Mintemp- as a safety measure, the Marlin firmware shuts down the printer if the hotend thermistor reads Zero (0) degrees. It assumes the thermistor has failed and shuts the power down, to avoid a runaway heating issue.

Your thermistor is not working right, and since it's reading zero its probably not wired/connected right. when you turn the printer on and poll the temperature in pronterface, it should show room temperature for both bed and hotend, 18 to 24 degrees or so.

I'm getting temperature readings on ex0 and bed. Apparently pronterface is trying to get a temperature reading for ex1(which I don't have a second extruder) when I connect the thermistor from the bed to the ex1 slot the error goes away.

So my question is how do I set pronterface or firmware to only work with ex0?

i've dropped my sdcard like 6 times because of access to the card being so restricted...

Yeah, had the same issue. I'm thinking if I get slightly longer LCD cables (the ones included were a pretty tight fit to begin with). I can print a new LCD mount that has the screen against the left side bracket that way the card can be accessed from the side like on the other screens.

Has anyone contacted Colin on these firmware issues? Yes, there have been problems in the past with 10-inch printers shipping with 8-inch firmware. One would have thought similar issues wouldn't occur with the new RAMBO board, but... Although their boards may not ship with the right firmware, and the build guide and videos don't always point to the right firmware download, Colin has always been able to provide people with a link to the right firmware source for their printer - having to search out additional libraries shouldn't be necessary. And the Arduino IDE already comes with an uploader called Avrdude. Uploading is built into the IDE. As long as you have Arduino configured for the right type of AVR processor board, you shouldn't need to go off looking for a third party upload tool. At least I'd be surprised at having to.

EDIT: Well, yeah, getting the USB driver set up is almost always a problem spot. I'll grant you that.

I emailed him today about it. He said that the build guide specifically states the ramps board comes preflashed, but doesn't mention either way about the rambo. He confirmed the rambo needs to be flashed before use. I responded with the manual looks like it originally included ramps only and the others were added aftwards and that it leads one to assume it comes preflashed. Since only the rambo is sold in the kit, I think some more information regarding the rambo should be added. The link to the firmware is in the build guide though. I think it should clearly state the rambo needs to be flashed and add a link to the arduino software. The only mention of Arduino software is in the ramps zip file and its so old(0023 I think?), it doesn't even support the INO file included in the rambo source.

Also, thinks for the heads up regarding the arduino software. I really have no knowledge of arduino and other than flashing my rambo, have never touched it in my life.

BTW - the general opinion on Arduino IDE versions is that 1.0.5 is where it's at, not the latest IDE available from Arduino. I think there have been a few people using the latest IDE (and any updated math libraries etc. that go with it), but the general recommendation is to stick with 1.0.5 for Marlin for now as a stable, proven version to work with.

Yikes, I didn't think the SD card location could get worse but apparently it has!

Another thing to think about is getting a Raspberry Pi and running an Octoprint server. You can send files through your internet browser through wifi to the raspberry pi's sd card and then the pi just hooks in to the usb port of your ramps board. It's one of the best and most plug and play upgrades you can make on your printer! You could likely buy everything you need for the same price of longer LCD cables and you time of upgrading the mounts.

I hated having to pop that sd card in and out every time I needed to make a change and I haven't done it since. I'm actually running mine with the LCD detached right now!

Yeah thats a soon to be implemented upgrade for me.

I went straight for the geared heart just to show off to my wife :-D

But after this im going to swap to abs get another cold end printed as well as the abl stuff.

btw does anyone have a suggestion for an extruder version i should print.... there are several to choose from. I do want a wades style direct drive like whats on it. just curious if anyone has a specific design they think is better than others.
