BFB 3000 questions
Hello, I was fortunate enough to be able to purchase a BFB 3000 about a month ago and being new to any 3D printing I have several questions.
First, I can't seem to be able to change settings on the fly. After pausing the printing and changing the settings, the screen never shows the changes even after resuming printing (The firmware is up to date).
I was also wondering what the best way to remove the support material (PLA) is. Is there a certain liquid solution that works for this?
My last question is regarding heating the bed for reducing warping. Someone recommended using a heat lamp but I wasn't sure what type or size of bulb would be best to use for this.
Thanks an advance for any help or suggestions. :)
Acetone will melt the ABS!
Also which firmware version do you use (along the top of the display).
I can change my settings on the fly but I do not pause it and to change just press the buttons whilst printing. The change will only take effect (I think) at the next line of Gcode. So if it is printing a long line there may be quite a delay. But as said above changing on the fly might have problems.

Haha yes I forgot about this, my mistake!
(Although you can dip an ABS piece into acetone briefly to strengthen it)
note that while ORBI's pla is nice, ANY PLA will not warp !!
Chylid yes I 'acetone dip' to make much better finished items.
Got to get time to change to PLA??? Had BfB stuff for ages and now have orbi all just sitting there. The machine is in constant use so finding time is difficult. From another thread I have ordered a 3000 so this problem should be over soon ;D ;D ;D ;D ;D ;D

It is well worth the time to change :) It prints much nicer and even smells nicer too when printing! I am finishing up my first raftless print now, can't wait to see the finished product...
@John, the firmware on the machine is 4.0.2.
I'm interested in trying the Orbi-PLA. Does anyone know if the spools for that will fit a BFB 3000?
thanks again, much appreciated!
The BfB spools of PLA are exactly the same as for ABS. I have a few different versions. The Orbi stuff I got is on a big reel. I have a holder for it but will have to find a way of feeding it in with the reel outside the 3000.
After checking the prices on the Orbi-PLA I might have to hold off on that for a bit, shipping costs here to the US may get a bit expensive. I was wondering though, will any 3 mm filament work with the 3000 as long as it's the right size and material suitable for 3D printers? I've just noticed there's quite a few other places that sell filament for other 3D printers and the material is the same size but i wasn't sure if they're compatible.
I think any 3mm filament should work. Shipping to Australia was also very expensive, I think I paid almost as much for shipping as I did for the PLA itself. However even then, it worked out to be half the price of BFB ABS! I've since found another PLA source that is cheaper by half again, but I'm seriously falling in love with this orbi-tech stuff....
I get my PLA from Ultimachine.com and I haven't been disappointed, though it's just normal PLA, not the special Orbi stuff.
Check out their blue translucent PLA, which glows nicely under blacklight (UV).
yes, ultimachine is a good source. Great results with natural and black pla. didn't like the white, but didn't spend any time with it.
In the past there has been problems from some suppliers of filament that was not carefully produced and the diameter would vary a bit. This would then make the filament stick in the extruder. I bought most of my filament from BfB as their quality control seemed very good and an extruder block is a pain. Having said that I have just bought some Orbi-Tech PLA and I did get a reel of ABS from another German company but cannot remember the name.
I would not buy cheap stuff unless someone else recommended it and had risked their extruder. :o

Hi John,
at the moment I have a funny low temperatur filament with only 2.4 mm and it´s possible to work with in my one head extruder. Problem is more the feeding and less stiffness.
I think nozzle blockages are mostly thermal problems as described above.
OK more than 3 mm can not work.
edit: I mean not the new PLA.

I agree that most of the blockages (perhaps 100%) now are temperature and material related but in the early days (wow not that old, well I am but not in rapman years) there was a lot of talk of filament that varied a lot in diameter and quality and it was said to stick with BfB as this was always good. I would think things have moved on and if filament says will work in a machine I would think it should be good.
Welcome to the forums! I only have a Rapman 3.1.1 but let me see if I can help.
Changing settings on the fly doesn't seem to work in my Rapman's current firmware either, but I think this will be fixed in the next version. This wasn't a problem for me once I began making my own BFB files (using Axon)
If you print ABS with PLA support material, I believe you can partially dissolve the PLA in NaOH (sodium hydroxide)
or Acetone. Be careful with these though :)Anything that gets the bed up to over 50-60C should be ideal. Or you can use Orbi-PLA which simply doesn't warp :) (I just had mine shipped from Germany to Australia and I LOVE it)
