My Shapeoko build starts

[lioramsalem]

Hi all
Started my journey with Shapeoko 2.

I still have a lot of open thoughts but I've started with ordering the ACME upgrade and Z axis mount upgrade (even if I'm still not sure I'll go Nema 23 path ordering it later will make me pay international shipping again...) from Shapeoko store before they go out of stock again.

Open things:
1. Nema 17 or Nema 23?
2. which spindle should I get? (another thread open on this one)
500w brushed spindle? (~100$) vs 400W brushless spindle? (~230$)
3. TinyG or gShield? I like the extra motor driver on the TinyG but a little afraid of the first time configurations for Noob as I am.

I still have few weeks before I'll place my order, my last exam in the University is on July 3rd if the Shapeoko will arrive before there's a big chance I won't make it to the exam

Cya,
Lior

1 - NEMA 23 motors are for people who are in a hurry, or making money.

2 - either of those spindles should be fine --- what there is data-wise is on the wiki: http://www.shapeoko.com/wiki/index.php/Spindle_Options and http://www.shapeoko.com/wiki/index.php/Materials --- I was cutting Ipê w/ a 400 Watt Harbor Freight 1/4" Trim Router the past weekend

3. The extra stepper is nice, but there've been a couple of people who've found configuring a TinyG overwhelming (says the guy who's still puzzling out his Smoothieboard).

Thanks Will!

OK, I've decided going NEMA 17 for now.

I'll go with the brushless motor as it seems it has much more torque...

3. The extra stepper is nice, but there've been a couple of people who've found configuring a TinyG overwhelming (says the guy who's still puzzling out his Smoothieboard).

I thought so, decided to take the safe route and start with a gshield with NEMA 17 for a well documented setup.

Hi all,
Placed an order for the 400W brushless spindle.
The cheapest one I've found was:

I hope it'll be OK with woods milling

Also, I saw that the gshield finally got back to stock at inventables, hope it'll last another week...

Hi,
I think it's a good time to share my build status
Got machine #5840.
ShapeOko kit built with NEMA 17 and gshield.
Limit switches are in place, ACME Z upgrade done.
I'm using 400W brushless spindle and controlling the speed using GRBL v0.9,
I like it a lot, no need to touch anything, all control is from the computer and the spindle goes off when done Also, it's much easier to get familiar with the needed spindle speed and set it up each time.

Had some issue with limit switches at first but sorted it all out. (capacitors, cable shielding grounding, stronger pull-ups)
I didn't want vacuum cleaner attached to the milling head cause it's too loud, so I've built a full enclosure to have better dust control and reduce noise.
Installed a temperature and fan controller to have better control on the gshield, spindle, spindle controller and AC-DC power supplies status.

And some pictures of course,

Electronics pictures.
I know wiring is a little mess, but now it's time to focus on creation, I'll get to it at some point.

And finally, my first serious run of the machine.
Came out super smooth and accurate, now I just need thinner bits for more detailing

Congrats for achieving this.

How long did the run take ?
What are the dimension of the carbonite ?

Thanks!

The end piece size is 125 x 55 mm

I've done it in two stages:
Roughing phase: 4.5mm flat end mill at 750 mm feedrate. 2mm depth per pass, 4 mm stepover - took around 15 minutes.

Finishing phase: 3.125 mm ball end mill at 1500 mm feedrate. 0.2mm stepover - took around 1 hour.
