Is there a way to set the speed of movement during the G28 macro? The default Z movement speed is resonating with some part of the printer and is particularly loud. I checked all the fittings and fasteners and can’t find the cause. I’m hoping just to drop the Z moves out of resonant range to resolve it. ---

You may look here for `homing_speed`: [https://www.klipper3d.org/Config\_Reference.html#stepper](https://www.klipper3d.org/Config_Reference.html#stepper) Don’t make it too fast to: - Prevent crashes against the endstop - To give the MCU time to check the endstop. If you use `safe_z_home`, you may look here: [https://www.klipper3d.org/Config\_Reference.html#safe\_z\_home](https://www.klipper3d.org/Config_Reference.html#safe_z_home) ---

Hi, default homing speeds for all axis throw no issues. However when control of Z axis is made via gui control tab or through BED\_SCREWS\_ADJUST, etc… Z is driven too fast, skips and tries to sing. Where should I be looking to change this? Many thanks. ---

Hello @poonholder ! Can you share the klippy.log? ---

Indeed, apologies for my delay. Im sure im the issue, setting incorrect max vel, max acc, for z in config. But is there a global setting for the GUI tabs for axis movement? It grinds when positioning the z axis alone. Printer is a two trees pro, z is build plate. The federate is to high when using BED\_SCREWS\_ADJUST also. Other than that, whilst printing it is seemingly ok. Many thanks. Uploading: klippy-7 feedrate stall.log… ---

If the Z speed is too high, you can set it in the `[printer]` section of the printer.cfg ```auto [printer] kinematics = corexy max_velocity = 250 max_accel = 4000 max_z_velocity = 15 max_z_accel = 25 ``` ---

Many thanks Eddy, are the current settings not awfully low though? ---

Just give it a try and set it to `1`0 or `5` ---

I will do, many thanks.
