Found the glitch, I changed the firmware to a honeywell 100k thermistor, 7 and it seems to be working now. Unfortunately though, the heater doesn't seem to be working. Interestingly enough though, when I hooked up the nozzle to D10, there was only .003v, yet 5.6v on D9. So I tried hooking the nozzle up to D9, and then D9 only had a .003v and 5.6 on D10, like they flipped flopped hahaby Vortex87 - RAMPS Electronics
So from my sainsmart kit, I got 2 replacement polulu stepper drivers in today and was excited to start printing. So like the title says, after I got all the axis's moving successfully, I focused on the extruder. I have a 100k little glass bead thermistor which I changed in config.h. and when I tested the output signal with my multimeter I was reading 4.9v. When I attached the thermistor it didn'tby Vortex87 - RAMPS Electronics
I am absolutely certain I have all the wires hooked up correctly voltage wise. Regular standard 12V off a PC power supply, yellow for positive, black for ground or neg. Well yea, that sounds about right about that particular component, it smoked instantly. So, it just so happened I had a spare Arduino that I was saving for a future project. I swapped it out once I made sure the problem was fixed.by Vortex87 - RAMPS Electronics
I do have a multimeter and my power was an even 12 volts. I don't have a heated bed, which I narrowed down as the cause. The smoke came from the chip nearest the power jack on the mega. I took out the 11A plug and tested it again and things were fine..by Vortex87 - RAMPS Electronics

I woke up this morning pissed off, I had my printer make a part overnight. The machine was stopped, but not where it should have been.. This problem has occurred before too, and I think I've narrowed down some potential explanations.. I have my reprap running off a power strip on my desk. In this same power strip is my laptop, small rope light, and a fan. At one point, I intentionally tried to caby Vortex87 - General

So will this be a Slic3r setting? I didn't see any heat or temperature settings in Slic3r.by Vortex87 - General
So this is a problem I've been having for awhile now.. I've attempted to solve this before (to no avail). Minutes before I begin a print, I manually set the temperature to prime the heated nozzle. I clean off the tip with tweezers, and run approx 15-30 mm of filament before I even hit "print". When I do, IMMEDIATELY the blue target temperature bar jumps to over 195 degrees.

So I currently have sprinter working well on my Prusa. Hearing many rave reviews of the Marlin firmware, I thought an upgrade was in order. Obviously, I went through the config.h folder and selected my correct electronics, (which requires tools-->sanguino to be selected in the arduino environment). When I went to compile the firmware prior to upload, I recieved the error: FORCE_INLINE voidby Vortex87 - Firmware - mainstream and related support
So I have had a working printer for approximately the past 6 months. The construction and leveling was the easy part compared to navigating the firmware and software settings. My first firmware was the fiveD gcode interpreter which I used for a few months before I upgraded to Sprinter. I know many people now use Marlin, but that's a different post. Anyways.. my first (and favorite) software was Pby Vortex87 - General
Wait a minute...stepper motors are torque limiting devices? So are you trying to say that I shouldn't have a massive heart attack if the flags miss the opto sensors? When I was calibrating my Prusa, at first I thought I was a rockstar. The hot end was working, (before I fried my thermistor) and was extruding little string balls. I got the pronterface software and skeined, a whistle. I then hit thby Vortex87 - General
In the system that I observed, the ends of the wire were secured with a spring-tensioner type system. This method keeps the wire constantly taught, and any slack will be worked out. The double pulley system would improve accuracy by removing any backlash present in the machine. The wire drum could be easily printed and could lend itself to another possibility. Another idea I had came out of theby Vortex87 - General
So this is a concept I've been going over in my head for quite a while now. I figure I'd post this to see if someone else had already tried this approach. This idea came to me while working my previous job at a machine shop. One device that we produced seriously caught my attention, it was a test tube pick and place device. Now I will confess I was slightly turned on at the sight of hundreds ofby Vortex87 - General
I finally successfully uploaded working firmware (5D) and calibrated the movements. The opto's seem to be doing their job, but I'm disappointed as to how easily they can get bent. I think for my next printer I'm definitely going with limit switches, but anyways... I'm currently using an ATX PC power supply and use it as my (on/off) switch of sorts. As soon as I plug it in, I hear the steppers beby Vortex87 - General
So, late last night I was pouring over all the information I could how to set up my gen 6 board. I found a great youtube tutorial that explained how to change the configuration.h, compile and run in the Arduino interface. I followed the instructions to the t, compiled the .pde file, then hit the magic upload button. My first reaction was shock and excitement as my little board sprung to life andby Vortex87 - Firmware - mainstream and related support
Today was a great victory in my reprap quest. I spent 3-4 hours carefully, reading, re-reading, and then reading the instructions some more. I got all the opto's wired and heat shrinked, the only thing I have left to do is wire up the heated nozzle to my gen6 board. So my first objective is this, I purchased extra stepper motors which I currently have wired to my machine to test and calibrate.by Vortex87 - Reprappers
So is it just me, or has anyone else found themselves dreaming of printing their own powered suit of armor? Pie in the sky fantasy? absolutely, but we all have big dreamsby Vortex87 - General
Like most average people I used to watch a lot of news, almost everything completely sad and depressing. After getting involved with the RepRap project I find myself having something to look forward to, everyday, all day. I work a regular job, there are a lot of boring moments, which my thoughts begin to drift to improvements to my machine, or the great inventions to create with it. It is so sadby Vortex87 - General
So I had made reference to this idea in previous posts but I felt it deserved its own topic. Up until a few weeks ago I worked in a machine shop that made medical tools. One part we made gave me great inspiration for a great reprap design. We all know belts can be expensive and more difficult to get, and there are many issues with getting a tight tolerance. The machine we made was a "pick and plaby Vortex87 - Let's design something! (I've got an idea ...)
So, after months of slowly ordering the parts and doing work in my free time, my machine is almost ready. At first I was going to use RAMPS but I liked the Gen 6 simplicity with everything on one board. I will use my arduino mega for the other projects I create with my Prusa. Anyways, I have two computer power supplies (I got them used for a great price) I am just very worried about making sure tby Vortex87 - General
Hey everyone, so I'm a newbie to this forum but I'm in the final stages of my first Prusa Build. As I quickly found out with this project, sometimes there are a great many periods of hitting stopping points haha. I'd save up to buy the motors, then it would be another few weeks before I could find time, money, and parts to make more progress. So yea, I went with the Prusa Mendel, it seemed like aby Vortex87 - Reprappers
I've been in love with RepRap ever since I saw it, it is an awesome machine with an awesome bunch of people working on it. So I'm finally going to pull the trigger and get myself a Prusa Mendel. Out of all the different options, ultimaker, makerbot, etc. RepRap seems to be the most cost effective. I was thinking about going with the arduino mega for the microcontroller.
