John, I have tested the Axis One circuits and I am getting a short between pins 1 and 2, and 3 and 4 on the board. That translates to 1 and 3, and 2 and 4 on the motor, given the way I have wired the

Khalid, The cables are a standard assembly of 4 wires leading from a 6 hole plug (which came with the motors) soldered to wires leading to an off the shelf plug matching the Axis socket. The solder jo

Khalid, I've ordered replacement LV8729s from Germany, should be here in a couple of weeks. Both axes displayed the same behaviour, even when I changed from one set of drivers to another. By changing

Absolutely, it suggests the problem is somewhere between the main board and the motor and that leaves the drivers, wiring and the motors themselves. I'll try the reset and also move the wires around a

One set were plugged into a board that got fried. The other set was unused, I'm sure. Gerry

I have two sets of LV8729. Both sets fail to reverse. They were bought about 6 months apart from separate sources. Gerry

Other drivers as in alternative models, or same type replacements? Gerry

The board is plugged in and powered (It was actually set to tracking). The probes are touching the driver side pins, not the PCB beneath. Gerry

Howard, Yes, I'm getting a voltage change when I select a change of direction in the control box for Axis 1. It goes from 3.3 to 0 and back again when I press W, then E. But the motor does not change

Some good ideas there John. I've separately posted my Jumper settings. I'll start with the Serial Monitor commands, then substitute another program before moving on to the other tests.Gerry

I wonder if my Jumper settings for the motor drivers are correct? Here is a photo of my settings for the two LV8729 drivers on Axis 1 and Axis 2. Gerry

Here are my Axis Stepper Driver Config.h settings. Can they explain the fact that the motors will only turn in one direction? Gerry // AXIS1 RA/AZM // see https://onstep.groups.io/g/main/wiki/6-Config

Kevin, As you may see from my latest post I tried some spare LV8729s and it made no difference. But that doesn't rule out the probability I may have got duds! Gerry

1. I swapped the wiring for the two motors but both continued to drive one direction only, no reversal possible either in slewing mode or using the control in an attempt to "nudge" the motors in a rev

Mike, That's a very good point. However I'm using a FYSETC S6 V2 which requires very little soldering. At the same time I have been using a temporary bench testing connection between the driver and th

Khalid, I can actually watch the motor sprocket turn and the gear wheel turns with it. I don't believe backlash is involved. I think there is something in the configuration settings, or in the motor i

I should add I am using FYSETC S6 V2 with LV8729 drivers. Gerry

While bench testing using Sky Planetarium I cannot "nudge" my motors in reverse using the Control function (Connections/Control). They will simply continue in the same direction as in a slew or a trac

My GPS does not appear to function and I note Khalid's comment here about defining the GPS serial port as #define TIME_LOCATION_SOURCE GPS #define SERIAL_GPS Serial3 #define SERIAL_GPS_BAUD 9600 And w

I have not experienced an update fail but continue to be unable to flash my latest FYSETC S6 Board despite having paid forensic attention to all the neccessary files and settings. Cannot help wonderin
