Spindel Speed stimmt nicht #141

Closed TOKENone7472 closed 2 years ago

TOKENone7472 commented 2 years ago

Habe das Problem das die Mittlere Spindelgeschwindigkeit nicht stimmt. Ich benutze STM32F446RE und Arduino Shield CNC PWM Signal über Z+. Mittlere Spindelgeschwindigkeit habe ich 1,98V, bei Max Drehzahl 3,29V. Die Mittlere Spindelgeschwindigkeit sollte doch ca. 1.65V betragen oder ? Ich danke schon einmal für Tips und Feedback.

My 446 Nucleo board outputs spindle voltages that are spot on. Which board map are you using? Spindle settings?

Unbenannt (2) I have 24000 RPM Spindle PWM frequency 400Hz

Signal über Z+

This is the default pin, D11?

I have verified the output on that pin with your settings, both with scope and multimeter. Do you measure the voltage when the pin is not connected? Can you check with a scope?

problem found. It was my mistake, I built a voltage converter and made a mistake with the capacitor. Everything great now. Thank you for your help. Greeting TOKEN_one
