This 3D printer was built back in 2015, I am adding this post here because I don’t remember much about it and i would need to rebuild it today for a certain project i have in mind.<\/p>\n\n\n\n
My 3D printer, Prusa i3 with RAMPS 1.4 and a heated bed, started off with the config file from the FolgerTech i3-2020, the 0.4mm Brass Extruder Nozzle, 30mm M6 Tube, FILAMENT 1.75 mm<\/p>\n\n\n\n
The entry that comes with the config files has a problem with DEFAULT_AXIS_STEPS_PER_UNIT, by default it comes with the values { 80, 80, 4000, 104.4 }, the third one (Z axis) has a problem that my rods are different, and the last one for the ext ruder has double the value assuming we have microsteps, So i reverted to the one in the 1.1.5 that is already installed, namely<\/p>\n\n\n\n
define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 2580, 52.2 }<\/pre>\n\n\n\nThe Z axis probably needs more refinement though, as the higher the build, the more problems you have close to the top<\/p>\n\n\n\n
In this config file, I have the MOTHERBOARD set to BOARD_RAMPS_14_EFB instead of 33, this is all good for the 1.1.5 and the 2.0.x, previously they were numbers, and they probably still are (Value of this)<\/p>\n\n\n\n
define BOARD_RAMPS_13_EFB 33 \/\/ RAMPS 1.3 \/ 1.4 (Power outputs: Extruder, Fan, Bed)\n define BOARD_RAMPS_13_EEB 34 \/\/ RAMPS 1.3 \/ 1.4 (Power outputs: Extruder0, Extruder1, Bed)\n define BOARD_RAMPS_13_EFF 35 \/\/ RAMPS 1.3 \/ 1.4 (Power outputs: Extruder, Fan, Fan)\n define BOARD_RAMPS_13_EEF 36 \/\/ RAMPS 1.3 \/ 1.4 (Power outputs: Extruder0, Extruder1, Fan)<\/pre>\n\n\n\nExtruder and heat bed<\/p>\n\n\n\n
Even though i use a solid state relay for the extruder, the heated bed uses an automotive relay switch, so PWM is a big no no, we will need to comment the line where it reads define PIDTEMPBED<\/strong>, we also MIGHT WANT TO (only if needed) to fix some stuff in config advanced file.<\/p>\n\n\n\nif DISABLED(PIDTEMPBED)\n #define BED_CHECK_INTERVAL 5000 \/\/ ms between checks in bang-bang control\n #if ENABLED(BED_LIMIT_SWITCHING)\n #define BED_HYSTERESIS 2 \/\/ Only disable heating if T>target+BED_HYSTERESIS and enable heating if T>target-BED_HYSTERESIS\n #endif\n endif<\/pre>\n\n\n\nthe above means, check every 5 seconds, the rest is self explanatory in the code comments<\/p>\n\n\n\n
Next, the end-stops, Z_PROBE_OFFSET_FROM_EXTRUDER for example (Height) is the most important one, as the others will simply print in the wrong location on the bed which besides loosing bed space is not really a problem<\/p>\n\n\n\n
Could not find this setting in Marlin 2.0, pending further investigation<\/p>\n\n\n\n
Now, the bed size, the whole bed is 20CMs, but there are screws at the edges, so I will go with 19 and add some 0.5 offset<\/p>\n\n\n\n
Remember to uncomment “PROBE_MANUALLY<\/em>” since i don’t have a probe ATM, also uncomment LCD_BED_LEVELING and leave RESTORE_LEVELING_AFTER_G28 uncommented (and leave ENABLE_LEVELING_AFTER_G28 commented the way it is)<\/p>\n","protected":false},"excerpt":{"rendered":"This 3D printer was built back in 2015, I am adding this post here because I don’t remember much about it and i would need to rebuild it today for a certain project i have in mind.
