is there life

looks pretty dead round here, is there any RepRap life remaining in Brissy

Hi,

I am forever mucking around with my prusa i3, and I am slowly gathering bits to build an Eustathios variant. What about you.

Just built a Tri-Colour Mendel 3.

Nice, got any awesome prints that you are proud of, where in Brisbane are you.

Warner lakes

I'm Still getting to grips with it, had a few issues with the homing and orthographic compensation, but I've managed to print some pretty cool traffic cones , and have printed a replacement part for my busted shower head, which has worked pretty well.


I've been trying to print some gyro cubes but have not had a great deal of success, getting lots of artifacts and parts coming detached from the platen.

What kind of plastic are you using? What surface do you have on the bed?

Im just using PLA and the bed is Kapton tape, I think I've got a handle on the detachment issues, but the artifacts are a real pain, particularly when printining a part that has multiple colours per level.... heres what I mean



You see the cones are great, but the cube which prints great in single colour just looks really bad in multi colour even after I fettle it.... the failed print on the left shows what it looks like before fettling.

I may try it again with cooler extruder temps and increase the extruder retracts at colour change... maybe slow the print speed a little too

Which slicer are you using. I'm using Simplify3D, their latest release has an ooze shield. not sure what cura and slic3r have in their latest release.

I've been looking at Simplift3D, but whilst they do a lot for dual extruder printers their tri extruder printer support is not too hot, it does have some nice features though, will look forward to them extending the same level of support they have for dual extruders to tri coloured

Hey bgkdavis ,

Have you been to HSBNE? (http://hsbne.org/)

I haven't been there personally, but it could contain a lot of 3D Printing activity for you Maroons .
It looks like a very well presented hackerspace based on the website.

Yes, I highly suggest checking Hackerspace Brisbane out.
I've only been once, but I can definitely say it is an awesome space with quite a few RepRap printer owners (and some other types of printers).

well Ive given Simplify3D a go and this is what the print looks like with the ooze shield still on the bed, you can see there are a lot of ooze artifacts, but they are all attached to the shield



Once I peel the ooze shield off then it looks like this, a LOT better. For most single extruder prints I think Slic3r is perfectly adequate, but it clearly lacks some multi extruder functionality that Simplify3D has, and definitely to be recommended in this case.

YES! I have a RepRap (recently purchased) which I am trying to get to run with Ubuntu 14.04. This is not being very successful so far (still haven't printed anything as yet). I am working through on-line manuals and documentation and forum comments to get a comms issue resolved. Would be interested in any help to resolve.

Have fun, I know its not trendy to still use windows, but it works.

Hi OzzieEngineer, did you get it working yet? I have connected my printer to ubuntu and got it working, right now my printer is running off RAMPS connected to a raspberry pi running Octoprint. It's awesome. What electronics is on your reprap? Does it enumerate in Ubuntu?

Hi dansxmods,

Good news and bad news. Good news is that I got it all working and it prints great! I found that dust had accumulated in the extractor. Once I had totally cleaned it, it was extruding really well. I also found that my bed wasn't completely flat. The clips at each corner of the glass plate were pulling down the glass.

Now the bad news - I had to use Windows to get the software stable. I think it was more the hardware I was using (an old college laptop discarded by my son). Now it sits next to me in the study, printing happily on PLA. I want to try using a memory card to "cut the cord" so I don't need to have the PC connected all the time. I also still want to try Ubuntu again on a better piece of hardware, now I know the printer works fine.

Thanks for the reply!

Of course I now realise that by running on ubuntu, your actually using computers to drive the printer, I don't have that problem, both my printers are fitted with Duet controllers and run completely stand alone and are OS agnostic.

ozzieengineer,

Assuming your machine uses a standard control board (RAMPS 1.4 or similar), I strongly suggest getting a "RepRapDiscount Full Graphic Smart Controller" [reprap.org] which has an SD Card slot, and also has a display screen and rotary control button. Once you have modified and flashed the firmware, you can "cut the cord" to your PC altogether, and drive / monitor all functions from the graphics display. Slice your STL fies on your PC, copy the G-Code onto the SD Card, and then put the SD-Card into the slot on the Smart Controller.

You can pick up Chinese clones on eBay for less than $20 (best $19 I've spent on eBay in a long time!), and if you don't have a compatible controller card, you can pick up a fully assemebled RAMPS 1.4 board for even less.

My board is a Melzi Ardentissimo with an SD card slot on it. The manual instructions (in Chinglish) says I can load a gcode file in the root directory and run it from there. I am yet to try it out.

Cheers!

There is also an LCD controller option for the Melzi called the Panelolu2 [reprap.org] but I have no experience with this hardware set-up.
