  1. Greetings, We recently published a complete documentary of the process I use to transform a 3D printed PLA part to a machine ready aluminum alloy casting: http://www.thingiverse.com/thing:82176 Please let me know if you have any questions!
  2. Thanks magicxman, that did the trick! I am using the onboard MOSFET so I enabled PIDTEMPBED.
  3. Thanks Daid. I just rebuilt the firmware and still the same issue. Any ideas?
  4. So my heated bed has been working great: http://www.thingiverse.com/thing:30655 But I just hooked up an Ulticontroller i just got, and enabled the Ulticontroller using Daid's excellent firmware builder at: http://daid.eu/~daid/marlin_build/ And the heated bed no longer works (It was still configured for the heated bed). If I upload firmware without the Ulticontroller enabled the heated bed works. Any suggestions would be greatly appreciated!
  5. Hi, I just received my replacement Ultimaker RAMPS board. It is version 1.5.7. Before I build custom firmware using Daid's awesome firmware builder at: http://daid.eu/~daid/marlin_build/ I just wanted to make sure it will be compatible with the 1.5.7 version board. Thanks!
  6. Greetings, Can anyone please tell me how to what g-code I would use to set the 2nd extruder temperature? Thanks!
  7. Can anyone please tell me what is the G-Code to set the temp on extruder 2?
  8. Is it possible to configure the firmware to use Heater 2 for the heated bed? It is not immediately obvious if I can configure the firmware to do this with http://daid.eu/~daid/marlin_build/
  9. I have the 1.5.6 board with 50amp mosfets. The mosfet is STP55NF06L which I ordered from Mouser for $1.40. Meanwhile, I snagged the mosfet from heater 2 since I currently only use single extrusion, and, even after commanding the heated build platform off it is stuck on. I reset everything, and still on. Any ideas?
  10. Greetings, I have been using a heated build platform without issue for PLA running 65C for the first layer and 50C for the print. I just tried printing ABS and set the bed to 70C. Shortly after it reached 70C I noticed smoke coming from under the Ultimaker. It was Mosfet for the heated build platform that was smoking. Can anyone tell me the specs for a replacement mosfet? A Mouse part number would be great! Commanding the build platform to heat no longer turns the heater on. I am not sure, but I think the mother board fan might have caused the problem. I just noticed that the fan turns on when I first power it up, but after a minute or so the fan turns off. I think I will hook the fan up to an external power supply, but seems strange. Anyone have any idea about it turning off? Thanks!
  11. Greetings, I successfully milled an aluminum bed this weekend on my CNC machine for my Ultimaker. I posted a parts list, instructions and a bed drawing for milling here: http://www.thingiverse.com/thing:30655 I wanted to use the stock bed mount and springs, and it works great! Printing right now sans blue tape! Please let me know if you have any questions.
  12. Good points, but from everything I read on the subject, threading the Bowden has permanently resolved the issue for many folks who were plagued with the issue.
  13. Thanks Daid! I really wish they would have threaded the Bowden. Seems like the best solution to the Bowden moving up problem to me.
  14. I understand completely. I didn't develop the iPad Photo App of the Year (named by Apple) by creating an interface with 10,000 options. Its power is in its' simplicity. That said, there are some very useful things that could be added carefully without taking over the primary focus: to print!
