Check Factory Wiring Before Assembly
Factory wiring may be incorrect, with motor connectors on the wrong ends, requiring full disassembly to fix. Instructions omit moving side rails forward off the limit switch when installing the cross beam. Software setup gets stuck in a loop of warnings that don't explain the actual problem. The machine seems like it will work well, but only one simple project has been carved so far.
Pros
- + Seems like it will work well
Cons
- − Factory wiring incorrect
- − Motor connectors on wrong ends
- − Full disassembly needed to fix wiring
- − Instructions omit moving side rails off limit switch
- − Software setup stuck in warning loop
