This may or may not help you but figured it was worth sharing.
I started down the multiple offsets path and couldn't get it right every time, so I went with a simpler philosophy which is working...
Very interesting thread thank you - I've learned a lot.
how did you go with the bent ballscrew? did you straighten it?
Any more progress on this one? I am looking at converting the same machine
Family holidays always slow down the progress!
Peter, it was no typo, I am indeed looking at 2525 ballscrews, which should give me around 25m/min rapids with the screw at 1000rpm, and...
I may cop some heat for this but I’m going to give you my opinion. I am also a Millwright, but only 10y experience, and in Australia Oil & Gas
Your options are all based on budget. You said $2500...
Whats your experience level with CNC and budget?
When I get a minute to sit down I’ll take a look at the FEA, I’ve done it for single parts, but not assemblies so will have to have a play with it.
I am going to start putting prices together for...
Gerry,
- Thanks for the link, I had read that thread about a month ago, maybe will run through it again and compare the findings, there is a huge amount of info in there.
- Good to know about the...
Of course someone has to play devils advocate!
You make some valid points, and I have certainly considered most of your thoughts prior to this.
1) yep you're right on the money, I'm budgeting...
Ok, I thought that might be the case. What's your view on how to run the servos? I can only really go off what I've read, and the general consensus I have seen is that Step/Dir is OK, but the...
The buildbotics looks interesting, Though I can't find anywhere what type the controller is: Mach/LinuxCNC/GRBL/proprietary etc.Also I don't like the web based interface, it's an interesting concept...
That’s good info thank you Peter, I will see what plate I can source for the Z, I remember seeing some guys use thick steel tooling plate that’s been ground or machined on both sides, I will look...
So I've continued on with the gantry on raised sides design, It looks the most rigid so I will run with it.
There is 290mm from the bottom of the gantry beam to the cross beams on the bed, I'm...
Thanks for the detailed write up Pete, It has given me much to think about for my router design.
Whats your target price for the Maximus? and what is your planned level of assembly? i.e...
Ok Cool, I'll bump it up to 200x200 and see how that looks. should I increase the thickness of the beam or is there not so much benefit in that?
The design that I think I will go with (first 2...
Thats awesome info, thank you. I didn't expect to need reduction as I didn't think those rapids would be possible. What sized pulleys and belts should I look at for that sort of torque/rpm? I'm...
Hi all,
After a few years with my Shapeoko 3 XXL, it is time to build myself a more serious machine. I have done considerable reading on here and other sites over the last year or so and though I...
First of all, thank you for sharing, your build looks extremely tidy and well thought out. Though we cannot get the Precision Matthews machines in Australia, I am looking at buying a similar machine...
Very interesting, thanks for sharing!
This is great reading thank you Gary - I almost pulled the trigger on the FLA Saturn some time ago, but the stories of warped frames and quality issues scared me off..
Your design is quite similar...
Watching this with much interest - thanks for going into such detail.
I'm looking at a similar machine with DMM 750w AC servos, and a 1.8kw DMM on the spindle - Still deciding whether to run under...
I Hope they can sort it out for you, otherwise it pushes you a bit to install linear rails... I have seen a few guys get gibs made but I'm not sure if there are people who can do that locally for you...
Looking forward to seeing you do this! I'm in the early stages of planning for a similar machine with similar servos including the spindle.
Will you look at putting linear rails on this? My plan...
Any update on this? thoughts or comments on the purchase? I'm looking at similar machines
I like those screensets, are these built under QtPyVCP with the help of Kurt and Turboss? I have been using LinuxCNC for a few years and just got started with making my own screensets, I can't...
I've got to say, I am seriously impressed with every single part of this build... I take my hat off to you, your design is very rigid and simple, you've been open to design input, obviously very...
Thankyou for the info, I appreciate the honest thoughts on it. It sounds as though there are a few "fit and finish" type things that could be done better, but for the money it is good value.
I'm...
I am hanging out to see this machine at work! How are you getting on with LinuxCNC? I use it with my cnc router running steppers and a G540/Mesa 5i25(obviously an easier setup than yours), it took me...
I have the XXL version of the Shapeoko 3 https://shop.carbide3d.com/collections/frontpage/products/shapeoko-xl-kit?variant=42721938758
And love it! 800x800 cut area, it has MUCH beefier rails and...
