I think your X axis is loose in some way. G29 probes alternate lines in opposite X directions. What I think is happening is that when the belt pulls the X carriage, it tilts the carriage, changing the nozzle height. When the belt pulls the carriage the other way, it tilts the carriage the other way.

I haven't used the Dyze so i can't really help. I know some users had problems with the Dyze thermistor because of its very high resistance at room temperature, but AFAIR they brought out a PT100 alternative. Maybe they offer PT1000 as well now.

@dc42 i have the PT100 sensor with MAX31865 board, is working great thou i tend to get a clog here and there....thanks I took care of the bed issue, i retighten the X carriage and belt and it seems to have gone away
