Re: What to do about edge curl?

1) You can't get too much cooling when printing PLA. It needs to cool as fast as possible, to avoid shrinking away from unsupported edges. Insulating the hot-end is a good start, but you still need more cooling air than the stock fan/duct can provide. Keep in mind that the fan is taking in fairly ho...

Re: Source for PEI sheet with adhesive

Bet these sheets will Outlast the rest of the printer Very possible. I have one nightmare ABS print re. adhesion: 8" x 4" x 1/8", with a pattern on the top. Corner adhesion is difficult, to say the least. but with PEI set at 105C on the N2 (actual surface temperature around 80C) it s...

Re: Source for PEI sheet with adhesive

I always let everything cool down to room temperature first. Then if the part isn't easy to remove, I try the freezer to get a little more part shrinkage to pull it loose.
I've never liked using a palette knife - I've taken chunks of glass out of buildplates removing parts that way.

Re: Sudden Death of N2 - Support assistance requested

In retrospect, the bad fuse might have been mechanically defective. It is a glass tube type, and when I pulled it, it looked brand-new - no evidence at all of being blown. However, when I put a meter on it, it was completely open - no connection at all. I've never seen one of these look pristine aft...

Thanks. No wonder it is so delicate tweaking the bed height.

Re: Filament Brand suggestions

I would also vote for IC3D ABS. Costs less than Ultimachine, and seems to be good quality.

Z-height adjuster screw pitch?

What is the pitch of the bed-height adjuster thumb-screw, i.e. how much difference does one full turn of the screw make in the bed height?

Re: Source for PEI sheet with adhesive

After a light steel-wool treatment on the shiny side, it sticks like crazy with ABS - easy to remove after cooling, but it doesn't pop off by itself at room temperature, like gluestick does. I'm presently playing with lower (than 105C) buildplate temps to see how that works for a bit less adhesion. ...

This company sells PEI (Ultem) sheet in your choice of thickness, with 3M adhesive pre-applied for easy installation. http://catalog.cshyde.com/viewitems/3d-printing-materials/ultem-pei I chose .020" = .5mm as being stiff enough to apply easily without bubbles, while thick enough to last a whil...

Re: Sudden Death of N2 - Support assistance requested

The power switch/fuse/socket is a single unit - that's the fuse that popped. There is also a hole to keep a spare fuse in the removable fuse holder.

Re: Sudden Death of N2 - Support assistance requested

Contacted R3D and diagnosed a blown fuse in the power switch. It's a 5A 250V. - $7 for two, at my local hardware. It makes me a bit nervous as to why that fuse popped, but I'm back in action for now. For the future, R3D should consider putting a spare of these fuses in the Care package that comes wi...

Re: Sudden Death of N2 - Support assistance requested

I'm pretty sure the power supply is under the printer, while the controller board is inside the box near the spools. No fan is running, so I'm guessing power supply or switch.
In any case, i'll be working this over the phone with Raise3D today.

Sudden Death of N2 - Support assistance requested

I have an N2 Dual, s/n 10091710013, purchased from Amazon June 19, in the US.

While printing ABS today, it suddenly died, and now the Power switch has no effect at all. It's totally dead, and I have orders to print.

Help!

Re: Error in Cura printer definition = underextrusion

Yes - it ruined a months' worth of prints for me, as I was printing ABS, and could not figure out why I was getting significant under-extrusion.
That's a really nasty error - a really dumb thing to default.

Dual N2 with Right extruder removed - load single or dual firmware?

Title says it all: I'm using an N2 dual-extruder as a single-extruder machine. I've removed the right hot-end.

Question is: for the new frontend firmware, should I load single- or dual-extruder version for the control panel?

Stating that there is a major issue with the heated build plate heating element on all Raise3D printer is not really valid. Did someone say that? I, at least, just said "be aware" that the buildplate heater temp is not equal to buildplate surface temp. So, to get to the usually-recommende...

Re: Be aware - Actual buildplate temp lower than temp setting

Once it stabilized, heating on mine was very even, but quite low compared to the set-point.
Clearly it needs correction, and I'm glad I took the time to investigate.

Be aware - Actual buildplate temp lower than temp setting

Be aware that while the heated aluminum plate under the buildplate glass may reach the temperature you set, the actual temperature of the surface on which you print will be substantially lower. I set the buildplate temperature to 100C with the cover on the machine, and waited an hour for temps to co...
