DIY 3D printer as an experiment and the start of a 3D printing adventure
The 3D printer is a subject that has interested me for a long time. I thought my own 3D printer was completely out of my reach, until I had my first exposure to an Anycubic Photon resin printer that I got for repair. Once the equipment was up and running I was able to play around with printing. I went nuts 
However, the time to print a part took too long for me, so I became interested in the subject of filament printers. I had a couple of T2040 and v-slot profiles in stock with rollers and gantry plates, so I set about bolting them together. I also had a 'sample' linear guide with carriage from IGUS-this was my Y-axis. I purchased a BigTreeTech SKR1.3 controller with TFT43 display and TMC2208 3.0 UART motor drivers. The stepper motors had been lying in my cupboard for a few years. Now they have come in handy. For the Z-axis I used M8 threaded rods (ordinary, rolled ones from the market). I made all the necessary motor mounts, belt tensioners (and more) from FR4 2mm laminate. I bought an MK8 extruder and a HOTEND E3D v6 and a few small things and after a few days the launch took place. I should add that I had originally thought of an experimental design based on old CD-ROM drives, but I now know that this would have been pointless due to the very slim possibilities. The printer, after a quick calibration of the table, extruder and Z-axis, started working perfectly immediately (perfectly for an amateur design built "on the knee"). Today this machine is in the process of being expanded, on components printed by itself 
but I would like to present what was then created driven by dreams. At the time, as it was a prototype, I didn't think about tidying up the cables - I put everything together on a table and the first prints were created under these conditions.

Bravo for your self-denial in creating your device. What kind of working area did you come up with? Think about replacing the screws with trapezoidal ones. [Read more]
Thanks 🙂 Although the table was 235x235mm the range of movement was limited to 150x200mm. [Read more]
Super! I started with the Anet A8 and only today I see that a printer comparable to the Anet can be assembled in-house, I think with much better results. The pain of my Anet is the levelling of the table.... [Read more]
I do the levelling "on a piece of paper". I do this with the table and nozzle warmed up to operating temperature. Exactly. My guide is also so short :) But I later replaced the guide with linear... [Read more]
I also had a sensor of my own design in my folding machine, now it levels on a paragon (0.05)mm and nothing more is needed. Show me your prints, how do the layers come out at the gw bar? On the z-axis? And... [Read more]
For the price of the Anet you won't build anything that prints like it. The control chip of the colleague in this thread is more expensive than the whole Anet. To the author of the topic: the use of... [Read more]
Oj HandMade I have the impression that the author wrote that this is a prototype version built "on the knee" and there are pictures of that. As for my Aneta I am not concerned with building a cheaper... [Read more]
Of course, I had to calibrate the Z-axis movement. I established an initial reference point and used the controller to raise the Z-axis by a few cm and then measured with a calliper by how much the height... [Read more]
I see it is not that, what nozzle because I think it is big, what height of layer? Did you have any problems with the sliders? I read that they must be quite accurately set because they jam. I took 4 pieces... [Read more]
Very nice, there's nothing like the satisfaction of building a rather complex device with your own hands. Looking at the pictures of some of the components that are made as 3D printing, one can come... [Read more]
Buy the printer...print the printer and return the printer :) [Read more]
A 3D printer is not just about plastics. In the case of Prusa and its clones, one printer makes another. What remains are the electronics and mechanical parts. [Read more]
