I am a Dutch design engineer, living in Wales (UK) and working in steel industry until recently, as my request for voluntary redundancy did get accepted. I am married, and I am a father to a little boy. I like to stay in touch with the latest developments in Computer Aided Engineering, and in work I did get to use tools such as CAD, FEA, and CFD. I now started my own company, through which I am hoping to provide for my family by designing and making stuff.

Hi. Lately there have been more offerings then when I originally published the intructable. The two most interesting ones in my opinion, are Onshope and Autodesk's Fusion 360. Both are cloud based and free versions are available, with monthly subscriptions for the more extensive versions.Direct modelling has it's advantages, but so does parametric modelling. The most powerful option is to have both available.
View Instructable »Hi. In the end I did not have to build my own drivers, as I managed to buy a set of YOUCNC drivers on Ebay. They were very cheap and they work very well. Although I have not used it myself, this might be a good starting point: https://www.instructables.com/id/How-to-make-a-driver-for-a-stepper-motor/
Hi again. At the start of a design I often identify certain dimensions which are open for optimization. By carefully building up a model with this is mind, I am able to very quickly tweak these dimensions in conjunction with immediate updates to the model. I find this incredible powerful for machinery design, although it does require some planning from the outset. If using a parametric package like SolidWorks for more organic shapes, I can imagine it would be frustrating due the lack of direct modeling tools.
