Thanks, Ian and Wade! Wade: I'm glad someone else has experienced this problem and it's not just me. I'm going to follow your lead and forge ahead. Like you said, the performance of the temperature control loop is not critical. Whew... I'm glad to be past this. ~Andy P.S. Good luck with your hesitation bugs.by Andromodon - RepRap Host
Thank you, Ian! Just for confirmation, do I just need to delete the objct file associated with the cpp file I'm editing, or do I need to delete all of the object files?by Andromodon - RepRap Host
As another question, how does one remove a "pin" from the RepRap world map? It looks like someone spammed Minneapolis, MN, USA by putting a pin for a business instead, "Timeout Restaurant & Sports".by Andromodon - General

I tried, but it didn't seem to work. I'm new to this Arduino stuff, so maybe I did something wrong. Here's what I did: I edited the file in the arduino libraries directory (/opt/arduino/arduino-0011/hardware/libraries/ThermoplastExtruder_SNAP_v1/ThermoplastExtruder_SNAP_v1.cpp on my machine) to uncomment those two lines. Then I deleted the corresponding object file (ThermoplastExtruder_SNAP_vby Andromodon - RepRap Host
No problem! I'm glad you got it to work!by Andromodon - RepRap Host
Alright, guys... I think I found the problem, and it's in the Arduino firmware. Looking through the reprap-host source code, I traced the series of steps that would begin when I hit the "Profile" button in the Extruder profiler. Eventually, clicking that button results in the following 5-byte message packet being sent to the Arduino (see below). This is supposed to communicate that the host cby Andromodon - RepRap Host
I caught something in your original post, "When I put the disc into the pc ReprapLiveDVD-0.6.iso comes up in a window under D:\ drive." This means that you burnt the CD image ReprapLiveDVD-0.6.iso onto a CD like any other file. This, unfortunately, won't work, and your computer will not be able to boot from the resulting CD. What you need to do is burn the image to the CD like an image insteadby Andromodon - RepRap Host
I think I found the message processing area of the firmware. I still need help though.by Andromodon - RepRap Host
I am using the "Extruder Heat Profiler" in the reprap-host program. You're right about the behavior of the extruder exerciser, and that works fine for me. I am using reprap firmware V 1.3 (the single Arudino snap file), and reprap-host from 2008-05-23. I am sure i have the right thermistor data in my firmware, because the thermistor test and extruder exerciser both give the correct temperatureby Andromodon - RepRap Host
Ok... I've done some troubleshooting steps to try to narrow down the source of the problem, but I still need some help. I've hooked up an oscilliscope to pin PWM/DIGITAL6 of the single arduino in my setup. This is supposed to output a pulse-width modulated signal that is essentially buffered by the PWM Driver board. Whenever PWM/DIGITAL6 is high, the heater is full on, and whenever it's low,by Andromodon - RepRap Host

I have an oscilliscope that I can use to monitor my nichrome wire heater signal. Does anyone know what the correlation between "power settings" and duty cycle should be? What is the expected duty cycle for a power setting of 15? Also, the output should be 0-12V, right? Thanks for your help!by Andromodon - RepRap Host
Ok.. No one seems to be able to help so far... Maybe it would be easier if I asked more specific questions. What temperature does your extruder plateau at with a power setting of 15? Mine will go all the way up to 200C if I let it. I don't know if this is normal or not. If you (yes you! have a spreadsheet left over of power settings and their corresponding temperatures, please post it.by Andromodon - RepRap Host
The advantage of lots of people using the same open source software for RepRapping is that it's easier for us to share designs with each-other and for objects to evolve as people find ways to improve them. Each CAD software has its own native file format (am I right here?), so in order to share and edit files most efficiently, it would be nice if we all huddled around a single piece of software.by Andromodon - RepRap Host

I am pretty confident that my temperature readings are accurate, as both the thermistor and thermocouple I have record the same temperature. Any thoughts as to the cause/solution of my situation?by Andromodon - RepRap Host
Hello! I am in the "Calibration" stage of building my extruder. I am having problems, though. When put 150 as my max temperature and click on "Profile" in the "Extruder Heat Profiler" window, the following happens: 1.) In my console: "Heater output 0, ambient temp is 30.0C" (that's good) 2.) It starts at Power setting 15, and in a few seconds (10-15 seconds?), the temperature is up to 45.by Andromodon - RepRap Host
Are these two files supposed to be in sync? I'm not sure. I AM pretty sure that '.../reprap-arduino-firmware-1.3/library/ThermoplastExtruder/ThermistorTable.h' and '~/.reprap/reprap.properties' are not supposed to be kept in sync. The values in ThermistorTable.h are supposed to reflect the actual physical thermistor used, while the values in reprap.properties are supposed to be set to certaby Andromodon - RepRap Host

Hello great people! Do any of you know what I should put in my Arduino Firmware's ThermistorTable.h if I'm using the thermocouple on page instead of a thermistor? Also, do we use the same settings in reprap_host's properties for a thermocouple as we are supposed to for a thermistor? Here are the pertinent properties, as I understand them, for a thermistor: Extruder0_Beta(K) 550.0 Extruderby Andromodon - RepRap Host

Wow.. I feel stupid... That was the problem. Now, cool iced water gives 5C (probably wasn't in thermal equilibrium yet) and boiling water gives 96C. Yay. Why aren't we using the Beta and Rz associated with the actual thermistor? Or, if these parameters are meant to be some sort of constants, why are they visible to the end user?

It would really help if someone with a working RepRap that uses a thermistor could post the values of R1 and R2 that are actually on their board, together with their ~/.reprap/reprap.properties file and their .../reprap-arduino-firmware-1.3/library/ThermoplastExtruder/ThermistorTable.h file. Comparing working versions of those files with my own might let me know if it is a configuration problemby Andromodon - RepRap Host
Tobias, Yeah, this is the same story as the z-axis post. I did a count last week and saw that I didn't have enough toothed (like a gear) parts to finish the project. I think having a Y motor coupling will fix the problem and get me going again. ~Andyby Andromodon - Wanted
