Just got the robot running. Running AR2 software. Able to jog all motors forward and back. Went to Auto Calibrate and this didn't look right. So decided to Calibrate each axis independently. J3, J5, J6 work correctly. J1,J2,J4 do not. They go forward then back a little, if I try to calibrate again it moves forward then back a little. Eventually I need to manually rest the position it moves forward more than back. Not sure what to check first?
I can’t find a source for the part(s) on pp. 286 of the assembly manual. The brass fittings with orange colored push-ins shown. Any pointers would be appreciated.
That sounds like the connection for the limit switch ground is possibly not made and floating voltage may be causing the arduino to see a positive signal. I would double check that each limit switch provides the arduino -5v when not made and + 5v when made. If you continue to have issues on this please email me a video of the calibration so I can see exactly how it is behaving. thank you. info@anninrobotics.com
Connected Mulitmeter and found the following:
NC switches 1,2,4 are open and should be closed
NO switches 1,2 will not close when toggled
6 switches, 12 outputs: 7 working, 5 are not.
Just tested all the mounted switches, all working correctly.
Removed wire harness and Project box, need to test all the connects on the bench.
Thank You for pointing me in the right direction. Need a couple days, and will report back.
Thank you for the update, please let me know what else you find.
I have a same problem with all of switches, but all wires is correct. Question is about -5V DC. Now I have 0V on my multimeter when switches is not made, and it's logically follows from electric schematic, where NC contacts connects to arduino GND. I suspect it is a root of the problem. I read the scheme wrong?
Oh, my understanding of therminology is wrong.
Anyway issue is relevant. All axis calibrate in same way.
