new to me bot and I am sorting out the bugs.
got it all working but one quirk.
Every time I turn it off it resets the Bios and cmos. I’ve plugged in a new battery and verified voltage at the board pins in the board to connector.
Jumping the 2 pins with a keyboard plugged in I can get to the Bios and reset it to get the the pendant working. robot runs fantastic, pendant works great, but if I shut it off, I need to go through the bios all over again to get it to boot correctly as if the batter was dead.
I’ve done this with multiple new battery’s to verify
jump pins, boot up, f2-load defaults. use mouse with pendant to shutdown, jump pins, boot up, f1 and change settings to get touchscreen working. save bios and operate bot. shut down… back to square one. sometimes if i boot the bot up right after shutting down (within seconds) it will load up perfectly. not all the time. but give it 30 seconds or more after shutdown and its defiantly back to sq. 1.
any insights?
its only got 50 hours on it, everything looks brand new. board level ive only checked the pin out where the battery plug is to verify voltage on the board.
im half tempted to remove the board and put it under the microscope looking for bad solder/look for any irregularity’s. im not great at this kinda thing but have got lucky spotting some failing solder before
Never mind, flipped the battery leads in the plug and it worked fine, plug was setup with wrong polarity.
ill leave this up to hopefully help someone some day
