Re: Where the devil are the silicone hot-end covers?

Do you need to clean up the heating blocks and nozzles before fitting the socks? Mine have had some close encounters with failed prints, but I wouldn't say the build up is excessive.

Re: Ideamaker not properly aligning STL files

Thank you for your testing of this. I appreciate that. You're welcome Try with Auto-position after importing disabled under Edit -> Preferences -> Files. Vicky, just tried it and that works in IM. I didn't know that preference existed. However, a small downside is that now it doesn't automatically ...

Re: Ideamaker not properly aligning STL files

Hmmm, that's interesting. I put your stl's into IdeaMaker and I can see your misalignment problem. Putting the same parts into netfabb studio shows that they are aligned by default, but exporting each part as an stl still has them misaligned in IM. When I put these parts into Fusion 360, they are pr...

Dual extruder printing questions

I've had my N1 dual extruder for a couple of years, but have never needed to do any serious dual ex printing. Until this week, when I needed to print some small objects in 2 colours. The outcome was pretty good but I have a couple of questions... 1/ Can we have an improved prime/nozzle clean sequenc...

Re: Thick, Solid PLA Prints are Lifting

Most filament types will lift at the corners, when you try and print largish, solid objects, in my experience. Having square corners will exacerbate the situation, but rounded corners aren't a total cure. To stop warping/lifting you need to get really good first layer adhesion, so Z height and first...

Re: PETG on Pro2

I use PETG most of the time, I love it. I print straight onto a glass sheet at 260C & 80C. It sticks really well for printing and then releases easily when the bed cools below 30C. The bottom face comes out with a mirror-like finish.

Re: PVA transparent filament not detected by sensor.

Seriously Vicky? After the many months (or was it years?) in development, that is a rather shocking admission. I was going to order one, but if it has problems 'seeing' some of the clear filaments, then that is a serious shortcoming. Can you tell me which filaments it doesn't work with?

Re: Print Injection Mold

Try PETG. Parts are shinier, with lower friction than PLA. It prints easily and approaches the properties of nylon

Re: Readable template files

Another suggestion, for those of us that use IM for production as well as development, would be to make the slicing templates lockable. Then they would be protected against 'accidental' changes

Readable template files

Hi all, I am trying to document my print settings for production parts and I would like to just click a button and get a human-readable file with all the settings in the template. When I export a slicing template IM generates a BIN file but, of course, I can't read it. Does anyone know of a way to c...

Re: Successful ASA Settings

I have had success printing ASA directly onto glass. I need to add a little ASA slurry by put a few drops of acetone on the glass and rubbing a spoiled ASA print in it to make a thin layer. This is best done on cold glass. I find that ASA sticks pretty well and releases quite easily without force wh...

Re: Part Shifting On Glass Bed

It only seems to happen for me when I'm printing multiple items. I was printing a dozen or so items one day and the collision was so energetic that it pushed the glass bed out of the printer! Since then I print fewer items at a time and double up on the binder clips along the sides and front of the ...

Re: N2 Printer PolyFlex Filliment Problems

Does anyone have any advice for both print settings and removing the stuck filament? I have had the same problems you mention using flexible filament and I dare say everybody has who has tried it. Try printing slower, flexible filament doesn't like to be hurried. I print the first layer at 15mm/sec...

Re: Nozzle home position off the build plate

I have an N1, so there may be a difference in the priming routine on an N2, but I doubt it. I have the glass build plate positioned so that the nozzle is just over it by about 1mm. This is is easy to do as there is quite a lot of positional tolerance within the clips. In this position it's easy to s...

Re: Model release

Buildtak is okay, but has significant limitations. I have some PLA that sticks a bit too well to and found that a short woodworker's chisel is much better than the scraper supplied. I leave the glass in place in my N1 and very carefully ease the chisel under the corners/edges of the part. With patie...

Re: How to convert N1 to single nozzle, gcode control fans.

I upgraded to bondtech extruders which was really simple to do and a great improvement. Hi Tom I have an N1 dual and am considering the Bondtech Dual Direct upgrade, but all the instructions appear to be for the N2. The only real difference appears to be that the N1 doesn't have the cable chain. Di...

The key parameter is insulation, or "k" factor. The insulators I sell for Zortrax printers have a k factor of 0.48. And installation couldn't be much easier - a couple of silicone o-rings. Julia, I like your elegant design. Are they a universal fit or do you sell a version for Raise hoten...

Re: Buildtak

So, how is your experience with buildtak? I would say 'not bad', I would give it 6 or maybe a 7 out of 10. It's my surface of choice for PLA and TPU, mainly because I have 3 or 4 sheets of it lying around. With care I can get a sheet of Buiildtak to last 3 months. What I dislike is that the grip to...
