I was wrong, I changed the MINTEMP to zero, just so the printer would stop shutting down, and I could read the temperature signal pronterface was receiving. The extruder is showing 0.3 degrees, and the bed temp is still sitting at 3-5 degrees. So...thermistor wires outside of terminals are reading fine approx 102K on each. Seeing 4.5K across both the e-trm and b-trm pins with the thermistors plby l51r8 - Reprappers
And I checked the back of the board for wire pieces or abnormalities, it looked like there was a lot of debris around the thermistor wires, I cleaned it off, unfortunately no change.by l51r8 - Reprappers
Thanks for the help. When I measure the pins I see 4.5K on both the bed and extruder. I know that's pretty close to the 4.7K pull up resistors, I don't know what to make of that?by l51r8 - Reprappers
Update: The extruder thermistor actually seems to be working fine, when I disconnect and reconnect, the extruder temperature shows normal temperature for a second or two berfore the error occurs ands turns it to zero. So it's the bed thermistor that's now the problem. Anyone have any suggestions???by l51r8 - Reprappers
My printer had been running fine, except for a slow filament leak at the hotend. While attempting to tighten the heater block around the nozzle, one end of the thermistor wire slid out of the not-so-crimped connector. The thermistor then shorted out, and blew. I changed out the thermistor, and changed the config.h file for the new thermistor type. But I'm still getting this error in pronterfaceby l51r8 - Reprappers
Thank you, if you have not already sent that part, don't worry about it. I wrapped some tape around it, and there's no way it will come off now!by l51r8 - FoldaRap
Also, the y-motor bracket arrived broken. I had glued it back together, but now that the belt is attatched, it is starting to come unglued. It definitely will not stay attatched, I very much doubt it would even last long enough to print a new part. Would it be possible to get a new piece please? Thank you, Debbieby l51r8 - FoldaRap
Just putting it together right now. Watching the video for "wiring everything to the board" and it looks like you plugged the fans into the Aux V I/O, rather than the fan +/-, is this correct?by l51r8 - FoldaRap
This is great information, thank you! Very nice to see such a low working average I was definitely going to try using the blue tape, and skipping the heated bed when longer off-grid prints are needed. Also, I am going to try feeding it direct 12V DC, should save some more energy not using the AC inverter. I'm thinking I should be able to get 6+ hours printing time out of it...much longer than uby l51r8 - FoldaRap
Thank you so much. Got it up and running!by l51r8 - General
Sorry, this comp is a little buggy, and sent my post early! If someone could please tell me the detailed steps to get the printer running on linux, or at least point me toward a COMPLETE set up guide, I would be forever grateful. And again...I know NOTHING about linux! Thanks in advance, Debby l51r8 - General
Hi All, I'm trying to control a Mendel w/ Gen6 electronics with a Efika MX Smartbook (arm cortex a8) running an Ubuntu/maverick 10.10 based distro. I've had it running fine on my windows laptop using Repsnapper. But I am completely lost when it comes to Linux! I had no luck running repsnapper, reprap host, or repetier! I have managed to successfully install Pronterface and Slicr. But I cannotby l51r8 - General
Thanks so much! This is very helpful, and just in time, all of my parts are starting to arrive. I can't wait till your printer arrives. Cheers, and happy buildingby l51r8 - FoldaRap
That would be great! We are ordering your "Do-it-yourself" kit today, but I won't be able to start designing the rest of the circuit until I have a solid number for power consumption. I will be documenting the build, and keeping the entire system as low cost as possible, with BOM and build instructions. Hope you like it!by l51r8 - FoldaRap
I wonder if the project you're refering to was ours as well? It had two panels and four batteries. That could run the printer for 4 days on one charge. But we have decided to just power it for the one day to greatly reduce the size of battery required. It will all fit into a small suitcase when it is done, thanks in a big way to your printer! The recumbent bike can produce about 75-100W, so it wby l51r8 - FoldaRap
Great work! And thanks for doing such an amazing job of documenting the build process. I stumbled upon your machine, while doing research to make a portable, solar powered printer. With my project being open source appropriate technology your printer would be a perfect fit. I have already mentioned and linked your work on the project page. I was wondering if you've taken a power consumption reby l51r8 - FoldaRap
