Projects Not Quite on the Bench
I am getting enthused with my many design sketches for the next CNC machine. It has been hard for me to scale back on size with my design schemes. It all relates to my own advice that I must have a product I want to produce and size the machine to accomplish the task. What I really must do is to keep it within a size constraint that will fit into my residential shop area. It still looks like ~ 25 x 25 or so working area with larger overall dimensions.
There have been lessons learned on the first machine I built both good and bad, which in a way makes the bad discoveries a good learning experience. Boy is it ever true; the bigger you want to go the much more it is going to cost!
On the first machine I found out how critical perfect alignment is for a machine just to be able to move. I am planning for that on the new design. Linear slides do not tolerate poor alignments and deflection.
It is too soon to release my machine design thoughts. I don’t have all the details worked out as I like to design/build. I am considering doing some drawings this time. It will be a more serious design than the first machine and that may gather interest from other hobbyists. I am definitely aiming at the hobbyist user (me) but the design will be able do serious work. A small machine shop is definitely required to build this one. I plan to make some of the more costly parts. (Mmm… maybe a kit design?)
I am currently working on the new CNC controller and I will grab some pix of that as it goes together. Electrically it will be very much the same as my second controller which continues towork very well on the Taig CNC. I enjoy the electronic design effort as much as the mechanical. Stay tuned…
