I’m about to pull the trigger and order all the parts to build the OX, but I’m wondering if it’s possible to mount an acme lead screw with the 8mm rods on the X and Y extrusion? Would this increase accuracy? Also, if I do go with the belt system, how dependable and how accurate is it?
The R7 from Smw3d is designed to use acme lead screws… it might be less hastle to just go that route than redesigning the Ox gantry plates
If you don’t want to go to all the hastle of sourcing every piece and part for your build smw3d offers this as a kit and will have pretty much everything you need (besides the tools to assemble) come in a very well packaged box http://www.smw3d.com/r7-cnc-diy-kit/
I appreciate that Alex. My problem currently is … if I order from SMW3D, I am forced to get items I don’t need… IE. the 300 or 400 watt spindle. I already have a Dewalt 611 that I only need brackets for it. Also, if I order directly from Openbuilds.com, the billing sheet shows I will have to pay $200 for shipping, whereas, if I ordered from SMW, it would only be $41. Things like this are the reasons I’ve been so hesitant to pull the trigger and purchase.
The ox metal, does just that. 8mm lead screws on the ox platform. http://openbuilds.com/builds/ox-metal-cnc-router-mill.3681/
@Gimp_Geek I’m pretty sure the r7 comes with an 800w water cooled spindle
@Gimp_Geek we can drop anything from the kit you don’t need chief. Easy breezy.
@Alex_Krause I’m going to have to put you on the pay roll… Haha.
On the ACME, yes it is a good drive system, good observation.
@Brandon_Satterfield I can verify that @Alex_Krause works real cheap! Definitely put him on your payroll.
So far with adding parts over on OpenBuilds Store, I’m up to just under $800 without Plates, and Controller. Maybe a couple small items that they are out of currently, but I think I can get it all for less than $1100
Well, maybe around $1200 now that I’m thinking about wiring and cable chain
Awesome, let us know if you need any help. Great community here!
@Brandon_Satterfield it looks like I’m going to be sending about $300 of my order over to you at SMW3D for things I can’t get on Openbuilds and the plates of course. Thanks for your help
Ok, I’m very nervous after spending that much money, but I just ordered all the electronics and plates from SMW3D and the frame and hardware from OpenBuilds… Once they arrive, I will be building my OX. Thank you all for your input and all the info you have put out for all of us to review.
