New CNC PC Pledge
The Current PC running the CNC Mill is a Pentium 4 based system. It crashes a lot, is dated, sluggish and not nice to use.
Anyone who has used it will tell you this.
The aim of this pledge drive is to refresh the hardware with something much faster that will make the CNC machine much more responsive and nicer to use. Refreshing the hardware also gives us an upgrade path to a Mesa card should we decide to buy one in the future. The software setup will remain identical to the current system.
Current PC Baseline
This is what the new hardware needs to beat. Latency is more important that raw power hence why we are not pledging for an i7 or similar based pc.
A new PC will be built from scratch. The PC will be based around the J3455 Motherboard + CPU combo. It has got some good recommendations on the LinuxCNC forums.
