I still can't understand why you need lathe on CNC machine, just use your 4 axis and stepper motor to rotate it slowly – let milling bit do the job. If you really want CNC lathe just buy dedicated lathe and add XY axis to it to make it CNC...

the minimum "proper" lathe is something like this... shipping cost for that mini monster can result you in cost of $1000 or more in total... even that mini machine has quirks when reviewed in the net, repairing it requires you to have more bigger lathe/mill cost an arm... anything less than this is a toy imho, even this can be classified as toyish grade... Mini Lathe Machine WM210V Small Household Lathe with 600W Motor secondly it requires large amount of space or extra if you have both of this lathe and cnc separate, esp if you only do some miniaturized devices...

--- End quote ---
Yep, 40V is a deal breaker, tho I'll probably end up buying both bards for testing their coding.

It's a 4 layer board and it looks pretty empty – just admin you were lazy :D


--- Quote from: langwadt on September 22, 2019, 03:54:05 am ---the choice between rails and aluminium with wheels is the choice between cheap and good

Thing is I don't think Cbeams are bad :D Tho I might be wrong...

--- End quote ---
Yes, sadly he did not explained the difference and his reasoning


--- Quote from: langwadt on September 22, 2019, 03:54:05 am ---everything complicated is going to be a pain to program, but it the little I've looked at it it seems the documentation on the TMC is better

--- End quote ---
I'm not afraid of complexity, I'm afraid poor support/documentation on the matter.

Thank you for your time and answers, now I have to do more digging and make a choice...



Mechatrommer – Google "mini wood lathe" and you'll find what I had in mind.
