Before first power up question
« on: July 11, 2019, 16:33:23 »
Hi folks,

I'm just about ready to power up my AstroEQ for the first time and am wondering if there's anything I should be aware of before I do. Also, assuming I've done things right and nothing smokes, then what?

Thanks.

Okay, so I had my wife go over my work and she approved.

Powered it up and was able to update/configure.

Had downloaded the wrong piece of EQMOD. Now have something called EQASCOM, and once I configured the com port, AstroEQ now brings up EQMOD.

When I click on N, the stepper motor kicks like one step. When I click multiple times the motor moves but it is rough, like hitting with a hammer.

***update***
The motors were wired incorrectly. I thought it was 1A/2A and 1B/2B but it's actually 1A/1B and 2A/2B.

I noticed every time I open AstroEQ it leaves a lot of stuff blank even after it reads from the device (motor step angle, gear ratios, etc.).

***update2***
I guess the config stuff doesn't matter because I have things running with Stellarium on the bench.

Don't worry about fields being blank after a read. The gear ratio information is not stored in the EEPROM. Instead the converted values are (aVal, sVal, etc.). Unfortunately there is no way of getting back to the entered values from converted ones.

You can of course save your configuration to file and reload it later.

The axis reverse settings can be changed without pressing the calculation buttons, so you can change those from just the recalled converted values.

Thanks Tom!

I'm a bit excited. I have the system running on the bench currently with Stellarium.

As for the blank fields, I have saved things to a config file so no worries. One thing I am puzzled/curious about and that's gear ratio - I'm using 2:1 (30T15T). Obviously, I can change this to 3:1, 4:1, etc. What determines what's best?

Your gear ratio setting needs to be the actual one 2:1 any other value will mean the mount slewing and tracking incorrectly.

Hi Tom.

I was thinking the gears themselves rather than the values plugged into the configuration utility.

I just got my "final" gears: 15T and 40T.
