If you don't want the rough surface you can simply turn the build plate.

I have not been able to create a profile on Cura 5.2 using the meager instructions from Longer. Do you have any suggestions?

[@228vincent]

Where did you get the print file for the moon?

[@WhereNerdyisCool]

Mine, the manual leveling is way off Like, I literally unspin the wheels...the springs at feel expansion don't come close

[@lilqueeniescraftingismypassion]

I pray you can help I am not finding vids on homing issues with the lk4 pro I just bought any suggestions, Iv emailed the company and no response yet! What does homing issues mean and would you know how to fix. Thanks in advance.

[@BusterBeagle3D]

Hello. I’m sorry but this is not the LK4 Pro but the LK4X. They have different homing sensors. I would make sure there is a good connection to all of the limit switches first. Other then that I’m sorry but I’m not sure what you issue might be.

[@Gkitchens1]

So it’s been a year so you probably already figured all this out but if you are having hiking issues on the lk4 pro it’s probably one of your limiter switches is out of adjustment. The bed can get warped on the lk4 pro also.

Having issues with my Beagle V2 working with my LK4 X. Any suggestions?

[@BusterBeagle3D]

I don’t have a beagle V2 so it’s hard to tell. I would try resetting it to factory and try again, I use my original beagle cam with my LK5 Pro so it should work.

[@NickCentonze]

For some reason it's just not working from the app. The Web link controls it fine. Thanks for the reply though.
