Hi Tom

Here are some pics of the back of the pcb.

Yes, I did connect power first then USB.

I have just tried running the firmware update but after about 10 minutes it eventually got to the upload failed screen.

Sorted out the duff joint betweenC13 & C14 and away she goes, loaded the EQ5 config to the controller successfully.  My mount is actually a GPDX but I believe the gear ratios are the same.  Thanks for the help I shall now sort out the stepper motor cables and mounting gear.  Regards

Could you check C13 and C14 first, there appears to be a solder short between them which would stop the crystal oscillating.

Can't see anythign visibly wrong with the board, other than one end of R14 isn't soldered, but that wouldn't cause an issue as it is just the power LED.

I'll post out another ATMega to you tomorrow. It will be interesting to know if it is a faulty chip.

Kind Regards,
Tom.

Hello Again,
I have checked the board for dry joints and reflowed 3 but to no avail. Attached are two pictures, the solder side of the PCB and a screen script of the failed update prcess.  Hopefully they will be useful to you!  Thanks & Regards

John
