After more than a year learning and enjoying this fantastic site, I decided to prepare my own space to go on adding construction news.

At this time, I making the garage to put Mechmate and buying materials.(Many chip$)
Can forgive my ignorance during and before the building with my questions.

I prepared, in flickr, one account for place in the world the mechmates photographs. put your place is free and simple.

Good Luck Ros!

Ros wonderful, I have asked http://www.hepcomotion.com/index_es.htm budget and costs € 38 ($ 53,7) each bearing W3, I think I will get in touch with Superior Bearing Company.

Ros, sorry about the photo posting problems. I hope it is right now?

Thanks very much Gerald. The problem was that I accidentally deleted images.

Hi Paquintosh im very impressed with the Superior Bearings Quality, Recommend you this 100%.

Paco, si estás en Madrid, puedes mirar por las zonas industriales a ver si encuentras buenos precios en material.

Ya nos mostrarás imágenes de tus progresos.

Regards.

Mamba parts arrived

Today, the mamba parts arrived.

The Quality is the best, im very happy with the results, Pressicion, service and price.

The spider is perfect aligneed and bended, the laser cut is very clear.

Gerald, The Cutting company is very grateful with the quality of plans. Thanks!!!

Ros,
A couple of things to watch out for, the upper little tab on your spider still has to be bent, you can do this with a hammer and vise. The second is that your Y car estop flange is bent at 90, it should only be 45. This can be easily fixed with a little muscle as well. My bender did that too on the first try. :)
I see you also had your z slide plate laser cut, did you do up the cut file yourself?

Ros, at my day job we sometimes spend €10 000 per month (per order) on laser cut steel. Every time the delivery arrives, I stand and look at it for a few minutes in amazement at what quality is received for the amount of money paid! :)

Ros, that company will have cut the material?
It is important, as will the plans of mechmate.
And the price is right.

¿Qué empresa te ha cortado el material?
Prefiero hablar con ellos porque ya tienen conocimiento de los planos de la MechMate.
Y el precio es razonable.

Sorry for my english

Thanks Heath Im fix this, the Z plate is a dxf file im prepared with the Gerald Help, maybe not is the best steel for the Z plate, is the 50cm plate.

Ok Gerald, The company is big and i think hi know wen a work is fine.

Hi !!! Paquintosh, I can sent you the company from Barcelona to you mail, their only work via telephone but receive the files via mail.

Les puedes preguntar por el trabajo realizado recientemente para Canarias, seguramente tienen los datos en el correo aún, si no, los puedo reenviar, ya que los tengo preparados.

Regards.

Heath, the upper litte tab is bent :) see in this image.

Attachment 5901

And the file for the Z plate in dxf format: Attachment 5918

Ros,
Sorry, the other photo looked like it was unbent. Thanks for the file. :) Good luck.

I have a problem with my spider.

Is 6mm smaller than the Y-Car.

Attachment 7184

I'm thinking in add washers to complete the 6mm but this is one unstable solution

That is not a problem . . . . . . a problem is when the spider does not fit in the Y-car! :)

Fill the space with washers or a plate of the correct thickness.

But the distance between center points is perfect

Attachment 7191

And distance in the Y-Car is OK

Attachment 7192

Dont worry Ros, it is designed that way, we have all added shims or washers to our assemblies. It also gives you the opportunity to adjust the spider to be 100% perpindicular to the table.

Thanks Gerald Alan.

yes, I'll put a plate of 6mm between the spider and the Y-Car.

What can one do if it does not fit? I have assembled the Y car without welding it, and tried fitting the spider in, and it was not going to go in without force. I measured the distance between the inner sides of the y-car, and it is within specified limits, and the outer distance of the spider is also correct. I am scratching my head a bit.

http://www.facebook.com/photo.php?pi...8&id=702675335

The hole through the y-car is 200mm +/- the typical tolerance of a laser cutting company, which is about 0.1mm.

The max. width of the spider is 199mm (see drawing 10 40 432 B).

You can get interference problems if:
- the laser cutting is inaccurate (not very likely)
- you increased the thicknesses of 10 40 432 (spider) and/or 10 30 455 (tower carrier)
- the bending of 10 40 432 (spider) was not accurate.

The solution is to increase the 45 degree bends of the the spider until it fits.

Anton,

I had the same issue, we where 'off' by about 1mm and we simply grinded 1mm of the spider, about 0.5mm on each side.
In our case the problem started because we had plasma cut parts, teh spider was bend perfectly.

Ries

Cool, will try that. Am unfortunately at work in Kenya, so will only be back home mid jan. Keep well. Thanx for the advice.

After a long time out of service, return with more news.

You can see the second page of this Manual

Hi Ros

I saw your youtube video pop up in my google alert for "Mechmate" - the motors move so well done.

My Mechmate is set up roughly the same in terms of drivers and motors. The Leadshine stepper motor drivers can be configured using a special serial cable and software called ProTuner. This process is just like tuning the gecko drivers but with the PC rather than a screw driver. Each motor is done one at a time.

