Should I consider that my .35mm nozzle generates .35 thread and it means that it's just .5mm I have to add to my 1mm walls go make them solid?

Actually I had to lower z-tab to solve scratching issue. This also solved height problem. And regarding coming of the print bed, support guys recommended to use hair spray! It works!

Now few more stupid questions smile

1. Is any kapton suitable for z-stage? I found and ordered one from HK (100ft 20cm width).
2. Printed item bends in height toward X-axis zero coordinate. It's about 0.5 mm for 1cm of height. How to fix it?
3. I'm trying to bring box with thin walls (1mm in project). They become very fragile and layer are laminated on apply tension. Is there any solution for such kind of printing?

Thank you again for help!

P.S. and yes, electronic are heated up. BUT when I open window to cool them down, it also cools down print bed sad I think, I have to install cooler on electronic board...

Sound like the Z isn't moving every time.  This can happen if the electronics get too hot. Try blowing a fan at the back of the printer.  Also check that the voltage going to the Z motor is correct.   There are instructions for that on the troubleshooting page at the Solidoodle site.

This is a great idea. If you have an IR thermometer, take a readying to see if we can confirm the higher than normal temperature.

My toy has jus arrived and I'm trying to do some prints... and, unfourtunetely, have some problems:

1. Resulting print height is not as designed. I have 3mm height model, but it prints about 2.4mm.
2. Extruder scratches previous layer time to time and white filling all printer is flattering
3. Printed part time to time comes off the print bed (may be one corner, may be other). And it becomes bended when finished printing.

What I've done:
1. Calibrated z-stage (first layer now a little bit flat)
2. Leveled z-stage (with 3 screwses on it).

What else can I do? I would realy appreciate any ideas and guidlines!
