Overall quality is great! It's really good for the price! THIS ITEM IS HIGHLY SUGGESTED! As described by other buyers the assembly guide (pdf on the provided SD card) is almost totally "pictures" with some minor errors (refers to wrong screw size in a couple places) but anyway completely easy to understand.
Front LCD panel slightly offset, required some drilling to fit on the display knob. Rods where cut to size and glued, all the exact ame lenght (good!). Provided firmware is outdated (some commands ignored), just download a newer version and replace all setting by copying them from the provided "configuration.h" (rod length, offsets, step/mm...).
Glass build plate is not really flat on the sanded side, resolved by flipping it over and printing on the shiny side (with masking tape). Mount the aluminium extrusion to the plastics ON A FLAT SURFACE to keep all "squared"! Calibration is really important, do it with patience! Rose Kevin is very nice dealer!
I ordered this late Thursday night and it arrived at my doorstep on Tuesday morning via DHL. The Printer was very well packaged, no damage to anything.
The delta had great looking parts and most of them are high quality, I was able to get the printer together as it was not very difficult. This is great for learning 3D printing as I've learned so much just from the assembling procedure.
I have not had a single problem with the printer to date, I have been using this printer for more than 5 months now, and I cannot really complain much.
It’s a good product with GREAT customer service. 100% recommendation.
