Compensation message….??

peirof

Hi,

This morning I changed the Kapton tape that I have on the bed. I have calibrated and tried to compensate … But, I received this error:

[[language]]
G29 Error G29 No valid grid defined for bed probing

The grid in config.g has a diameter 150 and spacing of 20.mm. The same used Monday.

Some idea?

i think i have it….

Too much points... i have erased heightmap.csv.... and seems work.

What is the point limit with Duet can work?

in this limit, the previous heightmap influences? seems yes

dc42

The Duet WiFi and Duet Ethernet allow up to 441 grid probe points. Did you upgrade the firmware since Monday? Height map files generated using 1.18 and earlier firmware do not work on 1.19 and later firmware.
