This printer is very capable straight out of the box. I’m still learning something everytime I run it. It seems to be the benchmark standard for upgrades. There is a large aftermarket for maintaining and upgrading this platform in particular. There is a wealth of knowledge on YouTube for advise to set it up and use it well. Produces good prints without the need to re-invent the wheel. The learning curve is as steep or gradual as you like.I wish it had a standard USB jack or Wi-Fi , the micro-SD is a bit delicate and requires care to use regularly. Still learning how to adjust and tune this printer one piece at a time. Clean-clean-clean. I clean the build plate with a polyamide razor scraper and a spray bottle of isopropyl between each print, and glue is seldom necessary if the first pass has a large enough patch. There is 2020 slot cover strip on a roll from AMZN to fill all the openings in the extrusions to keep everything tidy, or print your own from Thingiverse.Leveling the bed is so simple that a probe is not required. With the Z travel limit switch set correctly, leaving zero gap with no pressure on the plate. Move Z+ 0.2mm and use a personal check 0.1mm thickness the gap the nozzle to the plate and you’re in the ballpark for sure. Check level everytime you move the machine and if adhesion suffers and a probe isn’t needed at all.The spider 3.0 hot end and a metal extruder has me running at 999% print speed with good results on PLA. A filament guide that keeps the crumbs and dust down near the Z-feed screw. I printed the usual Thingiverse favorites to test and adjust the printer before re-tightening hardware and adjusting it for greater speed and precision.Cheers and have fun!
