Best new Hardware for linuxcnc

Good evening, I would like to know for sure what hardware I should have to run linuxcnc to drive a NVEM rt1052 with remora to not have latency problems with the video test on youtube while the machine works.
What do you think about an RK3588S? Is there something cheaper with the same or better performance?
Thanks and sorry so much.

Lenovo M72e with an i5, I use one as my test bench. Even works well using a parallel port using software step\direction. Be careful as some may have a G series CPU, but these can be swapped out for a 3rd gen i5.

Odroid x86 H series work well, that what my mill runs with, H3 in my case.

If you want to use a arm based SBC I'd go for a RPi5, images are available and work with no issues.

Honestly the best bang for buck is a ex corporate PC.

With the RK you have to build\source your own RT kernel.


I have seen your thread, have you actually tried running a config with the PC you have ? In a real life situation you are not going to be watching 4K youtube videos when machining a part. Just give it a go and don't get so hung up on latency. With a setup using the Parallel Port it is an issue but an external step\dir generator board shouldn't be so picky about latency nor should it require a base thread, servo thread should be all it requires..

What you may spend on a suitable new PC (especially if you are considering an Rpi5) maybe equal in cost to a Mesa board...and whilst the remora project is well supported and has had a lot of work put into it I'd know which way I would jump.

I've had luck using AUD $40 Spartan 6 dev boards running Hostmot2 firmware using either an SPI or EPP interface. Apart form Mesaflash issues I'm also having success with Ethernet as well.

thank you, the problem I'm experiencing is latency when moving windows, I wouldn't want a more complex gcode, I hear ambiguous noises coming from the stepper even if it doesn't go into error when I move a window. I'm already recompiling the kernel to version 6.12.28 to verify that there isn't something wrong there. But the problem is always the video card! I would really like to be able to make it less resource-intensive, I've already tried removing hardware acceleration without success

Have the servos been properly tuned ? Steppers are basically wire up and forget, servos are a different beast and require tuning or you may hear grumbling noises.

stepper sorry....
