potresti mandarmi l'interfacia per il computer quella dove si mette il g code?

per favore..

lmao@Ghetto pen holder :P Nice work man!!

Very nice. One question. I'm assuming you have a third stepper lifting the pen rather than driving a z axis, but do you think it would be possible to use a solenoid in place of that?

[edwardrford]

@ayilm1 Thanks for stopping by! I'm not sure what you mean by lifting the pen ran than driving a z-axis? I'm only using a pen for testing purposes (it's not nearly as noisy as the dremel+ the pen won't cut through my work surface if I mess something up!)

As far as using a solenoid: I'm sure you could do that in place of the acme rod/stepper motor, however that would really limit you to a single depth without having to reset after each pass.

[ayilm1]

@edwardrford Ahh ok I see. I'm currently putting one together to serve as an xy plotter. In your case, the stepper will be the obvious choice for optimum depth control. My design is practically the same but I've replaced the z stepper with a solenoid. Granted as you said, it is fixed distance but it's only for vectors so it shouldn't really matter. My other question was, will I need to modify grbl or does it cater for 2 axis?

[edwardrford]

@ayilm1 As long as you're sending gcode to GRBL, no modifications will be necessary. But is that the case?

I'm not sure how you're going to tell the solenoid to move? Do you have a relay or something setup? Send me an email [edward at shapeoko (the dot goes here then a com)] with more details of your setup and we'll see what we can do.

For anyone that's wondering; I've figured out what that horrible squeaking noise is! The cross piece for the x axis (the part that's hidden under the work area) was actually rubbing on the side pieces. A little sandpaper fixed that. For the next version, i'll be sure to leave a little more space!

very nice!

Yep, a perfect freaking logo!
