My take on a SuperD

[IBGold]

On my Glass bed I use cheap ladies hairspray works a treat but I only print ABS.

I have a taction plate but hairspray works on glass.
Make sure your extrusion rate is not too fast or the ABS does not get hot enough on some machines.
I print the coil so there is maximum area in contact with the plate also.
My printer is enclosed and that does help with thermal stability.

Tried hairspray but it did not work to well. Perhaps I need to change my brand.

Quickly coming to realise that I need an enclosure. My workshop is not heated and can get cold overnight. ABS and ASA-X are both temperature sensitive. Seems the upper layers are cooling and contracting more quickly than the bottom layers thus causing the warping.
Unfortunately, Mrs B will not allow me to use my printer in the house.
Thanks for your help.

Everyone I know that got a 3D printer found the printer needed an enclosure to maintain a constant temperature.

The first 3D printer we got at my work, they put a cardboard box over the printer. This worked well and is a cheap option.

The other thing is they always needed to tweak the settings, temperatures, rates, etc to get a good print with each type of filament.

Thanks Waltr,

Apart from the bottom layers the print is good, so tomorrow I will start designing a cardboard box, sorry enclosure, for my printer.

Yes mine is in a plexi-glass housing.

Thank you. I do have Fusion 360 but do not use it enough as I prefer 123 Design. I think this project will give the kick I need to change my habits

The attached zip contains the Fusion 360 project and step file for the SuperD Coil assembly.

Looked at manufactures "tents" and I am not impressed, so plexiglass it is. Funny how one job always leads to another.

This might give you some idea home brew as you can see.

The design I have in mind is very similar to yours. Aluminium angle frame, door at the front and removable sides. Must say that I envy the space you have. My workshop is quite small so the overall size of my enclosure will be just sufficient to house the printer. One challenge that I need to overcome is that the build plate moves forward on completion of the print. I either need to disable this function in software or design an auto opening door
Kind regards

You might be able to stop your build plate moving by modifying the gcode before printing file ... this is an example end of print code ... dunno what yours will say.
Edit the G1 Y200 line ??

eg

M104 S0 ;extruder heater off
G91 ;relative positioning
G1 E-1 F300 ;retract the filament a bit before lifting the nozzle, to release some of the pressure
G1 Z+0.5 E-5 X-20 Y-20 F{travel_speed} ;move Z up a bit and retract filament even more
G28 X0 ;move X to min endstop, so the head is out of the way
G90 ;absolute positioning
G1 Y200 ;Move bed forward
M84 ;steppers off

Thanks moodz,

My first venture into G- Code. Please see comment I have added to line G1 X0 Y220 ;Present print

M140 S0
G91 ;Relative positioning
G1 E-2 F2700 ;Retract a bit
G1 E-2 Z0.2 F2400 ;Retract and raise Z
G1 X5 Y5 F3000 ;Wipe out
G1 Z10 ;Raise Z more
G90 ;Absolute positioning


G1 X0 Y220 ;Present print I believe it is this one. Do I delete or Edit. If I edit, what do I write?
M106 S0 ;Turn-off fan
M104 S0 ;Turn-off hotend
M140 S0 ;Turn-off bed


M84 X Y E ;Disable all steppers but Z


M82 ;absolute extrusion mode
M104 S0

Hi moodz

Think I have just answered my own question.
G1 X0 Y220; If I go into printer settings and change the value of Y to that of the home position, then the bed will not move forwards at the end of print
