    Hi, I was wondering how is the cnc machine build going? I was curious if you have got it going to notice if the MGN12 alignment block for the rails works good or you do think you still have to use dial indicator?

    Corey, well... it is going kind of slow. I did get all of the hardware for attaching the rails and they are now on. At first I tried a 3d printed guide for rail alignment but was not satisfied with the result. So I made an aluminum block that I bolted to the extrusion, this block has an adjustable screw for setting the rails. like this, there are t nuts holding it on so you can push the rail against it then snug down the rail

    This worked very well, I did check the rails with an indicator afterword but they seemed perfect. I think this measuring step is not really necessary but it was reassuring to confirm that my alignment jig worked.

    Once I set and tightened the top rail I loosely assembled the bottom rail, side plate and rail blocks. Then I slid the side plate back and forth and snugged up the bottom rail and blocks. I figured that this would align the bottom rail to the top rail and as far as I can tell it did the trick.

    That aluminum block and screw are brilliant. I was just trying to come up with something to do the same thing, but you did it for me. Awesome! thanks.

    Good idea! Thanks for sharing. I was a little on the fence about 3d printing the guide but I was gonna try it. Only reason why is I know my 3d printer. And I figured I print it up and something would be off. But I like your idea better. Glad I asked, I am still sourcing parts so haven't got my rails yet. I have had to redo
    Z axis plate so machine is apart right now. But as soon as I can cut aluminum reliably I plane to make some plates and upgrade to rails system or just start another bigger machine. Thanks!

    Nice update! Machine looking good. I also like the thrust bearing and washer Idea! Did you push the motor drive coupler just snug?

    Thanks Corey. Yes the motor coupling is 'just' pushed against the thrust washer. I have cut a few projects with the machine so far and everything seems to be working well.

    Those should work, they look exactly like the ones I used.

    Where can I get linear rails for this project? I am converting a workbee1010 to linear rails. Chris is sourcing the plates
    Deluxe 2" taller Linear Rail Sphinx CNC Plate Set (seen at Openbuilds) | eBay
    , so I’ll need the rest of the hardware including screws, nuts and everything else. I’ve never bought linear rails from eBay or anywhere else for that matter. Don’t want to get stuck with junk specially since installing this upgrade takes a few hours to do. Any suggestions?

    Myself and others here have purchased these. I bought three sets, but could probably got away with 2. I use a top and bottom for each side of the y axis. I plan to cut another set to 1000 mm for the x with the leftover pieces for the 500 mm z axis. I am doing a homebrew high z mod to mine using the Openbuilds high z kit. I did have to order 4 extra bearings for the z.

    I got the rails I used for this build from the following links
    https://www.amazon.com/gp/product/B07Z5NKF42/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
    Machifit MGN12 100-1000mm Linear Rail Guide with MGN12H Linear Sliding Guide Block CNC Parts Machine Tools & Accessories from Tools on banggood.com

    I did have to spend some time cleaning the factory oil from the bearings and rails and then re-lube them, but they seem to work well.

    The plate set I got from Chris had spacers that work with the 12mm MGN12 rails, so you will have to verify what height of rail and bearing works with your set up.

    Thank you guys. Any do’s/don’ts when cutting the linear rails to size? Thinking of using a jigsaw with a blade for metal. I don’t own a grinder but I could borrow one.

    I was just going to use a sawzall with a metal blade and if that doesn't work, an angle grinder.

    Hi again, I wanted to bounce a couple of ideas by you guys that have gone thru a similar upgrade. Seems like with Covid, linear rails are hard to come by. I checked the Amazon link and they were out and the banggood are partially out as well.
    I came across this vendor in Texas
    ZYLtech Engineering LLC that has the rails. Adding rails and plates, I am close to $720. I also came across https://www.cnc3d.com.au/ which sells the entire kit using linear rails (a bit bigger blocks I think) with all the bolts, shims and others misc for about $920 delivered. I was wondering if $720 plus all additional hardware is the best route. Anyone has experience with cnc3d?

    I cut my rails with a grinder with metal cut off disc
