Whats the longest 20x80 you could get as a special order? like 2, 2.5 meters? Because then you could build a very inexpensive 4ft x 8ft router for working sheet goods

Very nice kram! Definitely looks a little beefier than the SO2, still working my custom design but those solid v-wheels are intriguing.

I'm building a 1m by 1m Routy-OX hybrid all in black I'm just waiting on some more vslot and bolts.


->By the way the parts list for the routy says 3m bolts so I now have 5 bags of useless bolts

Thanks

5m X 10 mm, also you will need 8, 5m X 40mm for the Z spacers and the X axis

->I'm on my 7th order trying to find all the missing or out of stock parts so expect to be short some parts.

I am also going to build a Routy-OX hybrid in assorted colors. Just to be different. The biggest difference is that I intend to use a fletch beam for the X axis and extra supports on the Y axis. The fletch beam will be made up of 2 80x20x1500 pieces with a 1/8" steel plate down the center with all the pieces bolted together so that the beam will not flex no matter what size of router/extruder/plasma cutter that I hang off of it. I also like the solid wheels. They should decrease any flexing of the unit when built.

I am curious about something, I see the Routy is controlled by 3 drivers. There are 4 motors. Are the y axis motors being shared by 1 driver? and if so, can most stepper drivers operate 2 motors?

I know with my controller hobby cnc I was told by the owner that each motor needs it's own ports so I'm going to have to use a 4 axis driver because it have 4 motor drivers on it. I hope this helps. I'm not sure about the boards that mark carries

This is very true and I wounded the same. Well I guess try to slave two together on yours and when I get mine built I can try running them separate. Then we can compare. I'm very curious.

When do you think that you will have the parts list available?

Mark,
I am eagerly awaiting you to share the Sketchup model for the Ox... So that I can order parts.

Amazing looking build!
Quick question for you.

Will there be limit switch present in this unit? are they even necessary?
Want to build one as soon as those plates are available to purchase!

Thanks.

On the issue of the 3-4 stepper printer controller. You can use a 4 port controller to drive X, 2 Y's and a Z axis system. The only requirement is that the Y's be driven with the same enable, direction and step signals. With 2 drivers tied together the only real problem is getting the motion direction set correctly and this can be done with the wiring to the 2'nd motor as it has to run in the opposite direction from the 1'st motor. To check that the motors are correctly wired up hook them up first and verify the direction that they are turning before connecting the timing belt and if the motors are not rotating in opposite directions then reverse one of the loop pairs on one of the motors to correct this problem.

You need limit switches on all 3 axis for repeatability. They are used to guarantee that the machine know where X = 0, Y = 0 and Z = 0. If you have to change bits or change files or any other interruption in the creation chain of events to make your object then having a precise origin is necessary for that to happen.

Looking to do a build. Curious why you decided to not use the metal wheels? Noise? Wear? Are the plastic wheels solid and without slop? Looking forward to the parts list. I have the shapeoko2 coming, but am already wondering if I would be better off to just start with an OX instead. Thanks for the videos.

Metal wheels will cause surface erosion on unhardened extrusions (colored extrusions are not hardened). With the different types of builds possible you should be able to create a wheel support design that will work on the existing V-slot design. Mark can respond on how much weight the plastic wheels can support.

I will be installing limit switches on my build. My build is based on OX with many stolen ideas from it. >

My current huge 300+ lbs all wood CNC router has limit switches and they help reset and continue a cut. But unless they are really high quality you will be out a few thousands many times on that. The little mechanical switches are not "super" repeatable. Only to a few thousands usually.

I'm so glad I came across this site! I was doing research into making your own cnc machine and after a lot of looking at different websites, pictures and links I came across openbuilds. Its an excellent site with a great range of parts in the store.

I have been watching the OX build on the youtube channel and would love to have a go at making one. I know someone mentioned earlier in the thread about whether you'd be selling the custom plate parts used in the OX, It would be brilliant if those became available to order as I will definatly be getting the parts to make this in the future.

I am looking forward to the next video explaining how the electronics and software work. I love the mechanical side of things but unfortunaly I haven't got a clue when it comes to electronics. I'm hoping that the community can assist any people like me in this area in the future.

Keep up the great work you are doing. I will spread the word about openbuilds. It took me a long time to come across the site so I'm wondering how many people are missing out on this.
