Dreaming of your first 3D printer Number 4

Low cost 3D printer?  Part 4

 

Now the first thing I should let you know is that 3D printing is probably not as fast as you Imagine if you want good prints with a low cost printer. I even see bad prints coming from very expensive printers and a lot of it has to do purely with physics, if your driving your car at 100mph and you could put it into reverse and go backwards instantly something still has to go forward right? Your printer chassis is probably shaking itself apart slowly with every jerk back and forward and from side to side. I saw some of the factory settings on this printer and although it looks so fast when you first see it running, they are not going to get you good prints, If you love sanding and filling for hours then don't change the settings.

 

There are some really good open source free software programs out there and the ones I use are:

CURA 2.3.1 It has a huge amount of printer settings that help you learn.
Slic3r Ver 1.2.9 slic3r needs another program to print, but you can export your prints to an sd card and print from that.
Pronterface I use Pronterface to adjust the printer and it allows you to extrude filament which helps between different filaments. You can also adjust the nozzle height too.
Some have bugs but with a little searching you can find the answers for almost any problems online.

 

My Settings might or might not be useful to you so YMMV My cura settings for your first print can be like these.

 

My Prusa i3 MK2 Settings

 

My printer settings

 

My printer settings

 

I have included a copy of my G-Code settings here. They work good for me but the code is still a work in progress for me until I get it perfect, so feel free to use it at your own risk of course just keep your finger on the off switch the first time you use it.

I still have to put my printer settings into the printer firmware so I will cover doing this in the next blog but for now we can just enter the numbers ourselves, here's how.
Press the button and go to Control/Motion.
Set the numbers as follows:
Accel: 600
Vxy-jerk: 5
Vmax X: 350
Vmax Y: 350
Vmax E: 25
Vmin: 0
VTrav min:0
Amax X: 500
Amax Y: 500
Amax Z: 100
Amax E: 10000
A-retract: 3000
Esteps: 0098.2

You can tweak it faster if you want, try the Accel settings and find your printers sweet spot, where your prints look reasonably good with only a few lines here and there. I hate sanding so I make do with a slow and quiet print rather than everything shaking off the table and a peice of garbage on the printer when it finishes. If you feel like 3D printing is your vocation in life, and you really want to get into it then you probably want to invest in a more expensive printer, one that prints faster and with better results, is more robust all around and comes with a self leveling hot bed, dual nozzles etc

 

Next printer for me to build from a kit will be the latest Prusa i3 MK2 with self leveling, they are so backlogged with orders it might take a while to arrive so hang in there and check back often.

 

Some prints from this kit and the credits well deserved to the many guys and girls that give their work freely for you to download and print.

In the next blog I will be looking at some modificatios that could possibly make your life a little easier when you print, and some possible machine flaws that might cause you problems down the road.

See you next time for machine mods.
