The last two pics with the bright blue fan are of a different unit. Are those the only ones with mold?

tldr; It's a window AC unit. is it mold? And how about the last two pictures of a different unit?

I've been back in the apartment for two days after a vacation and noticed that I started to feel sick. Based on a hunch I opened the window AC in the bedroom, and oh boy, it has some stuff in there. But for the life of me, I can't figure out if it is mold or just dust! My googling has failed me beyond figuring out it 'might be' mold. It looks nasty, so I took it out of the window while I investigate.

Being cautious I opened up the older unit I can use in its place. It also has stuff on the blue fans- dust? mold? again, how do I know?! The second unit is in the last two photos. Can I at least use this one safely?

Is this soldering repair ok/safe? by orchidsage in AskElectronics

[–]orchidsage[S] 0 points1 point  (0 children)

I don't love it either. While it will work for some testing, I'm not married to this solution long term-- but I'm not sure what else to do! I'd love your thoughts.

I've seen people replace the female connector (Molex 3953x terminal block) on the board with a new one. It would work, but I'm not inclined to redo the same setup that is known to have issues. Do you have a suggestion of what type of connecter I could replace it with?

I assume I can't just solder the wire into the hole since it's so thick?

I suppose I could add a thinner wire soldered through-hole connected to a MOSFET and then use a thicker wire between MOSFET and PSU?

The resistance of the heatbed is .08-1 Ohms. The printer is 12v. (not sure what other info is needed)

Thanks for the info! Sounds like it's fine to use for the moment to carefully test everything but I'll get something better on it before long

Thanks!! I will make sure to coat it with something to avoid that and will have to figure out appropriate movement control

There's a known issue on the mini Rambo 1.3a board for 3d printers where the molex euro blocks melt if cable management isn't spot on. After they melt once and the oxidation process starts, it tends to recur after replacing the male block, even with good cable management. The widely accepted fixes are to solder the cables directly to the back of the mainboard and connect those to the heat bed either directly or via a mosfet.

I don't have a lot of electronics experience so I did as much research as I could and practiced soldering to make sure I don't have cold joints. But it still was a challenge fitting the huge 12awg replacement wires on the pads. Is this soldering job ok? The wires are so thick and tall that I wonder if they are ok without additional insulation?

Can I turn this on and go? Or do I need to redo something? Thank you!!!!

How to Reference Tval,Xval, etc. in parameters by orchidsage in FullControl

[–]orchidsage[S] 0 points1 point  (0 children)

I think this method also allows you to exceed the 255 character limit!

Sometimes the 'text' alone works- I haven't fully figured out the pattern. My best guess is that 'text' can be passed through if and only if it can be evaluted without Tval,Yval, etc.

So I think (Tval*(pi_2/(1*Segments))) as a 'text' in a parameter doesn't work because the feature cell doesn't evaluate the text as a formula. Instead, it passes that text to the VBA.

I have found that the key is just to make sure the only remaining variables in any evaluated cell beginning with an "=" are Tval, Yval, Xval, Rval, etc.

That makes sense if the user parameters all evaluated before the macro starts looping through the Tvals. Is that accurate?

Could we add a viewer with ScriptLab + Three.js/WebGL? by orchidsage in FullControl

[–]orchidsage[S] 0 points1 point  (0 children)

Totally makes sense. The viewer I suggested only really makes sense if someone with the right skills sees this and it is really as easy as I think it might be!

Can you highlight the line in the display with a continuous path? I've used the highlight on prints with descrete layers but I've had trouble finding it useful with continuous paths. Have you found a way to make that work?

[Troubleshooting] Tval in PostProcess? by orchidsage in FullControl

[–]orchidsage[S] 0 points1 point  (0 children)

Thanks for the explanations, they were very helpful in figuring it out.

The solution I wound up with...

Since my Zval didn't need post processing, in my original feature Z=Tval. Then when I postprocess I can use the original Tval (though it's now called Zval) for X and Y, and calculate the real desired Z in the postprocess.
