THK are one of the high end high quality Ballscrews if you are looking at THK then NSK SKF and Bosch there are many other Ballscrew manufacturer's that make quality Ballscrews to choose from, TBI is another that is less cost and good quality worth a look at

Thank you very much for the info mactec I appreciate it.

@DavidA, where did you source your HDPE from and did it come pre-cut in that shape?

Adam,

@DavidA, where did you source your HDPE from and did it come pre-cut in that shape?

Most plastic distributors should have HDPE. McMaster-Carr carries them as well.
Up to 4" thick. They come in sheets, just like plywood. You machine the shape you want.

im still thinking to use hdpe or acrylic for my spoilboard

im still thinking to use hdpe or acrylic for my spoilboard

I don't have much experience with acrylic but would
think that it wouldn't be too suited for spoil board usage.

It's stiff and brittle, would probably crack when you drive
a screw into it and would melt with a duller bit when you
cut through a material you have on it.

I do have quite a bit of experience with HDPE and think that it
is pretty close to being the perfect material for a spoil board.

It rarely melts on even a dull bit as it is fairly easy to cut (68D),
holds screws very well, is extremely resilient (try to rip a milk jug),
holds its shape even over time (negligible cold creep), doesn't
swell or shrink with moisture, is impervious to just about any
chemical including oils, coolant and water and doesn't create
any fuzzies or dust as a wooden spoil board will.

I think the reason that it is not used more often is because
most metal guys don't know much about it and the fact that
it costs about 6-7 times more than a sheet of MDF.

Quick question:

UCCNC seems to run Mach 2/3 Arc.txt files just fine.

Is that the post processor mode to use or are there more optimized post processors for UCCNC?

Thank you

If it works and does what you need no need to change it
It should run any Mach3 programs just the same G-Code is a standard so if it is formatted correctly it will run on most controls,

Unless you want it to do something different, a UCCNC post would be almost exactly the same.

Thank you Mactec and Ger,

Yes, it runs fine with the Mac2/3 code.

Brygga desktop is getting close to test cuts.

First, the machine has been modified so that
the ball screws are fixed only at one end and
the other end is floating.

For Y/A, one clamp side has been modified
to have a rubber bushing for the floating end:
Attachment 419282

For X axis, one of the Y/A carriages had to be
taken out. For that, I used a car jack to unload
the weight of the gantry:
Attachment 419284

Carriage slid out easily:
Attachment 419286

[davida1234]

A seat for the rubber bushing was machined into the carriage:
Attachment 419290

I don't know of any additional improvements but
with one ball screw end floating, the machine
seems to run a bit smoother and quieter.

All these modifications have been incorporated
into the master file for future cuts.

BB ply spoil board installed:

Big front braces installed:

[davida1234]

There will be two clear screens on the machine.

They are not mandatory for function but improve
the dust collection and coolant retention.
Attachment 419302

They simply slide in and out with the grooves of
the plastic trim around the machine:
Attachment 419304

Attachment 419306

The back screen can be left in place as you will
never get there. The front one will be taken out
for loading/unloading or just not be used if no need.

The back screen placed in:

Dust collection installed.

= = = = WANTED = = = =

I will run test cuts for wood, plastics and aluminum.

However, so far, I've cut mainly plastics and aluminum.
I have Aspire but never did any 2.5D or 3D carving and
have no knowledge whatsoever about it.

If there is somebody with a 3D carving file and wants
to see how the machine performs with 3D carving, I will
gladly try to run it as I am curious myself. The file should
have all tool paths and tool types listed so I can get
those bits and set up the machine accordingly.

Thank you.

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

Huanyang Mactec54

PD174= ??? ( To Be Set to the VFD Drives Max Rated Output Amps )

Hi Mactec,

I setup the VFD as called out above. Everything
seems to work fine but I have two questions:

PD174=??? Where do I find the max. Amps? It is not on the VFD.

When I run the spindle, it goes directly to 400 (24,000 rpm).
The up/down arrows run it down very slowly.

Is it possible to start the spindle with a lower speed like 16k or 18k
and adjust up/down from there?

When I set up my Hitachi I only needed to change 4 or 5 perimeters and they were all listed in the documentation (two manuals) . Not hard at all to figure out, the rest were left as default.

[davida1234]

Thank you for the input, wmgeorge.

Unfortunately, I have a HuanYang VFD, not a Hitachi and
the documentation on that is quite vague and I don't know
much about VFD setups to start with. So I thought, I ask.

Does yours start up at full speed? I prefer that the spindle
starts at around 16-18k and I can go up or down from there.

I also would like to know if there is a way to adjust the speed
faster than scrolling from the 1/100th digit. Maybe a pot might
be a better way to do it.

[ger21]

PD174=??? Where do I find the max. Amps? It is not on the VFD.

Might be in the manual. I think it's either 10 or 11.

You should be able to set the frequency before you start it. I don't recall if it remembers the previous setting or not?

There's a plugin for UCCNC that works well, if you want to control it from the software.
