I bought the 3018 Prover and the bed add on to make it 3040 Prover then upgraded to 300w spindle and aluminum carriage. I have to say everything was better than I expected and cuts great. I would give the entire machine and transaction 10 stars if I could.

Aluminum Spindle holder

Haven’t had a chance to use it yet waiting on bits. Very good setup includes limit switches too. Easy instructions on changing it over. Larger spindle motor fits great and snug without any play.

Clear instructions, easy install. Aluminum Spindle Holder Upgrade.

Nothing to complain about. This spindle holder is very sturdy, it put my 3018 Prover at another level. By itself I rate it at Five Stars, however, there is no adapter for mount my LASER. Hence the Four Star rating. Genmitsu Aluminum Spindle Holder for 3018-PROVer Genmitsu Aluminum Spindle Holder for 3018-PROVer Review

More power...

This spindle motor is far more powerful than the original little GS775, 24 volt spindle motor. This spindle motor uses a variable 0-48 volt power supply - twice the voltage, twice the RPM. It's well worth the USD $99.99. To effectively use this more powerful spindle motor, you will also need the Genmitsu Aluminum Spindle Holder for 3018PROVer, costing an additional USD $99.99. It takes about a half hour to swap out the old, for the new... It's well worth the extra cost. This machine will make a great printed circuit board fabricating machine!
