P3Steel from Poland – A tale of dispair, dismay and woe


Don’t get me wrong, I think that the P3Steel 3D printer is a very good design/derivative of the Prusa i3. However, the version of the frame that I purchased is somewhat lacking in finesse, and the supplier, from whom I obtained it, leaves something to be desired, when it comes to pre-sales and after-sales care.
The frame that I purchased was the Frame Prusa I3 P3Steel v4.0 +RODS, from a supplier based in Poland.

Bearings explained


Whilst research, designing and building a P3Steel version 4 3D printer, I was a bit confused when it came to the various types of bearings required for the threaded rods, lead screws and GT2 belt pulleys: 624zz, 625zz, 605zz, F624zz, 608zz, etc. Fortunately I found this page, Notes on Ball Bearings, which explained the nomenclature. I have reproduced the page below.

Looking at heatbeds for 3D printers, in particular a 200 mm x 300 mm for a P3Steel v.4, although a heatbed of that size would also be suitable for a Wilson II, amongst others. One of the things that needs to be considered are the costs of the various configurations. It should be noted that, when compared to the usual 200 mm x 200 mm heatbed/build plates, there is an additional premium to be paid for the larger 200 mm x 300 mm build area.
