That 570mm travel is bang on. My Y rails are 705mm apart, and my gantry plates are 135mm wide, leaving a maximum X travel distance of 570 mm.

 

Hello. I have looked at many cnc routers and I must say I think this is the best version so far. My question is I would like to cut 1000X1000X5mm shapes out of Nylon. Is it possible to make this machine larger to accommodate this size sheet? and if so how do I calculate what size the extrusion needs to be.. Thanks

 

Is it possible? Yes. But I'd say it would be difficult. You can get longer lead screws, but not in 8mm sizes. So this would mean making your own anti-backlash nut blocks for a M10 leadscrew from McMaster-Carr, or coming up with another mounting arrangement. To be honest, I think it would be easier to modify the original Ox belt-driven design to machine Nylon this size. The idea behind the leadscrews is give enough stiffness to be able to machine aluminum and other light metals where belts would stretch or break. I'd think nylon wouldn't require this additional stiffness.

 

I stand corrected.

 

Ok thanks for the information. Going back on what I asked, what is the current estimated "cost" for the standard Ox-Metal?

 

Hi,

Thank for this modification Scematix

 

Hi, Are you still offering to 3D-print the needed parts for the OX-Metal CNC? If so, can you give me a price for your time and/or parts/plastic ... thanks already

 

Twelvepro still has the parts listed on their site for purchase. OX Lead screw upgrade

 

Love the build i was wondering if you had plans in pdf files?

 

Top project would love to see some blue prints to help with designing my own

 

Ive noticed the number of bolts in the parts lists does not match whats used in the construction video. Also some of them are cap screws not low profile screws (eg on the z motor). something to watch out for when ordering parts.

 

Hi guys. I need choose a spindle for this machine, i want cut wood and aluminium. Any suggestions?

 

I'm almost to the part where I will be needing the 3D printed parts. But my Gantry plates and X Carriage plates are 6.6mm and not 4mm or 6mm like the files are drawn up too. My question is, would anybody out there modify the 6mm files to 6.6mm for me? I'm just getting into this and I have no clue how to fix those files for 6.6mm. I do have a local company that can 3D print for me or I would gladly purchase them from someone on this site. Any help would be greatly appreciated.

 

I used a 2.2Kw water cooled on mine for steel / aluminium / wood and I'm quite happy with it. I went with a 2.2Kw in order to get an ER20 collet which alllow me to use tools with up to 1/2" shank. The only thing I'm not sure is if the OX is sturdy enough for the weight (approx 15-20lbs)

HI,

I printed a few OX kits for various builders on this thread. The files CAN be modified but that would be time consuming. Would help if you could figure which parts (names) need to be thickened.

Hello, thanks for sharing!!!
I am new here.
I am planning to build an X/Y Table Style CNC Mill based on OX CNC router milling machine, 2000 Y-axis x 1500 x-axis x 60-Z axis.
ANy recommendations to reinforce the gantry and Y-axis and X-axis to those measures?
what is the cutting tolerance accuracy actually of the OX-Metal CNC?
or any other recommendations?
thanks

 

I found a local guy to print the 6mm parts without modifying the files. The only part that didn't work was the one on the bottom of the X carriage for the lead screw. I was able to make something with aluminum angle. I do want to say that he printed the parts with 30% infill out of PLA. I think they are strong enough for the Nema motor mounts and end lead screw mounts but not nearly strong enough for those little ears on the X carriage lead screw. Seemed very brittle. Just my thoughts.

 

Got the Ox up and running. Everything has turned out great that I have cut so far. I just installed all my limit switches and they will stop the machine if it triggers them. Only problem is when I click on $H I get an "error 5" message. It will not "Home". I'm using the xPRO V3 Controller and Universal Gcode sender. I know I changed $21 to =1. Not sure, but I think I changed $22 to =1. Can anybody help me figure this out? Do I need to change $21 to =1? If someone could tell me which settings to change, it would be of great help. I will check my settings when I get home this afternoon.

 

Hi giarc,

Thanks a lot to reply me and recommendations!!

What if I attach also the X-axis to table?
Why do u recommend use doble 2080 vslot for X-axis (shorter than Y-axis)?

 

Hi! i have a doubt about the Nema 23 motor, which one it´s the indicate? "nema 23 standar" or "nema23 high torque"?

 

The link in the Parts List goes to the standard Nema 23. I use one of those motors on my Z-axis with no issues.

 

Great! Do you use the same model of makita router?

 

No, I use a Bosch Colt. I had that and some other motors carried over from my first CNC build made out of MDF. Makita makes good tools too, I used to sell them when I worked at a lumber yard.

 

In deed I´m thinking use the same Bosch model too. Thank a lot for your help!

 

Is the eccentric spacer in your parts list 1/4" or 6mm?

 

If I remember right you get 1/4" eccentrics to match the 1/4" spacers.
