Most people do use thermistors. The idea behind thermocouples is that they are less fragile and more accurate, as well as requiring less code to read.

Re: Repsnapper Extruder Heat Issue - 13 years ago
The "Save Settings" option is in the top right corner of the input file tab. Doesn't make much sense, I know. It should save all of your gcode settings though.by NewPerfection - RepSnapper

Makes sense. I though those looked way too high resolution to be FDM produced.by NewPerfection - Reprappers
Re: Request Sample - 13 years ago
Unfortunately the RepRap is a rather low-end printer. While the output is amazing for the price, it is not capable of producing anything quite like you've pictured, at least not without a lot of post-print finishing. Edit: I would look through Thingiverse to see examples of what can be done.by NewPerfection - Reprappers

Re: Help with print quality with ABS - 13 years ago
You need the dimension module of Skeinforge activated to get E codes. Also, the first number of lines in your gcode are specified in the start.gcode file.by NewPerfection - Reprappers

Re: Successful Wooden Repstrap - 13 years ago
Very cool! First thing I would recommend is making a spool for the plastic so it doesn't get tangled up. Something like this: . I made one, simply cutting it out of cardboard with a hobby knife. What software are you using? The RepRap Host, Skeinforge, RepSnapper...?by NewPerfection - Reprappers

Re: Making the case for the RepRap Industrial Revolution. - 13 years ago
I think the biggest reason PLA is popular is that it is printable without a raft or a heated bead :-) That's the reason I use it anyways. Made from natural ingredients is nice too.by NewPerfection - General
Re: Wade extruder hobbed bolt - 13 years ago
Too much and you can flatten the filament, or break the idler bracket. That would take quite a lot of force though.by NewPerfection - General

Re: Prints stop after some unknown number of commands - 13 years ago
send.py is command line, but all you have to do is type send.py and drag the gcode file into the command window and hit enter. This copies the file path of the gcode file. Easy as pie.by NewPerfection - Firmware - mainstream and related support
Re: Prints stop after some unknown number of commands - 13 years ago
I've had the same issue with the host software, where it freezes after some number of layers for no apparent reason. I use send.py to send gcode to my repstrap, and don't have that problem now. send.py never freezes on me. Are you using the RepRap host to slice the model? If you download skeinforge, send.py will be included. It's a simple command line program to send gcode. I still use theby NewPerfection - Firmware - mainstream and related support
Re: Flexible Coupling - 13 years ago
I use vinyl tubing as a connection as mentioned. It fits really tight over the lead screw, but loose on the motor shaft so I use a hose clamp on the tube over the motor shaft. Works great and is extremely cheap.by NewPerfection - Mechanics
Re: Any comments on UltiMachine plastic? - 14 years ago
Their PLA is very high quality. It's as close to perfectly round as can be. I've printed half of a 5 lb roll of natural PLA and and very happy with it. They shipped very fast too. My last communication with them was answered within an hour.by NewPerfection - General
Re: Skeinforge Raftless Issue - 14 years ago
Also, leave the raft module on. It sets temperature among other things. Just set the number of raft layers and interface layers to 0.by NewPerfection - General
Re: Can a single person with no hands-on experience do a reprap? - 14 years ago
You can definitely do it. I had virtually no electronics experience before I make my RepStrap, and very little experience with any other aspect of it. When I started my RepStrap, there were virtually no other RepRaps out there (this was a couple years ago). I built everything myself based on the McWire design, and put together the electronics from a kit. I now have a fully working printer, thby NewPerfection - General

Re: hot end keeps falling out - 14 years ago
Oh I see, you're using a Wade extruder with a MakerBot hot end. Well, you need some sort of support to hold the barrel rather than the PTFE. Put something similar to rhmorrison's photo on. That peek block holds the brass barrel, so the PTFE is not supporting the hot end.by NewPerfection - General
Re: FDM Reprap kit Support - 14 years ago
Sorry, I was thinking he was talking about the laser cut version. I was saying that he wouldn't get support in the Mendel machine variations forum for it, not saying he wouldn't get support on the RepRap forums in generalby NewPerfection - General Mendel Topics
Re: hot end keeps falling out - 14 years ago
Simply put an M6 nut between the metal washer and the PTFE barrier. That way the washer is holding up the heater barrel instead of the PTFE barrier.by NewPerfection - General
Re: Non-permanent Rigging of a Computer PSU for RepRap (with pictures!) - 14 years ago
I simply opened my PSU, wired up a switch between the green wire and ground (spliced in so the green wire still goes to the 20 pin connector), and mounted the switch on the side of my RepStrap. That way I just flip that switch and the PSU turns on and I can just leave the main PSU switch on. Gives me a convenient kill switch without having to reach for the PSU.

Re: stuck again!!! - 14 years ago
You need another Arduino (Sanguino, etc) to run the extruder board. Edit: unless you do some serious hacking of the extruder board firmware. Not sure how you would even go about it.by NewPerfection - Reprappers
Re: Plastic Parts Dimensions? - 14 years ago
I just use for measuring STL's. It's free, though Windows only. It can measure point to point, line to line, circle center to circle center, or any combination of the above. It's quite useful. Edit: can't remember if it can measure angles, but they would be easy to calculate using three point locations.by NewPerfection - Reprappers
