hi terje, sorry for late reply , i've been tested it with the last firmware , but it seems that i cant do thread , it always shown up an err.41 (GcodeSpindleNotRunning) eventhough my spindle is running , and most of my G96 or CSS do a lot of 1 feedrate ( maybe its because my spindle not soo accurate ? , but after try to add override ( +10 %/-10%) in feed , the CSS feedrate can back to normal , idk why though ?, anyway , before im using the core version of "20240127" and it works normally

Hi,
I have the same issue.

After a long time I could not cut threads anymore, I saw that IOSender does nor show the rpm input.
I changed board (T41U5XBB with spindle sync), Encoder and then, after having no success, the Teensy,
The digital inputs of the Teensy died for an unkown reason.

I downloaded the latest version last night.
IOSender show me correct rpm, I measured the indexsignal, it's there.

My lathe is worthless without threading capability, it would be fine to get a hex-file for a previous version of the T41U5XBB with spindle sync.

Tentative fix commited.

Could not wait...
Downloaded over webbuilder as T41U5XBBSpindleSync board.
IT WORKS!

Thank you terjeio, you saved my weekend :-)
