X axis not working correctly
#23
Having trouble with DRO erratic display. Chinese linear scale display is fine.
Yuriys pcb assembled ok, checked all soldering (not a junior at soldering).
ensured correct order of wires to scale, B+, clock, data , ground.
tried reversing clock, data, chinese scales didnt like it.
Reseated cpu to ensure good contact with header. (would have preferred machine pin header).
Heartbeat ok. Probe LED off.
Bluetooth connection ok (after fitting 1000uF Cap across raw incoming supply rail).
All non connected axis are at zero - no issues. moved device, leads away from bench, turned off fluoro & all other disturbances.
despite erratics I could see no changes to x axis on the dro.
- do the inputs to the LM339's need small value caps on their inputs?
HELP!
Also, am i supposed to see probe On dro app? not sure what to expect..
hope U dont mind my saying that i am having a bit of trouble finding stuff on website - articles seem scattered everywhere.
