One Finn's long build process

So better late than never? I started building lr3 in March 2023. And “stopped” in August 2023.
I had been thinking and planning about building a CNC for over 10 years. and in February 2023 I even got my own design done. After calculating the price, I threw the idea away. Luckily I found V1e lr2 and after that I found this forum and also that there is also lr3. I had the stupid idea that I could use my old anet 3D printer parts and save a lot of money XD. I made a proof for myself and my wife that it was only 300e and my dream would come true. And so I started. pictures are better than a thousand words.


it was ridiculously cheap for me to make the parts out of aluminum. like an employment relationship. So I decided to make all flat parts from al.


Note that plastic hammer. Important help was given by ten little fingers :wink:



It was not problem free build. But is there any XD For example screws was huge problem to me. I did found out that there is no good place where to buy screws. I did buy them from 4 different places -_-

After I got some sense on my head I decided that I will build it propely or not at all. So not more old printers parts. Expect powersupply.

at this point I got stuck. I had no time or not even place where I could use this. Also my wife had carried all my tools and things to our sauna. she said: this so full you really MUST move those away or… How it could be full ? there was only one lr3, one 3D printer, 6kg filaments, one exploded 3d printer and 4 toolbox XD
I almost gave up and tryed to sell this. Happily no one were intrested. I did squeeze some time and build it fully. I found place and I made wobbly (badlly mistake) table from pinewood table. (I don’t regomend pine under y-rollers!!)






Happily I now have (now and then) working cnc machine for my needs. Help has been given and it has been helpfull, reading tgis forum. ( I’m addictect for this forum :joy:) Thanks all who have helped me and thanks @vicious1 :blush:

that was quite long post, those things were made on 2023 What is the status now? I have some small problems, but I have solutions for those.

What about future?


Updates ofc. Not trying to make better machine, but educate myself.

Congratulations, that’s a great looking machine.
I’m looking forward to seeing more of your projects and the developments as you upgrade/modify your setup.

What a fun looking build, that is by far the most metal in one LR3 for sure!

And more metal parts are coming :sweat_smile: :sweat_smile: I’m trying to redesign motor holders made of different aluminum profiles, trying to keep the parts as light as the originals. Not knowing if I’m ever going to make them…

WHOA!!! NICE!

2mm ABS sheet. Much faster to cut with cnc than print one. :grinning:

Not going to get as light as before but not significant weight raise. Should I try to make this…?

Weight is not really an issue. Looks like a fun project! With a metal mount you can run your steppers red hot.

If youre going to redo the motor mounts and weight is a concern, you don’t need to retain the mount into the YZ plate and its associated M5 screws and nuts, so long as you can replicate the motor position.

I think I will make M5 threads to motor mount. I’m studying mechanical engineering and this is pretty good machine to try my skils. In this I just try can I make some difficult parts to cnc machiniable. I mean you can do z-mount with cnc machine tool as it is but it would be expensive. So I did make some guide lines to new parts. No more much weight, must be cnc machiniable, if its possible make from profile (like L or T). Original plates modificatinons only if really nesessary… and so on. I did make sure I have much to do XD
