Re: Smoothie on a breadbaord using OM13054
Sounds like you're saying that what Arthur talks about are more pipe dreams than anything, did I miss something? I am new to this so I'm assuming I did. Do you think that the production Smoothieboards...

I am not sure what would be involved in this but would it be possible to build in a USB flash drive reader as opposed to an SD Card reader? I just think it would be more practical and a lot more...

The 4 models with coil resistance of 3, 2, 3, and 1,25ohms are ok. The rest have 20-30-40 ohms coil resistance which means those wont work too well with 12v psu. Use a model with 3 or 2 ohms, i would...

As far as i know the arduino acts as an usb slave as well as the flash drive does. Communication between 2 slave devices is not possible. So you would need additional hardware like this to let the...

For about the same money as a sd card connector you can get a 16Mbit serial flash memory. Would that be enough to store reasonably sized files? My printer is not finished yet so I do not have a clue...

As painful as the PCB layout was to do in KiCAD, it pales next to the frustration caused when trying to extract decent manufacturing data from the package. Much of this is not the fault of KiCAD...

You can try this tutorial its an old page (initial pictures are gen 3), but should work if you have a laser printer that can transfer (not all work good) and you find a paper that also works (again...

It works!!! I had my endstops wired into the RAMPS board incorrectly. I had pin 4 plugged into Ground (-), and pin 1 plugged into Signal (S). If my endstops were wired Normally Closed the connection...

Thanks Scuba. I think that would be something cool to look into. The host board is pretty cheap. I would just rather copy files to a USB drive and plug it into the printer as opposed to an SD card...

View ArticleRe: Signs of a failing Thermistor?
Check that you haven't got a resistance between the hot end and the thermistor somehow. Shorts are bad, but a high resistance (say 10K-10Mohm) is even harder to debug. Unfortunately many glues...
View ArticleRe: Signs of a failing Thermistor?
hi I'm not sure what you mean with the resistor being between the thermos tor and the hot end. I've connected them both to the RAMPS 1.4 board directly haven't soldered on any resistor, so unless the...
View ArticleRe: Signs of a failing Thermistor?
Not an actual resistor. Some high-temp glues can act like a resistor if they are in contact with the metal leads of either the hot end heater or the thermistor. Use a multimeter, and measure the...
