I think without buying specialized parts - linear rail block or balls - decent linear rail device can be made. Because ofby janpenguin - Delta Machines
I bought six vertex frames. The major problem I had to deal with was that 2020 Aluminium extrusion I bought locally has 0.25 mm bigger size. Yesterday I cleaned up the frame parts and enlarged holes. It took about three hours to ream the six parts. One top vertex frame I made a crack on this one. One base vertex frame Less than 0.1 mm clearance between extrusion and base vertex frameby janpenguin - Delta Machines
I guess 1515 aluminum extrusion is rather hard to manufacture. Two issues I've found so far when using 2020 aluminum extrusion: Six vertex frames replacement or modification of the square hole. Forty five pairs of M3x8 screw and M3 nut need to be replaced by M4 screws and nuts. I spent three hours yesterday to make 20 mm square hole on a top vertex frame out of curiosity.

Hi, I have a set of 2020 aluminum extrusion and printed parts for Kossel Mini that uses 1515 one. I need three of each part that mounts the extrusions. Give me a quote including shipping fee. Kossel frame 2020 KOSSEL 2020 motor frame Regards, Hugheby janpenguin - Job Shop: I need stuff made!
Hi, I decided to build Kossel Mini from scratch as my first Reprap 3D Printer. Misumi HFS3-1515 has 3.4 mm of slot size where the wheels of motor mounting plate seats. The 2020 aluminum extrusion I can buy from a local manufacturer has wider slot size, which is 5.3 mm. The company provides outstanding price less than $10 for a set: 600 mm x3, 240 mm x 9. Suppose using bigger extrusion doeby janpenguin - Delta Machines
QuoteThat's exactly what I used but I bought from AliExpress I think the shopping mall probably sell electronics for Reprap 3D Printers at lowest price on the net. They offer even free shipping for thirty some dollars of RAMPS 1.4 Kit which is sold in other places at least double the price. But overall processing and delivery time is 30 to 43 days according to their delivery plan. Cheap internby janpenguin - Delta Machines
Can I use it as effective engineering / design tool to build real stuff? Long story to short, I've been studying Geodesic dome technology of Buckminster Fuller for two years to build dome structures including house. It is major part of my Open Source House project. First model, few hours 2nd model , two days 3rd model - 1st half dome, few days 4th model - 2nd dome, a week From this oby janpenguin - General
I use a hand grinder with metal cutting blade for cutting steel or aluminum plate less than 20 cm. It can cut up to 15 mm thickness. The downside is it requires some time to smooth, level the edges after cutting. A machine shop can cut a piece like the image within few minutes, charges few dollars. Making a mini grinder table is an option too. I use it when I need to make square plate a lot.by janpenguin - General
