LIS3DSH orientation on a Delta printer

[dc42]

@Velvia this is probably caused by the CS wire picking up noise from other wires. Here are some suggestions:

1. Drive CS from one of the spi.cs pins on the daughter board connector, if one of them is free, because they have greater drive strength.
2. Change the cabling so that the CS wire does not run close to any other wires except for Vcc and Gnd.

@dc42 You were right. It works now. Split the CS cable and ran it far away from everything else. Was able to make measurements now. Thanks!

Are there shielded ribbon cables available?

Yes, however I have used unshielded ribbon cable successfully with these boards. If you use a 10-way ribbon cable and IDC connector to plug into the daughter board connector, then spi.cs1 can be used for CS because it is on the outside of the cable and the adjacent wire is ground.

I'm planning on using a shielded guitar wire for the cs wire when i wire mine up.

@dc42 I was able to get three readings, but now every time I try to get readings, it freezes the mainboard and it restarts.

@Velvia which firmware version are you using?

[Velvia]

@dc42 3.4.1

Update to 3.4.5?

[Velvia]

@Phaedrux Thanks. I do that by running "M997 S0:1", right? Been a while

@Phaedrux Thank you for the help. Now I run as many times as I want, even with the Input Shaping plugin. No more crashes!
