Recommend a controller board

[Turner1]

Hello

New to CNC and looking for a little help. We have a Chinese 3 axis router (Redsail 3040) that we are considering converting to mach4 hobby, and would like to know which controller board you would recommend.

Present controller: DSP 0501
Drives: Moons' SR4H
Spindle: Xinfutai VFD FT-C series with 800w motor.

We would prefer to use a USB connection to the computer rather than the existing parallel cable, and have capability to add a C axis in the future.  Strictly a hobby/learning experience.

Thanks in advance

Richard

The Moons' drivers and Xinfutai VFD both have conventional interfaces and
will work with our SmartBOB products. Documentation is available on line
for these products.

Because your configuration includes a VFD the electrical noise environment
is somewhat harsh. We would recommend the PMDX-424 for this situation
because it offers an electrically isolated USB connection to the host computer.
It also provides more input signals for things like home and limit switches.

In addition to the PMDX-424, you may want a PMDX-407 which will allow
the Mach4 software to control the spindle speed. If all you need is on/off
control for the spindle, you do not need the PMDX-407.
