Motor Drive

[DemonicOmelette]

I'm sure you will all be sick of answering my questions very soon, so I better get them all in...

I've just hooked up the motor drive that came with my Skywatcher 130pm. I've hooked the spring up as I think it should be, but when the motor tries to drive, it "hops" on the gear. It works fine going backwards, only forwards I have this problem.. It works fine if I push the motor up into the gear and then tighted the twisty bit, but of course then I can't disengage the clutch without loosening it again.

Am I doing something wrong? Presumably I have it the right way around, with the motor UNDER the big gear, and the spring pulling the drive gear UP to it..?

heres how mine is set up

[DemonicOmelette]

Yup, that's the same as mine. How tight do you attach it? Does it not hop out of gear?

[Ghost66]

the spring is tight on there never had any probs with it

[DemonicOmelette]

Hmm. I can't figure it out. How tight do you clamp the motor to the shaft thingy? Do you tighten your RA?

[Ghost66]

maybe the t bar is to tight. needs to be holding the motor so it can move onto the cogs. apart from that is all i know.

[DemonicOmelette]

Hmm, nope, still no good. Thanks for your help, but we still haven't got it! If the spring were stronger, it would hold... I might bodge it with some elastic band or something...

Solved: Sorta. I've undone removed the big cog, and slid the spring onto the shaft it was on, then replaced the big cog. Pretty much means the motor drive is permanent, but puts the spring under more tension, and at a better angle to pull the motor up. All in all a bit of a silly system, isn't it?
