Routy CNC Router (V-Slot Belt & Pinion)

    Where I live, you can get parts at the hardware store but they are outrageously priced. I went in to get the M3x45mm hex screws and they were like "Oh you want metric? Well that doubles the price. Oh you want hex heads and not phillips? Well that quadruples the price". I mean it was like $1 per screw and I needed like 20 screws. The M5x8mm were like $1.50 each and I need like 75. So yeah I just went online and got a box of 100 screws for $9 and then waited 2 weeks for them to ship from China. But see I already went online and ordered everything from openbuilds and waited 2 weeks...

    Anyway I was going to get the shapeoko2 at first and then decided on the routy because it is more universal. I can use off-the-shelf parts that are reusable. I can throw my electronics onto a routy because it's universal. I can mount my own custom spindle to it instead of a dremel. It has a bigger build area. I don't want to use an arduino controller that comes with the electronics package. So yeah I have a lot of reasons for going this route. For example, I can double the length from 750mm to 1.5m for about $40 and then move those 750mm rails to the gantry and almost double the width for another $40. I can fab the OX parts for almost free and increase the rigidity and working area. This all comes with a little higher price than the shapeoko and takes more work, yeah I realize that.

    So yeah each person is different and don't assume that we all have a cheap hardware store nearby or a windows computer nearby. About the closest and most useful things to me are a junkyard and a recycling plant. The rest is all imported from online orders and shipping is a killer so the parts list is a big deal if you're me.

    As you can clearly see from these photos of my neighbors, I live in E.WA which is pretty remote.

    Well, the m5x8mm are on you, because they are in the parts list.

    But whatever, if you are bothered then YOU provide a parts list. It's perfectly easy to do. So far your contributions are all negative.

    They are on the parts list now because of my contribution to the parts list. They were M3x8mm before my negative contribution. Sorry to be so negative and sorry for not noticing they are on the parts list after I got them added/fixed.

    I disassembled the SketchUp model and tried to add any parts that were missing to the parts list. I'm missing some of the things and will be ordering soon.

    I'm attaching the Excel spreadsheet and was hoping people could add anything I might have missed, so I only have to order once :p Everything I added is highlighted in yellow.

    Finally, I ordered 5 packs of the 6mm M5's to do all the bracket and plate attachments to the v slot and realized they are just too short. From anyone that has experience with it, should I get the 8mm or 10mm (I specified 10mm in the updated parts list but not sure about it)

    My mods are highlighted in red. Your m5x10mm screws are too long and the 20x80 should be 20x40 for one of them. I'm still waiting for my gantry plates to finish the build so this is all I know so far until openbuilds ships those to me.

    The Routy looks like a great
    The Routy CNC looks like a great start for the beginner. Is there a kit that has all the parts/supplies one needs to build this or do you have to order each part separately from the parts list?
    ?

    Once the build is listed as complete I'm sure kram242 will upload all info including a detailed parts list/breakdown.

    We must all understand that this is not a finished build and as he has said, things may change along the way.

    IMO I say wait till at least video 2 comes out before jumping the gun buying/sourcing parts you may not even use.
  8. The Dude

    There is an experimental parts list in the files section. It's missing some parts. Some of the parts you need, like the leadscrew, are not for sale on openbuilds yet. There are no instructions, just some photos and a 3D file. You must order all of the parts separately because there's no kit yet. Many of the parts required are out of stock at the moment.

    If I were you, I'd check back weekly and look at the parts list to see if it's done and then check the website to see if the parts are in stock... if not, just wait another week.

    The M5 10mm are too long and will foul on the center of the V-Slot. 8mm is right.

    You are missing M3 8mm screws, which you need 4 of for mounting one of the motors. (as discussed earlier in the thread)

    You are also missing some M5 grub or set screws, for holding the belts down in conjunction with the t slot nuts. You may be able to get away with normal screws, but Kram uses a grub screw on the video for the belt and pinion example.

    I also assume anyone starting now should order the solid wheels, as they would be better for this build (anyone give feedback on those?)

    You may not need as many 2 hole joining plates as you have now that you have the double t-slot nuts, as I think that was the initial confusion.

    Also, all the stuff to do with the z is kind of dependent on what you are mounting, so the bearings, lock collar, thread etc should all be researched before buying. I am using a spindle with a custom mount, and need an extra gantry plate to get the whole thing to fit. It's also worth considering going M8 on the z axis thread, as it needs to be pretty strong for a decent sized router. However, this needs a custom spacing arrangement.

