Marius, it is normal for us to slide the pinion away from the motor a bit, so that it is aligned with the rack. (The motor shaft will not go all the way to the end).

Remember you will still have plastic washers between the motor plate and the gantry end - that makes it a little worse.

My pride and joy
 

The spring has come and temperature is rising. What can we do ?
WARM UP THE ENGINES !!! :D

Congratulations....very nice bike!!!

Correct nice bike AND it's a Suzuki..keep the rubber on the road.

Please keep just the rubber and knee sliders on contact with the road...all other things are bad :D

Delivery from China
 

Today I received the oreder from China. Good quality and fast delivery.
Now I can start to build the Z axis. Here are some pictures.

hmm ball screw for Z - interesting - what were the costs involved?

Super price: all stuff was 88 $ :). Transport extra 34 $. The good part is if you don't find what you need on listed ebay items just ask and the seller put the new item on ebay. Top seller. There you can find spindles with VFD, all linear systems, etc.
Give a try.

Serious, did you paid that for the ball screw and linear bearings?

who's that seller - ?

Yes this is for real ! The seler is:
http://stores.ebay.com/linearmotionbearings
And this is my shoping:
Item number: 250387267049
At the begining I was afraid to place a big order but next time I'll go for more items. And the seller works only with PayPal and that give me more confidence.

Control Box
 

It's time to post some new pictures... I loose a lot of time finding shielded cable, ordering chain cable, etc but finaly I start to build the control box :).

Ah, Marius is back! :)

I see you have the high power electrics (with capacitors) flat across the bottom of the box. Just a practical hint; the bottom of the box has a habit of collecting the fine bits of copper that you cut off when installing the stuff higher up in the box. You need to be extra careful with cleanliness, or be willing to smell smoke. :rolleyes:

It's Moving !!!
 

Finally!!!
The beast is moving!!! But…
1. two wire connectors are not match each other (the lady from the shop didn’t know much about what she is selling :mad:) so I couldn’t check the motors in the same time.
2. on X axis one motor is going in a direction and the other in opposite side.
But with all these inconvenient I can say most of the kitchen project is done.
I try to start the scorpion job but I quit because of the engine setup. The only movement I get from the jog with one motors detached from the rail :o.
There are some picture of the control box.

Great news!!!

To reverse the direction of a motor, swop the yellow and red wire at the Gecko.

Thank you again for the answer.
One more question : when you say , it means that I have to move the red wire in the place of the yellow wire and vice versa ?

That is correct Marius. In other words; you reverse one coil of the motor.

But, at this screen today, it does not look "red" anymore! These are the two wires to change around:

Yes I know the problem with colors inside my cable... I'm a little left handed with electricity but building an MM I've learned a lot. Tomorow I'll go to my shop to fix that and many other remains behind. Thanks’ again :).

I'm left handed at everything:D

As long people like Gerald and Richard and many others on this forum are around me I'm not afraid of new things. In Romania CNC machines represents something new but here most of us are quick learners. So even if you have two left hands, the brains can become the right hand. At the end we are in advantage, we are have more than two hands :cool:.

It's Moving For Real!!!
 

Yes, yes, yes ! It’s moving… :D Now I should finish the details and of course the Z axis. Gerald I change the wires but one of the engine start to make strange noises so I put back the wires and check again the MACH 3 settings and finally it works. The mistake was when I didn’t setup the A motor. Like many others looking to hear the beautiful music coming from the motors I skip the reading part…:o
But for the moment that noise give a huge boost.
Here’s the link with a small movie taken with mobile camera: http://www.youtube.com/watch?v=7sf88-nfyl4.
Thank you again Gerald !

Felicitări! It is a beautiful feeling isn't it? :)

Finally after 6 weeks...
 

Finally the z axis is starting to get shape. After 6 weeks !!! Here are some pics.

Wow, nice piece of equipment there. How much price difference between the normal Z-slide and this linear bearing type ?

Price for Z
 

Thanks ! As you presume from the first beginning I was looking to buy something more sophisticated and the first stop was at SKF. They ask for around 2000 EURO. One month ago ISEL was the next and they ask for 1400 EURO. Than I quit searching.
Aluminum – 70 EURO
Bearings and Ball screw – 88 USD
Those 2 bars – 15 EURO
Coupling – 20 EURO
Motor – 50 EURO
Cutting, drilling, etc – 130 EURO
So at the final was around 330 EURO.
The hard part was to find aluminum (thickness 25mm) because everybody is selling large sheet 2x1 meters. I lost at least 2 weeks…
But finally is almost ready and when I said almost because the guys from metal shop forgot to do something but this part is easy to do by my self.

Marius, I have two concerns with that slide . . .
- the stiffness after mounting the router
- keeping the screw clean.
Please keep us informed how it works out.

Marius you need to have a bellow like I built one here http://www.cnczone.com/forums/showpo...&postcount=214

Stiffness
 

Gerald yesterday I observe that those guys who built the Z axis forgot to put screws at the end of those bars. I'll do that today... And I told them several times to do that because everything should be sturdy :mad:.

Motor on Z axis Bipolar Paralel and is moving
 

Hello everybody ! Another small step with Z. I chose to wire the motor Bipolar parallel and is moving quite good. After 4 minutes on jog the motor is slightly warm and the Ghecko is cold. There are something to fix: the resistor is for the moment 60 k.
I'm curios to see is the motor is strong enough to handle everything... For the moment if I try to stop the ballscrew with my hand is not possible. The Romanian supplier buy these motor from http://www.motioncontrolproducts.co....?products_id=6.
All Is good for the moment (I hope...) but I don't know much about setting the motor with Mach3 (steps, velocity, acceleration, etc.).
Any suggestions ?
Thanks,
Marius

We need the "pitch" of the screw for setting up Mach3. How far does the screw move if the motor makes one full revolution? (maybe about 5mm?)
