Basic Information: Printer Model: Sovol SV06+ MCU / Printerboard: Manta E3EZ Host / SBC: CB2 klippy.log klippy.log (91.4 KB) Issue: … I am using the above to determine max acceleration and speed of X and Y. I have slowed the printer all the way down to 50 for max speed and 100 for max ac…

First off, could you be more descriptive in what your problem is? What do you mean when you say you are “losing steps” and how do you know? Along with the TEST_SPEED macro from Elli’s tuning page, you have a lot of macros running in your system. The first thing I recommend to somebody having prob…

After running Elli’s Test_Speed the starting MCU position and the ending MCU position are at minimum 4-6 microsteps apart. From what I understand from Elli’s instructions is that the beginning and ending MCU coordinates should be less than 1 microstep apart. I can provide a picture tomorrow if need…

My understanding is a bit different: We have to differentiate between “digital steps” as produced by Klipper and mechanical steps as executed by the motor. On a typical bipolar stepper, it takes 4 digital steps to move the rotor one stable mechanical step. A stepper can only lose mechanical steps …

[20250126_123855] With none of the macros disabled. [20250126_124327] With all the macros disabled. The numerical differences are nearly identical at about 256… or 4 steps. (Sorry for the second picture being so crooked)

Do you know, that you can Copy&Paste from the Mainsail/Fluidd console? There is no need of making photos.

Increasing Y run_current to 1.2 resolved the issue for Y, but not for X

Hi @JimmieNeu ,

It looks like you’re using 64 microsteps on X and Y. Stepper motors only lose full steps, not microsteps, so as long as your values are no more than 64 off in either direction, you haven’t lost steps.
