Is anyone having an issue using Pronterface with the new Mini Alpha update? When I run G29, all I get are probe point values, no complete mesh.

Is anyone having an issue using Pronterface with the new Mini Alpha update? When I run G29, all I get are probe point values, no complete mesh.

 

Same

RE: Prusa Mini Silicone Bed Leveling Mod

I have the same problem. Has anyone managed to solve it?

RE:

Maybe G29 T after G29.

RE: Prusa Mini Silicone Bed Leveling Mod

Yes, "G29 T" works but I get a 6x6 grid instead of 4x4:

I have the latest Prusa Mini+ 5.1.0 software

"G29 T1" gives better 6x6 result view for further analysis:

RE: Prusa Mini Silicone Bed Leveling Mod

has anyone had issues with UBL since upgrading to 5.x? The calculated mesh values for the outer perimeter are off and causing my prints to not stick. I think I’m gonna go back to bilinear meshes 

RE: Prusa Mini Silicone Bed Leveling Mod

I‘m having issues with my first layer too. Is it possible to switch back without firmware downgrading?

RE: Prusa Mini Silicone Bed Leveling Mod

Hi all,

@rockytoptim, dindn‘t checked it 100 % but seems to be setup for MK3, is that correct? As the position of sensor is different, it might not work accurately on mini, just guessing. Anyone any experience with this?

Currently I am downgrading for leveling and upgrading back again. Sound annoying at first but is not that much effort and gives me the best results. I wrote a short guide here: https://forum.prusa3d.com/forum/postid/692974/

Cheap source for tubing - $5 shipped for 1 foot - https://www.ebay.com/sch/i.html?_nkw=silicone+vacuum+hose+3mm+id&_sop=15

RE: Prusa Mini Silicone Bed Leveling Mod

Even cheaper source of tubing. While taking my blood pressure with an arm cuff style BP monitor. I noticed the black tubing between the cuff and monitor was a silicone material. After checking the outside diameter, it matched all requirements needed for this Leveling Mode. After removing a short length for the mod, I found it worked and no harm to the Blood Pressure Monitor.
