Router has died. Need Advise Please.

[JAZZCNC]

After reading more about VFD and after speaking to the supplier, I have changed my order to a Air cooled spindle and matching power supply that is simple to connect to MACH3. It will have more power than my old router with a lot more control, so at slower speed it will be quieter. It's all I need
I have been reading lots of problems with VFD in setting up and also one which overheated his new spindle to scrap after getting the setting wrong on the VFD and he had a electrician wiring it.
So I'm happy with the decision that I have made. Keeping it simple. Mike.

Sorry to say this but that was a mistake and in the long run I don't think it's any simpler because of limitations in use.
The VFD's are not hard to setup at all and ounce done that's it you never touch them again. For every one that have trouble there are 1000 that don't and even then it's not the VFD to blame but the user's lack of knowledge or care to make sure they have the correct settings. To fry one of these Spindles they would have needed to have it very wrong.!

Air cooled or Water cooled connecting to Mach is the same. Both will need speed control if you want to control speed from within the G-code. Both will need a relay to just control On/Off which your BOB will most likely have. The VFD has one built into it which can be programmed to come on or off with the spindle to control water pump or what ever you desire.

The thing the supplier may not have mentioned is the Duty cycle of the Air cooled spindle. The time can run the spindle before having to turn it off for a rest and cool down.!! . . The Cheap air cooled spindle if run at full speed will possibly need resting for 20-30mins every 2-3hrs and even the expensive Air cooled spindles will need resting 8-10hrs if run at full speed.
The WC spindles don't really have a Duty cycle and they run so cool they can be run at full speed for days without any trouble, mine often gets run for 12hrs none stop without even flinching.

Also because they are Air cooled they will have a fan just like a Router so will be noisy. WC spindles are much quieter and yes you still get same noise from cutter/material but even allowing for that they are much quieter than Air cooled spindles or routers.!!. . . Really Only those who have had Both can fully appreciate how much.!!

If possible I would reverse that decision.!!
