I need help, I have HY VFD and cant get it to work reliable and control the motor properly with Mach3, I am using the RS485 connector
If I just switch to a TECO or other VFD will it correct the...

Thanks for sharing, how much rapid speeds can you get with that configuration?

I have been working for several months trying to get faster Z Axis movement out of a knee mill conversion, I am driving the knee.
I am using a Nema 42 stepper motor, I would like to get 15 - 20...

No you cannot run 24v motor with that VFD you need a 24V power supply

Thanks for the introduction

Hello Everyone

I am converting a JET Knee Mill, I converted the knee but found it to slow for drilling and tapping.

My current question:

Does anyone have a knee mill conversion with a quick disconnect quill X Axis
I can't afford the Elrod design which is awesome,

Thanks
Happy New Year

Hello to All,

Does anyone have plans for a Bridgeport style Knee Mill Quill conversion ?

I am having a similar problem, have you resolved the issues with the solid state relay and the coolant?

Smoothstepper Issues:

On the USS setup does anyone have noise filter numbers to prevent error codes from occurring

Thanks for the help,

Let me try again, the system isn't Modbus, it's RS485 that operates similar to Step / Dir,

The problem is trying to get the Pulley Ratio setup

This is what I have, the...

Thanks again for the support,

Let me try to explain the system better, when say the arrow keys I mean the Mach3 up and down keys located below the spindle button on the Mach3 screens,
When I...

Thanks for the help

I am still a little confused, I don't really understand how frequencies work,

The gap I see in my numbers is very close to 2.44 at low, mid, and high range

When I set...

Yes I can adjust the arrow keys and vary the speed
So I enter 2.441 in the spindle pulley ratio?

The RPM on the name plate is 1720

The operation speed of the mill is max 4200

Thanks the motor mill is controlled through a hand crank from 500 - 4200 rpm when engaged in Hi gear.

What I have right now is the spindle goes all the way to 4600 RPM (read with tach) and mach3...

Any advice on how to setup a spindle pulley?

Mactec54 Thanks

What should I start the steps / rev in the spindle tab in Mach3 under motor tuning ?

Thanks

I am trying to understand the correct parameters to use for my JET knee mill,

The VFD is working the speeds are way off with Mach3 at 500 rpm and the spindle runs at 1500 rpm.

I think its the...

Well I have had some success getting my spindle working better with Mach3

The actual RPM on the mill is 3 X more them the RPM in Mach3, I assume this is a parameter setting in the VFD

Does any...

Need Help,

Thanks for the response,
What I have is a Huanyang VFD that controls the spindle manually now.

I am not sure the VFD has PWM inputs but I will check.
