G9972Z DRO and Brushless VFD mods

Hi rich.
How is the machine performing now that you have been using it for a few months?
Thanks
Dan
 
Hi Dan,
The lathe over all is performing outstanding. A lot of torque and the large range of speeds operation is a really nice bonus feature. My only minor issue is i occasionally observe some slight rpm fluctuations (not touching the speed selector dial) . The speed selector pot dial switch is quite sensitive to movement.

Dan's website says the motor is spec'd for 60Hz (what we use in the US) but I wonder if the control unit (or any of it's components) might be 50Hz, as used in China?

I don't know squat about electronics, so take that with a pound of salt. I only raise it because a friend bought some fancy industrial sanders for his flooring business and had trouble with every one of them. The US distributor and the manufacturer (in Europe) finally figured out that our 60Hz power frequency wasn't playing nice with their electronic bits designed and tested for 50Hz...

@Road_Clam @The Custom Crafter Hello guys. Any update on having a turnkey kit for the G9972Z? Thanks!

The G9972Z looks near the same as the g4000. In reality many have almost the same design.
If you remove the motor take an image of the mounting and provide measurements + remove the spindle pulley and measure the shaft and key. With that I will comment on the likely hood that it fits. It may require a different length belt.
If I say yes and it does not, return it for a full refund.
Otherwise a new mount and maybe a new pulley needs to be made. We can discuss that as well.
Thanks
Dan
