I put this in ‘taking care of the bullet r1’ because I don’t think it’s the machines fault. I think I need to know how to service thermal probe.
See my two videos here: https://photos.app.goo.gl/xBy6ft9Y79AnmiEj6
Last two roasts, the IBTS raises normally, and steadily but part of the way through the roast my thermal sensor starts going crazy, and the rate of rise is then going wonky, but the IBTS just trudges along normally as though nothing is up.
I think it may be right around the time that I turn up the drum speed, or turn up the fan that it happens. However don’t be fooled, its not like the wonkiness is just that the beans started to cool and there is a slight dip, its that suddenly I went from RoR of like 10 to -90 then less than a second later its showing +80 then -45…
I think maybe the sensor is not reading right, maybe the cable is crimped or getting feedback. Something.
Note the roast curves are not showing up in roast.world either.
I have updated the latest version of roasttime but when this is happening the machine is also showing the crazy fluctuations. Also the roaster is on the beta firmware that has been published for a while because I have the new fan that requires it.
