Markings reveal its version 2.2 of the board. What is the stepping set at on this particular version ?

Yeah, you have a newer version of the board that doesn't need them set. Guess they're now functionally built-in with the correct values.

Following on about the thumb screw caps, as it is, I had a hard time finding them, or rather, finding them cheap or with cheap shipping.

29$ for a pack of 50, and 29$ worth of shipping (without even thinking about custom and duty), it was enough for me to actually designed one and 3D print them. After all, I have got to use more the 3D printer I built for myself :lol:

You can see the difference between the thumb screw cap provided with the clamp kit, and my version.

The model included has an opening of 10.1mm for the screw head. And depending on the precision of your 3D printer, this opening could turn out to be too small. For me, it was a press fit, hand pressed, but after fitting 16 screws one after the other, my hands hurt for an hour or so. So, YMMV.

What size SHCS do these fit?

And the first "hard" result. After 2 of 3 air prints, I realized my Y and Z axis were reversed.

After figuring out how to change those values, now the jog pad in the Carbide 3D software moves the head in the direction of the buttons (seeing the buttons as arrows).

Now my journey really begins. I have to tidy up the cabling with sleeving and eventually a cable drag chain, but first, I have to look into the finer alignment as it seems my X axis is lower on the left.

At about 1 hour into this project per week, I can't wait till X-mas to be able to spend a whole day with my newest sweetie :P

The screw provided by Carbide were of course M6 to fit the screw in the metal bed, but now that I have the caps on them, I cannot read the exact stamped model on the head. Sorry. :cry:

With the caps on so tight, there are not removable.

Those thumb screws are really cool. :)

I'm looking at getting a small mini-lathe, to create my own screws, hand dials, and similar. (really just to broaden my knowledge of making things too). :)

Right in my line of thinking!!

That is how I got into 3D printing in the first place. It was mainly for the journey, the learning and to put it simply, the fun of it.

Now, my journey begins with CNC, as a need to improve my 3D printing. On my self designed 3D printer, I had a company, DixieBillet, mill parts for me. Those parts were obviously 3D printed first, then for ultimate precision, I sent them to be milled out of alu.

So, I guess, CNC is the next step in "my" evolution. I guess you are further down the road from me, cause I think a lathe would be sweet to add to my arsenal too :P

This week-end I had more time to play with my Shapeoko, I mean, continue the build. I know, I have drawn the Shapeoko "Hello World!", but that doesn't mean the build is over. Far from it.

Last Friday I noticed an "official" limit switch kit on Carbide's store. While I find it simple and effective, I was wondering about the clearance between the M5 spacer and the wheel on the Y axis. Using a thin and long M5 spacer, one I got at Openbuilds, I affixed the spacer on the Y axis and I found the space between the wheel and the spacer itself to be quite small. While there is space and the kit will work without problems, I'd love a little more spacing. I'd move the holes on the Y axis plate a good 5mm higher to ensure clearance, and to make sure if the machine rams the limit switch, no damage to the wheels would occur. But that is just me, the kit is fine.

Carbide's kit is obviously for homing, but I know limit switches can be plugged in parallel and serial, as demonstrated in an easy to understand pictorial here:

http://www.hobbycncaustralia.com/Instru ... Switch.htm

Then I thought why not trying to use 2 limit switches per axis. This is what I came up with:

And the business end:

As you can obviously see, I tried to kill 2 birds with one stone here. A dust cover and the X end, and a limit switch holder.

Now, I will have to wire the end switches (parallel vs serial) and see if indeed 2 switches can be used per axis. All I have are Dupont connectors, the same you would use on a PC motherboard headers. The seem to fit the grbl board, but man, there are a tight fit.

I used regular 3D printer limit switches and added a PG-7 cable gland to have a nice and cheap cable stress relief. The 3D printer limit switches might not last long in the dust, but I paid 8$ for 30 of them so, there are cheap enough to replace.

If I succeed with my wiring tests, I'd print a second cover (while fipping it in the design), then use XTC-3D to add a nice finish to the boxes and paint them black.

Anyone tried to wire 2 limit switches on Carbide's grbl board yet ?

Any help would be appreciated.

Its been a slow December but I managed to complete the limit switch mounts, for both minimum and maximum limit detection (except for Z of course).

My previous post shows the Y Axis mount, here are the X and Z axis mounts.

(Sorry, the STLs are too big to be posted in the forum)

I am still not done wiring the limit switches, but that will come soon enough :oops:
