3D Printers / Re: Cheap 3d printer review

I've been experimenting with settings to get to know the machine. Printing (Hobbykling "Premium" PLA) down at 180C definitely gives better results, and the raft serves no useful function so I've switched it off. I found the "retract" setting that pulls the fibre back from the extruder between prints (like when crossing gaps) which has completely eliminated stringing and surface pimples.

I also Just discovered by experiment that the "accurate" feature is the outline, not the planes parallel to the bed. I designed a part that looks a bit like a saddle clamp, and printing it sitting flat on the bed gave results that were OK, but not brilliant. But printing it sitting on its edge with the groove vertical and the screw holes parallel to the bed makes a much cleaner, more accurate part. This is counter-intuitive and a useful thing to know.

Finally I've discovered that it's better to create the part geometry (STL file) two or three times real size and then shrink it down in the g-code generator (pruslicer). This seems to give much better surface detail - possibly something to do with the way SolidWorks generates the STL files.

Every day is a school day (unless you're in Tier 4)

Quote from: pheasant_plucker on December 28, 2020, 14:03:08 pmYou have discovered the real purpose for 3D printers which is to spend more time printing upgrade parts than anything else.
I've just upgraded my old Hictop (275x220x210) printer with a new frame (300x300x350) and 32bit controller with colour touch screen and now I need to spend the best part of 24hrs printing custom parts for it.

Just like everyone I know who has bought a lathe!  The first year is spent making all the bits and pieces to do 101 other things with it!!  Like the rest of you I have made a few additions to my 3D printer (Ender 3 Pro) but only ones I could print!

Bloody right, ::)  a friend of mine now has 3, all bought in the last year, I have been turning aluminium bits for them and every couple of weeks I go around his place he shows me his printed 'upgrades' and new motors,,

In that case, my memory is faulty - I obviously never mentioned the Redheads to you!
