Z轴不稳定？

[auxp]

The Z-axis is unstable, and after working for a period of time, the Z-axis may sometimes lose steps and become higher or lower than before

Which board?

[auxp]

I modified it myselfPCB

[terjeio]

Ok, is it using RMT or I2S for the step pulses?
And how long does it typically take before steps are lost?

I assume you have already eliminated hardware issues such as binding, or configuration issues such as too high acceleration and speed?

#120

[auxp]

Will acceleration affect?What I set up is 200.
maximum speed 2000.
Pulse 800。
Adjust the speed during work to 300-500%

Ok, is it using RMT or I2S for the step pulses?

This is about how the ESP32 is set up: is the stepper drivers connected via shift register chips (I2S driven 74AHCT595) or directly to the processor pins?

Will acceleration affect?

Acceleration, speed, stepper current, stepper type - all can affect the max rate. As can binding - are there any spots where the Z-axis does not travel freeely as it should?
