I don't think my batch-1 has a serial number.. Did they add them to later batches?

Dunno if it will be available soon but I don't see any reason why it'd require a whole new machine.. The printhead might have to change if more space is needed but I think the current design was intended to allow multiple materials/colors.

..except if the second head is for support. Don't need two files for that.

So turn it up to 235C! I had a lot of issues lately with stripping and the extruder motor skipping steps. Turned out the filament drive bolt was too tight - sorta pinching the two wooden pieces together. Fixing that made things much happier. If you're not getting any motor skips, that's probably not the problem, though.

I'm printing at 230C.. Why not try 215 and see how that works?

Yup. This is something that netfabb has been sorely lacking. Skeinforge has the Comb module which does quite well. It's nice to see something similar coming to netfabb. Not perfect yet but a big improvement!

Here are a couple links of actual printed stuff: https://plus.google.com/u/0/?tab=gX#107 ... Nrpk9S9NzE http://davedurant.wordpress.com/2011/10 ... of-prints/

Yup.

Yes and no.. And no. Although there is indeed a hidden multiplier in my code (which is 12.461 - don't ask how I got this), the real issue is that the old-style number that netfabb and SF pre-40 use didn't really mean something specific. It was supposed to be the number of extruder steps that would cause 1mm of filament to come out of the nozzle. The problem with this is that the length of filament you get out the nozzle varies according to nozzle diameter and temperature and what sort of filament it is, even different types of PLA have different characteristics and how fast you were extruding (aka: die swell) and 97 other variables. It's a very fuzzy value.. The new style of things (SF40+, slic3r, etc) specify filament by the length of raw filament stock to pull into the extruder. If the slicer knows the filament diameter, it can calculate the volume of a line it wants to lay down, do a bit of math then figure out, quite exactly, how much filament needs to be pulled in to make that line.. The magic 12.461 is what I came up with to convert new style to old style in my program.. It's actually doing new style calculations based on thread width & height and filament diameter then throwing in this magic number to make it work with old-style slicers. The extra "and no" is because 5D machines (which we have) don't actually have a concept of extruder RPM any more.. That's more of a pre-stepper-extruder idea that's (thankfully!) long gone now. Netfabb hasn't updated yet, though. Eventually, once netfabb gets updated, there'll be no need to mention RPM any more.. It will tell (via gcode) the firmware how much volume it wants and the firmware will do the right thing to get the right amount of filament in the right amount of time.

I think there's a Marlin bug here.. I also notIce a small stutter, even at low speed. Definitely not because of the baud rate being too low - I've printed far faster at the same rate with earlier versions.

Which country are you in?

Very!

LOL.. I remember that moment for me, where I was thinking very seriously about slapping the power switch. The machine stayed happy though, so I let it print. Coming from a makerbot, an ultimaker is quite a trip..

I think they're pretty swamped trying to get machines out and probably get a bit behind.. I know they were advertising for support people to work there.. Out of curiousity, why do you want a HBP? Are you planning on printing with ABS? Yes, I do know! I know exactly!! I bought in on batch 1 and haven't regretted it at all..

I wouldn't worry about bothering us.. Forum posts are cheap - if you've got a problem or question, bring it! and, error1, that's how I adjusted my belts, too...

That came out great! You need some brass bolts on it now - steampunk 3d printer!

Finally starting to get a little more time to mess with printer stuff and actually printing tonight! On my todo list for this stuff is to add a fudge-factor tweak so people can adjust for issues like Joergan's 10% off one, though I'm still unsure on if that should be a global thing or per-thread width or per-feed rate.. Any thoughts there would be appreciated. Also is maybe a setting to force layer height to be a multiple of the minimum layer height the machine can do which, in theory, maybe, will help keep tiny layers consistant. Was there a consensus on that? Is it worth doing? And, of course, any other suggesstions would be great..

I doubt it's temperature and don't get discouraged - have patience, work one issue at a time and things will come together. Back on the thread you started, several people have suggested you've got a belt problem but you haven't replied on if you looked at that or not yet..

I don't think that's the problem plumbers tape is supposed to fix.. That, I think, is more about making sure stuff doesn't leak around the nozzle/barrel threads. Why remove the temperature probe?? Just heat things up to about 190C (or so..), and carefully, and while the hot end is dangling in the air instead of sitting on the platform, and use some needle-nose or something to pull the plug out.

The one I've been working on, and probably the one Daid's working on, shouldn't require any firmware changes on the machine...

Eh? See one post before yours.. I'd go with 44, which you can get at http://www.skeinforge.com - it's the one from 2011-10-08. You can get later ones if you want but I know 44 works fine so that's what I'll suggest..

Actually, since this has come up a few times lately, I'll just post it.. This is the one I'm using, which seems quite happy. It's 115200 baud, too. When the next stable version comes out, maybe we can get a mod to nuke this one. edit: and if you still have problems with this one, I won't go messing with different versions or modifying this one - something else is wrong. Don't worry, have patience, it'll be fixable.

I still have it.. It's called ErikZalm-Marlin-45464f8. Post or PM me your email and I'll send you a copy. I'd rather not post it here - once the next version comes out, don't want people using it any more. Stick with it! It's worth the effort, once you get it right. FWIW, I've got repg26 and am using stand-alone SF44, though SF47 is now out and I'll probably switch to that soon. The only firmware change I made was to make it 115200 baud.

Strange that I just did that firmware a week or 3 ago and have different values, though nothing jumps out at me as being seriously wrong.

His also says 1.0.0 beta 1 but it sorta sounds like he's got that software endstop problem with the 2 version.. I haven't really been following this stuff too closely - hopefully somebody else will jump in with a solution..

When you first start repg, you should get some text at the bottom of the screen - startup stuff from the printer.. Can you copy/paste that here?
