Thanks Hannibal :P

Thanks for the nice words !

It is really flattering to read comments like these man ! thanks a lot, it's cause of feedback like this i will keep on doing so ! I'm back from vacation, so I'll try to share new info soon..., best regards, Marcel

+RoboCNC Frees- & Graveerwerk hope you had fun and great vacation. glad to have you back. :)

Hi Aaron ! Yes it is coming together, and I don't have to sell the bikes :p (although I hardly have time to ride) . Thanks buddy !

Thanks Gordon !!

Bedankt Ralf !

Bedankt Tim ! Leuk om te horen !!

Bedankt Jaap :) very nice to hear !

Thanks !

Bedankt Pelle ! :)

Thank you vey much ! 👍🏻

Thanks for the nice words ! And glad you like it, and subbed ! welcome !

Hi, thanks for watching and the comment...... Well IYHO you are basically right... And I should have said so in the video.... In my case the bolt holes where CNC made, and really tight, so the are aligned absolutely fine. nevertheless I could have included that in the video... The X axis will be driven by two zero backlash rack and pinion systems (with a double pinion). Stay tuned (ar search for a preview on instagram / facebook)

Follow the one you feel is the best Jannes :) but indeed, you have to assume something, or have a giant measuring table. I have had this advice when talking to a machine builder, who jade done testing on these profiles. They are not ground, but the error is quite low. Anyway, it also depends on what you try to accomplish of course.

i wouldnt "bend" the rails to the extrusion. rails are ground to pretty high tolerances ; extrusion can be off over .001" per foot

The y axis is the gantry, 80x160, but watch the other videos for more info on that..

I do not agree that that would be an upgrade... The machine is making its money, so no need to upgrade to a new model, For me its about using the machine not building it..

Thanks

No these rails are much better.... The first time I went for cheaper parts...

Nice to know. I want to build a CNC my self and I was thinking going in the same line you did the first time that until before I saw your videos. So thank you very much for sharing your experience. I think everyone would like to see your X2 in action =D

Listen to the videos..

And where would you put the precision straight edge on..? where is your assumption.... (By the way, i talk about this subject in the video)

@@RoboCNCnl I'd put the straight edge against the rail. And I would not set the rail directly on the extrusion. I'd have it on a piece of flat stock and that would set on the extrusion.

Hi Phil, For your work you can debate if you need a CNC router. Just rails and a router to flatten everything would be an option. Anyway, take a look in the rest of my videos to find the answers to your questions. The machine is build in house.

@@RoboCNCnl Hi 👋, thank you for your reply, yes I have been looking, very interesting, if I can get the The materials I think I might have a go myself I’ve seen lots of bits and pieces online, I did say something I think it was made in Canada that was very interesting the other day on KZfaq good Inc three devices a router head , 300 wide planer , 300 drum sander . With a very heavy pricetag I think It was over $40,000. But this will be a project for later in the year as I’ve got to finish doing my garage floor and the roof on it, it’s more a renovation project than anything else, Thanks for the info, And I did manage to find you works details you’ve got some interesting projects, stay safe, PHIL FROM THE DARK SIDE OF THE MOULIN FRANCE.

@@RoboCNCnl I forgot to Ask you a question I just went back into your tutorials on build or router table, Why did you use a rack and pinion system, Instead of a ballscrew. PHIL FROM THE DARK SIDE OF THE MOULIN FRANCE.

Listen to what I say in the videos Phil, it is all explained… in short, long ball screws will not work due to any inertia and vibration.

Yes sir... these extrusions are expensive... Just have to find someone in your area who needs them ofcourse :)

MySchizo I use dry lubes to prevent dust from sticking. This reduces life of the bearings, but that’s the concession to make. There is no way to prevent dust from getting their.

@@RoboCNCnl looked at the design of cncrouter parts. They have the linear guide mounted on the side of the extrusion and cover is attached on the top of the extrusion. Essentially covering the linear guide from direct dust.

please view the videos and listen to my explanations.... Plans are shared..

The problem is that i do not know English and i do not speak it, i´m from Spain, sorry for the inconvenience

No problem, find the download at : www.robocnc.nl/?p=5368

The profile is the straightest part in the build, so bending the rail straight. And then making the next one parallel.

Thanks, but no, im not selling them

Good job !

After 12 years using CNC I'm quite sure i can deside wich axis i will use as X and Y :) . But since you are here to learn.... It's totally up to you, or the way you operate the machine... X goes from left to right, and Y moves away from you, so from where do you look at, and operate the machine..

I watched all your videos, I did not see the machine while its running as you said it depends on the orientation you stand front of the machine. Anyway its good job go ahead man.@@RoboCNCnl

I can not help you based on the video, sorry

That was not what i said... I said "everything you see here is about 150kg" So the base, and the gantry, plus all of its parts..) Btw, do you think your decision of filling it with sand (a lot of extra inertia) is a smart thing to do? I think It would only be a good thing for the base (non moving parts).

+RoboCNC Frees- & Graveerwerk ah ok. I filled all my extrusion with silica sand, the sides, slats, risers and gantry and it was the best thing I ever did. it's taken all the harmonics or of it. the extrusion used to have a ring to it, now it's solid and doesn't ring and it's taken abit of the vibration out of it, to combat the inertia I just adjusted the velocity and acceleration in mach, it still works fine at 25m per min for rapids, I used epoxy to cap the ends so if i didn't like it I could just drop through the epoxy and pour the sand out but I will be leaving it as it performs much better and dampens the machine.

Yes I can imagine the extra mass will change the harmonic frequency for the better. But I doubt it's the best thing for the moving parts like the gantry. Most people talk about there G0/rapid speed, I personally don't care about that at all, when will you ever machine at 25m/min? The acceleration is very very important for me. especially for 3D work this is where the time gets lost... Anyway, If you had vibration issues you have to comprise, but i hope I don't have to...

+RoboCNC Frees- & Graveerwerk I never really had vibration issues. I just wanted to bulk it up. I am running nema 34 on all axis with a 3:1 great reduction, I agree about rapids but I do cut some things at 12m per min and it's nice having the extra mass when doing that, it's made a huge difference in milling aluminum.

I'm not that strong :)
