Re: L-Cheapo Laser with Shapeoko 3

I did a quick test yesterday with curves, straight lines, and turning the laser off and on, and it came out great! https://discuss.inventables.com/t/jjs-x-carve-build/19273/41 From a foot or more away, it looks like ink was printed onto the material. I was quite impressed. It's going to be great to ...

A 2.5 W 12V Laser.
Since the power circuit is all built into the module, there is no power control; simply on or off.

Re: Help for create pcb board from my circuit!

Try using SparkFun's Eagle Libraries. They are much easier to use than the built in libraries. You will be able to find 0.1" (2.54 mm) spacing terminal blocks, and many other variations (3.5 / 5 / 5.08 mm are common). https://learn.sparkfun.com/tutorials/how-to-install-and-setup-eagle?_ga=1.16565919...

Re: L-Cheapo Laser with Shapeoko 3

Since you are dealing with DC, a MOSFET will work as well.
For my laser, I simply am using a IRLB8721. I milled a custom PCB for some easy wiring.
For a pre-built option, this will work from Sparkfun: https://www.sparkfun.com/products/12959

Re: Recieved 4 NEMA23 Stepper, 400mm leads

Definitely larger gauge wires will have less of an issue. It's all a matter of size and scale; i.e. Can you actually measure a difference vs theory.
I think it was the "delay" logic that I heard which raised my engineering BS detector.
Great explanation.

Re: Recieved 4 NEMA23 Stepper, 400mm leads

The important thing is that the two Y-axis motors have the same length wires. Cable length is not important for the Carbide Motion board, because the two motors are on separate drivers. It is an issue only with gShield and the Stepoko, because the resistance of the wire matters when you want to spl...

Re: Do background tasks glitch toolpaths?

My concern is stalling, even for a moment, mid-pass and introducing flaws in the workpiece. It would take a serious amount of time (minutes) to cause a problem. Your computer doesn't actually tell the steppers what to do (this is GRBL's job). Your computer only sends the GCode program to GRBL, whic...

Re: Help a noob with coin toss-Shakeopo 3 or X-Carve

Plus, I hadn't thought about the software aspect but do prefer local over cloud based. Regarding the X-Carve: It does not require an internet connection to run Lower price for a similar work area size. Can be purchased in 500mm (~12) or 1000mm (39") sizes (or customized to your liking) However a Sh...

Re: Holes are too small. Fusion 360 Bore

I asked the guys over at the autodesk forum. And they verified that my code was correct. That leaves only my shapeoko.. :| I have to blame my wobbly Z axis I guess, it's about as rigid as a noodle :x Well not quite, but it is a really annoying weak point to an otherwise capable machine. I guess I j...
