So new board ordered then if the A axis driver is toast. Poo...

 

That's why I went with the gradus m1 pro. I could replace the drivers if I fried them. They fried pretty easily but were easy to replace.

 

I have a laser build I intend to start within a month or so, so I'll consider it for that.
Reading the xpro troubleshooting wiki, I've also ordered replacement pots in case it's that. I did mess with them after all.
Thanks guys.

 

Mark,

has anyone gone thru and completely update the OX machine with all the new drives and spindles out there?

What exactly do you mean by new drives, I have an OX that I have enlarged, changed the drive system from belt to complete lead screw with nema 23 steppers. And getting ready to upgrade the z axis to be able to support a 2.2kw spindle. The Ox base platform is an outstanding platform to to start from and expand easily. Wish Mark would sponsor my next build LMAO!!! Any questions let me know I will be glad to answer them.

Scott, looking for maybe nema 34 motors, yes 2.2 spindle, i'm looking at building one of these in a 4' x 12', i want to cut alum sheet metal panels. looking at the upgraded steppers just because i really would like to do some aluminium parts other than sheet metal also, stuff like the side plates, etc. was just wondering if anyone had added the best of the best to the OX build, there are so many new components out there, just hard to sort thru them all. Thanks, Ray

 

Scott/Rick, Thanks for the input. Another question, is the standard OX system capable of cutting small aluminium parts, say 1/2" thick 4" x 6" misc holes and slots, etc? (assuming you changed the router)... the big machine is was talking about would only need to cut .060 sheets of aluminium, i was just trying to combine both machines into one. is it realistic to assume that the OX would cut the .060 aluminium if it was beefed up making it more ridged & changed out the router?

 

Yeah getting into a system that big is gonna need some heavy duty equipment. Look at 8020.net I believe that is the site. You can find much larger t-slot equipment for a much sturdier setup. The small stuff the ox has just isn’t gonna get it done for what you want to do.

 

Yes the ox is capable of doing small stuff with pretty decent accuracy.

 

Thanks for the Input !!

 

A 12’ run is a long run for a belt system at all. You could do a chain drive system especially if your gonna use nema 34 steppers, and it would be a whole lot cheaper than trying to use lead screws. The c-beam is a good choice as long as you use another beam to the rear of it as Rick has mentioned. It could all be done, I would seriously be questioning the accuracy level it could produce. I think this would be an awesome project for openbuilds to test and try to market if at all successful. Seeing as they have all the resources at hand to tackle a project this size. Could be a decent money maker if successful!!!

 

I've been buying parts a little bit at a time to build a 1000 x 1500mm (about 40" x 60") OX for CNC and laser etching (I already have my laser working and have the enclosure).

Now I'm ready to get the parts for the mechanical build. I'd like to get a kit rather than going through a long list and buying everything separately. makerstore.cc has a slightly modified OX that seems to have good build documentation but I don't know where they ship from or what their reputation is. There's an openbuilds parts store but no OX mechanical kit. Of course there are a number of eBay sellers.

Any suggestions from experience?

 

Thanks, that's quite helpful. It looks like list might be my best option.
I'm comparing Workbee to Ox and it seems like the main difference is the use of dual leadscrews for Y rather than belts. I'm assuming that accounts for the higher cost and probably also avoids belt tension and other issues.
Are there any other major differences between OX and Workbee?

 

I have another question about spindles. I have a fairly hefty handheld router (Craftsman 1hp variable speed plunge router) which very neatly comes out of the handle / plunge assembly and the rack gear removes with two screws. It's rated at 11A at 115V and is fairly heavy (about 2kg). I'm wondering if it may be a bit too heavy and/or overpowered for the Ox, or is that fairly normal? I think it's one of those things that will become evident when I run my first cuts in relatively hard wood where the router will want to run away (my experience with handheld router work is that it's a function of bit size, bit sharpness, RPM, and wood).

I was planning to run the router through a 10A relay so I can turn it on and off (with a separate relay for vacuum). Eventually I might upgrade to something with speed control if I end up doing a lot of woodwork.

Are there good resources for "first cuts" with recommendations on wood, bits, rotational speeds, feed rates, etc on DIY CNC router builds?

Of course I mainly want to do laser etching but I'm also looking forward to trying to do some artistic woodwork...

 

I don't have it in front of me but I probably underestimated the weight, and had I bothered to look at the cover of the manual when I took it out of the bag this morning I would remember the rating. 1 3/4 hp sounds about right. The cylindrical motor housing is around 5 inches.

Sounds like I need something (quite) a bit lighter, and can probably get something with wired PWM speed control.

 

? On this build could i update to a wider size timing belt to make it little more stronger... Try to cut alluminum 1/4"

 

What is the best way to stiffen up the OX CNC? here is my setup.

 

Thanks for the quick reply!!
No it doesn't have support I need to take care of that. Help me understand what you mean on strengthening the x axis! And what can I do with my z axis?

 

i just double belted my machine and what a differense i can now cut circle befor they were ovel now iam looking to do new plates so i can but c-beam on it just looks stronger...

 

I have a ox 1000 x 750. put on a new sparks xpro v4 driver. Where can I find the parameters to fit my machine or which open build is close
