Cool nice mod Eddy. What do you make with your machine? Furniture?
Firewood :thumsup:Quote:

I'm planing on making my first CNC router with the initial goal of cutting woodwork joints. Until I read your post I was considering making a machine with a spindle mounted on a bearing to allow it to rotate from being vertical or horizontal. My thoughts were that I would find it easier to clamp and align my workpieces horizontally to a raised work surface on the bed than vertically. This would also allow me to machine joints in the ends of long workpieces (2 m in length for beds for example). Have you ever seen a spindle like this and am I mad to consider it?
You mean like this ? http://www.cnc-toolkit.com/gantry_router.html
Not Mad but not as easy has you think to do and keep a ridgid and accurate machine. The link eddy posted is to a 5 axis machine that is both expensive and complex to build, let alone generate G-code. Certainly not something I would advise any one new to CNC to dream about taking on for a first machine.!Quote:

But in practise there's quite a lot of time invested in setting up your spindle so it cuts true in both X & Y planes and gives a nice flat bottom cut parallel to the bed surface.
So any spinning device will need to be very well engineered so it's repeatable if want any decent accuracy. Then you have the fact you'll need to spin it 90deg in 2 planes to be of any use which adds to the complexity.!!
While I see why or the appeal of what you want then NO it's certainly not something you want to be taking on for a first machine believe me.! . . . The machine design Eddy used is a good tried tested design with one exception in that it he should have listened to his uncle Jazz and made the top rails longer. . .:hysterical: (Soz eddy couldn't resist) and used the end of the bed for clamping.!
Thanks Eddy and uncle Jazz. I really like the system you built into the base of your machine Eddy - thanks for sharing it. The idea I had for rotating the spindle is as uncle Jazz describes. I'll put together a drawing and post it on a new thread where hopefully some members will throw some mud at it. I was thinking of using strong and accurate bearings in a housing like the fixed end of a ball screw. Thanks again for your inspiration and showing what you've done. I'll have a look at Eddy's build log.
You won't be laughing when I put a rotary table in the same hole :thumsup:Quote:

Gerry, I hadn't forgot about your software but l'm writing some applicable scripts for CamBam first, if the outcome is bad however I know where to come.Quote:
