You can.. and if your machine is 100% completely square.... probably won't be a problem. If you have wired the limit switches in parallel like it appears to be in your diagram, the machine does not know which limit switch is triggered on each axis (it just knows that one has been triggered). However, if the machine is not completely square, and the side of the axis with the broken limit switch is closer to the end of the the rails, it could in theory crash into it (but it would have to be out of square by a decent amount).

 

is it important that my cnc table must be on level? And also Ox table has 2 bridge in the middle and look like I won't be able to have a deep carving option. Is there any way to figure out depth cut size? can I move or remove the middle bridge support brackets?

 

Not really level BUT IT HAS TO BE 100% FLAT! You can't have one corner higher/lower than the others.

If your table is flat, as I said above, and you'll screw the frame to the table properly, then you could remove them.

The OX is an outdate model. Look for more up-to-date designs.

 

I know the Ox is old news but I hate to let it go to waste.
I built my Ox is March of 2015 and it's cut many projects for me with little issue. Since my last move 4 years ago, Ox has been collecting dust and my C-Beam XL is handling most of the work. However, I now have the need for a larger format machine but I'm over the belts and pulleys. My question is regarding linear rails vs linear rods and which is more suited for a machine of this type, I'll only be cutting wood on this machine. Are two linear rails on each side of the Y axis needed or would a single 20mm rail with two blocks work? My tool will be a simple router of some sort so no super heavy weight on the gantry.

 

I think whichever is cheaper overall. There is considerable cost and effort in the upgrade. I recently upgraded my workbee to linear rails, and it was over $500.

 

I use linear rods. I have one on each side of the Y axis and two on the X axis. Each rod has two carriages/blocks. I used the 16mm rods. Plenty strong and cheaper. Two rods per Y axis side may be better but I didn't want to make the machine taller than it is already.

 

I am getting to understand how to operate my ox machine. It is a good bargain for me to play with it Having great fun so far, drawing generative content, cutting generally soft timbers but its struggling to cutting melamine, other than that cool beginner machine.

 

Mark Carew, Being a total newbie myself about 3 years ago I bought a chinese 3040 to learn about cnc. Its was alright until I updated the firmware and it turn out to be a bad clone of the Plant CNC controller. So basically I was stuck with a controller that would not recognize the touch probe anymore. So I did some searching and come across this site and I posted the 1st time and Peter Van Der Walt turn me onto the black box. So I saved up my money and bought one including power supply.

I had it hook up to my 3040 down loaded the software and mess with the 3040. Well I wanted something bigger since I have a woodworking hobby and I wanted to make a some money to support my hobby since the price of wood went up and I am on a fixed income.

I watch your videos on your OX cnc build and I decided I will find a way to get the parts to build one> Come across a site called SPAM. They had a OX cnc mechanical kit 750mm x 750mm and I already had the NEMA 23 stepper motors and even with shipping it was over a $100 cheaper than buying all the parts separate. So I did a little more research and checking reviews and they seem on the up and up plus I used paypal for just incase. I have a makita 700 router to use on it. Just need to get some a few more stuff like the IOT switching relay power strip.

 

Hi, I just received a used OX 500x1000mm with all the four motors and the spindle (with 48V spindle power supply) but without any control electronics.
Can anyone suggest me the cheapest and easiset way to get it running?
I mean the control hardware and software.
I've heard of the black box thing and I'm sure it's great, but it's way over my budget right now.

I would really appreciate any help!
Thanks, Carlo

 

I've tried other systems if you can afford the black box then it is the easiest and best to set up the others are ok but yo will have to do more setup with the arduino

 

Thank you all for your aswers!

Could you please elaborate a little on what you mean by "reliable" stepper drive?

I already have an Arduino. My motors are rated at 3A/Phase (Nema 23 Wantai 57BYGH627).
I also have one of those parallel port cnc breakout boards around (to connect to a pc).

Do you think a set of cheaper motor drivers like the TB6600 could do the trick?
I'm really on a shoestring here...

Also, how would one control the spindle in an Arduino-based scenario?

 

Ahah, ok I get it. Thanks for your wise words.

 

Hi peeps I purchased a second hand CNC and was told it was a workbee but I think it might be an OX instead . How do I check what I have got?

 

Is it using C-beam or 8020?

 

Hi all,

My OXCNC has been running reliably for years, know it's out of date, but the old dog hasn't let me down yet....

I was just upgrading to the latest version of UGS and it all seems to work except when I manually move the x,y,z axes it moves in a weird stuttery way - ie instead of moving smoothly 10cm, it moves in hundreds of tiny increments - it also moves waaaay slower.

It feels like some sort of setting needing tweaked?!

 

Sorry for the daft question, is this under $$ in UGS? I can't recall seeing it

 

Ah right, I might try openbuilds then - not wedded to UGS, slightly strange they wouldn't have this built in?!

 

Hi guys ive just stepped into the world of desktop cnc, i know its old but ive just purchased an Ox , the guy who i had it off as added some strange wooden parts to it. Is there anywere i can get pics or a build page to see how this should look. Do i need to know anything about it before i start learning ie upgrades ?. the Z up n down are very noisy i.e. vibrating so not sure what that is yet

 

Heheh, sounds like a bit of a modded version then!

How about this:
