Any news on this?
Yep got them and they are darn pretty, but sadly I haven't had time to take a look yet, but I definitely will then the Christmas dust settles.
Looking good, where did you order them and how much did they cost?
robotdigg and I must say I am really satisfied with them, they have zero play and runs perfectly smooth.
And how do the sides of your parts look when you study them critically? And compared to before?
Okay, so I pulled the trigger on this upgrade, my sides are horrible due to one of my z screws being... well not straight at all.
What did you set your z-steps at?
Maybe I missed it but where are you sourcing the parts? I am always interested in Bigbox Upgrades
Have been looking forward to a report on this since the end of the summer.
I have the general impression that the best Z axis results come from printers either with small printbeds (eg Ultimaker) or those with an H-configuration (eg Prusa Mk2).
If @JesperJuul isn't here jumping up and down with excitement, maybe means that ultrasmooth and precise ballscrew stepper shafts didn't lead to a radical improvement in the sides of his printed parts, only to a reduction of his bank balance?
Or he hasn't installed them yet
I'm really sorry if you have been waiting on my 2 cents on the ball screws, but the case is (like @eca is pointing out) that I never got to install them.
Short after I received the screws one of my buddys really needed my big box and was willing to give me a good overhead for it, and since I have other printer and he needed a well tuned machine for his business, I gave it up.
At the moment it is not possible to get a new Bigbox so I'm kinda stuck with the project... BUT I just received another screw that is going into my first printer (solidoodle 4) that I'm rebuilding at the moment.
I will update once I get it running.
Your a good friend, not sure I could give mine up
I'm really close to just cut one self on the lasercutter and then try to source the parts myself.
For now I'm concentrating on finishing the solidoodle. I just got the ballscrew in and damn It has stiffened the z-axis a lot, really excited to test it out.
If you do, consider upgrading the frame for IDEX, trying to figure out the best way to do that right now
consider turning the bed through 90 degrees like BCN3D
of course that will mean moving the ballscrews
I must be blind I don't see the balls screws any more, did they stop carrying them? I swear I saw them in the last week or so.
Never mind I am just blind
Turns out Richrap is a ballscrew fan.
Here he talks about his dream printer:
Richard Horne: If that dream 3D printer was not just a one-off for me, but actually designed as a mass-production kit? - then I would use many more solid CNC style parts in the construction - Probably high-speed but small scale ball-screws, high-torque motors and a very solid frame. I would make it Cartesian but with a gantry style configuration so almost any type of surface/object could be printed on. I don't like moving print beds so all three X,Y and Z axis need to move quickly and precisely, with as low noise as possible.
Be careful, I just ordered the ones that were posted here and they are actually bigger than the original ones. I will have to see if I can drill out the holes, if there is enough material there for that. Apparently, the 1204 stands for 12mm ball screw with 4mm pitch. So to have the same size a 0804 would have been a drop in fit with only changes to the steps being necessary.
If you havent aleady made the switch, you should pick a couple bench mark prints formthe before and after. Also I would try and use the same materials so you (and we) can see the effects.
