Hi Pierre!

Spark spouts out!? If I can help you with some translation of specific elements, let me know.
I am, myself, having an eye at Gerald's design and all the forum participants information sharing on the forum.

Merci encore une fois Paco !. Peu de francophones sur ces forums...c'est dommage !Concernant le projet de la mechmate j'ai quand même un doute sur ma capacité à réaliser la partie electronique. Penses tu que cela est accessible pour un débutant?. La partie mécanique est comprehensible.
Voici le site web d'un ingenieur français qui a concu sa propre CNC grands formats avec de bonnes idées (comparatif avec shopbot).Je vais me mettre en contact avec lui et lui présenter le projet Mechmate.

Pierre, The website given in your earlier mail looks very interesting but unfortunatly it is only in French. Do you know where we could find a English translation.

try Google translate; might not be 100% readable though but may help figure the basic content.

Paco,

Comprends tu l'astuce de Benoit Desbrus concernant la position de la glissiere par rapport au moteur sur la page web http://cncloisirs.com/Machines/Beno%eetDesbrus ?
Il trouve cette solution plus interessante que sur une Shopbot.J'aimerai en faire profiter Mechmate en Anglais si tu penses que cela est interressant.

Pierre,

je n'aime pas le principe d'exposer le crémaillère de cette façon. De plus, si j'entrainerais le X de cette façon, le placerais le moteur au centre pour distribuer la torsion de l'arbre... par contre ce dernier système est intéressant, mais je le préfère dessous plutôt que dessus. Je sais, ça complique les choses mais ça protège les crémaillères.

Je partage son point de vue sur la torsion du support de moteur lorsque poussé/tiré par un ressort. Par contre son système me semble ""trop"" complexe. Sur ma machine, j'ai ajusté le positionnement du moteur de façon à compenser ce problème.

Pierre,
tu peux considérer des solutions déjà prêtes; Ascesnsion 1000 et Mach3 enclosure, ShopBot aussi peut te vendre un kit moteurs, contrôle et logiciel seulement(en deux versions)... et il y en a d'autre; cherche avec le mot clé RETROFIT, CNC CONTROL ou encore # AXIS CONTROL...

Right at the top of this thread is a link to Google's english translation. Subsequent links out of that page are also translated.

bonjour Normand !!.(avec du retard).
Je viens juste de démarrer la réalisation de la mechmate : j'ai commandé le charriot (decoupage laser) chez Kim Mortensen, en Norvege trouvé sur le forum. J'ai pris contact avec mon ferronier local pour la réalisation de la table. Pour la partie electronique, je vais utiliser les composants de chez techlf.com.Plus de photos dès le demarrage.
Je vais essayer de trouver sur le forum l'adresse d'un revendeur pour commander l'ensemble des petits composants : cremaillere, porte cable....

Hello,

i have received my two orders last week :

- Order from Kim Mortensen for the laser cut parts.
- Order from Superior Bearing company.
The two buyers are greats !. No problems at all trought paypal.

I have bought all the parts concerning the table (dimensions : 2800mmx2070mm for french max wood boards)I will send to you some pictures next week.

I'm quite nervous when i see the detailed pictures of the electronic box !: i'am not an electronic professional guy !But i'am lucky to have close to my town this new internationnal company, provider of electronic cards and engines for CNC tools (website french and english) : www.techlf.com/

Thank you Gerald for all your work !.

I had now a translation in french (excel listing) of all the Gerald drawings from french mechanical engeneer and the listing of all the parts with dimensions.

Bye
Pierre GRAND, architect in France.

Red face Frame photos

Hello Gerald and Paco,

I have finished the steel frame ... a big step accomplished for my 2800mmx2070mm real cutting area mechmate (french mdf boards dimensions !). i'm working on the Z axis at the moment : i will finish it at the end of the week. I need to order the gazlift...i have read the Gerald precisions article to choose the right one...at www.airax.com/ in France.


What make me nervous at the moment :

1) The choice of a motor with or without a geared box (the price is really not the same !!)???Is there a big precision cut difference ???

Thanks. Pierre.

Not as big as the difference in price!!!

You can always start with non-geared motors and change later if necessary. That is what we did, but so far it has not been necessary (for us) to add gearboxes.

Our effective pinion diameter is 24mm (metric M1 Z24). Directly driven, that is 2000 pulses per 24 X Pi mm = 26.5 pulses/mm [673 pulses/inch]

Mechanical Mechmate phasis complete...!

Hello everyone, Hello Gerald,

I 've just finished yesterday the mechmate frame details and finished the z axis. Everything is ok to go on the next step : electronic and wiring management (done by a company with Techlf components).
The way all z components work together along the vertical axis is very impressive !! (motor, rack and pinions, the gaslift and the string). Just one questions for Gerald :

- Is it possible to put industrial wheels (with stops) under mechmate feets to move it in a small area (my workshop 4mx12m)??? Maybe problems of stability during the cutting ???

Thank you. photos in few days maybe with paint...in dark grey(old steel paint i have in stock...sorry for the blue).

Bye,

Pierre.

The wheels will be okay - they will not affect cut quality.

Hello everyone,

My Mechmate has been move in my future office/workshop (whithout walls for the moment !) so i had to paint it quickly. I will install the electronic in november .... i hope if my job let me the time ... The wheels have been welded on a steel plate and welded on the main frame... it is very practical.

More photos and comments in 2 weeks with my RDV at Techlf Company, near Toulouse with Laurent Fouga.

Bye,

Pierre.

Wheels references + electronic parts quotation from Techlf

I would like to add to my last message the wheels company i have used : Blicklé, german company at www.blickle.de.

and few words concerning the TECHLF quotation : See the web site to have parts details ...

- only 3 motors inside the quotation because i have ordered one before to check the mechanic.
- one Elte, professional spindle include ( the smallest of the company).
- the electronix box include .

When you received the ready made box, install the motors on the mechmate and turn on the power button ! . That's all i was ready to do concerning electronic. After spending a lot of time and (quite money) making the frame, i wanted to be sure the electronic parts works correctly and wanted to have quickly someone to call if not. The price is very correct to my point of view... compare to other all in one package...


Bye,
Pierre.

The trees in the top photo must be reflecting off the fresh paint
Sorry about the army - I had to serve in the navy and there we knew what grey paint really looked like.
