That's a very good idea!

Hmmm... time for a glass of wine or level the bed? Decisions decisions.... :-)

Assembling Anders/Swordriff new heater block. Can't wait to try out the 0.8mm nozzle. Happy days :smile:

"Those that don't make mistakes don't make anything" Very true, up there with "those who have tidy desks don't do anything" :wink: I too was also dissappointed to hear there would be no official dual extruder in the offing. But I completely understand UM's reasons why. As Sander keeps posting "UM is all about the quality of it's prints" and I have high regard for UM in sticking to that ethos, That's something to be very grateful for. Quality is paramount. From a personal perspective, it just re-affirms that I made the correct choice in investing my money in (two) of these printers when I was looking for a 3D printer. There's been speculative talk of UM2 'upgrades' and on the forums whether third party add ons may eventually be added to the shop. I think that's a great idea. Anders heater block which takes E3D nozzles would be a very welcome addition in my view, amongst a few other bits and pieces. The future looks bright :smile: Edit: Check out Faberdashery for filament as well. Their PLA is quality.

Ummm.... from the photo, I'm not really getting what the problem with that print is ? :???: Edit: Ditto for the photo of your red print.

I think you've nailed it pm-dude. Both the zetoff and venkels fan shrouds have 'open bottoms' and at nozzle heights close to the bed the backwash from the fans end up cooling the heater block. At heigher head heights this doesn't happen as much - unless you're printing large flat surfaces... I should have thought of that - apologies! Most likely the other slicers won't help at all with this, but they're useful to have around. I've found KISSlicer is pretty good at generating supports - so that may be useful at some later date :-)

What he said :-)

That's pretty impressive, is there more video of more of it? :-)

For http://kisslicer.com/ There's some settings here which work with the UM2. http://umforum.ultimaker.com/index.php?/gallery/album/1757-kisslicer-settings/ It produced better supports than Cura for a particular print I've been attempting.

Just a random thought... maybe try it again with the same filament but with another slicer? Just to see whether it's Cura or the printer? I've always had more issues with white filament than any other colour I've used. I wonder if that's to do with the particular colorant ?

It looks as if the belts trying to climb up the side of the pulley... are the two pulleys in line with each other?

I'm seeing the bed being homed twice before the print. Is that the issue you mention here illuminarti ? Apart from that it prints perfectly! :-)

Got my UM2 working with KISSlicer. Here are the settings I'm using. http://umforum.ultimaker.com/index.php?/gallery/album/1757-kisslicer-settings/

Or you could look at PLA HT? http://umforum.ultimaker.com/index.php?/topic/8754-pla-ht/

Yes certainly. That's why I'm approaching this cautiously. It didn't help that my UM2 gave me a caution, warning me that I was overriding the printer settings... before I pressed 'continue' <gulp> My main reason for looking at KISSlicer was for the support generation it produced which gave better results "out of the box" than Cura for a particular print I've been trying. Here: http://www.thingiverse.com/thing:637261 Since then I've "discovered" you can generate supports outside of Cura and then import the whole thing back in as an .stl using this amazing free software: mishmexer, http://www.meshmixer.com/ I do want to persevere with KISSlicer as I've bought the damn thing and it seems to me that it's worthwhile perservering with. I've just got to get my head around it with the patient forum help here and also learn some Gcode in the process, which altogether isn't a bad thing! So yes, if I get it all sussed (I hope) I'll gladly post up all the settings that work for the UM2 :smile:

Lol! the joys of software development. Thanks for the confirmation. :-)

That's exactly what I'm seeing. Seems to be happening after the latest firmware updates as it definitely wasn't doing it before.

Ah. Good call. Thanks Robert. It was set to Relative E. I'll try it all again tomorrow.

Thanks all. :-) The settings for the bed are spot on. Now I've just got to work out why the bed wants to home twice before priming the nozzle and I'm then getting nothing extruded when the print starts... it appears that the feeder is retracting but not feeding the same amount despite those two distance settings being identical in KISSlicer. Very bizarre :???:

Daid, Have you sped up the filament loading speed in the latest firmware? If so, it's prone to making the stepper stall on my machine. Before, the speed used to sound as if it were "pulsed" slightly and that worked perfectly.

Thanks Robert, just to clarify, should the values for the origin be negative ? i.e - 115 and -112.5. I'm wondering that the center being 0,0 (for Kisslicer) then it kinda makes sense that the (UM2s) left hand front corner would be in a negative direction for both the x and y co-ords. Am I right in thinking that? I'd try running it, but I'm just a bit worried about banging my UM2's nozzle into the end stops.... :eek:

Thanks TinkerGnome, I'm guessing the origin will need to be offset by half the printer bed dimensions... now wondering if this should be -115 and -112.5. Hmmm.....

Ahhh.... is the UM2s X-Y origin (0,0) the top left hand front part of the build plate? i.e the position where the nozzle primes itself before printing? Kisslicer has the bed middle as 0,0
