Robe fixture tilt feels stiff...?

[jona1984]

I've noticed the tilt movement of one of our Robe 575 spots to be quite stiff, compared to the pan movement which feels normal and moves more easily.

 

I've had the shell off and blown it out with a compressor but I'm unsure as to what could cause this. I thought about trying to spray some lubricant into the tilt arm mechanism but I worried that this might not be a sensible idea so thought I'd ask you guys! :-)

 

Anybody have any experience with this?

try using a bit of indenitured alcahol (as it evaporates after flushing) on the motor bearings at the rear of the tilt stepper motor. keep the head moving whilst appliying the liquid, you should find the motor frees up after a while.

Cool, thanks mate! Will give that a go.

If you unplug the wireset to the motor(s) is it still really stiff? If it isn't your fault could actually lie in the wireset or stepper ic .

If it is then drop of medium oil into the front and back bearings on the motor(s). keep motor(s) unplugged and move head back and forth to loosen (keeping the motor unplugged protects the drivers)

you are almost there for a new motor

 

with oil you will some extra days of life

 

good luck with that
