Re: CSS questions #CSS
¿ªÔÆÌåÓýI mentioned those as the range of speeds you get with small lathes.? My little Unimat will eventually lose that stupid like underpowered brushed sewing machine motor for one a bit larger with Manjeet's UHU servo driver board.? Photo attached.? That's a surplus printer motor good to 3600 RPM I think.? So I'd still want a couple of pulleys to perhaps get 7200 RPM at least. ? With that I then would have 0 to 7200 RPM and there's enough torque drive.? The Unimat is so small that I believe size 17 stepper motors will work for both axis which means something like a BeagleBone cape meant for the 3D printing market would be more than adequate for driving this along with an encoder disk on the spindle. ? At this point a keyboard, mouse and display that are all collectively larger than the lathe itself have always seemed a bit over kill so once again, a smaller LCD interface with lots of buttons on a panel not much larger than my ELS would be ideal.? But it would still involve somehow rewriting the AXIS user interface for MachineKit to deal with a smaller display and keyboard with commands that ultimately use the CNC engine of MachineKit to create ELS motion. ? In the long run, whether it be for a dedicated small PC type motherboard and Ethernet MESA to parallel or the 32 bit TI processor on a custom board looking like a Beagle etc. the idea of a non-video screen and PC keyboard/mouse as a starting point is a project begging to be built.? That infrastructure then allows the buttons and the display plus an MPG knob to in essence be a custom pendant for LinucCNC but behave like an ELS. ? And with that you'd easily be able to do CSS. ?
