You can try it

Sure, but how to mount it, E3D does not have any holes.

It is a hard problem about mounting without any metal accessories.

You can try like above link.

No wheel?? What is impossible!

We dont use linear bearings and steel rods for X/Y movement. We use aluminum profiles with a PTFE coating and it moves very smooth and quietly. You can use PTFE (Teflon) aerosol to maintain the effect (a little bit every month)
用鐵氟龍噴霧來保持滑順...這真的長見識了

看了一下，如果是贊助15USD的話可以拿到所有列印件的STL檔跟Sketchup檔，還蠻划算的。

請問你的風扇轉速是多少

4000 RPM. This fan http://www.cooltek.de/....../silent-fan-4010-4-000-rpm......

take a picture

I didn't see any obvious problem in your cura profile.
What STL file are you print? Can you upload the STL file and take a picture of first layer?

I've done some more testing. It seems with lower bottom layer speed I am getting good quality now. But the PLA I have is very different depending on color :(

Do you mean you want to modify the gcode then you can print raft and skirt together?

I can give it a try. could you send me the gcode separately?

Actually I want to have it in the start.gcode of Cura. So independent of any model.

This is my current start.gcode: ;Sliced at: {day} {date} {time}
;Basic settings: Layer height: {layer_height} Walls: {wall_thickness} Fill: {fill_density}
;Print time: {print_time}
;other temp:{print_temperature}
;ideal temp:{print_temperature}
G21 ;metric values
G90 ;absolute positioning
M82 ;set extruder to absolute mode
M107 ;start with the fan off
G28 X0 Y0 ;move X/Y to min endstops
G28 Z0 ;move Z to min endstops

wow, I see. But you have no idea what size raft you need when you print, right? So, I guess it is easy to setup a certain raft size then you can start printing.

It will be a challege when the size is a varible

hm, you a right. Or at least some kind of anchor could help. Basically a line from X0 to X15 and then start printing

I would suggest you use Repetier-Host to help you understand what is the meaning of gcode

as you can see, I can easily point to one line and know what does it mean right away!

you can start from here then copy to your plugin

Do you mean like this?! print a line before brim or object print?!

yes

Follow as is my start gcode. you can copy the section of ";Print a exta line " to ";End print line" into your gcode

M0 ;waiting install filament
G21 ;metric values
G90 ;absolute positioning
M82 ;set extruder to absolute mode
M107 ;start with the fan off
G28 X0 Y0 ;X/Y home
G28 Z-4.67
G1 Z5
M0 ;waiting install platfom

;Print a exta line
G92 E0 ;zero the extruded length
G1 Z0.2
G1 F1500 X5 Y10
G1 E6
G92 E0
G1 X5 Y120 E10
;End print line

G92 E0 ;zero the extruded length again
G1 F3000
;Put printing message on LCD screen
M117 Printing...

This looks good! Thanks a lot. I only will change the F3000 to lower value. Need to test.

Extruder fan must be full on to maintain hot end temperature,fan on the board which cooling the motor driving ic running on 100% also make sense, the fan needs to be controlled is which cooling for freshly laid down filament :D

Yes, but the firmware still needs to control the extruder fan and not the board one. It's not about always having 100% but about controlling the RPM.

Ok, now I understood what you mean. Actually there should be 3 fans. 1 for the parts (controllable), 1 for the hotend (always 100%) and 1 for the board (also 100%).

You got it
