Remove the warped bow in heat bed  

RE: Remove the warped bow in heat bed

I followed these steps and this is what my Prusa XL looks like. I also felt like I had a warped bed. Looks like over 1mm delta.

We're currently looking into a similar problem with prusa at the moment with our own XL.
One thing I've discovered is a way to measure the bed as a mesh via probing

• Attach a USB-C cable from the printer to a PC
• Install / Download Printrun and use it to open up a serial console connection to the printer
• Run the following G code

G29
G29
G29 T0

For some reason sometimes I have to run G29 more than once, but it should probe the bed
The G29 T0 will then output some text you can copy and paste which lists the mesh level points

After that you then need to reformat the text a bit so it will work with the below visualiser
Basically re-order the lines so it's from 0 to 35 instead of 35 to 0
Remove " |", Remove any blank lines etc
Generally get it to look like the demo text in the below web page, then paste it in and visualise it
