Ok sorry for the edit of my post, But I am interested in this setup. I have a sphinx half built and I would like the switch gears and follow your idea on the rails, So I have a couple of question. I would be interested in buying a set of your gantry plates would they be available from Mr laidlaw or a dxf file? And you used the standard end plates for the sphinx on the axis with 2 motors? And how is the setup with lead screw and the Anti backlash block? Was there a spacer? Thanks!

 

I am also super interested in this build! I would also like the dxf of the plates if you are willing. I am trying to figure out how/if I can fit ball screw into C beam or atleast T12 leadscrew. I have T8 on a workbee now and they seem flimsy.

 

My good, this machine is so sexy, i I had to do it again I would do mine like this.
Do you think it could handle a 1.5kw spindle and mill Aluminium?

 

Awesome! I was hoping that was the case. I'll keep a eye on his Ebay store. Thanks for sharing your build!

 

Also, they are 10% off (the fee Ebay charges me) if you buy directly from me... [email protected]

 

Chris does great work and a really friendly guy.

Did you just screw the rails to the to the c beams? When I looked at doing something similar I seem to recall that base of the rails wasn’t much larger then the the gap of the c beam. (At the top of the chamfer if this makes sense)

I also like the reversed z axis.

 

Cool. My concern is that the top opening of the c beam is about 9mm and this only leaves about 1.5mm on each side for the rail to have contact with the c beam. Perhaps this is plenty enough for it to be strong, I’m not a mechanical engineer.

I was considering milling plates to mount the rails to but it’s a lot of plates to mill and a lot of holes to tap.

Hi
I am also looking at this build but would like to extend it to 1000mm x 1000mm with the linear rail kit and the 1.5kw spindle,just wondering if the 8mm lead screws will take it?

 

does any one have the parts list so i can work out the extrusion
thanks dave

 

this is an awesome build!

I accidentally tripped and fell in a rabbit hole when looking to upgrade my c-beam machine x-axis. I am now planning on building a sphinx style machine and really like this linear rail setup. I am new to linear rails in general and am a bit overwhelmed by all the brands, sources, china knock-offs, etc.

can anyone suggest an affordable/reputable source for these mgn12 rails and bearing blocks? seems like options range from $400 to $1000+ depending on brand alone. what brand do people use or suggest for hobby-esque cnc builds?

also, do the bearing blocks seal well enough to keep dust out? I plan on cutting mainly wood with this cnc router. my current c-beam machine is a dust generator and when attempting to rig up a dust shoe I quickly learned the x-axis was flimsy, hence the trip down the rabbit hole...

 

Nice work !!!, im really interested in make the same build, i just looking arround and i like too much, ¿dou you have the full part list?, ¿did you try to cut aluminium yet?

 

Hi Chris,

two questions.
Which is the size of the real working area ? X / Y / Z -> 450x450mmx150mm ?
Can you provide to me the stocklist for this machine ?

I'm also interested in this build. Is there any drawing of this build that is for sale?
I have aluminium profiles from an industrial machine that I was going to use but it's not the same as you have.

 

How large of diameter screws do you think you could fit? I want to make something 1500x1500 so I think I should use larger ball screws.

 

Where can I find the CADD files for this build?

 

Are four linear rails really necessary for the Y axis? I believe a lot of money can be saved for the same performance by going with a single linear rail with dual carriage on each of the Y axis.

 

Well more rigidity and symmetrical load on 2 rails and 4 blocks might give the impression each rail is more efficient at 50% of the load compared to one rail holding 100% of the load. Kind of like having 2 pair of the same work boots alternate every other day the 2 last longer then the one pair. Hey if you happen to try it let us know I would be interested to your solution how you mounted them. And see performance on one rail per side. Would mount it on top or on side? Personally I have a bad habit of doubling everything anyways.

 

Maybe someone can help me. I bought the kit from Chris and got my rails in but I'm confused by the several thick blocks that came with the plates. What do I do with them?

 

@Giarc - Wow! Did you get them all? I was wondering how hard it is to place the ball bearings back in. I have order my self for the Z and Y axis linear rails. Have a plan to convert to linear rails too. Except I am going to draw up and cut my own plates. Sphinx style and hoping my little 500w spindle last thru all these plates.

@Matthiu - I am thinking those are the blocks the will bolt to the plate as a stand off for the lead screw Anti Blacklash nut block. Block with 2 5mm holes and a slot in middle.
