I had the pleasure to install an official Peopoly heavy duty Z-axis. I’m going to give you some first impressions. Bear in mind that I very likely got a pre-release and the final version might be more polished.
So, first things first. This is how it looks:
Peopoly went for a weird setup here. They are using bearings on rails. The z-axis is indeed very sturdy. You can lift the whole printer from the arm and it wouldn’t move by 1mm. So it’s definitely an improvement over the standard z-axis but still, it’s not something I would expect to see on a high definition printer.
I would have expected a couple of rails and good quality carriages. With peopoly implementation you have incredibly little margin of error assembling the bearings (at the factory) and the user has to take very good care of those rails. They must be dry and clean.
Installation was very easy. The Z-axis is a drop in replacement, you can even reuse the same screws. The problem here is that the end stop is about 20mm lower than before, so we lose about 2cm in height and be sure to reset the build plate zero (mine was at about 1650 with an easy to level buildplate).
Another hiccup is that the arm is too thick and hits the vat when it reaches the bottom, so you have to remember to not push the vat all the way in.
Okay then… How does it print?
If you already have a good-printing Moai, it doesn’t really change much (if at all). If you are experiencing notable wobbling or you often print very big model, then yeah, this update might help. Of course it’s all down to pricing… which I don’t know.
Like I said… there’s little to no difference from the previous axis (left new, right old).
