Ok. Im prepared to run 3 DC motors with 3 encoders.
Ive got problem with Maslow standard shield, especially with pinout schematics.
After i get this pinout i will prepare very dangerous files that will contain “Fat” DIY version of maslow shield.
Take a look at the system.cpp from the firmware. The type of shield it detected and the pins assigned accordingly. Line 98-227. You will need to figure how your shield will be recognized, or change the file.
Ring is made from very soft steel 12 mm.
I was planing to make somthing like this:
But I went in shop they had metal bender. 8$ for material with bending to ring (it must be soft steel, otherwise it will tear and act like spring).
Then i drilled 4mm holes in places where CNC ring have mounting points.
I don’t have money to buy cnc ring
I made few tweaks in my maslow 1.2 shield schema. Added more GND Pins and 1 more 5V out pin.
I’ve got problem. Every motor test fails. They wont even move(or I’m blind).
Im using A58SW-555B motors 1:290 27RPM witch buildin encoders.
I will try again tomorrow because today, only think ive done is to run GC on old laptop
I run GC on linux witch succes, but still every motor test fails.
I created test programs to set mill plate in middle of board using arduino, so H bridges works fine and moves plate w/o problem.
My bet is that encoder is connected badly. I rotated encoder witch finger and get message that Error Message that Sled is not Keeping Up
Help me understand that.
Look at the shematics of my DIY version. There is no connection for external power supply, this connection is placed on board that carry H bridges.
Soo, what i should correct
Shall i add Transoptor separation or somthing?
What is the procedure of motor testing?
Moment… shall i calibrate 1st?
Lets consider all options
I can power arduino mega from power supply and use Mega with ESP8266 if power is the case. I can optically separate USB for TTL communication and use 12V 5amps from power supply to run whole shield+Arduino.
I can power arduino witch 12V via power plug and it still goes through regulator, will I get better result?
It look like default shield works as power shield for arduino. My shield is doing this only for motor controlls, encoders that hangs on long cables dont get much power.
