Man I definetly need to take some sleep....

 

It definetly did something this time. Thanks for youre help guys. I was ready to just go back to Estlcam and windows haha.

If I go to Applications -> CNC there are only two options there is Documentation and G-Code Quick Reference. There is no LinuxCNC application does that mean somthing went wrong with the installation? I did a restart same thing.

 

Hallo Joe,
ich bin aus München und habe auch ein 4060 mit Parellelport. Wäre sehr interessiert für so ein Treffen. Auch privat zum Austausch, wenn du Interesse hast kannst du mich anschreiben.

Gruß Jerry

Hi Todd,

Thanks for your response — I’ll definitely give that a try, as it feels like my last resort with this current setup.

I've already disabled everything I possibly could in the BIOS. The only things I haven't touched yet are the memory timings and voltages. If this doesn’t work either, I’m honestly not sure what else is left to tweak.

I'm also considering switching to a Mesa card, possibly the 7i76EU, but I have zero experience with Mesa hardware. I’ll need to figure out whether it will work with my three DM542A stepper drivers, and also with my VFD, which is currently controlled over USB using: `loadusr -Wn vfd hy_vfd -n vfd -d /dev/ttyUSB0 -p none -r 9600`

Things i disabled next to the obvious, like settings for fixed clock speeds (fclock 1066, bclock 1000) disabling power management and disabling hardware that is not being used (BT, Wireless, serial, audio, fancontrol (disabled fixed on 100%)):

BIOS Settings (set to Disabled):

SMT / Hyperthreading
→ Disables logical cores to reduce cache sharing and latency spikes

C1E, C6, and other C-States
→ Prevents the CPU from entering sleep states, ensuring consistent timing

Streaming Stores Control
→ Avoids aggressive memory write optimizations that can disrupt real-time behavior

DRAM Scrub Time
→ Turns off background memory error checking to avoid unexpected memory bus usage

GMI Encryption Control
→ Disables inter-chiplet encryption on Infinity Fabric to reduce overhead and latency

XGMI TXEQ Mode
→ Prevents signal equalization tuning that could introduce instability or variability

DRAM Map Intervention
→ Disables memory remapping logic that can introduce unpredictable latency

DF Sync Flood Propagation
→ Prevents error broadcasts across chiplets, reducing the chance of system-wide stalls
