I have downloaded the .DXF file for the thick sheet parts for my Mendel and I am about to send it to a laser cutting company. What material should they be making it out of? It is not specifically stated in the BOM. I was planning on specifying 1/4" plexiglass, would that work?

Hello from Saskatchewan,
I live in Regina and I have collected all of the parts for a Mendel except the set of printed parts. I would like to get started building but I am sure that you are all aware of the challenges in finding these parts.
Is there anyone in Vancouver who would consider helping out a fellow Canuk by printing me a set. I am more than willing to pay any reasonable asking pric

I have been looking around at various prototyping and manufacturing equipment and they all seem to have some things in common. A number of stepper motors are driving a cutter/printer/extruder head of some kind. I wondered why we have to put a motherboard and stepper motor controlers on each machine.
If there was a Mendel in my office, a 3 axis plasma cutter and a 3 axis mill in my garage and

Thanks Spacexula
Yes, it was incredibly naive of me. I had looked at a number of the other forums but I was well into the procurement process before I found this particular one.
Of course, then the alarm bells went off.
Oh well, it wouldn't have stopped me anyways. this thing is just too cool to not build one, no matter what obstacles might stand in the way.
I didn't know about the maps.

I have almost all the required parts for a mendel. Even the electronics are on the way. The only thing that I can't seem to find anywhere are the parts that I expected to be the easiest, the repraped plastic ones.
I see lots of people looking for parts but not very many people able to provide them. I bought the molded vertex parts from James Villeneuve and they look just fine. I am sure that

Thanks triffid_Hunter.
I am not an electronics whiz but I can use a multimeter. I will be able to work it out from your description.

I notice that this is a 3.5v motor rather than a 12v. Dopws that make any difference or could 3.5v motors be hooked up to the reprap's electronics? And if so, what changes would be necessary to do it? I have a batch of 3.5v nema17 motors at the moment but I was not planning on using them for my Mendel since it calls for 12v ones.

I bought 4 used steppers on Ebay. They are described as:
Type 103H5208-0842
Sanyo Denki
2.0 OHM
STEPPER MOTOR, 1.8 deg 200 steps/rev when full-stepping
Description of their wiring was as follows:
RED = A
BLUE= B
YL = A-
ORG = B-
BLK = COMMON
WHT = COMMON
My problem is that the wires are all the same color on the actual motors so it doesn't do me any good. Can anyone describe how to

By now many of us in Canada have already found out that McMaster Carr does not ship north of the border. There was some discussion in the forum earlier that identified a company called SDP/SI as a possible source but no part numbers were given.
I think that I have worked out the necessary part numbers for the two belts based on comparisons with the specs from the McMaster Carr belts. They are:

Is there a single document anywhere that gives the North American substitutions for the reprap mechanical parts? I understand that 5/16" threaded rod can be used for the studding so I assume that the same measurement will work for the barstock but what about the rest of the fasteners? Has anyone put together a full list of the non-metric options or do I just figure it out myself?

Thanks triffid_hunter, I had no idea that I needed a load on the 5v line.
It's the electronics part of this that worries me the most. I will buy the boards from Makerbot but if I have any problems getting them to work I have no idea how to troubleshoot them. I guess I will figure it out as I go!

I am just starting to collect all the bits for a Mendel and I have a question about the power supply. I will probably want to add a heated bed fairly soon after building it. Will a 400w ATX power supply run the machine and still have enough left over to run a 12v heater for the bed?
I haven't even done any planning on the heater so I don't have any estimated power consumption figures. I don
