Got the board to work. Turned out to be a bad solder from the factory. I just separated the two posts and voila. Now I need to figure out why temps are reading DEF. Everything is brand new, so it has to be a connection of sorts. Thermistors were just replaced.....

The fan for the rambo does turn on. I am pretty familiar with this board at this point and have many of the little fuses on hand (bought a roll of them) just in case I'll check some more around the board with the ohm meter. Thanks.

Thanks Cale. I tested the power input and it checks out fine. I replace all the fuses just to see if maybe it would show some sign of life, but still nothing. I'm baffled at this point and considering selling it if I can't fix it.

Similar problem here as well. No led lights on board. Fan under it turns on and the hot end lights up. This is a brand new hot end with a brand spankin new whip and RAMBo from Ultimachine. I tested the power coming into the board and it's a solid 12.4v, but doesn't seem to want to go any farther ...

Awesome! I finally contributed something glad that little trick worked for you!

Got a new rambo and installed it, flashed the newest firmware and fired her right up. Immediately the bed temp goes Def to -50, no was at 20. Then the lcd just goes black. I snapped a pic of the board wiring before I replaced it and reinstalled it according to my picture and the other online at ...

Xenocrates, great suggestions as always! I did meet a guy that has a formlab printer, i'll reach out to him. Thanks!!!

What molding machine are you using and what are you injecting? How many parts do you want to get from one mold? I've retired my SLA printer for another year. The software is still not up to snuff and I don't have a compelling need for the technology to deal with it. I'm buying a small benchtop mold ...

Is anyone out there familiar with making a 3d printed mold for an injection mold machine? I need to make one for a small product about the size od a small goldfish. I can pay! Thanks!

Well, it looks like I won't be getting the mini :-) I'll just go with the stock version of the RAMBo that came with it to save time and so I can resume my work making prototypes. I love 3d printing and all, but I got into it to make prototypes and just need to have the machine working. I am learning ...

NOT rude at all!!! I'll reach out to Ultimachine and see what they can do/recommend. I'm considering that mini rambo for the $85. Will my current wiring arrangement fit the mini the way it does the stock Rambo board on the V3? Hope I worded that right :-) You answered so many questions and took a ...

You Xeno! Can you recommend a cheap replacement board? Found the RAMBO on Amazon for $180 and the mini for $140. Is the mini about the same thing?

Juicy, I had that issue and it was a loose connection in the whip connector. Have you looked there?

Where do you get the duet board? I'mlooking for something more affordable than the Rambo ($180). What other boards will work with the V3? Thanks and I look forward to hearing about your build! I have a Duet .85 board, its the board right before the Wifi and I have the expansion board and ...

On the face of it, I'd suspect power sag - does it happen when only heating the hot end and not the bed, or only when heating the hot end and the bed? g. Geneb, we've already gone over the bed+ hotend or just hotend thing. It is a hotend issue, as apparently the bed doesn't matter. I might try ...

On the face of it, I'd suspect power sag - does it happen when only heating the hot end and not the bed, or only when heating the hot end and the bed? Also, on a bad-decision scale from "Hey y'all, watch this!" to "Let's start a land war in Asia!", cussing at a moderator in public is essentially ...

I submitted a ticket to inform them of the issue, but otherwise I think I've got that voltage issue fixed. Upcoming upgrades to order soon (some on backorder for a week or two): Duet Wifi board PanelDue screen E3D V6 hot end and nozzles BerdAir cooling system Possibly look into various TrickLaser ...

Thanks Xeno. Cross posted as I was in panic mode trying to get an order out and needed a part quickly. I just replaced the he280 in its entirety with a brand new, pre-assembled unit from seemecnc and it still resets when I turn the heat/fan on. Il submit a ticket for this to seeme and hope for the ...

Thanks. I just received my new he280 from seeme and installed. Same issue! Has to be the Rambo at this point, I think Led 4 lights up red, then the lcd shuts down and restarts when turning on either the heat or fans.

As many times as it takes to get an answer. Got a problem with that? Do me a favor and don't comment on my questions anymore as all you have to say is rude shit.

Sorry, I should've been more clear. I cannot get the stock HE280. What other hot end will work? Any other accelerometers work?

You got it

Since the only "cash" I have is in the form of amazon store credit and seemecnc doesn't accept amazon payments any longer, is there another hot end that works well with the V3? I currently have the HE280 and love it, but Amazon doesn't have it, so I am considering a different hot end. E3D? My ...
