I'm not convinced the concrete will adhere to anything well enough to provide meaningful strength.
I think you should cast a concrete block, heavy on the rebar, and drill a series of holes for...
This is true, though other axes can slightly change that. 100mm in Y and 200mm in X and Z seems like a good compromise to me.
I wouldn't sacrifice rigidity for upgradeability, as the frame will...
The flatness across the flange is not adequate for profile rails. They will not be coplanar.
My mill is aluminum because the cost of the material plus the cost of work to get it flat was cheaper...
I think this machine would be capable of gently routing out 1/8"-1/4" aluminum to make side plates to reinforce the joint. It still won't be amazing, but should be adequate for light work with...
Credit card companies seem to have no issue reversing charges for things that were not delivered. I no longer trust paypal to do anything competently.
It's been a while since I was in the market for it but pretty much any AC input driver that can be set to the proper current will be fine
What size rails? A block that long is probably meant to be the only block on the rail, and may have two tracks of bearings per race, or just a much longer loop.
I have found that Nema 34 motors tend to be very lacking in power, because of the high inductance. To use them properly IMO they need to be driven with several hundred volts. Otherwise a typical Nema...
Doing some figuring I'm going to up the sides of the enclosure wall to 1/4" aluminum, which will add significant rigidity to the weak axis of the machine.
Those cylinders only lift 50 pounds each....
I have a massive press brake at work that is fine but is very slow and cumbersome for the small parts I tend to make. I would like to make a 600-1000mm wide press brake that can press 20-30 tons at...
That is a good point, but my machine has no base to reinforce too. It's held from the sides by the 3mm aluminum sheet metal enclosure.
I have decided to route my cables differently so that I can machine a beefier reinforcing plate and swap it out later. There is a limit to what I can do with just that one area, as after 2.75"...
Yes I have, which is why the plate is doubled up at the columns.
The machine as shown has the table all of the way down. during typical use you would typically try to have it as high as possible,...

Hello all, this is my first post on the forum but I've read a lot of threads here.
The machine I am building has a work area of 300mm x 300mm x 200mm and is designed to cut aluminum with ease and...
I've found the reason I don't finish many machines is because of electronics, despite that being my specialty. So I've decided to build projects with more modules such as stepper drivers and off the...
