Make sure your usb cable is away from power and stepper cables. Try a different cable if you have another. Check to see if your Firewall / Security software has sandboxed arduino in some way. Try the hold reset trick 10 times in a row, it should work at least once.by slymike - Controllers
It might help if the baud rate in control panel matches that of your firmware. That's helped me before. Also double check your connections, and if your using more than 1 usb serial lead/ device, check your connected to the right one.by slymike - Controllers
Ok, I'm not familiar with your board but check to see if it has a jumper labled "enable reset", or something similar Also you can get around this problem by holding the reset button whilst it compiles and release the button as soon as the IDE displays something like "done compliling, file size xxx" in the info box.by slymike - Controllers
It would be nice if anyone who downloads the Eagle files, would leave a reply so I can gauge the interest in this PCB. Also, if anyone has any suggestions for improvements I'm willing to re-spin it to add new functions. I.E. onboard FET, fuse, whatever. Thanks.by slymike - Controllers
BTW You need to find out what firmware you have loaded on your board and download a copy to your PC. Probably best to check the site that sold it to you. The Arduino IDE only lets you upload new code to your board, you can't download it to the IDE from your controller board and edit it again.by slymike - Controllers
Does you arduino folder and IDE look anything like the attached picture?by slymike - Controllers
If you can find a linux distro that will run on it, your half way there. In theory.by slymike - Controllers

What firmware are you running?by slymike - Controllers
In the 'Electronics' section of the wiki (amungst other places) you will find links to various firmwares, in each (in most cases) will be a folder named 'sangulino' with instructions on how to add support to the Arduino IDE. Or maybe you will come across a folder named '1_arduino-0018-incl_sanguino' - if you have this your ready to go! ( I got mine from the GEN6 software download). As far as bloby slymike - Controllers
OK peeps, tried the mod listed above and......it doesn't work! Pin 40 on the 644 chip seems to go HIGH when the serial line is active so once you connect to your PC, the heater will turn on. Pin 37 is the only choice for analog in and works fine. I decided to make use of the programming header as it does nothing when your running your printer. Physical pins on the 644:- 2,3,4 are in high impeby slymike - Controllers
The pins for the DIP and surface mount IC have a different layout, So the above IS NOT correct for a GEN6 board as it has the 44pin SMT IC fitted. Check the Atmel 644p data sheet and use the port numbers as reference.by slymike - Sanguino(lolu)
Attached is the Eagle PCB file for my Mendel Heatbed PCB. its (nearly) the same dimensions as the Aluminium bed on a Mendel. It requires some knowledge of PCB fabrication / sourcing, as well as basic tools, drill etc. Plus some extra parts, nuts, bolts, washers and a hand full of components. Its a sandwich design using a 6mm MDF sheet as a bottom insulator and the original aluminium bed on topby slymike - Controllers
If your etching a PCB and putting it in a box why not cut the xbox plug off and connect the wires with .2" screwdown connectors or solder them directly to some fat tracks and then deal with the 4 remaining wires (GND, +12V, +5V, PWR ON) through a nice sturdy plug / socket combo going to your reprap. Also your gonna have trouble even with a double sided pcb as you can only solder the bottom layerby slymike - Controllers
Hi guys, I'm new to 3D printing, I am just setting up my first Mendal that I brought as an unfinished kit a couple of weeks ago. I'm running a GEN6 controller, so no integrated heat bed controller but I do have a V2.2 Extruder controller (http://www.thingiverse.com/thing:436), which is basically an Arduino with all the goodies strapped on to control heaters and read temps, control servos, driveby slymike - Controllers
