I already owned a Prusa i3 MK II and a Raise3D N2 in the past. I didn’t get happy with those machines (always an issue instead of printing) and now I’ve been trying my luck with a Zortrax M300 for about a week.
Before I’ll start with the negative points I want to emphasize how much I love this machine. The frame, the look, the axis-design, the z-material (especially the 2000g spools), the printing quality… almost perfect… almost
Here we go with my issues:
- SD-card-slot should be outside not inside
- sometimes it's not possible to tighten the 3 bed leveling screws (pushing down the plate to fix the top alan screws below the bed helps sometimes, but I always remove the bed and tighten the screws right at the beginning))
- spoolholder on the back is not a good idea imho (but no issue see image)
- z-ultrat and z-abs possible in the near future?
Software (Z Suite v1.10.0, FW 1.1.0)
- print does not separate well from the raft and it is really difficult (almost impossible) to remove small and fragile parts (with z-hips not funny and with z-glass really a pain)
- support on the other hand does not stick enough to the raft. I have a lot of designs and objects that have large areas with support on the base layers. Can't print them because support gets lifted of very often
- with external material (I tried different PLAs and polymaker polymax) the print and the raft get melted together completely... absolutely useless like this. Users should have the option to set the distance between raft and print (as it can be done with IdeaMaker) or play with the flowrate of the first layer above raft (Simplify3D)
- I printed many great shell-objects with the Raise3D N2 but can't do this anymore with the M300 because no support will be printed in "shell-mode". Why?
- z-hips sometimes get burned (fan issue or software I'm not sure)
- if bed is full down (after print) and autocalibration is initiated the z-axis tries to go down a little further (horrible sound and definitely not good for the printers health)
- the slicer "swallows" thin parts sometimes
- there should be a way to add or remove support manually and to tell the program to allow support only from ground or also from the model itself
- the whole z-suite is just not performant enough... definitely not state of the art. Simplify3D can slice an object at least 10 times faster
- large or complex objects bring z-suite even to crash... and believe me I own a damn fast computer ;)
- why is it not possible to heat bed and extruder at the same time? Heatup process takes just too long
Well you guys from Zortrax... don't get frustrated while reading this. I will keep your machine but I really hope those things (most of it software-issues) will change in the future...
Best wishes from Switzerland and keep up the great work
