Excessive heating might also be caused if the worm
mesh was too tight or if the worm lube had problems, like overheated/running
out of the worm, or if the worm drive assembly was dry of lube for some
other reason. Or if a lot of grit had made it into the worm drive
Do you have some kind of charger attached to your
65Ah battery while you are using it to power your
If you didn't restore the gears precisely to their previous
position, you will have to re-do your PEM curve.
What are you using for a power supply?
What is the current voltage going into your servo controller?
A voltage over 15V could cause more warming of the servo chassis than
usual. As could a big imbalance of the RA axis.
Ok it's funny that the tolerance has become so less , whereas the Dec
spur gear can be rotated freely , the RA can do so for half a turn on either
side , loosening a wee bit further causes a play , in fact the gear box
actually moves a tiny bit when reversing east west direction at 1200x . I've
left it at a point where there is no play in gear box and able to turn the
spur gear freely for half a turn . Let me test tonight to see if it heats up .
Question should the mother board show no increase in temperature at all ? Or
is it ok to be just warm ?
Thanks Peter !!
Will do that
Open the motor box side cover and rotate the large spur gear to make
sure it's not tight. If it's tight, re-mesh the worm gears and double
check the spur gears. I would load and balance the mount first before
checking and re-meshing the gears.
Today I kept my scope out in balcony , at
1200 speed both axes were sounding very laboured ; changed to 600 and
worked better but DEC was stopping every 10 seconds while slewing RA did
not behave that way . I had done pempro last night so wanted to check
again , for some reason un related lodestar would disconnect every 10
seconds , I changed ports , re started computer and changed laptop also ,
same problem . I accidentally put my hand on my astrophysics main control
box and found it strangely warm ( nearly hot ) I've disconnected every
thing now and re connecting . I checked by 65 ah battery and it shows 13
Pls guide me why this mother board of the mount appears so warm
