Re: Thinking about 3d printer

Greg
Are you able to see if any files have actually been saved on the SD card on your pc?. I have an Ender3 V2 printer and the supplied micro SD card was not the best despite numerous reformats!.

Re: Thinking about 3d printer

I've ordered plenty of pla Beware, once they are open, they start to suck moisture and printing will get harder (bubbles, adhesion issues potentially). Don't open all at once (if different colors) AND don't let the filament end fly off loose. I personally found that out when nearly at the end of a ...

Re: Leitz LK condenser filter drawer system

I 3d printed some holders like you show and have had no problems at all with darkfield o...

Re: Epi illumination without Dichroic mirror maybe?

Many thanks for the tips Greg!. I don't pretend for one minute that this setup will replace a Dichroic mirror but it does give some useable illumination and fortunately I'm not playing with a $1000 scope 😁.

Hi guys
Like Michael suggested and also suggested by a friend that you can't really get true optical extinction with a circular pol filter and a linear one but two linears are needed, just waiting for one !

Re: [HELP] - Hayear Cameras Setup & Software

Forgot to mention that I had to use a 0.5x reduction lens with the Hayear to get similar fov but I don't think that affected anything. Hayear is probably fine for live hdmi displays on a monitor but not when using with a pc.
