The various goings on in my workshop
Having finally decided on a layout for the plate in the control box, I decided it was time to drill and tap the holes for the motherboard and stepper drivers. The plate itself was previously used for something else, and so there are other extraneous holes dotted around the plate. 16 x M3 holes later,…
Next up were one of the bearing mounts, 3 of these are required as well. Here is the model of the mount. First I cut about a 60mm piece from a bar of 2 1/2″ (63.5mm) x 3/8″ (9.25mm) flat bar, this originally came from ebay seller diamondengineeringsupplies at a cost of £14.76 for an…
I finally decided to start making the mechanical parts for my CNC conversion. This is a drawing showing various stages of axis mount evolution in exploded form. The ones nearest the middle are the ones that I am actually going to build, starting with the stepper mounts. I have decided to go with 60mm square…
Having successfully installed the OS, my next step was to try and reduce the number of writes that were likely to hit the CF card, this involved moving many of the logging and temporary areas to use tmpfs and also turn off writing time updates every time a file is accessed. This is all documented…
I have been umming and ahhing over which stepper motors and drivers to buy for my mini mill for over a year now and not really making any progress on making a decision. The other day I was comparing prices of nema 23 stepper motors once again when I came across some for sale by…
