Hello everyone, I entertain the idea of using klipper with closed loop axis control. I did a little research, but I ended up a little confused. In my understanding it should not be a problem to use closed-loop drivers instead of open-loop drivers. I dont see that Klipper would even have to know abo…

I think this is mainly a question of the quality of the closed loop system. I am myself considering a similar move, but I would prefer actual servos (JMC has some affordable even in NEMA 17 form factor). Such systems are often used in CNC milling machines which have a higher requirement for the accu…

Not having dug too deep into this topic but as far as my understanding goes there are two philosophies: Mechaduino approach as per above link: Klipper runs on the dedicated stepper MCU board Klipper manages PID, open / closed loop etc. Only roughly developed and not fit for daily use STEP / DIR …

I’m running MKS S42C for the x and y of a CoreXY. They are defined as A4988 and get the step and dir from the printers mainboard a BTT GTR. Works absolutely fine.

Did you need to short the SLP & RST pins on the stepstick adapter? Apparently A4988 drivers need to have these two pins shorted, but I’m not entirely sure about the MKS SERVO42C or SERVO42D.

I’ve been told by people smarter than me in both the Armchair Heavy/Engineering and creapunk Discord servers that servos, in Klipper’s current state, are not super reliable due to how Klipper’s clock is implemented and the lack of clock sync between MCUs - apparently this aspect of the firmware is a…

Hello @x_jaydn ! Thank you for your input. Due to the age of this thread and the ongoing development, this thread is closed.
