Gen2.1.14 (ex2.16) (Razor) #42
Comments
@RoboDurden thank you for writing up this issue. Since this board is mostly mapped out I decided to flash the MCU with the 2-16 code changes. I was digging around and it turns out that I can't find the motors for this board. To be honest, I think I salvaged the bearings from the motors for another project. Anyway, the motors should be somewhat universal so I tried hooking up a different motor but I was not able to find a hall sensor combination that would drive the motor. The motor I tested happened to be 300 watts and this 2.16 board layout was originally paired with a 25v battery. I had my Constant Current power supply set to 25v and 1.0 Amps. I increated the voltage to 32 and the amps to 2.0 and still didn't have any success when going through the 6 hall sensor combinations. I may try a lower wattage motor tomorrow. By the way, the Red, Green, and Orange LEDs blink and change if I move the motor manually. I checked the MOSFETS for shorts and found none. Any Ideas? I was not able to get the arduino serial monitor to display any output from the board. It is just showing garbage. I am not sure what I am doing wrong. On another note, I have another board layout that I have started to trace that has the same MCU as this one. I will open another issue and include some photos at sometime this weekend. Thank you so much for your help! I am really learning a lot! |
By the way, the photo above with the traces, the part that is in shadow is GND on the other side of the board. I forgot to turn off that layer when I exported the image from gimp. I would like to upload the Gimp file to the Schematics folder so that the work I did tracing might be helpful to someone else and they can take advantage of the layers. The file of over 40MB though :-( |
I must keep the repo as small as possible so downloading the complete repo is possible for everyone.. Is the motor at least vibrating and you only do not find a permutation that works smoothly ? Garbage on UART usually means wrong baud rate. All motors are compatible I think. Not the sockets. |
Thanks to @andyshmandy
This board seems to have only one dual opAmp so no overall current dc. And only 2 low-side phase currents (not needed for this gen2.x firmware but needed for the SimpleFOC firmware).
