Rack and pinion have an issue of Backdrive when powered off when used in the Z axis. I have not built my printer yet, but was curious if the belt drive versions also backdrive when the power is off? Asside from cost, is there a reason leadscrews are not commonly used in the Delta printers? Marcby addicted2climbing - Delta Machines
Hey Guys, I am in the process of gathering the parts to build a mini Kossel and before I did, I was curious if I could get an item or two test printed. I would be willing to pay whatever is reasonable to cover the costs of time and material. I need to verify that a design I have will be functonal when printed with a filament based 3D printer. Both parts are about 1.5" sqaure or so.. If anyonby addicted2climbing - Delta Machines

Hey WoodenCaseo1, I saw that as well and it looks like they took the Kossel idea and are marketing it. My design intent is similar to theirs as I want to avoid multi length rods and a non adjutsable arm is what I wanted to do. However the last material I would choose is plexi for that... Seems they got hung up on the clear idea so much so that they kept the arms clear... I have a different mby addicted2climbing - Reprappers
I just ran across the Kossel design and its quite close to the methodology to the design I had in mind. I might order the pre printed parts for it, build it and learn from it. Chances are I'd learn a thing or two I could put to use in whatever I design.. Marcby addicted2climbing - Reprappers
Hello All, Thanks for the great replies. While I have a few items I would want to print that are long, a larger printer also gives a larger area to print many small parts too. I woudl never expect to print the full volume area, but more like a large rectangle but less than an inch thick. If I were to go with a 3mm filament to bump up the speed then I would do that at the sake of layer thickneby addicted2climbing - Reprappers
Hello All, This is my first post and I am about to start the design a printer. I have over 30 years in the precision linear motion indutry and would like to my skills on a project to have some fun with as well as I have a need for a larger format desktop printer and have yet to find one to buy. Are there any 3D printers with x axis in the range of 24"? If not Why? Some dificulty I m overlookby addicted2climbing - Reprappers
