Fine tuning of Z height at zero
Printed first layer of the model has to smaller than equal to the first layer height in slicer. After upgrading MK2S to MK2.5S, I did fine tuning of Z height at zero by measuring the thickness of first layer. I … Continue reading

Steel Fisher – retraction calibration
I was printing a big model that has heavy support. It had a lot of retraction and during the printing, the nozzle hit a piece, dislocated, then spewing filament in the air. Two hours and 46 minutes of work wasted. … Continue reading

Original Prusa i3 MK2 – calibration and first printed object
XYZ Calibration compromised. Front calibration points not reachable. The solution of this error, the user manual says Move the left / right Y threaded rods in the Z frame away from you This is wrong. I had to pull the … Continue reading

Few comments about Mini Kossel
I want to discuss about one critical component that’s neglected by many builders. Qualtity and build precision of diagonal rod assembly dictates Mini Kossel’s printing quality and potential operational errors that would drag the user down. Six diagonal rod’s length … Continue reading

RepRapPro Fisher – 4
I figured it out why the shortage of filament extrusion last night finally. The right amount of force against filament at the geared shaft and idler bearing requires to provide good retraction. Extruding filament after specified length of filament retraction, … Continue reading

First layer of the printing object is so critical.
I play in the ten micron (0.01 mm) world. I’m so close to finalize Bulbul Junior 3D Printer but apparently there is one issue I have to solve, which is the Z height changes after few printing session. I suspected … Continue reading

Bulbul Junior 3D Printer operation log – Day 8 (2nd week of 3/2015)
The major cause of excessive uneven print bed was the loose joints of four diagonal rods. Source http://boim.com/misc/deltaCalTools.zip # octave script # # Current Delta geometry values: # X (Endstop Adj): -8.29 # Y (Endstop Adj): -7.19 # Z (Endstop … Continue reading

Building of Mini Kossel 3D Printer – 22
It turned out each Kossel Mini kit maker uses modified Marlin firmware that suits their 3D Printers. Marlin Blomker version which I’ve referenced heavily started working flawlessly right after the upload firmware. avr-objcopy -O ihex -R .eeprom /tmp/build5776194644516541631.tmp/Marlin_delta2.cpp.elf /tmp/build5776194644516541631.tmp/Marlin_delta2.cpp.hex Binary … Continue reading
