Mini 5 and Z axis noisy in idle

tecno

Jogging is no problems but Z in idle is very noisy.
No problems with other board with 2209.

Any thougts what can generate this irritating noise

@tecno not sure, maybe the stepper mode spread cycle and also look at the current you are using for Z. The Duet 3 Mini 5+ is limited to 2A current for each driver. you could either be over or under delivering.

Never played with different modes, has been working OK

This how it sounds ! NOISY !

It looks like I have a busted Z motor on my Voron 0.1, this is the second motor giving up.

1st = noname Chinese
2nd= Stepper Online

Ordered a new one = LDO Motors from Lector in Estonia

@tecno 400mA seems pretty low for the motor current is that correct? You should also probably try running the motors in stealthchop rather than spreadcycle (at least the ones that are making a noise). See: M569 and the D parameter.

@gloomyandy

Stepperonline docs specify 400mA/Phase, yes it is a bit on the low side.

Will test with D parameter

@gloomyandy
D3 makes no difference
