Any way to slow down X-axis repositioning?
Forgive me, if this problem already has been answered.
I recently got my first Prussia i3 MK3S with MMU2S, and I generally loves it.
BUT
I am currently printing the parts for the IKEA Lack enclosure, which takes many hours, and my wife is complaining about the noise at night. When I enable ‘Stealth’ mode and lower the speed to 25% it is quiet enough, if it wasn’t because the repositioning of the X-axis/heat bed is done at full-speed and not the 25% which seems only to apply to printing operations.
QUESTION:
Are there any settings to adjust then speed of repositioning the X-axis (travel?) and if so, is it adjustable during print (Tune menu) or is it a general setting?
Thx in advance

You can set maximum speed, acceleration, and jerk values that will affect movement of print and non-print (travel) moves using gcode commands in your startup gcode.
It might be more effective to isolate your printer from whatever it is sitting on. To see if this helps, try placing the printer on a solid surface (like the floor) to see if it's quieter. If so, whatever your printer normally sits on my be vibrating in resonance with the print frequencies, and isolating it will greatly reduce noise. I've done this with a 17x17 inch paver. Others have used marble cutting boards and other weighted objects. The trick is to:
- Increase the mass of the printer to dampen vibration by coupling it to a heavy mass. I used solid plastic feed with felt pads on my Mk3 to accomplish this.
- Isolate the combined printer mass from whatever it is sitting on by decoupling it. I used Sorbothane pads under the paver stone to accomplish this.
This reduces noise without requiring slow speeds, making both of you happy. I can barely hear my Mk3 mounted in a somewhat flimsy stereo cabinet even if I fall asleep on the couch next to it.

I had exactly the same issue when I moved to the Lack enclosure. Here's a link to a post I made yesterday about what I did to fix it. I went cheap on this and may do something nicer and more permanent one day. But this was literally a 5 minute fix and it was free.

Actually, I have already placed the printer on the floor, on 3 layers of some leftover-carpet with an acrylic plate (leftover from IKEA enclosure) and 25 kg of concrete to weigh it down. It helped A LOT! If only I could get the X-axis acceleration to slow down when repositioning/travelling.

Lets see how much the Lack enclosure will amplify the noise. If it does I will use a 40 kg concrete block as dampening.
I hope that I could find some gcode instructions to add to the beginning of the file, to slow down the movement of both the Y and the X axis.

Lack enclosure is hollow and make the noise even louder .
You could fill in the the lack enclosure to make it more solid, the table and legs are hollow.
A few flat stones could help under the printer.
