Hi Guys
First off I would say that I don't usually ask questions in forums I like to figure it out for myself. But at this point I'm totally stumped My experience has been for 2 years with the Printrbot Simple metal so I know M212 well Clearly need to forget that now with G31.
I fitted a inductive sensor to my D-Bot build followed the instructions to get it configured & working so far so good. Ive levelled the bed manually & carried out all the relevant steps to get mesh working & a height map built. However when I print my first layer is not quite squished enough, I baby step down 3 clicks & all is good. So m understanding is that I need to adjust the Z offset in the G31 command however it seems that what ever i adjust it to makes absolutely no difference. When I send a G31 T it does show the value stored in the config file but as i said seems to physically do nothing. Ive tried not use mesh & going for normal probing, added & removed G28 from my Simplify Start scripts and about a million other things including re-leveling the bed & doing the whole procedure 4 times now but still I'm stuck. My config file is below would appreciate any help you guys can give as Im at my wits end now
Thanks
