hello
i upgrade Bridgeport mills to mach4 with an Ethernet smooth stepper i am adding vfd to my setup and am thinking about rigid tapping. i am adding an encoder to my spindle. the questions i have are do you set the ramping or delay to 0 secs or what would be a good place to start. i know i can be done with a soft tapping setup. has anybody done this and do you have any pointers.
thank you

I would suggest checking on the warp9 forum, but I suspect that synchronised motion (spindle + motion) is probably not functioning on the ESS within Mach4.
I am not 100% certain, but it is worth a question on the warp9 forum before being disappointed / getting stressed trying to get it to work correctly.

unfortunately that is one of those functions that must be carried out directly within the motion controller and is 100% motion controller (and therefore plugin) dependant

A zero delay would throw your VFD into fault without a braking resistor. The motor will actually send a current back to the VFD. You should also look into adding a braking resistor to your VFD if you haven't done so already.

thank you for your replies I have posted at warp nine. Royce do you have a braking resistor on your vfd and did you always have it or did you add it later. thank you

I added maybe a month after my retrofit. It was taking 5~ seconds or so for the spindle to fully stop, now i'm at less than half a second if not shorter. Cheap chinese one off fleebay, forget the exact size.
