I was thinking the same thing but I know if that woul be worthwhile. Thanks.

 

Where do I get plates,

 

Now that I'm finally in the wiring stages of my build, I realized that I have another question...How are the connections that go to the 5V or ground pin on the Arduino to be hooked up? I ask because I have four drivers...are they all to be hooked up the same and run to the pinouts on the board?

 

That's great. I ordered them and they will be arriving today. Thanks @Kyo

Just to clarify...do I need to hook up to both the 5V and the ground? Based on the wiring diagram it looks like it's one or the other.

I've purchased a 52mm 400watt Spindle motor and wonder what I could use to mount it to the C Sphinx

 

Yes My son does have a 3d printer. the stl would mount to the OpenBuilds double wide gantry plate?????

 

I'm in the process of putting mine together. The entire assembly was loose up until now. But something isn't right as one plate hits the ends before the other. It's about a 1.5mm gap. The only possibility would be the c beam not being cut perfectly. It may be just the one I'm using for the gantry. It may be all three. I don't know. Would it be OK if I kept it forced square with the lead screws? As in, secure one side against the plate, then install the other lead screw and rotate it until the other side hits.

 

Can you please provide a link where can I get all the parts for this build. I do not have access to cnc to fan these myself. It is a great build and I am drooling over it

 

Do the new plates that Chris selling accommodate secondary backlash nut which was not fitting due to spacing in original version ?

 

Talking about that: I still don't get the need for a secondary anti backlash nut. Could someone explain the idea behind that?

 

Aaaaaaaah - OK. Now that makes sense. Thanks

 

Would this build be able to cut some lightweight aluminum ? I build scale rc helicopters and time to time need to cut small parts . 1/8" aluminum is common and in some situation, I may need to cut 1/4" as well.

 

@ashish B Simply put yes ;-)

Great. I am loading up shopping cart . Is there a way to fit ball screw instead of acme

 

I used duct tape for mine.

 

Hey Kyo,

The BOM calls for a 40 Tooth timing pulley, but these are no longer in the OB Parts Store. Can you advise?
http://openbuildspartstore.com/3gt-gt2-3m-timing-pulley-40-tooth-high-torque-series/

I am trying to price up what the Sphinx is going to cost to build, but its looking like its coming in quite a lot more than something like C-Beam kit.

Thanks
Chris

 

I found the new BOM the one under Parts List is old and out dated. I think the price its coming to is going to push me towards to C-Beam kit instead sadly.

I assume that at a later date the parts from that can be used to create me the Sphinx of my dreams

 

I guess I will go with as is option and look to upgrade one at a time starting with z axis . I need a machine to machine another machine .

 

If you source your parts from Aliexpress you can spread your dollars farther. I recently made a cbeam plate machine from chinese sourced parts. grand total including motors and electronics was close to $500. The only parts ordered from the openbuilds parts store were the extrusion and the spindle mount. ( hard maple or ipe was not suitable for this)

It definitely took some planning and research, a few things arrived damaged in shipping ( only cosmetic) but aliexpress has a fairly generous consumer protection plan and I was able to get some hefty discounts because the supplier sent me scratch and dent aluminum plates instead of new ones.

My nema 23 wantai motors are fast. I have been running my plate maker cutting hardwoods at 1-200 ipm with a climb cut and a razor sharp carbide upcut spiral. I spent around $140 for the motors, drivers, and controller.

My only caveat was everything was in MM so i had to constantly convert from imperial to know what I was ordering.
