Ask me what you want to know about the TopsCNC 🇬🇧
In this topic you can ask me what you want to know about TopsCNC. I will add the frequently asked question to the main design page here :
TopsCNC Heavy - Design page
But please, read this topic BEFORE ask a question, maybe someone already ask the same question !
The goal of this topic is to stay clear, so each others can find answers too ;)
It would really be helpful to get clarification on what MAYCHANGE, NOTTESTED, and T8 to T14 indicates in the file names. Since the machine has been built I am confused by NOTTESTED and since there are two versions of the files listed as MAYCHANGE I assume the MAYCHANGE version is Deprecated and replaced by the T8 to T14 versions? Anyone that can clarify/confirm this it would be appreciated?
@jadoglio Yes I will do that tomorrow for sure
Hi @Topsie, I just posted some pics and details of my completed CNC based on your design. Thanks for everything! If you could take a look, I have a question about the collet extension I've see you use in your videos.
Thanks!

Just received some T8 lead screws. One is bend a bit. Does it make sense to try to bend it back or will it never be accurate enough for a CNC? Or does a little bend not matter?
A little bend not matter :)
@shoe Mine bend a little too, but only on the Y axis. They would make right and left feet flex where the motors are attached. I didn't like that, so I switched the rigid coupling to flexible ones on that axis and voilà - flex gone. Didn't lose any precision either.
I'm about to start mine. Do you think the gantry can handle more weight? (Or should it?) I'd like to add a laser head in the future so I'm wondering if I should beef up the gantry/lead screws right off the bat. Thanks. Et merci Topsie!
@Topsie are you planning to make the Y-Axis more sturdy in the future? What other plans do you have? Direct drive for Z-Axis? Will there be a final version of V1 and HEAVY?
@Topsie, Launching my prints tonight! On the heavy version, which "ZAxis_Cart" should we use?
The "Rear_52mm_Spindle_Holder_v1-3" seems to fit "ZAxis_Cart_small_DEPRECATED" but is not long enough for the "ZAxis_Cart_bigger" (4 vs 6 attachment holes). Am I lost? I think I am. Thank you!
Salut Topsie!
D'abord, merci pour ce super projet, j'ai commencé à imprimer les pièces pendant le confinement. Ça a été une source d'occupation géniale! Après pas mal de problèmes de livraison, j'ai enfin toutes les pièces :)
Je rencontre une difficulté pour l'axe Z de la V1 et je n'ai pas trouvé la réponse sur le forum. Il me semble que les trous pour les rails de guidage du "Front Z axis support" ne sont pas alignés. De coup le chariot de l'axe Z ne coulisse pas jusqu'en haut et jusqu'en bas. Il force beaucoup. J'ai déjà ruiné 2 roulements linéaires. J'ai vérifié toutes les options d'impression mais j'ai l'impression que le fichier posté est ainsi fait. C'est normal ? Je suis un peu perdu, c'est tout ce qu'il me reste à monter pour enfin me lancer :D
Merci d'avance pour ta réponse.
