Greetings, So I sold my Prusa and my new printer uses 1.75mm filament. I would like to trade or sell the rest of the filament that I have, as I have no use for them anymore. I am in woodbury, MN. 5lb of new in the packaging silver Ultimachine PLA 3mm - $70 4lb of used white Ultimachine PLA 3mm - $40 Thank youby BobFA - Minnesota Twin Cities RepRap User Group
Hello everyone, I have for sale my complete prusa 3d printer for $350. I am in Woodbury, MN and I do not have time to work on the printer and I bought the MakerGear M2. I know that two wires need to be resoldered but everything else is good to go. Below is a list of products that are on the printer.

Fixed I bought some 14 gage wire rated for 15 AMPS and everything works... for now. So I believe what happened is that the 22 gage wire had to many Amps running though it that eventually the wires melted together. The good thing is that the heat did not kill my RAMPS.by BobFA - Reprappers
Hmmm.... OK so more tests Test One: I bought a switch, directly connected the - to the heat bed and + to the switch to heat bed AND... nothing? Test Two: Directly connect the power to the heat bed and it started to heat up. At 37Celecous my wire smoked up and melted... I got quite excited and pulled the plug (it's quite stinky) After opening up my window I cut the melted wire off. Photos ofby BobFA - Reprappers
Hello everyone, So I have RAMPS 1.4 , X power Pro 650W computer power supply, and MK1 heat bed. I have printed about 3ish pounds of filament so far and today as I was printing I noticed that the heat bed stopped heating, after some testing I found that if the heat bed is directly connected to power it heats just fine but now if it is connected to my RAMPS board it blows my power supply.

So.... how is the plastic? I ask now because UltiMachine raised there prices and I feel that I should buy while its cheap.by BobFA - Idaho RUG
So have you got the PLA yet? How is it? I am also looking at them as a potential supplier.by BobFA - Idaho RUG
So I have been looking around and changing Marlin but no matter what I do my Reprap does not recognize my mechanical endstops, Sprinter on the other hand works right though. I even went through Misan Marlin file but still no response. Can someone look though my config.h file and see what I'm doing wrong? THANK YOU Also included is my Sprinter config.hby BobFA - General
How do I do that? I sent G28 and it proceted to bash itself into its endstops. How do I change it?by BobFA - General
Prusa->RAMPS 1.3->Arduino 1.0->Marlin 1.0.0 I want to use Marlin->Slic3r->Pronterface but I am currently trying to figure out the endstops. I have my X Y and Z runing the right way now but that is the extent of what reseached. I have mecanical end stops and when I am runing Pronterface the reprap does not reconize the endstops at all.by BobFA - General
I am using SFACT, Pronterface, and Sprinter FW. I have already built a Prusa Reprap and I have been messing around in SFACT and as you know it is set up for a 0.5 mm nozzle and I have a Makergear 0.35 mm nozzle and when I change the settings to 0.35 prints seem to be messed up (works better set up as .5). I was wondering if I could ask for some start up numbers for my 0.35 nozzle for SFACT. THANKby BobFA - Reprappers
"The bottom pair of connectors marked 5A power the stepper drivers and Extruder heater/fan. The pair of connectors above marked 11A power a Heated Bed, or other output." Ok so since I'm only powering the stepper drivers and Extruder for now I only need 12v 5A of power to the bottom of the connector not the top like I have in the picture.by BobFA - Reprappers
Just a final check Could someone tell me if what I'm doing will work? Thank You So set up contains ATX Power Supply (Specs) and I am connecting a coupler to it ( yellow I believe is +12v and black is ground) leaving out red(+5v) and its black (I think) and twisting and soldering on 22 gauge wire (rated at 300v 80 Celsius(176 Fahrenheit)) red to black(ground) and black to yellow(+12v) HERE (I knoby BobFA - Reprappers
So I was just given X-Power Pro 650W PC power supply. 1. Should I have any problems with this? Like over powering my RAMPS or Heat Bed? for example On PCPowerSupply reprap wiki it says that "On the ATX 2 power supplies, there may also be additional sense wires that need to be connected to the corresponding voltage. These are usually thinner wires, and should be connected to a wire of the sameby BobFA - Reprappers
I am sorry if these questions have already been answered but I ether can not find a concussive answer or nothing at all. 1. I have remade RAMPS v1.3 and a MK1 heat bed (http://www.ebay.com/itm/RepRap-MK1-Heatbed-Heated-Bed-Heat-Prusa-Mendel-/130587006465?pt=LH_DefaultDomain_0&hash=item1e67979601) I still need a power supply 1.1 What power supply do I need?

Is it ok to use plexiglass for the print bottom plate? I have not seen anyone with a plexiglass bottom print plate, but I had some available and thought it would look cool. A question I have really is will I be able to epoxy it to my PLA bushings? and will it be to heavy? The plexiglass is .233"/5.94mm thick.

Mendel-parts.com is closed for new orders at the moment so it looks like I will have to order V5 from some where.by BobFA - Reprappers
OK so 4th of July weekend was busy for me but now I edited the next videos. I received my RAMPS and motors this week from UltiMachine and they gave me some red and blue filament for free. I do not know if it is PLA or ABS. Part 2 Part 3 Part 4 I am still looking for a hot end, any suggestions?by BobFA - Reprappers
Hello All, I am an Architect Student and I am building a Prusa. I am documenting this and putting it up on YouTube for my class/department. Of course since this is my first build and new to this my videos will not be professional quality. Any pointers as I build will be MUCH appreciated. Link Intro Part1 One thing I am suck on is the hot end, I would like to buy a V6 hot end but I do not see aby BobFA - Reprappers
