Setting Spindle 0 on novaturn
Posted: Wed 14 Oct , 2020 19:19 pm
I am interested in setting a point that the spindle will always return to when stopping, using the hardware on the machine, is this a possibility? So for transparency, I am considering making a device to automatically unlock a manual chuck, pull a bar forward, and then lock it once again. I have toyed with the idea of mounting a pneumatic chuck on this, but the cost of that, along with no pass through means that I would still need to come up with some kind of automatic loader. If the machine is capable of this, I assume there is a certain code to control it. Alternatively I am considering a far less elegant solution involving a "controlled crash" where the spindle is stalled in a known location, and then the square spindle key is inserted. This could be done as the spindle is spinning down with a bit of careful timing, but I don't like the idea of any impact being put on the bearings like that. Any thoughts on a way to accomplish this would be entertained!
