I am on my way to build a 3 axis CNC milling machine. Now I have got most of the necessary electronic components, such as stepper motors, gecko drives, and power supply.

I am wondering what kind...

I agree, they reply ur emails all the time and the response time is very quick. But sometimes they do not read your email carefully enough, so they miss out some of the questions I ask.

thx hixfixit

ur idea is brilliant

I am on a project of building a 3-axis CNC milling machine. I have purchased the breakout board from CNC 4 PC, stepper motors and gecko drives G203V. I am using MACH 3 as the software, so I'm using...

Dear all CNCzone members~
Hello!

Well, I've been reading on the threads of limit switches, because I need to set up the limit switches and home switches for my little CNC milling machine.

A...

Thank heaps BobT!!!

thx guys, it definitely helps

I am not new to power but I am totally new to heat dissipation and ventilation.

I recently purchased KL- 7212($149/pcs) with 860W, 72VDC/12A.

I am planning to put it into a steel utility case...

Thank you very much, Bubba. I finally got it now. ~

Thanks for your data sheet and pictures

Thx Bubba for your explanation. But it is still a bit confusing to me, I still dont get it why only 1 limit switch is needed for each axix. I will search a bit more on the internet

[QUOTE=Bubba;344867]mealman,
OK, how many switches do you need, is a good question. On my mill drill,I use 1 switch for the X and Y axis respectively (2 switches) and on the Z, I use two switches....

I think I can answer myself now.
It's not really necessary to make the breakout board by ourselves, because we can get them for $25 dollars only from cnc4pc.

CNC4pc offers great breakout board.

Hello everyone, I am completely new to CNC electronics.

My recent project requires me to build the electrical part of a 3 axix cnc milling machine.

I have purchased the stepper motors, breakout...

Hi guys, I'm Kevin and I'm new to CNCzone.

Recently, I purchased three stepper motors from Keling Inc, 3 G203V stepper motor drives and power supply. When I wanted to do the integration between...
