Is there anyone in Quebec with a Reparap ?

Re: Mendrel Kickstarter - 14 years ago

The main problem I see with fabroot is that it is not promoting the reprap replication. I don`t want a machine for free I want to kickstart the replication of reprap machines. Like I said to host a kickstart project you need to have a US adresse an US bank account and I live in Canada so I am no eligible. Mabey if I could get MakerBot industries involved in this project as a trusted 3rd party I

Re: Mendrel Kickstarter - 14 years ago

Extra funding could be used to buy more cupcake cnc and build faster and the extra cupcake cnc could be given to the highest pledger level.

Re: Mendrel Kickstarter - 14 years ago

I want to build a Reprap Mendrel and finding printed parts is almost impossible. I think it is because if you build a Repstrap or buy a Cupcake CNC you dont feel obligated to give back to the community because you did it with your money or skills. My idea was to get pledges to buy a Cupcake CNC and material and then give back printed parts kit to the pledgers. The more you give the faster you get

Mendrel Kickstarter - 14 years ago

After seeing the success of the makerbeam on www.kickstarter.com it gave me a idea. Someone could start a Mendrel with kickstart and send parts kit to the big pledgers. I would do it, but since you need to be in the US to start a kickstarter project and I live in Canada, I can not do it Any volunteers ?

Mendel printed part weight ? - 14 years ago

How much ABS plastic is needed to build a Reprap Mendel ? How much would a fill set of plastic part weight ? I am trying to figure out the cost of printing and shipping the new Mendel parts.

Extruder Firmware pin assignment - 14 years ago

I am trying to understand how the pin assignment work for the Extruder Controller v2.2. I want to understand how pin assignment work. In configuration.h.dist #define RX_ENABLE_PIN 4 #define TX_ENABLE_PIN 16 On the chip the pins are 30 for RX and 31 for tx. for the temperature sensor: #define TEMP_PIN 3 It is pin 26 (ADC3) on the chip. #define POT 0 The pot is on pin 23 (ADC0) on the chip.

RepRap family tree - 14 years ago

I know there is allot of RepStrap out there but how many real RepRap made from part printed from a other RepRap or a RepStrap ? I think it could be fun to make a family tree of all the RepRap. If you have a RepRap please post and tell us: Were did you get the printed part from? Did you print parts for a other RepRap?

Re: Using thermocouples instead of thermistors - 14 years ago

Are you using the thermistor input pin on the Arduino board ? Were do you define witch analogue input the thermocouple is connected to ? Luc

Re: Using thermocouples instead of thermistors - 14 years ago

I was under the impression that the Thermocouple Sensor v1.0 had to be connected to an other IO ant that we needed to modify the program in the Extruder Controller v2.2. What hardware are you using wade ? How is you thermocouple connected ?

Re: Is this too evil? - 14 years ago

I would do the opposite. Make a Reprap family tree page were you would see the parent machine with all it childes and grand-childes etc...

Re: RepRap for carving? - 14 years ago

Maybe we could use a Dremel to drill holes and smooth the object after printing.

Re: Thermocouple Sensor v1.0 and Extruder Controller v2.2 - 14 years ago

Before removing parts on my PCB I want to try using the A6 or A7 inputs. If I look at the pin assignment there is: ENCODER_B_PIN 3 witch is D3 (pin 1 PD3 in the schematic) THERMISTOR_PIN 3 witch is A3 (pin 26 PC3 (ADC3) in the schematic) following this logic I will try //#define THERMISTOR_PIN 3 #define THERMOCOUPLE_PIN 6 and see if I get A6 (pin 19 ADC6 in the schematic)

Short thermal transitions extruder - 14 years ago

Inspired by Nophead and Frank Davies I am starting to work on a short thermal transmission extruder. But instated of using a transistor or resistance in a TO-220 package I want to use nicrome wire. My plan is to use have nichrome wire and fire cement sandwiched between a 316 stainless steel washer (MCMaster-Carr 90965A170) on top and a copper washer (MCMaster-Carr 98044A224) on th bothom touching

Thermocouple Sensor v1.0 and Extruder Controller v2.2 - 14 years ago

I just received my Thermocouple Sensor v1.0, Extruder Controller v2.2 and RepRap Motherboard v1.2 from MakerBot. I am looking at the documentation and I cant find were I should connect the Thermocouple Sensor v1.0 to the Extruder Controller v2.2. I suspect I should be using the A6 or A7 header.

Re: Mendel target date - 14 years ago

If you want to build a Reprap you should build the current model. When the next one will be available you can then upgrade by printing the next design.

Re: Plastic recycler - 14 years ago

My meat grinder idea is not for grinding bottles it is for extruding the pellets or grinded plastic. The old meet grinder I have don't have sharp edges, it is basically a meat extruder. For cleaning I was thinking of extruding something to flush the plastic when I am done like water soluble pva then cleaning with water.

Re: Is any one making the parts - 14 years ago

I don't think there is allot of real reprap out there. For what i could read there is more RepStrap than real Reprap. Reprap parts are hard to find. In the developers forum there is a tread about "How do we both encourage RepRap mutations and stay focussed?" If you want the Reprap to mutate you should help it replicate first. I am willing to build a Reprap but I cant find any source for the par

Re: Plastic recycler - 14 years ago

After reading some post and wiki about plastic extrusion I wans wandering if any one tried using a old cast iron meat grinder as a base for a plastic recycler ? I try to get a second one (my wife will never let me modify our meat grinder) and try this to make my own 3mm filaments. I was thinking of preheating the plastic in the grinder and making a 3mm heated nozzle to extrude the filament.
