Something wrong in that Z LEVELING TUTORIAL https://www.youtube.com/watch?v=L9URtv2LqKc

edited October 2015 in Extruder & Bed
Hi,
I wonder why in this turorial : they use G32 and G29.
In another post, you say that there is no need to use G29 because G32 is more efficient (http://forum.repetier.com/discussion/713/g29-crash-my-delta#latest).

Finally, what's the difference between G32 and G29 ?

Second question :
On my delta printer, G32 works fine but when I do :
- G32
- Mapping with Reptetier Host
- G28 (not in the video but necessary ?)
- G29
like in this tutorial, The G29 doesn't Works. The upper-left and upper-right probe points are out my bed (It probes a 7 by 7 matrix instead of 3 points with G32). I red in a post that normally, G32 and G29 should probe the same points.
Can you explain this strange behaviour ?
How can I change the coordonates of probed points with G29 ? Is it necessary ?

Version of Repetier firmware : 0.92.5

Thank you for your answers !

  • G29 dehaves differently if you have distorion correction compiled or not. If it is compiled in, it will measure the height map like in the video. If not it will measure 3 points and compute  average height instead of rotation correction. This is what you see I think.
