Basic Information: Printer Model: BLV MGN12 MCU / Printerboard: DUE + RADDS Host / SBC Raspberry Pi 3 printer.cfg (7.6 KB) Hi everyone, I’m still relatively new to Klipper. I’ve got everything running now, except for the “Input Shaper” issue. The ADXL345 from Fysetc is now running, which …

This is just a new IS test, nothing to worry about.

So you mean it’s ok that this test goes so slowly? [shaper_calibrate_x] This is the Picture from my IS. I took the 3Hump_EI with 83,2hz and an Accel of 5000. Hope i done the right. Thx for answer

Well, that only mean that in your case here is not enough resonance power. So, there is mostly no peaks. Generally good graphs should be in a scale of 1e4 (~1g+) (>10000) In your scale, there are 1e3 (0.1g) (~1400), which is just looks like a normal vibration. Probably for good measurements, you…

Again many Thx, i will try that.

Is this perhaps due to the mks servo42c drivers (closed loop)?

[image] Smasha: Is this perhaps due to the mks servo42c drivers (closed loop)? Most probably, you will not be able to tune or use IS with a closed loop. Simply because they are not compatible with each other. IS assumes there is an open loop, and we do some physical hacks to make the system…

Oh, okay. I could go back to some TMC2209 Drivers instead. Back then, I had a lot of problems with Repetier, including layer shifts. That’s why I upgraded to closed-loop drivers. Maybe i could change my Due+Radds with a BTT SKR Mini E3, V3.0 . In this case i could use the TMC2209 with UART But …

There are a few considerations. First, you ran several resonance tests for the same axis sequentially, and the script picked up all the results and combined them together. You can retry the test, after powering off and turning on, the previous test results will be deleted. And you can also try incre…

Such a spectrum could also mean that your axes are actually binding or not moving freely. For a better understanding see Interpreting the Input Shaper Graphs
