David A's New 2x3 Bench Top CNC

[davida1234]

Thanks Mactec54, I already had them so I just put them back on.

[davida1234]

Angular bearings arrived.
Assembling everything back on.

With the revised retainer design, the rotating
ball nut Version 2 runs definitely smoother.

At 450 ipm:


Next will be connecting the VFD and the
spindle and finally start some test cuts.....

Looks good

Installing Y/A drives.

Revised layout adds brackets to shorten
the free span of the ball screw. Provides
fixed screw ends in all directions:


Bottom part slips into 8020 channel:


Top part gets bolted down:


Finished installation:

How far from the current end clamps are they going to be?

[davida1234]

.
About 6" front and 5" back.

That's the space on the screw the ball nuts do not encroach
on when the machine is at the front and back cutting envelope.

Ahh I see it now, so you're not using the full space of the router bed. Did you make it bigger for the coolant? Just curious why you aren't using all the available travel. Are you limiting the x travel as well? Sorry for all the questions I'm sure once it's done and running it will clear it up.

[davida1234]

Dan,

The bed is 2x3. Rails are always longer than the bed because of carriage/truck lengths and any other peripherelia you might have. Plus, I wanted to have clearance for my dust shoe and some space for the coolant to collect.

Finishing up the mechanical portion of the machine.

Now to VFD.........

I showed an image of HY electrical
connections I found online and the
discussion about it somehow got lost.

I cleaned it up a bit. Is this correct?

[davida1234]

Also, the VFD is turned on together
with the PS through a 30A relay.

Is that OK as well or does it need
its own on/off switch?

Thank you.

[ger21]

Yes, wiring is correct.

[davida1234]

Thank you Gerry.

Thank you.

The VFD and the Power supply need a correct sized Breaker that can be used as a switch as well, ( note not all Breakers can be used as a switch )

The normal for U V W for it to turn the correct rotation is

Pin1=U

Pin2=V

Pin3=W

Ground Pin=4 (Check Pin 4 in your spindle to make sure it has continuity to the Spindle Body ) if it does not this has to be corrected and connected in side the top cap

This type of Breaker is Ideal, there are other manufactures that have quality Breakers

[davida1234]

Great, thank you Mactec54.

I had published images of the terminals of
VFD and Mactec54 had mentioned that it
looks like the VFD is an older model HY.

I can't find the original images now but they
are towards the middle of page 18.

I would appreciate if Mactec54 or somebody
else has the settings for this model HY.

Here are lower resolution images of those:

You will need to cover the white wire if that is being used as a Hot, if not you should not have a Neutral wire in the mix for 240v single Phase supply

When you Power it up and look at the Parameters what are the first 2 letters being used PD is the norm for HY VFD but it could be something else if your VFD is a copy

What Spindle do you have

Volts=220
Amp=
Hz=
RPM=
Poles=2

That wire is not connected to anything. Removed it.

Here is what shows up in sequence when powered up:

Ok to find what your Parameters are press the Stop/Reset after it has finished powering up, then press the program Key and then enter and you will see what the Parameters letters are the Real HY start with PD for this model VFD

[davida1234]

It is PD:

It is PD:

Ok that's good it is a HY here are the Parameter's for you, you now know how to set them also you just use the arrow keys to get to the Parameter number, this should get you going
