Rotary Delta Robot 4 axis

I looked at the manual and it looks like your not connected to analog ref gnd should be pin 44. .

7i77 aout => pin 42 delta servo
7i77 gnd => pin 44 delta servo analog input signal gnd

You have it connected to 13

Also you can try with battery.

How is the 5V side on the 7i77 powered ?

His pictures show he is getting 5v from 5i25

Yes, I saw in page 58, as you mentioned GND is Delta's pin 44. But in page 40 it is "13" too. Even I will change pin "13" to "44".

You can also disconnect the wire for +-10v velocity control and use a 1.5 volt battery connected to the +-10 input of the drive, and that should tell you which side the problem is.
If it doesnt move then it is not Lcnc side unless the drive is not enabled.

I did not change jumper settings. But I am not sure Mesa 5i25's 5V is enough for my configuration.

Tomorrow I will try what returns mesaflash --device 5i25 --readmid command.

Thank you your fast answers.

If you want to supply external 5V, (I always do), then you have to change a jumper on the 5i25 and 7i77.

Hello bevins, I tried to drive servos with a 1.5 battery. And, it works. I am checking wiring. And I will try to measure drive outputs of 7i77.

Which jumpers I have to change on 5i25 and 7i77 ? I am just aware of W5 of 7i77. And nothing I found about 5i25.

W1, W2 on 5i25 5i25 manual page 2.

It comes default disabled. If your supplying 5v to the 7i77 via external power supply leave them disabled. If you want to supply 5v to the 7i77 from the computer you have to enable it through those jumpers but you need to set jumper on 7i77 also.

How can i set hal files ?
