newbie planning stage

Im planning a build and im just want a few questions im trying to figure out to try reduce costs,
1. In total length what m8 threaded bar ill use and smooth bar so I can order the amount,
2. for the ramps v1.4 is it possible to make it yourself all I need it circuit diagram I can etchit on and make my own as It will reduce cost.

The RAMPS 1.4 source files.

If you are in the US, I would recommend that you skip this (unless you really want to of course) - bare RAMPS 1.4 PCB's are available for $10 and a whole solder-it-up-yourself kit is $45. I tried to source the components myself but shipping costs swamped my savings, so I just ordered a kit.

And what machine are you building? Prusa i2?

Yep im thinking of building prusa i2

6m M8 threaded rod
3m M8 smooth rod

Ty for measurement, I was looking at this wiki and its based on working with pla, what will I need to change to work with abs ty

Well, PLA and ABS require different environments for the best results.

PLA likes to be cooled fairly quickly (with the aid of a fan) after it is extruded. It does not require a heated build platform but having one makes life easier. Also, you may need a fan blowing across the hotend to print PLA - this depends on the hotend though.

ABS like a warmer environment. You can print it in a cool room, but you may run into warping. ABS requires a heated build platform and does not need a fan.

Printing ABS can be a bit much in the beginning, I would stick to PLA at first then once you feel confident move into ABS.

Well got my hundred m8 bolts thanks to work just need 100 washers ill get them tonight lol

For the Ramps you can get a arduino Mega for $38 from mouser.com if you buy the A000067 version.

Also if you are in the US, look at McMaster-Carr for smooth rod. You can get 3 feet of 8mm for $5.60. PN# 88625K67. McMaster-Carr doesn't tell you the shipping cost. But I paid $13 for shipping, I am in Texas.

And finally you can get LM8UU bearings for $1.75 each from Ultimachine.com.

You might know where to get these already, but I thought I would share, because I overpaid for all of them the first time around.
