Build Thread- A4 build log

[saundby]

zhanx, great thread!

I'll be using EMC2 with my A4 as well. We'll have to share tips and techniques. I'm looking forward to getting some fine detail out of it like John (microcarve) has with his lithophanes. Not on day 1, perhaps...

Ok time for the setup phase for the EMC2 for the A4

A photo walkthrough :

Your basic starter screen:



Right now we are gonna use a new setup like this, aka no changes off default:



I only changed the name of this setup so i can remember it if i get another machine later:



Now when i wired my machine I oops and swapped the X/Y axis so a quick fix here and my machine is right again:



Quick three in a row:







Ok my setup: first all my steppers are 1.8 degree, 200 steps per revolution.
I do't have a pulley system so it stays one to one. Next is the leadscrew pitch which microcarve said is a 12 (thanks for that by the way). I played with the speed and google a bit before settling on it at .2 as its smooth and doesn't skip. And of course table travel is based off microcarve's specs.

And finishing up the setup:






Which now gives you three icons on your desktop:



Double Clicking the launch icon starts EMC2 with your setup.

Questions go!

(more to come)

installed my tool head mount from k2

Very nice!

I'll be using a Gecko 540 driver, so once I post my setup we'll have the start of an EMC configuration database for the A4.

Looking forward to pics of your first cuts with the A4!

The only changes I see happening are maybe the pins. The speeds are limited by the machine I would think.

got side tracked for the last 24 hours, My first project with the CNC machine:








Just a home brewed 3d laser scanner, nothing big.

PLANS OR IT DIDNT HAPPEN!!!!!

Can you program in c++? I will be releasing everything as opensource for this project and dont you see the drawings in the posted above

[zhanx]

on a real note:
It’s the first real thing coming out of my A4. The hard part of the math for the scanning is "solved" till I get it up and running. Then I will start a new thread on it, the table is 8" diameter and is being designed to do 10" diameter x 12" cylinder of mass with a DPI of 2400+. Duel Cameras with different colored low powered lasers for trig in parallel image comparison. I got about 2000 lines of code done for it should coming in around 6000-10000+- with full interface face options, and free.

Im learning C++ now, Probably a little heavy for my first few projects . Super interested though.
