I think the EU bits are guidelines, in which each country is left to their own devices whether or not they follow it. As an R&D engineer I'm not the guy to say what the exact lifespan of the machine is, nor how we, as a company handle return policies (that's up to sales / management). What I did understood from previous times this discussion came up is that even though we offer an 'official' waranty of year, this does not mean that we're going to be assholes and stop helping you / replacing stuff after the one year mark. Within the software I use the 6 hours a day printing and at least two year (over 2k hours printing at +- 6 cubic mm/s) as a guide line for 'normal' usage. It's safe to assume that the printer should outlast that (as we should design for more than 'normal' usage)

Nope, sorry.

The extra power to move the bed is not the issue, the extra power to heat the bed is the issue. I'm not much of a mechanical engineer, but there are 3d printers that use 2 screws to move the bed, which seems to work allright.

Try pre-heating your bed. This sounds like a power issue. Heating the bed & nozzle at the same time causes the power supply to fail and turn itself off.

We don't have an expected lifetime that I'm aware of. With a product that is +- 2 years old (and a company thats +- 4-5 years old) much of this information simply isn't there (What kind of stuff do people print, how much, etc) I do think that most parts (save the teflon thingie) should easily last you two years.

No. We actually only do public tracking there. Most of the (bug) tracking is done on a private tracker that can do a whole lot more than the shitty one github provides. The best way to see if there is a stable release is to wait for the release. Inbetween releases tend to be somewhat stable and nightly tend to be unstable (although nightlies can be stable...)

With a much larger bed power becomes an issue. The current UM2 power supply is barely strong enough. If you have a larger heated bed, more power is required (so you probably need a separate power supply)

Upgrade your motion control board to something with a higher (micro) stepper count. If you use enough micro stepping you won't hear the motors anymore.

I think we meant "You can slap a doodle3d or octoprint on it" by that.

1.99 has an option in preferences for this. It's called something like 'automatic push free'

I know that Daid used to have a developer function in the engine that did exactly this. Not sure if it's still in there though.

It's possible, but we won't do it. For Ultimaker safety is more important than the few times the software incorrectly gives an heater error.

The firmware gives the heater error when not enough temp increase is reached within a certain time. Too much cooling on the head, not enough power for the heater or hardware failure can trigger this. The error is there to prevent bad things from happening if the hardware failure is the issue.

This is with settings directly imported from Cura. I'm going to try and see what their default settings do with the same model.

As far as I can see they might even use parts of Cura. I've seen a few behaviours that look awfully lot like what Cura does. So far I'm not that convinced about the GUI. It crashed a few times on me and I had to get the g-code from some temp files it wrote somewhere. I'll try and slice some objects to see how it works on a UM2

We don't support printrun anymore. It was a pretty bad hack. Most of the UM machines don't really need USB, so we don't put in a lot of effort to get that working right. We have bigger issues to tackle.

There is no easy way to do this that i'm aware of. The hard way is to divide the object into parts, give them per object settings and group them. You can do this with the new Cura.

Well. It's not often that you see such a blatant copy of something. Copyright usually doesn't protect you very well, but in this case it does. There is a "Report this project" button, where you can select IP as one of the reasons.

The new cura could do this with the post processing plugin.

Add these things to the github (ultimaker/cura). We can't keep track of all the requests on the forum. Some of the issues that you have are bugs, so we should definitely fix those.

Looks like you're trying to print too hot. Could also be old material.

I'm assuming you're using USB printing. In that case this can happen as we didn't put a lot of resources in that as the UM2 is offically not suported for USB printing.

"invalid gcode" is an firmware issue. "cannot cold extrude" is probably caused by weird firmware. It could be caused by Cura as some times of printer don't want a set temperature g-code before they start printing. Try selecting different printer types (UMO should work) to see if that helps.

I have no experience with this, but I'd love to hear more about yours once you receive it.

Have you tried only heating the bed (and nothing else?) It could be that all the systems combined draw to much power, causing the UM2 to turn off.
