  1. Stu_le_brew What did you search on AliExpress to find these parts, I need to order the Hot end Isolator coupler. Or do you have a link to the supplier. Thank you,
  2. In stead of messing with the code of Marlin, I started to swap out resistors 4.7k ohm was what I have been using this whole time. I tried 10k with no better results. With each resistor I recompiled the look up table with the Python script from Rep Rap 22k ohm works ! It starts off around ~ -20 only 2 less then the last value in the table {1008, -22} 47k ohm works as well but it starts around -44 Testing the 22k ohm resistor, Using my fingers to heat up the resistor It only returns a result of ~9c which means I should be dead. But I don't care, its working with out messing wi

  4. Help! Anyone having issues using the Heated bed MOSFET on the Ultimaker Shield ? Here is my setup for Marlin: http://daid.eu/~daid/marlin_build ... stepsE=800 I can see that the thermistor is working in the PrintRun. I can connect to the machine and and use a heat gun on the themistor to get a proper temperature reading. Next step is setting the Bed Temp to 60 Here is some of the read out with the Monitor Print box checked. ok T:35.7 /0.0 B:3.0 /3.0 @:0 ok T:35.8 /0.0 B:3.0 /3.0 @:0 ok T:35.2 /0.0 B:66.6 /3.0 @:0 (Applying Heat gun) ok T:35.2 /0.0 B:78.8 /3.0 @:0 ok T:3
  5. http://daid.eu/~daid/marlin_build/ This page has no options to enable the heater or the heated bed. It only allows you specify the sensor, not the heater its self. I thought I had dead pins on my Arduino so I ordered a new one. But it turns out that its a software issue. In the Configuration.h of the marlin firmware I have it already set #define TEMP_SENSOR_0 -1 #define TEMP_SENSOR_1 6 #define TEMP_SENSOR_2 0 #define TEMP_SENSOR_BED 6 But the hot_bed and heater 1 still do not work. only heater0 works. (the hot end heater)
  6. Ok I uploaded some basic code to the Arduino 2560, AND the 2 pins that I thought were dead are not. So I am missing something to enable the Heated bed, and the Heater 2 transistors. Anyone have an idea where I would go to enable these in the Marlin firmware. const int lowestPin = 3; const int highestPin = 4; void setup() { // set pins 2 through 13 as outputs: for (int thisPin =lowestPin; thisPin <= highestPin; thisPin++) { pinMode(thisPin, OUTPUT); } } void loop() { // iterate over the pins: for (int thisPin =lowestPin; thisPin <= highestPin; thisPi
  7. Hello, How would I enable the other heater transistors on the Ultimaker shield ? Would I just Edit the Pins.h file to make sure that the right pins are defined ? #define HEATER_BED_PIN 3 #define HEATER_1_PIN 4 (I know these pins are different then default) #if MOTHERBOARD == 7 #define KNOWN_BOARD /***************************************************************** * Ultimaker pin assignment ******************************************************************/ #ifndef __AVR_ATmega1280__ #ifndef __AVR_ATmega2560__ #error Oops! Make sure you have 'Arduino Mega' selected from the '
  8. Is there anything special that needs to be done to enable the Heater2 and hot bed transistors ? I have tried use these but the lights never come on. Thanks
  9. With more testing, I validated that #define HEATER_BED_PIN 4 was set in the Marlin pin define code. I jumpped a +5v line for the Arduino to Pin3 of the transistor, and the Transistors light came one. This leads me to believe that the Arduino pin 4 is dead. I'm currently in the process of switching the bed to run from heater 2
  10. HOT_BED Transisotor Here are the voltage reading from the transistor to GND. 0v +19v 0v Pin1 Pin2 Pin3 Seems like the transistor is not on....
  11. Yes, It soldered directly to the power input of the 1st power supply. This is a link to the picture of how its wired up. https://plus.google.com/photos/10429557 ... 3516558898 The Terminal block is the 2nd power supply. The black color side is GND and the blue (un colored) side is +19v The White and Black wire are what is run to the headed board. The Grey wire, is where the 2nd Power supply GND is connected to the 1 st Power supply's GND. I made the heated board at home, its has not extra components on it. meaning its just a long copper trace. I wonder if I need to add a resistor
  12. Help ! This is my 2nd attempt to get this working. I used a switch before to turn on and off my heated bed. But I needed a 2nd micro controller to monitor to the temp and turn the switch on and off. Right now I currently have it wired according to the 2nd power supply topic on the page http://wiki.ultimaker.com/Heated_Bed#Heating_circuit "Secondary DC supply, e.g. 12V for reprap pcbs: The ground of this supply should be connected to the ground of the Ultimaker supply. Than one power connection of the PCB goes to the +12V of the secondary supply, while the other goes to the pin2 of th
  13. I ended up ordering the 5/8" Peek Rod from mcmaster, with a M6 tap and the appropriate drill bit. I like the idea to die the bowden and tap the top of the Peek. I'll have to pick up the appropriate tooling for ACE hardware or home depot. Also I picked up a $120 mini wood lathe from harbor freight. I already had a mini drill press. lets hope for no more hot end issues !!!!
  14. Hi, My Peek threads stripped out and the hot end fell out of the peek during a print. Does anyone know a place where I can get a replacement peek ? Preferably in the United states. Thanks, Brian
  15. I had a thought, because the volume of material being extruded is so critical to quality prints. I was trying to think of a way to calculate the amount of material is being extruded. My thought is to use weight to calculate the volume of extruded material. http://www.tekscan.com/flexible-force-s ... ifications Anyone have input on this idea ?
