ATOM 3D Printer Group 造訪社團 » 線材相關話題

最近玩了蠟質的料！
只能說完全不會牽絲實在很爽！
160度就能印比PLA感覺還順啊！

熱床來了~~
回國後馬上拆禮物的感覺

但之前只用過PLA
想請問社團內有用ABS的人
能推薦你們都買哪種ABS嗎??
迫不及待想試了

請問各位前輩，成品列印後(abs)，所產生的表面線條狀，如何把線條磨除？

Strange printer behavior - what to do?

After performing an Auto-Home function, when I begin a print the printer makes a "jump" before it moves the printhead down to the printbed. The jump is really more of a jerk type movement that it never did before. The net result is the printhead ends up in the wrong place (too close to the printbed) to extrude properly.

It seems that the jump motion causes the printer to lose track of its vertical position, but I can't figure out why it has started doing this for no apparent reason.

To deal with this I have reloaded the printer firmware (twice), spent a lot of time with Z-offset, verified all the mechanical parts of the printer are ok, etc. The problem happens with both Craftware and Simplify3D, so I don't think it is a GCode problem.

This is the beginning of the S3D GCode:
G90
M82
M106 S0
M104 S190 T0
M109 S190 T0
G28 ; home all axes
;G29 Z+0.6 ; AutoCalibration
G1 F5000 Z50 ; lift nozzle
G0 X0 Y0 Z50 ; parking
G92 E0
G1 E-3.0000 F9000

and this is the CW:
G28 ;Home
M109 S200 ;set and wait head temperature
; ------------------------------------
; Layer #0
; ------------------------------------
G21 ; mm
G90 ; abs
G92 E0 ; reset extr
M106 S0
G0 F9000 E-3.0000

I guess there is some truth to the saying "It's always something."

Maximum print size

The Atom2 specs say the maximum print size in the X - Y direction is 220 mm. Actually it is about 244 mm.

The first photo below shows a part I printed that is 235.4 mm wide. I printed it on a 260 mm diameter Zebra Plate. There is a skirt of 2 loops printed 4 mm away from the part, so the total printed length is 235.4 + 2 x 4 = 243.4 mm.

The second photo shows Craftware's view of the part on the printbed. Since the Zebra Plate is 260 mm in diameter I specified 260 for the printer X & Y values in Craftware's Options dialog. Needless to say these 2 images agree quite well.

I did try to print a slightly longer dimension, but there were 2 problems: (1) the printhead's bottom cover bumped one of the clips holding the Zebra plate (scary, but that didn't affect the print), and (2) the printer crashed trying to move to a position the arms could not reach. So I'd say the maximum X or Y dimension the Atom2 can safely print on a Zebra Plate is 236 mm if you also print a skirt (which I always do) or 244 mm with no skirt or brim.

Same GCODE, same PLA, different ATOM machine. Any idea?

考慮到將來可能會常常更改擺設，所以不想在房間牆壁打釘子，沒有找到適合代替鐵釘的掛鉤，所以印了一些小零件，搭配無痕掛鉤的膠條，測試後發現PLA和黏膠的相容性不錯，滿牢靠的
沒有複雜的設計，但是簡簡單單的就可以很實用
同場加映，ikea的吸盤掛鉤，可拆換的卡吮設計很適合用3D列印設計配件

Improved planter & tray

This is an upgraded/improved version of my previous design. The changes are:

Rounded planter compartment corners provide a more organic shape
Planter & tray top edge is rounded instead of flat
Planter compartments are tapered to make changing/removing items easier
Tray has higher sides so reduce likelihood of spills.

The STL files are available here

這就是分工合作！選擇部件的顏色交給兩台機器一起打印，我的鋼鐵人版miniplan很快就能印好了！

最近噴頭又堵了 一樣又清出一堆黏黏的物質 200度加熱久了還會焦黑冒煙
請問這是鐵氟龍管或是PLA嗎?
