Re: Wrench for electronics bracket
Hi Larry, You will probably find the cables to the RA and DEC motors will not reach the controller in the lower configuration. That is why mine is on the 12" column extension. Works fine there and has

Re: Gemini 2 Version 1 problem at power up
Thak you for the information. There is not a second input attached. I have bench tested the unit without the motors, so that is out. I too suspect and IC or the H bridge. I have not checked the ICs

Neil Do you have the 2nd 12V power out connector plugged in! ? If so remove this and power on. ?It could be an accessory on this line drawing too much current. ? Yes it has 2 fuses one for each

Re: PIC Servo firmware v3.1 vs v3.0?

Re: PIC Servo firmware v3.1 vs v3.0?
Ok. I was seeing reference to a higher torque fw on a old thread. Is that in the ¡°latest¡± v3.0? If so, it¡¯s interesting that didn¡¯t trigger a version change.

Re: PIC Servo firmware v3.1 vs v3.0?
For clarification, there¡¯s little difference between 3 and 3.1. Scott shipped version 3 of the servo firmware. 3.1 was a slightly later build (days) with a change to the means of communicating the
