User Reviews

Overall, reviews are mixed. Many users report critical issues: the app often fails to read G-code, struggles with USB/printer connections, lacks Ender 3 family support, and is unstable during use. A smaller subset praise the app as handy and effective on certain devices or for testing DIY printers, suggesting it can be useful when functioning properly but currently suffers from notable reliability and compatibility problems.

Pros

Some users say the app is awesome and works well for them.
A few reviewers describe it as exactly what they were looking for and better than alternatives.
Users report it can be handy for testing or experimenting with DIY printers without a PC.
There are positive mentions of it working on at least some devices (e.g., Motorola), suggesting device compatibility for some users.

Cons

Multiple reviews state the app won't read or validate G-code from various slicers.
Frequent USB/printer connection issues, including messages like 'USB device not found'.
Missing Ender 3 family settings/support (Ender 3 Pro, Ender 3 v2) and related configuration options.
Stability and reliability problems, including axis misbehavior and abrupt stops that require reconnects.

As one other user mentioned it won't read any gcodes I've tried 5 different slicers thinking it could be the way the slicer does it's slicing but neither one would read the app says it's not a valid gcode I wish it worked because it would definitely be a handy app I'm not going to uninstalled it just yet and hope this gets fixed in the next 30 to 60 days I guess if it isn't fixed by then I won't have any other choice but to uninstall it
