block view
-
did you connenct both power supply inputs on the radds?one is for the motors , extruders and fans, the other one only for heatbed
-
well, i watched the livestream for a couple of minutes. seems the printers frame is quite weak at all.may be you try to get the frame more rigid.(looks like made from plywood so it should be easy makeable) for the pen test may be its better just to …
-
why -107198... it´s + 107198 (formula is absolute correct)
-
simple suggestion:try to fix a pen or pencil to your hotend and draw a square. that´s much more precise
-
well, i´m in germany , but if you have good soldering skills you can change the eeprom yourselfor you have somebody to change it for you, that´s -a EEProm costs lower than 1 Euro... -b would be something like this :https://www.ebay.de/itm/AT24C25…
-
May be you give this solution a try and erase eeprom with the arduino sketch from here : https://forum.repetier.com/discussion/5850/ruramps-v1-3-and-repetier-v1-0-4dev-work-only-without-the-eeprom-enabled#latest seems to be similar problem. another…

what do you mean?move both motors or move both directions?
-
as there are several ramps versions available just a question:on the left side of reset button(ramps board) there is a three pin header.is there a jumper located between VCC and 5V (the upper two pins) ?if not , there is no power supply to servo so …
-
What do you think is wrong with that behaviour?there is no "autoreturn". Servo moves to a position and stays there until you send a command where to go next
-
yes, values are saved to printer board, no need to keep laptop connected
-
what kind of z-probe do you use? Z_PROBE_SWITCHING_DISTANCE should be set a little higher than the distance the z-probe needs to switch
