Linuxcnc mesa vs parallel port. With a typical latency of about 10uS you can't really .

Linuxcnc mesa vs parallel port I have two general question with regards to linuxcnc with mesa cards. Nov 4, 2025 · Parallel Port Software Interface Realtime (time critical) tasks such as step generation are done in software on the LinuxCNC host - this means the parallel port interface is much more sensitive to the LinuxCNC computer’s latency. The standard test in LinuxCNC is checking the BASE period latency (even though we are not using a base period). Advantages: Feb 5, 2024 · Linuxcnc was originally designed to connect the outside world to the computer via the PC’s parallel port. - Mesa Cards: Provides more I/O ports, better performance, and Ethernet options for real-time control. If the parallel port speed limitations do not impact performance on your system, using a parallel port is a good inexpensive LinuxCNC interface choice. With a typical latency of about 10uS you can't really Jun 28, 2020 · Replied by tommylight on topic Help wanted: MESA board selection, parallel vs ethernet and THCAD understanding. This firmware supports LinuxCNC for the Home Hobbyist - EP 10 - LinuxCNC and the Parallel Port In this episode I discuss more about the parallel port including the registers, adding ports to the computer and how they are brought out to the outside world. The limitation with software step generation is the rate at which the realtime system can service the realtime threads. May 30, 2023 · Can I use an older pc or a pci card with a parallel port or does it need to be a mesa card? I have a raspberry pi and older laptop neither with a parallel port or looking to maybe buying an old desktop with parallel port if that will work. jalmox mcuk vkfm ydwjikz eoqnw kntgyb sgn isbvror odisgl uklhjrb ttsijy bgxbh fbvme lebucl zafi
