I mean when you see holes drilled like this on the spindle mount what can you expect. Attachment 22826

They are to stop you assembling it incorrectly

Hi all, thanks for all your input and sorry for not responding sooner, I have been driving back for my holidays.

So a lot of interesting comments. Which has given me a lot more to think about.

Going with square rails is definitely a consideration. I did look at this some time ago the longest I need is about 3500mm. Is there a specific grade/ standard that I should be looking for?

I leaning more towards steppers for the moment purely because I have done a crap load of research into them, cost and the mechmate site has a lot of support. From what I gather servos are better and upgrading the machine later (when the machine is paying for itself) will probably be on the cards.


With regards to purchasing a Chinese cnc. When I decided I was going to build a CNC It was for a number reasons.
1 By building it I will more control over the precision.
2 I would be able to maintain and upgrade the machine myself.
3 The whole building and commissioning process would stand me good steed in understanding how to operate it.
4 Cost, during the build and in maintenance during the life span of the machine
I could be wrong but I don’t see how a Chinese cnc for under £10K could do that.

I forgot to mention before, on the software front I have been using Sketchup pro for many years, more recently I received a seat and started working with solidworks.
Again because I have no experience with parametric cad software and I intend to use the cnc for flat panel cabinet work and true 3d stuff. Am I looking to two separate types of software for this and also what cam programs that work well with them?
I am committed that I will have to spend a lot of time getting up to speed with these programs, I just want to make sure I choose the most applicable. Any thoughts and advice would be great.

Thank again all for your comments and thoughts.
