RepRap Mendel Prusa 2 – Build log – getting started

Posted by: Raynerd In: 3D Printer RepRap Mendel Prusa 2

After finishing my CNC machine, I`d quite like to have a go at a 3D printer as the concept amazes me. The guys on the IRC channel are really helpful but I am pestering quite a bit as there seems to be quite a few differences with the Prusa2 over the older versions. I do intend to come back in here and add more pictures and comments once it is working and I know it is being done correctly, For now, it is maninly just an update on progress.

I received my parts a few days back, really chuffed with them… cheers ParCan!

M8 threaded rod and 100 nuts and washers, along with a mix of other fasteners came to about £12

Started on the triangular sides:

Next step is to connect the sides together.

So got all the cross members on to link the two sides together and then jigged it out. Now I must admit, I spent about 1 1/2 hours getting it square as it kept twisting!

8mm linear bearings clipped into printed bearing holders

Then mounted the ply bottom table onto the silver steel using the bearings.

At this point I realised I`d mounted the bars on the wrong side of the frame. On the Prusa2 the clips should hold the bars at the top of the threaded rod and not hanging as it is in the photo.

So I`m now running an evening behind as I`ve now flipped the bars around and mounted the motor and timing pulleys… update tomorrow!

Good grief Chris – every time I think about something I’d like to do – you’re there ahead of me! This may be something to do with actually getting on and doing things rather than just reading about them……

This is another of your projects I’ll be following with great interest…. so much less effort than really doing it myself.

Good luck

Haha – thanks Alan. Yes, once I`d got hold of my parts the build has been pretty straight forward so far but best not speak too soon as it isn`t running yet! The Prusa goes together very well but I think in some respects, I`d have prefered to go with a MendalMax instead of the Prusa… but that can always be the next project!!

Take care.

Welcome to Raynerd.co.uk

I`ve always wanted to learn more about engineering and electronics and my list of projects both complete and ongoing has been growing over the past few years. I like to document my progress more for my own understanding as much as anything, it helps keep me on track. I hope you can find something of interest to you, my clock building project is my priority but as you can see, I have many other builds I`m working on. Please leave a comment, it is nice to see people are reading!
