Re: STL import on dome shape, totally wrong size

Make sure that you export the part with sizes in mm.
Your problem seems to arise from the fact that it was exported in inches instead of mm.

Anyway, find attached your file corrected to mm.

Re: Problem with removeming surface filament

Did you change software versions between then and now?
The printing temps where changed at some point and that can cause your problems.

Re: A few issues

WInbo seems to be a pretty straight up company, other forums dont have users complaining, but consensus is the ABS needs 245 degree even though advertised to work from 210-260.. the filament is that cheap that it warrants trying to get the temp right.. Cheap filament and cheap temp mod: add a 5.6oh...

Re: A few issues

Can someone suggest the simplist plug and play one that will do 245 degrees please Simplest way is to add a resistor in series with the thermistor. It is about 1.8ohm/5C. Latest software uses 260C for printing ABS, so 15C less is 3x1.8ohm = about 5.4ohm resistor needed. [..] but I'm willing to expe...

Re: A few issues

That perfboard in the last picture looks like it has seen at least 50-60 prints of different sizes on it. Anyway, you will need a temp mod to print other types of ABS or PLA filament. Until you get there, source some original UP filament to really see the quality of the printer (great printer). 2-3 ...

Re: Suggestion: "Turn off printer after print completed" opt

The printer is always on or let me put it better, the motherboard is always on when the main power button is active. The soft button with red light on the front is only to give you the feeling that you start it . I think it would suffice to have an option to park the print bed then turn off power to...

Re: Replaced my extruder completely

Congrats, the new assembly looks slick. The stepper, being bigger, support a lot more current, hence the lower temperatures. Having the same dimension on the toothed pulley is a big plus. From pictures it looks like an Mbot/Flashforge extruder/nozzle assembly. Please take care of the temperature, fr...

Re: Bad impression of a solid wall.

Looks like the slicer (UP software) decided that it can not fill it as requested, with diagonal lines and high infill per your screenshots, which is normal.

You could try selecting full 100% infill and report back.

Re: This happened last night

The printer vibrates on high speed moves around sharp angles and produces ripples that resemble the movement around that corner. It is perfectly normal on high speed. They go away if you select high quality and the printer moves slower. If you also see them on slow prints then there is something loo...

Re: Up mini extruder stepper specifications

From my limited knowledge about steppers, I was under the impression that NEMA numbers refer to the phisical dimensions of a stepper motor (square size), the difference between power rating on the same NEMA size being compensated by its length. Higher power = higher torque = longer motor = heavier. ...

The shaft of the stepper is still made in stainless steel and the temperature is also creeping through it and through the whole stepper motor. Nice one, jeeplvr. I wonde...

Re: Mini wind barrier and stepper motor platform mod

Watching you closely for news. I just burnt my finger when I touched the stepper motor after a 3h print. Anything to get down that temp would help (besides opening enclosure). Are they really supposed to run at over 50-60C? Maybe current through them is a little too much or even more than needed? An...

Re: Two connectors for fans on printhead?

It sometimes takes 3-4-5 quick clicks on a mini to get the light started... keep that in mind. The LEDs don't draw more than 20mA while a fan usually goes above 100mA while working and much more at the moment it starts. I don't recommend you to connect the fan there. It should be better to use a mor...

Re: Two connectors for fans on printhead?

D3rax, the second connector is used for the 3 LED strip on a Up! Mini.
Can't advise on a fan connecting to it though.
