hey guys, I'm back from the grave.
Instead of wasting my own time to do research on the topic I'm now paid to do it :)
Anyway, I now work as a metrology engineer and I'm trying to acquire a 4x10...

what you need to know before anything is the max weight on the structure. That means checking for worst case scenario. Do you plan to have any crazy party with 20 people on there? How much snow can...

va voir chez Addison electronique a montreal
mais je ne pense pas qu ils aient de gros moteurs
Mon conseil:
utilise un vieux P3. Fait un clean install avec Windows XP (pour utiliser Mach3) ou Linux Ubuntu (pour EMC2). Ca va etre ton contrôleur.
Ensuite pour le reste de l'électro, je te...

enjoy!
never heard of anybody
seems like the main problems are controlling the motor, cost and strong magnetic field.
also called energy chains systems
thanks for the help, but I need a subscribtion.
I really dont feel like paying about 300$ for a piece a paper this is most probably useless, like most ISO norms

personnal opinion here:
Since I have spend the last months trying to design an highly accurate machine, I must say that in order my priorities for the perfect material are:
1. Dimentional...
woah! so you are using a bunch a small linear rails? Are they actually sections designes to be assembled?
its it impolite to ask how much you paid?
yes exactly.
But the challenge here will be to get a good surface on both top rails AND make sure they are the same level. Easiest solution would be to design some kind of runner between the 2...