To tune the motors, get the cable and run the software. It then looks for the resonant frequencies that the motor has and smooths that out for you.
Watch the protuner run and you will see that it runs the stepper motor through a range of RPM's to establish it's performance. Note the Protuner is run with the motor unloaded.

After you have finished remember to save the setting to the drive.
You can also use the software to set the the AMPS, microsteps and standstill current if the dip switches are set to allow you to do so.

Hope I have made the two functions of the ProTuner software reasonably clear for you.
Another type of "motor tuning" you might have read about in Mach3 is a further step that is additional to the two other functions I have outlined above.

Keep up the good work.

Regards
Ross

Thank Ross.

Interesting tool google alerts.

Another think.

I'm searching gears for my motors, for gear direct to the MotionKing 34HS9801 shaft.(14mm)
In the search, im see the Chiaravalli here in Spain Gear catalog.

Their have different module1 Gears with the dimensions near the DP20:

Attachment 11038

Im thinking about the distances between A and B.

If the MotionKing shaft is 14mm and the DP20 Gear is 16mm in B, it only give me 2mm when drill the A hole to 14mm.

The question is, what distance between A and B is mechanically reasonable?

Thanks.

Gerald and others have established 3mm as the minimum.
Remember the grub screws retaining the pinions need to be tapped into this remaining thickness.
Just use the 24 tooth pinion unless you are willing to sleeve the 20 tooth pinion with a metal ring.

Regards
Ross

Ros, be careful here, a DP20 gear is not the same as a module 1 - 20 tooth. see this thread. You would need to go for a minimum of a 24 tooth Module 1 gear (20mm boss - 14mm hole = 3mm wall.

A DP20 gear with 20 teeth has a diameter C of 1inch = 25.4mm
A module1 gear with 24 teeth has a diameter C of 24mm

The non-metric people use DP20 with 20 teeth, the metric people use module1 with 24 teeth - they are close the same to give diameters of 1 inch compared to 24 millimeter.

Thanks Guys.

I can see the sky clear now.

few days ago, this big boy come to home.

Attachment 11039

New tool for my garage.
Adquired in one online auction.
This is one 500Litres 5.5Kw Three phase to connect to 240VAC two phase.
I think can work with two capacitors one for start and one for work.

Thanks Mechmaters.

News:

I have gears and rack.
Purchase this in Chiaravalli Spain. (Tel.:938440099).

2x 3Meters Rack module1 15x15 20º
2x 2Meters Rack module1 15x15 20º
10x Gears 24teetch Z=24 module1
Machined the 10 gears with 14mm shaft hole and two Grub Screws. (same company)

Selecting the Grub Screw for the Gears:

Folowing the Gerald specs about 5mm hole, we can select two type of metric pitch
(Pitch is the distance from the crest of one thread to the next)

M6x1 ------- 1mm pitch----------Diametral drill hole 5mm
M6x0.50----- 0.5mm pitch--------Diametral drill hole 5.2mm

For this application we prefer the 0.5 pitch because the screw torque in the shaft is better.

Any sugest? all is ok?

Hi all.

Im making my control box but im thinking in connect the A+A-B+B- Driver signals to the Terminal Blocks or is better connect shielding cables direct to the motors.
Attachment 11185

New box.

Refurbished from one industrial laundry.

All fit perfect, but need more terminal blocks for aplications.

The cables between drivers and Terminal blocks are 1.5mm and the cable between terminal blocks and motors 0.5mm (recomendation cable thread), but the factory cables in the motor are 1.0mm. :confused: .

Now, start the Mechanic Mechmate part.

Hi Ros

Nice choice of motherboard with the embedded AMD CPU.
I ran file servers off the little VIA embedded CPU's for many years and really like the small form factor boards.
Yours looks like a ripper, AND fanless too, due to the low Thermal Design Power.

So far your are doing everything just so well - totally impressed.

PMDX 122 + 5 stppers ?
 

Hello,

could yoou please explain how did you contect 5 steppers to BOB with just 4 outputs ? Is such design already tested ?

Jan

Parallel ports have 8 bidirectional pins, 5 inputs, and 3 other outputs (4 if you count the strobe pin, but it's not as generally accessible). Most BOBs are configured to use the 8 bidirectional pins as 4 pairs of step/direction. The remaining outputs are used for aux controls, like spindle speed, turning on dust collectors, etc. If you are willing to give up two of those pins, you can control another stepper driver with them.

Jan,
If your machine accounts for 2 motors on the x axis, and with the appropriate stepper driver (like a G203V) you can share the step/dir signal for the x axis and drive 5 steppers on a machine and keep the 5 inputs and 3 outputs as Brad mentioned.

This will allow for an 4 axis machine to be controlled on a single parallel port. Currently, I use a PMDX 122 with x1 and x2 shared to allow for a true 4 axis machine on this board.

This does limit your use of the "autosquaring" feature in Mach3.

Sean

Thanks Ross, I follow your work closely.

Compactflash Card (Transcend 4GB Udma) has a 300X transfer or about 45Mb/s.
The RAM is 1GB Kingston.
