Ask me what you want to know about the TopsCNC 🇬🇧

Salut

je cherche de paramétrer la cnc shield pour controlé ma broche d'usinage et comment faire l'installation de cable entre les deux, je vous serais très reconnaissant si vous pourriez m'expliquer svp. merci...

Hi   Sawadeekap

First of All

Great Concept     I really like it

I planed a long time to build a cnc-router  for me.

I will go with your concept. 

But as i want to build it bigger, i couldn´t get lead srews in this dimensions. I think i need to change to belts instead of lead srews. 

Did you thought about belts instead of lead srews before and why u didn´t use belts? Are they not strong enough?

I forgot to tell, I live in Thailand and there it is not possible to get this dmensions of lead-screws.

My desired size is about 1500 x 2500 mm

Gratulations again to your built

Klaus

I am currently working on Nema 23 version, with T12 leadscrew support, i think we can find 2000mm or more in T12 instead of T8

Topsie, I was having a hard time sourcing larger than 2000mm in either the leadscrews or extrusions. Curious to see what you find!

here is a 2000mm leadscrew, i can't find more for now

Bonjour,

Tout d'abord , bravo pour le travail accompli !

je compte monter ce type de fraiseuse, et j'ai déjà en ma possession 2 vis trapézoidales en lead  8mm.

Juste une question: pour les T8 de cette machine , quel est le lead ? 2mm pour 1 tour ,ou 8mm pour 1 tour ?.

Merci

A+

Hello, merci ! j'utilise du 8mm lead c'est parfait :)

Hello topsie I wanted to ask you if you can help me with the connection of the power button, from the video it seems that you also use a button but I can not figure out how to connect it. Also do you think the end of the race should be mounted? In case of how do they mount ?

Re,

Merci Topsie, je vais continuer ma liste d'achats.

A+

hello topsie, you indicate a 5A 60W power supply but if nema 17 are at 2A x 4 = 8A + arduino and sheild and driver I think they also consume.  So the power supply that you indicated and that I purchased is not small?
