@lo-fi Here's my print of your redesign. I'm really happy with it. I followed your settings and it printed great. A little sanding and trimming was required to get the halves to fit but they fit well. I used pla on the housing and pla+ for the idler. Once I redo the
print head and x axis on my printer, this is going on there over the top of an lgx lite on a custom mount. Thank you for putting forth the effort and making your design public

@phaedrux

I was able to contact Bondtech and they confirmed the lgx lite is designed for properly
sized filament. My issue is I received a lot of filament when I bought my printer and it's at least two years old now. Even though most of it is still sealed, there are some rolls that have been opened that are getting brittle and have decreased some in diameter.

I was told for undersized filament, I could use the TPU setting on the extruder. This has worked ok so far without the motor getting hot or any other issues. The lgx lite is pretty well built. I thought at first my issue was cold extrusion. I installed a rapido hotend and even though I pid tuned it, I'm still not sure if I have the right settings in config.g for that hotend. My old hotend was a v6,

Overall, I'm happy with the lgx lite. My only wishlist item would be a "middle of the road" setting between the solid and tpu settings for when you don't have optimal or consistent sized filament.

It was the sd card. I was lucky I had a config backed up on my tablet that was fairly recent. I did have to redo everything else though, macros, firmware and so on. I'm going to make a backup sd card as soon as I get everything tuned right.

Thanks again,

@zapta For those who may be curious how this turned out, I was not able to discern what type of component I needed to replace. I did the manual check
for zener diodes and that test did not show a zener diode. The T7 tester I bought for this is also confused. It has shown IGBT, PD mos, dual diodes and cross connected diodes. It's not consistent at all with this one component. I asked a person I know that use to repair tv's and he said it could be a custom part made just for that company. This might explain why the markings don't
show up anywhere. Anyway, I found my receipt and the company replaced the faulty unit. Thanks to everyone that chimed in, I promise not to burden the forum with this sort of thing in the future.

@zapta I have nothing else to do today so this will be my goal. I really hope after all the trouble, it's not something else wrong with the camera entirely lol.
Thanks for the help.

@dc42 Its just the inconsistency of the tester I have. I found on one of the databases
the RDt component is listed as a dual zener diode but my tester does not show it in a
configuration I can find to purchase. This confuses me. I contacted the company, they won't help other than replace the unit with proof of purchase and evidence of the corrosion. Well, I already removed the corrosion in my first repair attempt. The proof of purchase I doubt I can find sadly.

@moth4017 Thank you! That fills in the blank for the mosfet, now I have to figure out
the other component. I may reach out to the company for a schematic. My chances are slim
but its worth a try. I can't find a dual zener diode with that configuration. It could be my new tester is lying to me and it's something completely different.

Thanks again,

@zapta So it took longer than expected to get the tester but here's what I got.
I don't think the tester is very good with zener diodes. It has 3 terminals just for those but if you connect a standard diode there and test, it shows it as a zener as well. With that said, I think RDTE could be a duel zener...I just don't know how to tell. Finding suitable replacements is where I need help.

@zapta I think I can make contact with what's left of the terminals. They're broke off flush
but they are there. I ordered the T7 tester, it should be here next week. I hope the tester will take the guess work out of this project. I'll report back when I get the results.

@dc42 Thanks everyone for the help. I wasn't sure if this would get much attention since it is a bit off topic. Preventing the burning down of one's house is a noble endeavor. I went through this with my duet 2 wifi board as it was purchased used and abused. Multiple fried components, things didn't work. I was able to fully restore the board with the help of reading this forum.

I was wondering if an LCR meter would be of any help here? I don't know the scope of what components those meters will identify or identify correctly. I'm sure caps, resistors, diodes and the usual stuff but what about zeners and more complex fets and things?

I may order one if I can find a way to get leads attached to the components
to test them. Missing one leg on each isn't going to help matters....maybe the
use of a needle as a probe?

@moth4017 They both had 3 legs, the corrosion removed the third. I've looked
all over for that logo and the markings and I can't find anything definitive. I'm seeing this
more lately where i'm trying to fix a device but the markings on components dont lead anywhere. If I could find a broken one of these cameras on ebay, I might go that route unless someone has some insight here. Thanks for your interest!

I know there's some electronics wizards here, I need a hand. I had an incident
a few weeks ago where the solder joints failed on the mosfet board that runs my build plate. This could have caused a fire. I want to use a solar powered automotive back up camera as a monitoring device for my printer. The one I have quit working since the last time it was used. Corrosion has ruined two components on its circuit board and I can't find info on these anywhere.

Here's a pic of the components. They read RDTE and E5UB. Any help finding what these are or suitable substitute components will be appreciated greatly.
