Z axis only moves down when homing

Hi all.

Got the ooznest 1500 x 1500 last week.

Have a little issue here lol. When homing all the axis’, the z will only move down about 3-4mm. IKt won’t go up to the limit switch! Is there something that I have pressed to do this strange homing?

M120 G91 G1 Z0.5 F360000 G90 M121

Error: G0/G1: target position outside machine limits

Many thanks

Joe

Hi all. Had a look at the limit switchs on the laptop and the Z axis always says ‘triggered’! I have found out that the limit switch on the this axis had some dust in it! Cleaned it and it works just fine!

Cheers

Same issue here, the switch seemed permanently closed, so I clicked it quite a few times and it works again. Will buy some spares to have handy if this is a sensitive weak point. Maybe there are some dust proof alternative switches? Any ideas for alternatives, Ooznest engineering team?
