Thank you for this video. I would love to see a series of maintenance videos including replacing anti backlash nuts and adjusting the router alignment in the xz and yz planes, and tips and tricks for replacing of v wheels.
Next video should be a tramming video specific to the longmill. I was lucky with my first set up and didn't need to tram my machine. After replacing my worn v wheels with a new set from sienci i have not been able to get it trammed as good as I originally had it.
When having the eccentric nuts all the way to the top the loosest position sometimes they will still not turn some of the wheel diameters vary so by putting on a smaller diameter wheel sometimes will help with that.
CHRIS!!!! you are awesome man thanks for this really appreciate it, and for listing to the community. Thanks again for answering my questions at the LIVE event. Question can you put the V wheel on backwards ?I think i either have 1 too tight ro backwards/ when it comes down the rail and reaches abit more than 1/2 way it makes this noise I cant explain like its being forced going to go loosen them up again and follow this Video again Jav -> Javier , Pronounced Haviar ->Hav :)
Hi Jav, you can't put in the V-wheels backwards, but you should make sure each V-wheel has a washer against the gantry. If you send a video of your machine jogging, showing how the V-wheels are looking, to our Contact Us page on the website we can take a look.
Hi Chris, upon adjusting the v wheels, my first job was to surface my waist board, after it was done I had some light black marks on the rails, is this normal or could my wheels be a bit to tight ? Thanks for all your videos !!
Not to worry Al! The black isn't coming from the wheels, rather it happens when loose dust in the air settles onto the rail and get compacted down by the wheels. MDF is the biggest offender because of how fine it is. Give it a clean off as part of your machine maintenance and you won't have any problems 👍 -Chris
@@SienciLabs turns out it was the potentiometer on the Y2 motor. It was not set to 2.2A. The stalling out just happened to be by the feet. After making the adjustment recommended from your tech support the machine now run flawlessly.
You should have a set mount of nm, so users can use a torque wrench to get every wheel at a proper and a matched tightness. (not too tight) is not a measurement where i am from.
I wonder if anyone has tried using steel wheels on the bottom with adjustable delrin wheels on the top. IMHO that would give more rigidity in the Z direction
That's an interesting idea Randy, though we've found that the larger issue with the wheels is actually peoples understanding on how to set their tightness. If properly set, our testing has shown that v-wheels can be equal in strength to lower-profile linear rails. This goes against the popular misunderstanding on the market that linear rails are better across the board, but the results of many tests speak for themselves.

I agree with Dave
But Also!
What to lubricate and which lube is best.

Yes, we previously discovered a small batch of wheels had inconsistent wheel diameters

@@SienciLabs great thank you
My v-wheels keeps getting stuck on the feet on the rails....extremely annoying
Are the wheels tightened all the way up? If you'd like you can send us some pictures at sienci.com/contact-us/

What is the nominal diameter of the Wheel?
You can view all the important dimensions for the wheels here: sienci.com/product/delrin-v-wheel/

Now I'm really confused. Perhaps being able to see what you are doing with your right hand would have helped solve that.
