Bed Levelling struggles  

Bed Levelling struggles

Hi All,

I've been struggling to print wide prints, so I decided to get OctoPrint setup, do the nyloc mod and use PrusaMeshMap to get everything nice and level.

Before doing the nyloc mod I created this map, which appears to be well outside the 0.05 recommended goal. This matched my experience of printing, because the outside of larger objects wasn't sticking to the bed.

After doing the nyloc mod I'm having some problems. I turned on the 7x7 bed levelling and whenever the head gets to the far right, points 47 & 49 it will measure multiple times and sometimes goes and does the Z-axis something or other. If I put the textured sheet on, this tends not to happen. I'm guessing the sheet is adding some rigidity to the bed...

What I really need some help with is to understand how to fix this. When I look at the map I get now, I see low points between screws.... How am I meant to get those areas level....

Any advice would be much appreciated.

Thanks

Ben
