Welcome to the SeeMeCNC Community

Ended up just going to radio shack and getting some of these:

They slip right onto the pin in the connector.

The ones I am looking for are the ones at the top of the board (they have screws to hold the wires in place). At least I am pretty sure that is where the hotend fan is supposed to be plugged into.

That's my plan! My fan should be here later today too. However, I am looking at my RAMBO and realized I dont have the connector for connecting the fan to the input on the board. Is there a connector that can be easily had from Radioshack (or some other local source)? Or do I need to go the Mouser ...

I don't think it is a communication error. I was able to use the manual controls for heating the hotend, extruding/retracting, and sent the printer home with G28. My guess is that the automotive fuse is blown. From what I have read on the Wiki, it is the fuse that controls the heated bed. I'm headed ...

So I have been printing calibration objects all day. I just now went to print yet another calibration cube and the RAMBO board won't run the G code. The bed wont heat up, neither will the hotend. There is a yellow blinking light on the RAMBO board. It is the led labeled "TX" immediately behind the ...

So I finally got my printer printing!! HELL YEA!! Now I am trying to get the calibration cube dialed in so I can get perfect prints. Here's some pictures of what I got on my first print: [img]http://i.imgur.com/RRrkyXi.jpg[/img] [img]http://i.imgur.com/6c8Bsmm.jpg[/img] [img]http://i.imgur.com ...

I got it working. Just had to change "#define EXT0_INVERSE false" to "true".

I think I just figured it out (crosses-fingers). The extruder is retracting instead of extruding. Now that I think about it, it makes sense. I use the "Retract" button to extrude manually. (it was assembled by the previous owner and that is how he told me to manually extrude.) What would be the best ...

Yup. Everything moves around and it acts like it is printing, but nothing will come out. I've been able to manually extrude filament immediately prior to running the code for the calibration cube, but when I run the G code, nothing comes out.

I just sliced the calibration cube in Slic3r and nothing happened. I didn't change any of the Slic3r settings though.

Im using Slic3r in Repetier for slicing. I'll set up Skeinforge and give it a try.

I don't have the LCD/sd card reader for the printer (bought it used and didn't come with it), so it's kinda hard to print from an SD card... Any other suggestions?

Nope. Dry Run is turned off.

Yea, the bolt turns (I put a dot of sharpie on the bolt just to make sure). It even extrudes and retracts when I use the manual controls.

FWIW, I am following the calibration steps in the Assembly Guide.

So I got my Rostock MAX all calibrated and everything, and now I am trying to print the calibration cube. I was able to extrude filament out of the hotend manually, but when I go to print, nothing comes out. my temps are : Bed: 60 C Hotend: 190 C I am printing with PLA. Anyone know how to fix this?
