You look like you have serious over heating issues Your either extruding far to hot or need to add cooling fans or both. You can also turn on the cooling features of your slicer... Basically the first layer is not being given enough time to solidify before the next lay is put down. Gets worse the smaller each layer is. You can also print multiple of the items, to extend each layer time anby Dust - General Mendel Topics
Check the following. This presumes a I3 type machine where the bed moves in the Y Axis Firmware: (presuming you have a ramp motherboard) You have to set your reprap mother board to the correct type. #define MOTHERBOARD 33 for a normal ramps, or BOARD_RAMPS_14_EFB for new firmwares. motors (as viewed from the front of the machine.) move x in -ve direction head should move left, +ve directionby Dust - Reprappers
You need to change your board type from RAMPS_14_EFB (Hotend, Fan, Bed) to RAMPS_14_EEB (Hotend0, Hotend1, Bed) If you dont want to do that for some reason, you need to add the following line to pins_RAMPS.h #define HEATER_1_PIN {###) Where {###} is the digital IO pin you have you second hot end heater wired to (via a mosfet or relay of course) Add it to the section that matches your boarby Dust - General
The idea behind the ramps test is no matter how badly you have may have stuffed up marlin configuration.h this test will work and verify your hardware. 1) it only work on ramps. To extend it to support multiple boards would break its very simple nature. 2) you run this once... why would you put this in your firmware 3) you can emulate most of this test on the real marlin with a few simple gcodeby Dust - General
The stepper driver modules (pololu or what ever your using) are configurable Under each module is 3 jumpers (add 1 to the m labels, different sources for images) You set the micro stepping according to the following. Most people set all axis to 1/16th micro steppingby Dust - Prusa i3 and variants
If you do the basic maths for stepper rotation, toothed pulleys and belt type you probably do get 80 steps/mm its a very common value I would suspect you have totally failed to install micro stepping jumpers (3 jumpers under each pololu module) Without these everything would move 16 * the expected distance, and be very jerky and loud.by Dust - Prusa i3 and variants
By duty cycle I presume you mean percentage complete? not easily The computer has access to the entire file, so it can load it, find out how long it is, show you the progress The controller doesn't know the file length, it has only seen what has been sent to the printer. Even loading from sd, it just load the file line by line, no way to find out how long it is... (that I know of, might havby Dust - Reprappers
what about Homing speeds, which you have conveniently not shown The defaults are // Homing speeds (mm/m) #define HOMING_FEEDRATE_XY (50*60) #define HOMING_FEEDRATE_Z (4*60) Ie the last one should be 2*60by Dust - Firmware - Marlin
Are you sure of these are 2mm pitch acme leadscrew, url to source? If they are multi start vs single start then that changes things, take a look at them end on.. single start you can only see one start and 4 start for eg you see 4... 4 start would explain what you seeing perfectlyby Dust - Firmware - Marlin

1) check you endstops status with M119 comand. when endstops are triggred you cant move -ve 2) as a guess I would say z max feed rate is probably to highby Dust - RAMPS Electronics
Your math looks right I would guess you have and eeprom enabled and you updated your configuration.h with the new steps/mm values The eeprom takes precedence over the configuration.h Send a M503 and check your steps/mm are what you expected. To reset eeprom to values in configuration.h do a M502 then a M500by Dust - Firmware - Marlin
From in front of the printer... Are you looking down from above with the Y motor toward you? NO Are you looking down from above with the Y axis idler toward you? NO Are you looking from the front with the Y idler pulley closest to you and the X motor on the left? YES? (y idler can be either end, x motor can also be either end, depends who designed your printer. Most I3 type machines have itby Dust - Prusa i3 and variants

All you need is a tri color led eg You connect each color to a IO pin.

@Roger123D he is talking specifically about official Prusa i3 plus firmware, which have features that are not in standard marlin or repetier (at least not yet) IE The auto X/Y calibration stuff based on the special marks embedded into the heated bed.by Dust - Reprappers

the Makefile is very very badly maintained, as most people use the GUI Also most don't compile on Raspi3, are you just a glutton for punishment? regardless, if you load this in the GUI you still error "Versions of Arduino IDE prior to 1.6.8 are no longer supported, please update your toolkit."

This often occurs if you have the firmware set with the endstops at one location but they are really at annother (mins and max endstops all muddled up) you have // ENDSTOP SETTINGS: // Sets direction of endstops when homing; 1=MAX, -1=MIN // :[-1, 1] #define X_HOME_DIR -1 #define Y_HOME_DIR -1 #define Z_HOME_DIR -1 but where are you endstops on your machine, and what type of machine do you hby Dust - Mechanics

The second power plug is the bed only, its designed so you can have different supplies Increasing the voltage to 13.5 improves things a lot NB the 11amp poly fuse on the ramps for the bed, most are only rated for 16v. So if you go beyond that you will have to replace the fuse. Most just replace the polyfuse with a thick wire. then put a inline fuse in the wire to the bed.by Dust - RAMPS Electronics
