USB PARALLEL ADAPTER WINDOWS 7 SERIAL
I mean it’s 2017 and a brand new laser engraver comes with old school centronics & serial (note the serial connection is so slow that it sometimes times out or it’s a firmware issue in the laser engraver) ,oh they did include a fake FTDI usb serial adapter but windows driver update took care of erasing the PID & VID.Īsk Hackaday: What’s Your Worst Soldering Job? 111 Comments In that case we used a windows XP virtual machine and printer sharing, the USB printer port adapter is handed over to the virtual machine and that then shares that printer over the network(virtual network), a complete hack IMHO and not what I would expect of a brand new product. Mercury laser products suffer these issues still, worst part is the printer driver that comes with the device (purchased last year ) is still windows XP based and not Win 7/8/10 with security catalog, the newer OS does not allow this USB port/driver combo at all, XP was the last version to allow this behavior AFAIK.

One last remark, a true shop will have a minimum of 2 mills… one with a metric cut screw thread… and one with a US standard thread.Ī lot of ebay USB to Parallel /centronics adapters have nasty fudged drivers with timing issues & compatibility problems with software that wants to talk direct to hardware. Stick with the PC LPT method, and dedicate the machine for driving 1 and only 1 mill. The are not meant for CNC mills, and you will never get it to work reliably for the mentioned reasons. While Arduino and the like can do a lot for 3D printers as a gcode parser, they were designed by hobbyists… so make many inappropriate assumptions about physics. I have seen people try SBCs (Raspberry Pi etc.) on CNCs, but since they lack a true internal RTC they are just as problematic for timing. However, Mach3 is easier to setup, so hobbyists think they are saving time… but they are wrong… and you can’t argue with them because it sorta works for the level of work they do. Posted in cnc hacks Tagged cnc, parallel port, Sherline Post navigationĮMC/LinuxCNC kernel modules does things Mach3 couldn’t dream of doing because Windows DDK/SDK has far less stable timing from the sand-boxed API and layers of task schedulers.ĮMC was originally built by Darpa, and can actually do hard problems like maintain consistent cutting speed in a spline curvature. Still, for something small and relatively cheap, the Sherline is well-regarded, and with this little dongle you can actually use it with a modern computer. The Othermill is great, and Inventables X-Carve and Carvey are more than up for the task. There are a lot of choices out there for a desktop CNC machine made for routing copper clad board, wood, brass, and aluminum. This application generates the step pulses, but the timing is maintained by the dongle no real-time kernel needed.

the application used to control this dongle is a hack of the EMC/LinuxCNC project written in nice, portable Python. The software is where this really shines. It’s fast - at least as fast as the parallel port in the ancient laptops we have sitting around and plugs right into the CNC controller box for the Sherline. With a bare minimum of parts, this chip converts USB into a parallel port for real-time control. The core of this build is the rt-stepper dongle based around the PIC18F2455 microcontroller. Instead, he built a USB dongle and wrote the software to turn this mini CNC into something usable with a modern computer.įirst up, the hardware. While some of us still have a Windows 98 battlestation sitting around, doesn’t. There’s a problem with it, though: normally, the Sherline CNC controller runs off the parallel port. If you’re looking for a small, benchtop CNC machine for PCBs and light milling the ubiquitous Sherline CNC machine is a good choice.
