Nope. It's almost the same. The gantry does lean back a little bit more so the orientation of the work area has shifted towards the back of the machine.

 

Thanks buddy!

 

Worked on the drag chains this weekend. The enclosure is probably next on the list. I'm just waiting on one more material. I say "probably" because it seems like I'll set plans to work on something specific but can easily get side tracked for hours.

 

I still need to settle on some sort of protection for the linear rails & carriages. I'm also waiting for the g1/4" bsp tap to mill a 2 position manifold for the dual coolant nozzles.

 

Really want to go the DIY route. I'm trying to think of a way to seal pieces of rubber together. I know you can cut and fold some materials to make bellows but I think that requires a stiffer material than rubber.

 

Hey thank you! Yeah they are THK 20mm & 15mm rails. My first machine was an Open Builds Sphinx. That machine introduced me to the world of CNC routers and really got the ball rolling for this machine.

 

Thanks! It sounds like you're working on an awesome build. You should definitely start a build log. I considered a fixed gantry machine for the same reason (rigidity) but moving gantry style machines are just so cool. I'm excited to see what this Granite machine is capable of.

 

Working on a more compact, dual nozzle solution. Each nozzle will have it's own flow valve and only one will have coolant for now.


These Misumi extrusions are way thicker than I thought. Very heavy duty. Almost 1/4" thick! Awesome. Thanks to CNCMD for putting me on to these.

 

I added o-ring grooves to make sure nothing leaks.

 

Those pneumatic fittings will be replaced with 90 degree fittings and a hose will coonect each noozle to the valves behind the Z axis.

 

Haha thanks buddy!

 

I am using a small oiless air compressor from California Air tools. It's not crazy powerfull but it is quiet.

 

I've seen them used also. I like that they are designed with long duty cycles in mind. My small compressor is quiet but it is constantly running due to it's size.

 

Something fishy is going on. I removed the bottom frame and sub plate to attach the tslot table and things aren't going back together as expected. On a plus side, removing the base is a cake walk as it's the same as the Sphinx (thank's kyo)

 

So I assembled the machine in two halves (like the Sphinx) and before I installed the two 4040 X axis cbeams, I tried to make sure the Y axis gantry plates were in the exact same spot. I measured everything as best I can and actually it all seems to check out but that's where I am having issues. The bottom frame of the machine is not sliding back in correctly. Before all of of this, I was thinking I need to go back through the machine and square everything up before I run it for the first time. I really just tried to assembled it and didn't focus too much on making sure everything was square.

 

I also assembled the machine with the gantry plates in the middle of the machine (as you see in the pic) but this makes it difficult to reference their position in relation to anything else. Each side has to be in the exact location. Assembling the machine with the gantry plates all the forward or back against the end plates would have allowed for accurate reference with a micrometer. As it is now, I have to use a tape measure to postion them because I dont have a mic that big.
