Awesome machine man! This is definitely one of the best home built CNC routers I’ve come across. Can’t wait for the follow up video to see how it performs! Keep up the good work

You are insane brother, that is really really good precision.

Adding sand to your top extrusion would be good for absorbing vibrations. But at the same time it will increase substantially the work load for your Y axis motors. Also it will make your machine top heavy. Time will tell! Good improvements you made. They will pay off for shure. Keep us posted!

I appreciate your time and effort. Thanks.

Brilliant work this. You machine looks amazing. Keep up the good work.

Thanks you share all these issues

Hi Mario, My router is only 430mm wide and I see a reasonable amount of play because of a single ballscrew on the Y axis. I believe that lengthening the supports for the gantry can also help but then you have shorter travel. 2 ballscrews would be the way to go, you would need to have 2 proximity switches through your interface board so that Mach3 (or what ever you use) can zero them to parallel the gantry to the Y axis so there is no "crabbing" that increases friction on your linear slides. That would obviously mean an new servo motor and driver, possibly an upgrade to your power supply also. awesome work! keep it up!

Continuous, it's really your improvement.

Nice job!

You have to tell me if it improves the performance :) I am as you know building quite a similar one myself, and i have had the thoughts about filling em up.. so if it helps you, i might just do it right away :)

I was thinking about putting concrete with rebars inside of extrusions to increase their rigidity. Do you think it can work?

Can you make a video showing how you made those gantry supports.

Muito bom, máquina muito forte.

where do i buy this tool, very cool to analyze like this, this is called a command right? there is a video explaining how to use it

11:36 Thats just perfect. M really impressed. Please share how u brought it to that perfection. Second thing, do u think single ball screw in the middle is good or 2 at the sides are better for the Y ?

Everything look very good. Except the x-axis ballscrew is located at a little bit lower position. It may cause the assemby inclined especially when under heavy cutting force.

Did you make those support arms yourself? Wow, those look amazing!

where did you get the sides from??? they look great

I don’t know how long it took to align your linear slides but great job!

Very nice!! Where did you get those extrusions??

How much do you think it helped moving linear rail from the side to the top? Seems side would be better with less chance for debris issues.

Nice work and great channel! I have the 2.2kw water cooled Chinese spindle on my machine. You should offer a cooling reservoir for this spindle with a built in radiator. Bet it would sell well.

Did you ever get this working? Can you please update the links? Im looking for the rails that you filled with sand in this video.

Did you cut the gantry and base supports your self? I will like something similar to yours. I just bought my linear rails.

I am in Ecuador, what profiles are they and how thick is the profile, to find the reference for South America, can you help me with the data, please

Did you drop the gantry @4:04?

A 2# spray foam would accomplish the same vibration damping with out the added weight in the top rail.

That thing could survive a nuclear explosion

Your new gantry plates are awesome! Are you concerned about getting debris in your linear rails? If so what are you doing to fix it?

Cool vid! Can you explain your reasoning for choosing sand filled vs something like concrete filled?

did you build loose bearings on one side of your spindles? The expansion forces when the spindle is warm are not to be underestimated. this bends screws or even the spindles around it should always be created a way to expand. loose or slightly preloaded bearing on one side and fixed bearing on the drive side. I hope you can read my English while is not the best. When build a selfmade machine than is that find never an end while all time is some that can be better.

And when your machine swing to much than test it with a little bit higher or lower HF Spindle speed or a short tool that helps most time and cost nothing money only time to find best for your machine

Are those alu extrusions machined?

This is one serious piece of machinery, go any bigger Hass is going to loose sales.

yo can you make me those z aluminum uprights? the supports? I pay $$ please~`!~

Should concentrate on feed rates... When you say "stiffen" you are on the wrong track.

еще и стол надо сделать тяжелее

You after .0001 accuracy? Cause the extrusions Illustrated are good for most cnc's. Way better than an x-carve or competitors. Just pay for a better CNC.

Sand + Epoxy

You need to loose weight...not add weight. Adding weight is a fast way to kill ball screws

this video says: I am rich and bored and was i said " i'm rich "?...

It looks nice. But you can't call this homemade. Also... you've spent so much on it...you could just buy one already made.

I don't understand this. You spent thousands on dollars on the frame. It was obviously much more than $1000. You spent more than $1000 on the Clearpath servos. One of those is about $500 and you have 3. And then you buy eBay ballscrew for $120 ? You thought it was not important part of CNC ? And when you saw it was crap you repeated the mistake, and you have bought it again ? Something is fishy with your story. And you use 25mm rail ? Have you seen its parameters ever ? Its HUGE overkill for a weak 2.2kW 0.8Nm 24,000rpm eBay spindle motor. Those rails can hold and move a 2.5 tons SUV or a little truck easily. I mean one rail, with one block. 2 blocks 2 rails => the Y axis would be able to move about 10 tons. Your spindle motor can't handle more than 400N chipping force. 100kN > 400N ??? Huge discrepancy again. And where do you buy those aluminum sheets ? You always link McMaster-Carr. Sure OK : 1 piece of 1 1/4'' thick 12'' x 24'' 7075 alu plate is US$ 995 at McMaster-Carr ! The 6061 is about the same. Although the piece in you hand looks bigger than 24''. Never mind. And you need 2 of those for the 2 pillars. Are you talking about a $2000 upgrade on those aluminum side pillars ? But you have bought $120 Chinese eBay 1605 ballscrew for saving money ? Hmmmm. You seem unreal sorry to say. Is this a pure advertising video, that was the only goal ? Be honest please.
