Thx for all the help, it now works correctly. Roxy I've also incorporated your Enhanced G29 command, much nicer than the original (e.g. no retracting between probing), KUDOS! Now i just need to get my 1st layer to stick on my buildtak (tried changing the offset). When i look at the nozzle, i can clearly see the compensation, its kinda a oscillating alot. Well well i try to level my bed as much as possible with help of the topological map and try again

Thx again!!!!
