Fried EQ6?

[pvelez (Pete)]

I have been wrestling with guiding on my EQ6 for some weeks now. At first I put it down to the new QSI and not being able to bring it to focus. So I switched back to the guidescope. Still, the errors kept on coming - a slow drift in the Y axis.

Having exhausted all different settings I could think of, I decided to try and move the mount using the move button in Maxim - and the problem became apparent.

For ome reason, I can't move the mount in the Y axis - but only in 1 direction. It willingly responds to positive moves, but not negative. I thought it was backlash that needed to run out so I set the move instruction to the maximum - 50 seconds - thinking that eventually it would move. After about 8 attempts, I gave up.

Now here's the odd thing - I can move the mount in any direction with the hand controller - I am using EQMOD with a wireless Logitech controller. Guiding is via the ST-4 port.

So I suspect the issue is with the ST-4 cable, an internal conflict in EQMOD or Maxim or I have fried some of the electronics in the mount itself. I have checked that I haven't turned off any mount movement tabs in Maxim.

I'll have a test (indoors) today to see if I have the same problem with pulse guiding.

Has anyone else had this issue?

At least (at this stage) it doesn't look like pilot error - a small consolation.

Under maxim guiding click on settings and make sure all the Y axis boxes are ticked.
I'm wondering how it can calibrate if one axis isn't working?

Hi Robin

it is odd isn't it.

I checked the settings and they are all ticked.

I have noticed before that when calibrating, the reference star moved back and forward in the x-axis but only one way in the y-axis. In other words, the star move throughout the calibration phase through the L, but steadfastly refused to move in the last stage. However, because the y-axis changed when calibrating in x (not because the y axis moved, only because the star moved diagonally when doing the x-axis calibrating), Maxim sees that the target star has moved more than 5 pixels in both x and y, it is happy that its done its calibration routine.

By the way, I can calibrate with PHD - but then not guide with it. The guiding is lousy with PHD - go figure!

Fire up the pulse guiding then. You can dump the guider cable then anyway. I've just packed all my guide cables away in a zip lock bag, they really aren't needed anymore. In maxim you select telescope instead of guide relays not ascom as you'd expect.

Tried that too

Seems very odd - would move the mount in 3 out of 4 directions with both Ascom and telescope setting

Ohhh nooo. Doesn't sound right at all, especially if the handset buttons work. Do the move buttons in eqmod work?

Tried pulse guiding tonight - this time without the ST-4 cable plugged in and set to Telescope

Rock solid - best guiding in months

I am a goose! Thanks for your tips Robin. I needed the extra data this evening for an SAO project due tomorrow

Don't fry your EQ6 in oil...dry frying tastes a lot better

Add some paprika and it's a done deal

Better than goose or BBQ'ed robin

I had a similar problem using my ST-4.
It turned out to be a problem with the wiring in the 15 pin connector on the ST-4.
