710W Compact Router 65mm Diameter, 6 Variable Speeds Palm Trimmer Router, with ER11 Collet & 4 Carbon Brushes, Spindle Motor Upgrade for CNC Machines

Works excellent, super quiet.

Surprisingly rigid, low noise, and vibration. Just make sure you tighten the fasteners for the brushes right out of the box; they come very loose and can cause problems.

This router upgrade transformed my 3018 from a nearly useless toy to a highly capable little machine.

Works as it should

This Router replaced the under powered motor that came on my Cncest 6050.It helps reduce static noise that was affecting machine performance and has a lot more power.It is definitely a lot noisier then the spindle that came with the machine.

Had this for a week and it died during a job.

I like this router a lot. I upgraded from the 20K spindle on my 3018 PRO (and got the all-metal carriage upgrade), and despite it having a higher RPM and significantly more power, it's quieter and shakes way less.

This is a nice little router for the price to upgrade from your 70W or 300W default CNC spindle. If you still want to say with the ER11 collet, this is a fine choice.SS Relay use and issues:(UNPLUG power source BEFORE installing this, recommended ONLY for those familiar with electronics)It has a soft/slow start circuit on its initial operation, so you WILL encounter issues if you are using a SolidState Relay to trigger your router power; it will not start on its own. (There are switch step processes to work around this, but it defeats the purpose of a relay in the first place). To fix the relay issue with this router, install a high voltage (ie 600V) 104k (0.1 microfarad) capacitor from the AC load side terminal (the black wire going TO the router) on the relay to the neutral/common/white line returning back to the plug/power source. This will drop the voltage that the router 'feels' that was confusing the circuit. It wont pass any real current, but be sure to cover/tape/wrap the exposed leads and I recommend soldering the capacitor lead to the neutral so it wont come loose. ALWAYS cover exposed leads and terminals.Its a wonderful CNC router upgrade for the price, however I DID go back to my Makita RT0701CR router for my XL6050Pro CNC. I LOVE ER collet designs, but the Makita edged the 710w Genmitsu out in 3 or 4 other areas, so I just went back to the Makita and its proprietary collet.If you are using a 75 or 300 watt default spindle and are looking for the best, least expensive option for an upgrade, this 710w Genmitsu router is a FINE choice.
