Hi. Ordered kit and baraki valve. Now looking what jumpers to set for cytron MD12S but I’m confused little bit.
I understand there is on H bridge with MA and MB outputs. There is no two cytrons. So coils are in series between MA and MB motor outputs. This wiring ends up shorting half pwm to ground? If cytron has no connection to ground then still is it needed to have pressure switch ground connected to between two coils?
Which Cytron do you really have?
Which AIO PCB do you have (jumpers on that?)
I do not understand what you mean by shorting PWM to gnd, A side from cytron feeds one coil, and B side feed other Coil, which is reason both coils must have gnd at one connector.
On my AIO std V4.5 it is written on the board where jumpers go, but you also find info on documentation Wiki. (click on Assembling the board and you get pictures of jumpers)
I saw second picture on page Assembling the board | AgOpenGPS Documentation but I don’t see those jumpers on v4.5 Standard Boards/TeensyModules/AIO Standard v4/PCB Build/AIO v4.5 Std/assembled_pcb_JLCPCB.png at main · AgOpenGPS-Official/Boards · GitHub
I understand that there is no need to flashing of Cytron MD13S so I try to imagine how it works and what jumpers I need to set.
On upper picture does breaking happen? Or these valve don’t need push-pull and work OK with other side shorted? I would connect like lower picture but swap direction of one coil
Imagine this: MA positive output (variable by AOG) to steer one direction, while at same time MB is not used ( even though it could be gnd, and in this case gnd at both spools connectors mean no power use) and visa versa for MB positive output
No jumper needed here.
Only jumper to select which type of pressure sensor is in use.
