View Full Version : FOR SALE: CNC3040 with 750watt spindle

I'm looking to sell my CNC3040. It's had some use but it works well.

I replaced the standard 200watt spindle with a DIY spindle based on an outrunner motor. I have built a 750watt PSU by modifying a Corsair PSU (now had pot inside to adjust output voltage). There is also a speed controller attached to the side of the gantry. The motor is high torque and low RPM. It works aright for most things and can cut light aluminium better than the original spindle.

The controller is a TB6560 based board with a variable voltage PSU. It is set to 25Volts at the moment which is perfectly safe, though I might be tempted to push it a little higher for more speed.

Here are some photos.

I'll also include the above plus a 4 flute coated 6mm extra long milling bit, 3 ER11 collets with a set of ER11 chucks to fit most bits.

If you want higher RPM from the spindle (e.g. for small dia. engraving bits) you will probably want to make another spindle, but the PSU and speed controller can be kept. Basically you just need to get an outrunner motor with higher RPV/volt and replace the shaft with a ER11 collect shaft. This will cost you about 30 total.

These machines with a standard spindle cost about 650 delivered to the UK. I'm asking for 350 + 15 shipping.

I guess it's not me then. That's a shame, I was quite looking forward to using it.

I wouldn't be surprised if it was Irving... He just pipped me to the post a few times and has a great nose for a bargain ;-)

Best thing you can do is to make a new post letting people know what you would like to do with a machine & what sort of materials you would like to cut & ask for recommendations that way, might be an idea to give some sort of idea about budget as well.
