OpenBuilds Style Build

[JAZZCNC]

Would love to see the comments from Jazz when he see's these!! What a pile of ........................

I've seen many machines which use Delrin nuts and ACME screws that work perfectly fine in for the right applications, however not very good for CNC for obvious reasons plus they wear out very quickly.

Too bad you wasted some money but I guess the lesson learned is to look at technical specs and drawings. While I never spend time on designing a machine in a fancy 3D modelling software, I do spend a lot of time on looking at drawings and specifications before I order something to avoid mistakes like this. Anyway, this is the reality of DIY world. We make mistakes and we learn and hopefully never repeat the same mistakes. Mistakes are made by the professionals also even in the industry, but their DIY is called prototype. The difference is that the prototype never gets sold, so we only see the nice final product, believing that it always looked like that.

No sorry, the mistake was not listening to the advice given and making very large assumptions without a clue to what was being bought.!

If Woodknot had listened to the advice I gave and done the research on the design and components used, then made at least a 2D drawing to help with dimensions and fit then this wouldn't have happened.
Also, if he had started a Build thread sooner and posted the components in this thread rather than buying first and starting threads all over the Forum there was a much higher chance one of us more experienced builders would have caught this before it happened.

I don't agree with you regards not designing using 3D models.!
All my machines are 100% designed with 3D models, even the ones which never get built and I rarely make mistakes that actually make it to the actual machine as they are all caught in the CAD model. It actually saves wasted money on R&D as a large chunk of the problems are caught on the Model so parts are not being scrapped, (the Camming of parts is another story and I make mistakes regularly) 3D models allow me to see everything and how it fits together so this doesn't happen and the Finished Model is an exact replica of the real finished machine. So much so that all the machined parts are taken directly from the model into CAM software.
Also, if design changes are needed for any reason, it's often a simple tweak and the effects of the change are reflected and obvious instantly.

3D Modeling, even a basic model, can and DOES save you time and money in the long run even for a one-off machine.! This case is a classic example.?

If WoodKnot had modeled just a basic model of the machine using off the self Models for Profile and Bk bearings etc which are provided by suppliers then it would have become obvious they wouldn't fit and this expensive mistake would have been avoided.
Also, it shows and removes the chance of any hidden surprises further down the road which at the moment he will only find out about at the time he comes to this part of the build, which is often too late and again becomes expensive.!

Also, if the machine was modeled any plates and parts which he required machining by outside sources he would have models to give the engineer and reduce costs.

Lastly, at some point in CNC then sooner or later you are going to want to use a 3D model so taking the time to learn 3D modeling while designing the machine will pay off for using the machine and creating G-code quicker.
