Arcs in two methods:

IJ method

G0_ X Y Z I J K

x=end location
y= end location
z= end location
I= Distance start to center x axis

So this M0 code usually stops the machine at this like of code, and it waits. Perfect

Thanks,

I am planning on making a tool changer for my cnc milling machine. Since I am using a dremel tool for the spindle, it does not have the required capabilities for a 100% automatic tool change.

I...

WHAAAAAAT??!!! Sketchup is awesome!!!

It was perfect for me to start drawing up parts for cnc-ing.

Hello again. Haven't been on for a while as i've been busy with school.

Here is the mount i designed for the 4th axis addon:

Here's a design of the 4th-Axis that i made a couple months ago.

I've used multiple Thrust bearings, Regular Roller skate type bearings, and Love-Joy couplers to make a system that will keep...

Simple double sided tape, it's actually very strong, you have to pry the wood apart with your hands to get it off.

Cool! A machine that builds it's own table surface mount. Ingenious!

I need to purchase a good shop power bar so that i dont have to stretch 4 extension cords around the side of the house.

Here are some better photos. i realized i didnt have any real life pictures of it posted :o

Finally finished the machine. I'm using a HobbyCNC Pro driver board, 35v 10A powersupply, 3 Amp Nema 23 steppers. A Dremel 4000 as the spindle, and i have 2 1/8" carbide endmills (one flat end, and...

Gorgeous build. Aluminum machines look so awesome. You sure have an impressive looking and capable machine. The quality put into this build is by far one of the best on this site. Great job, and have...

HobbyCNCPro 4Axis is by far the best in my opinion.

Pros:

- Max 3Amp motors, Voltage between 24v and 42v (most people get 36v power supplies).

- Has chip protection (if motors get...

hmm, i'd have to disagree on that, but also agree. The Dremel 4000 is a very good dremel for mount ability. I use it more my super tiny desktop 3d mini mill with 6" travels.

I agree that you...

Well, in the video, he recommended the one from Buildyourcnc.com: Stepper Driver and Electronics for CNC Routers

It's $60 for the 36 volt one. $43 for the 24v

if you have 4 wire motors, then get the Mechatronics board since it's pre-made and it can use both 6wire and 4 wire. but since i had 6 wire, i still chose the hobbycnc since it had better...

you only need one. the board has onboard voltage regulation, so the one power supply gives 5 volts to the logic part, and the 24v-42v goes to the motors.

The thing with break out boards, is you...

I got 22awg 6channel wire for my cnc.

The spindle i use is a Dremel 4000. I dont think i need to worry about that much of an emergency. I just need the power to the board to stop, and the computer to be signaled. I can easily yank the...

okay, that's what i have; a switch that does everything.....

The switch i have is basically two switches in one. you press the button, and one circuit opens(no power go through), and one closes...

how should i do it so that i dont have to hit two buttons?

I use these kind: CB Radio/ Ham Radio Microphone plugs, you can get them in a variety of pin numbers: 2,3,4,5,6,8. I personally have the 6 pin plugs since i have unipolar motors.

Is that power switch on the DC side? i've been warned of voltage spikes when the switch closes, but i guess you can solve that with a fuze on the driver's side of the switch to protect.

Also, i read in a post from 2009 that you dont want to have a switch on the DC side of the power supply due to possibility of voltage spikes when the switch closes, is that true? is it something to...
