Hello Mike,


You have 153mm under gantry.
Also you need some type of sacrificial surface 18mm?

Let's say maximum of 50mm of tool stickout length, and 20 mm safe distance to avoid hitting...

Hello Tim B,


Welcome to this forum.

This one of the best places to get information on diy cnc builds.

Most people post their ideas and design concideration in a ( pre ) build log.

So...

For who needs a few bits.

YES sorry, typo dvm.

Do you have a dmv?

It would help to measure resistance with bus bars of and capacitor disconnected

Then we might get a clue on where the coils are connected.

Haha yes last 2 pictures work for me.

There is no real difference.
effect is the same.


The bus bars i am not sure of until we know where u1 v1 w1 motor wire go.

What is confusing in the...

Hi stonelesscutter,

Have you considered having your design laser cut?

They dont care how many holes you put in your design.

Hi Mark,

I think some of us can.

It is just that i would want to see where the capacitor wires are going. just to be sure.

Basically one moves 1 power lead from one side of the capacitor to...

Hi Nick,


Looking good, keep it up!

Hi waldo,

I spend only €13,- on 5 units... m8 6-36 vdc 2mm sensing distance.

Aliexpress

lj8a3-2-z/bx npn

Just a single meter of wire on the sensor.

Oh yeah.

Hope it serves you well.

Keep us posted.

Grtz Bert.

Hi charlieRam.

I think what everybody is saying: there is no real risk.
Else they would say:
Dont do it, it is going to fail.
People here will tell you if your going in the wrong direction.

Ok so i figured some stuff out.

Made some (very slow) progress and produced the first parts for my diy dust shoe.


I need to get familliar with F360 modelling and manufacture options contour ...

Hey Nick,

I like it that you are making progress.

Keep up the good work.

Hi Paul,

Are you sure about the stiffness you describe above.

As a rule of thump, steel is more rigid by a factor of 3 for a given shape at the same weight.

Box section should be more rigid...

Today i did some rigidity testing.

My findings are Y and Z direction are much stiffer than the X direction.

Because of a design decision to have the x ballscrews near the top of the bed there...

So i finally solved my 0-10 volt to VFD problem.

Some things in the manual are not completely like the vfd in real life.

The terminal vr does not exist.
Missing that one made me search for...

Hi guys finally,

Hi BriceO,

Do you need a better closeup of the counter bore?

The math is sound :-)

I found that my box section 1850x120x80x4 mm was + 2 mm bend in the middle by welding heat.

I had a +/- 1mm error in spirit level. over 1850 mm...

It all add up. so 6mm...

Hi Nickhofen,


I can post the before.
I can make a few pictures of the after later today.

Seal vs ring.
Look at the gap between the seal and ring.

And the opened bearingblock.

Well he said it had something to do with a bulk order from a client and complaints about resistance from double seals and getting things mixed up.

Anyway i am glad i bought from him instead of...