    One final thing, if you like neatness, then some 35mm M5s (4 of) would be good, as the 40s will stick out a bit when used in step 3.

    According to this page, http://www.openbuilds.com/builds/routy-cnc-router-v-slot-belt-pinion.101/ it IS done and has a completed parts list. Now remember, I'm talking about the Routy NOT the OX which is still not complete.
  11. Chris Allen

    Chris Allen Journeyman Builder

    The parts list is not complete, and I recommend you read this entire thread before considering purchasing anything. You need to research this build before starting!
  12. GrandpawB

    GrandpawB Journeyman Builder

    OK. I guess I'm a little confused. Under the Routy build ~ parts list: ~ Build progress: It very clearly says Build Complete. So are you telling me that in the world of OpenBuild .com "build complete" doesn't mean the build is complete?
  13. Chris Allen

    Chris Allen Journeyman Builder

    The following is true:-
    OpenBuilds have built a Routy and it is complete, the photos document the build, along with the skp file
    Not all of the parts for that are yet on the parts store
    The parts list under the files tab is not an "official" list, it was made by a volunteer.
    A "better" parts list is posted on this thread near the end and is mostly complete.
    You will still need to read the entire thread to understand what is going on and what else you need to understand about the build

    Thank you. For a moment I thought I had somehow entered the Twilight Zone. Keep in mind I am very new not only to this group but to CNC router building. I'm trying to feel my way around. I'm going to ask a lot of questions so please have patience with me. I'm very fascinated with CNC routers and am excited to build my first one. I'm trying to learn all I can. I still haven't discovered everything about this site.

    no problem, ask away.

    Grandpaw B, I'm in the exact same boat as you :)

    Definitely need to do lots of research there first, I've bought several items and am realizing now what is missing. I'll also be contributing to the parts list when I figure out what is missing haha!

    I believe 35mm is correct. I have ordered some 40mm M5's to be on the safe side for length, but I do think that 35mm would probably work. The model seems to have 35mm M5's, but I can't tell. I know for sure they are less than 45mm :)
  18. GrandpawB

    GrandpawB Journeyman Builder


    Thanks. I'll be waiting. BTW Why is everything in Metric? Is this group from the UK?
  19. Chris Allen

    Chris Allen Journeyman Builder

    I would guess because all aluminium extrusion, even in the US, is metric. That and it is obviously an easier format to work in :)
  20. GrandpawB

    GrandpawB Journeyman Builder

    Thanks Chris. Now I'm a little bit smarter. LOL
  21. Chris Allen

    Chris Allen Journeyman Builder

    Actually not all extrusion is metric, but it makes the sums a lot easier.
    And in the UK we technically have imperial and metric, but we are slowly moving over to metric for most things
  22. JustinTime

    JustinTime Veteran Builder

    Same in Canada. Everything the government gives out is only in metric but in construction it's still imperial.

    Oh, and cars coming from the US, they too are still imperial. :D
  23. The Dude

    The Dude Veteran Builder

    Imperial units are absurd. If you don't believe me, go get a tape measure and then measure exactly 5.387 inches.
  24. kram242

    That's what calipers are for ;)
  25. GrandpawB

    GrandpawB Journeyman Builder

    But if that's what you've been taught sense first grade, then the metric system seems stupid.
  26. kram242

    kram242 OpenBuilds Team Staff Member Builder

    To be honest I was raised learning imperial units, but now I find myself using and liking metrics more everyday. It's actually a simpler unit of measure easy to understand.

    Is it just me or does the model show a total of 16 extra precision shims? The parts list is showing two and I'm not sure where they come in but I see a total of 8 (4 on each side) on the y axis and 8 more on the x axis (one on each side of the wheel). There don't appear to be any on the z axis.
  28. Chris Allen

    Chris Allen Journeyman Builder

    Is that including or excluding the one that comes in the bag with each wheel? I have only one on each wheel of my x-axis gantry, and only one on each wheel of each of my y axis gantries. They seem to work fine, but maybe there is something I'm missing?
  29. kram242

    kram242 OpenBuilds Team Staff Member Builder

    I still have to go though it for the parts list but I did put shims between the spacers (including the eccentrics) and all the wheels.
    These extra shims do not come in the wheel kit. I added them to space the plates just a little bit more to insure that and screw heads on the back side of the plate would clear the rail. They may not be needed but it will be very close if not used.

    If you use the low profile screws then you don't need to extra spacers on the two y gantries. I also think the x is fine. (but I haven't attached my x to z) The bottom screw attaching the motor plate is the one which is close.
