Yuri,

That gantry video looks great. Cant wait to see those drivers ans steppers running! :)

Did you say you had 2 left hands? :D

Waiting
 

Waiting :rolleyes:

Looking good Yuri.:)

Waiting for your Xmas presents to arrive? :D

Slowly and always
 

Module 1.5

Look at the arrow, not the blue :D

Good to see you again Yuri - I thought you were having a beach holiday down at Costa Verde or some place like that. :D

No...

My father is about to make a heart surgery (intervention in heart)...

Sorry to hear that Yuri - we will be thinking of your family in the next few days.

Yuri,

Hope your Father's surgery goes well.

Yuri,
Best wishes for you and your father.

Gerald, Nils, Heath and all other MM builders.

Thank you for your consideration.

Thank you for this Project, which helps control my demons.

We are praying for your father and your family. ...

You have done well on your project, but family comes first! We will be here when you return.

This post was taking my sleep.

I cut straight, parallel and beautiful?

Gerald, I have two left hands.

After thinking a bit, I have found the solution to cut a plate.

Fixed the plate to a angler. A angle table and fixed the cut. I think it was good.

Maybe someone has a simpler solution.

Z-Slide
 

OK the cut was perfect.

Now I am with this question:

The rail has 100mm. The Z-Plate has 87mm.

But the rails do not come on board.

Is still wide.

What's the solution ?

Cut the plate or increase the distance of the holes more than 132mm ?

Yuri,
Your small tabs on the spider are not bent at 90 deg? What is the reason to having your holes in the Z plate offset? Or am I seeing things?

Because the company that made the bend could not do.

I am still thinking how am I going to do this.

I do not understand this part. " What is the reason to having your holes in the Z plate offset? "

Yuri,

I read somewhere on the forum that some people had cut the tab off and welded it back on in the right position.

It looks like that is the way mine had been done.

Yuri,

I see what Heath is talking about. If you look at the pic of your z plate it looks like the holes are offset to one side (not centered on the plate).

Yuri, 2 left hands but smart thinking!

Why do you already have the 6 rollers mounted before finishing the width of the slide? Did I give a 132mm dimension by mistake somewhere?

Also see this post. Measure the rollers against the slide as in that photo, then you can calculate the final width. (11mm different)

Heath and Greg M,

Now I understand the 11mm.

The correct value is then 143mm.

Correct ?

The drawin gives the 132mm inside brackets as (132), which means to check it first. Also it says "approx TO SUIT SLIDE & V-ROLLERS" which also means to check it against the slide and rollers. (Americans work with 4" plate that is wider than 100mm.)

You will have to make a new slide plate because all those holes must be center on the plate (to prevent problems with the pinion gear & rack and the gas spring). When you make the new plate, you can make it to the right width to fit the rollers.

is that US$35 per piece or for the whole set? i assume it's 14 rollers total?

Per piece.

I am in Brazil and several charges.

US$ / R$ was different today.

is that $35 per unit?

01 V-Roller - US$ 35.00

I would like to inform you that:

Yesterday, in an initial test, which reached a speed of: 1.100 mm/s.
Acceleretion: 2.000mm/s2

Step loss of 1.200mm/s (72.000mm/min or 2.834 ipm)

Unit: Smile Unipolar
EMC2

Direct Connection (without reduction, for now, right JR :))

The construction continues.

Thanks Gerald for the great project :cool:.

Video ; video ; video ; video ; video ; video ; video ! :D

:D
Gerald, wait a little longer.

Present it now will make me ashamed.

The best speed in continuous use is 600mm/s (36.000mm/min) that I believe should be the default for Direct Drive (no reduction).

Not bad for big motors.

BUT, consider that the tests are empty.

Great Job Yuri!

Way to go Yuri...looks like you are spending more time on MechMate than on your motorbike at present......must be the addiction..:D

Forbes
 

I just received a call from Forbes ...

I am revealing a secret to you :cool:

Yuri, you look just like me! :D

Z axis
 

Kobus,
This is really an addiction.
I propose an option for the "Z". :eek:
Gerald perhaps to include to BBBs. :cool:
Pictures of this change, soon. :D

Gerald,
Note that the fixed rack on the rail. Seems to work. :)

Hi Kobus,

This picture is for BBBs :D

More pics
 

I like the handlebar picture! ... Congrats on a fantastic pen plotter!! :D

Happy Birthday Father
 

The feeling is of joy and sadness :o

I did everything to cut this date: January 24. Anniversary of my father.
