CNC Stepper Motor Demonstration

Jeff Beck - Angel Footsteps over the guitar machining, then Joe Satriani - Time Machine for the last half.

Great Video. Who is the artist and what is the name of the song in the background, near the end of the video? Jeff Beck?

Nice piece of kit. Well powerful and fast.

the must, excellent!!!, the perfection.I have buy today my cnc router. I make a guitar like this, where you have find the gcode of this job( 3d shapes!)?, please your help is appreciated.
Good job

excellent!

Homeshopcnc service was great, posted from California on a thursday arrived in UK following Monday. Would have cost much more to buy equivalent motors in the UK.

Nevermind, I just watched this at home (with sound)... 12.5A, makes sense with (6/1.41)*3. Best Regards... :-)

Haydn, What power supply are you using? Each of those motors is 6A per phase... I'm getting ready to buy a set with G203V's. Are you running them at a lower Amp setting? If so, please share, your machine looks like it really cooks. Nice job. How was the service at homeshopcnc?

Many thanks...

Sorry no plans available but may put something together in the future. Its 50"x36"

These rails should not really be used on their sides. They don't flex but bearings wear prematurely due to uneven load distribution. This was temporary, I am currently changing them for Hiwin profile rails and carriages as originally intended but budget restrictions made it difficult when I first built the machine. Any local engineer should be able to do machining for you.

Hi Haydn, absolutely gorgeous machine! I've just started on a very similar build. If you don't mind me asking, ould you recommend someone to do the machining on brackets etc?

One thing though: I've never seen fully supported rails used on their side before (on your y-axis), don't you have problems with them flexing? That steel gantry must be rigid as can be! I'm stuck with rexroth profiles..... Thanks for posting!

Hi! I like to have one like this. Where did you get the plan? Or can you give me links. Whant is the size of the table? Is that 4'x 8'? Thank you.

Job zero is the top of the body. At tool change I touch on this surface and re zero the Z axis. Thanks for the comments!

Great! Just a question: how do you reset the tools height every time you change them?

wow thats sweet :P i got to make me one of those! :)
