I'm still wanting Stepstick/Pololu screw terminal breakout boards for easy and rugged connection of external stepper drivers. I could probably design some, send off to OSHpark or somewhere and have four of them for a $20 in a couple of weeks, then I'd have to buy the header pins and connectors. And for that there would be four in existence.
Would be better for someone already in the business to have a batch made for economies of scale, and market them on their website... "Have you ever wanted or needed professional, industrial grade connections of external motor drivers to your RAMPS, CRAMPS or other controller that has StepStick or Pololu stepper sockets? With these screw terminal boards your 3D printer, milling machine, router or other CNC machine will have exactly the same reliable, rugged wire connections as industrial CNC machines. Connect and disconnect drivers without fear of bending or breaking header pins. Works with all StepStick and Pololu sockets." I'm not in nor do I want to be in the business of designing and selling electronics or related products. Though I have given some thought about figuring out what it would take to make a USB-C ExpressCard for laptops without built in USB-C ports. USB 3.x to USB-C adapters *just don't work* for some USB-C devices. They need a genuine USB-C controller. There are dual USB-C PCI Express x1 boards for desktops. ExpressCard includes a PCI Express x1 bus. So WTH are there no USB-C ExpressCards? If one company has them made, and properly informs the public they exist, then demand will happen - especially with Windows10's ability to run quite well even on the oldest laptops that have ExpressCard slots. (It'll run quite well on even older ones, like a 13 year old Compaq nc8430, with Core 2 Duo CPU upgrade.)

There is Machinekit, which is a branch of LinuxCNC, that runs on the Beagle Bone Black, and has done so for something like 5 years. I make the CRAMPS board that mounts up to 6 Pololu stepper drivers to it, and level converts all the other I/O for it. So, a very compact package and you just need to wire the motors, limit switches, etc. to it, and provide a power supply. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
