[1.75 nylon instead of the 3.0]

I have just run some trials with 1.75mm filament in my Ultimaker. Video on Youtube next week. Simply get a meter of PTFE tube and insert it into the bowden tube.

[KISSlicer]

Can someone give a simple answer to how we would account for different nozzle sizes in kisslicer? I have a 0.4, 0.5, 0.6 and 1mm nozzles and using 3 and 1.75mm filament.

[Nozzle assembly re-design]

Hi Everyone,

I have now redesigned the Peek component in conjunction with makergear brass tubes and nozzles and have been printing for quite some time with out back pressure, nozzle leaks and bowden tube popping out of the peek component. You will need access to a lathe to machine this :!:

[Heated Bed Ideas & Questions]

Have a look at my solution

Uses a Mk2 heatbed reprap

[New Mk2 extruder design]

Here is my Mk2 Ultistruder design which uses a Makerbot Mk6 drivegear. http://www.thingiverse.com/thing:19551

I have been using this for three weeks for 5 hours per day with out failure. It also works best with my modified PEEK component - http://www.thingiverse.com/thing:20535 at the nozzle end which is made from PTFE at the moment.

[Glass build plates]

You can not cut toughened or annealed glass they are secondary processes ie more cost and delay. I just tried it at work as 6mm glass was about $35AUD per meter. I would just use aluminium as its more robust and only expands < 0.5mm.

I also had to scale the key ways in the thingiverse AI drawings by 1.15 in Rhino. the final version is on my thingiverse page

[New Extruder design - MB Mk6 Gear drive]

Tom, thats the one! re the bearings look at the web link above. basically they are ID6, OD10 & 3mm width. You can print it in either material. However, you need a heated bed to print ABS successfully.

 

This is the drive gear you're talking about correct? :

I seem to be a little lost on the bearings though. I'm not very familiar with how bearings are measured. Can you link an example 106x3 bearing that would work for this?

Additionally, would this be printable in pla or would it need to be in abs since it has direct contact with the motor?

[New Extruder design - MB Mk6 Gear drive]

Hi Owan,

You need the Mk6 gear and two 106x3 bearings from

http://www.hobbyparts.com.au/

and some cap screws etc

I've just used an OEM spring probably get one from the "big green shed"

[Cracked brass printer head]

So I have been having continual problems with my printer head leaking back up through the thread and through the heater block. To try and stop this I added high temp plumbers tape This worked for some time however, I notices a crack appear in the print head and then it pealed apart on disassembly :( .

The nominal wall thickness of the UM 0.4mm print head where the brass tube bottoms-out is 0.34 mm!

Have ordered several 0.4mm print heads, teflon coated MB http://store.makerbot.com/makerbot-mk6-nozzle-teflon-coated-0-40mm-width.html 'new heater block required' and MakerGear http://www.makergear.com/products/nozzles. will post images when finished.

Also I am re designing the head for drop in/out interchangeable heads that will be one piece design and compression "surface" clamped in a new PEEK component. The Fortus 900c http://www.fortus.com/products/fortus-900mc.aspx uses a similar method. will post images when finished.

Thoughts anyone?

Scott
