Re: Fuse keeps blowing

You must be reading the old part of the wiki. F2 supplies the logic only on early boards (versions prior to 1.2). Logic supply has been on F3 ever since.

Odds are he has a 1.3 board, so look at this page: http://reprap.org/wiki/Rambo_v1.3#Fuses

Realize most of us (including me) don't have that version of the board to look at. I can find pictures to look at, but pictures from your end would probably be very helpful. There were significant layout changes between 1.1b and 1.2 on, although it's functionally near-identical. Getting the thermist...

Re: SIMPLE CONNECTOR FOR HOTEND WIRING COMING SOON

Excuse the ignorance on the abbreviations SCL, SDA, INT? On an I2C bus, you have the Clock line (SCL) and the Data Line (SDA). INT is Initialize. Those 3 pins are only used on the Probe board from SeeMe, so if you are using your own hotend without the probe board, those 3 pins are open. Close. You ...

If by adjusting the wiring you meant that you reversed the B connector, that would explain the encoder knob causing resets.

Re: Well my Rambo melted

Not off-base. Things that are soldered then clamped are samll time-bombs. A soldered wire under a screw clamp will tighten up fine, but then the soft solder under pressure flows over time, allowing the wire to spread out and the clamp to become loose. Loose connections produce heat. Heat melts plast...

Re: Determining unknown nozzle bore size.

It won't be smaller than 1.0 mm, if that's the hole size you drilled, so it follows that it's larger by some tiny amount. See if a 1.1mm bit* will hand-fit in the hole. If not, it's still somewhere between 1.0mm and 1.1mm, and that's probably the best measuring tool you're likely to have handy. But ...

Yes, you could, and it would probably work. It'll look ugly, of course, and it complicates future disassembly without some kind of connector.

99% of the time you're talking to the peanut gallery in the forums, most of which don't know anything about the H1.

Unplug the HE280's connector and try again. If the rest of the system now works, that says there's a wiring issue with the upgrade. Check everything, including whether the harness came correctly wired from SeeMeCNC. On the other hand, if the rest of the system isn't working, figure out why before yo...
