Strange noise from X-axis after upgrading 3.3 -> 3.4.0-b6

[Falkia]

After upgrading to 3.4.0-b6 there is strange noise from the X-axis when jogging from position 0.0 (Its just when the movement starts, and it looks like the axis jumps).
If I jog X increment 10.0mm:

• from 0.0 -> 10.0 (noise)
• from 10.0 -> 0.0 (OK)
• from 0.0 -> -10.0 (noise)
• from -10.0 -> 0.0 (OK)
• from -5.0 -> +5.0 (OK)
• from +5.0 -> -5.0 (OK)

Delta with Duet 2 WiFi. Smart effector but its not wired so the parameters for M665 are manually entered.

The macros I have for testing the machine (only move axis) does not work so good anymore. I think steps are missing and a lot of hiccups is reported by M122

[Falkia]

Update: The problem is for Y axis also but only from -150.0 in any direction.

[Falkia]

Update 2:
Testing all other 3.4 beta versions and this problem occurs first with beta 4.

[Falkia]

Reading the change log for beta 4, there is a bug fix for step calculation for delta printers. Maybe that has something to do with this. Any clue @dc42 ?

[Falkia]

Update 3:
Changing the Delta Radius with M665 affect the position where the Y axis makes the noise. The position where the X axis makes the noise is still at 0.0.

[Falkia]

Made a firmware downgrade to 3.3 and now the printer is happy and so am I.

[Phaedrux]

Thanks for verifying that switching back to 3.3 resolves the issue.

[Falkia]

@phaedrux yes, but hopefully it will be fixed later on.
Thanks
Fredrik

[Falkia]

I can confirm that this is now fixed in 3.4-b7. Thanks @dc42
