It can be hard to determine what exactly causes tipping especially on natural or pulped Brazil. Have a close look at the black power profile line on Luke's screen shots above. This line will never be as smooth as my examples because of the probe difference. Even so Luke's power profile looks quite d...

This is good discussion as it will help people fine tune this method as its definitely never going to be automatic until one fine tunes a profile for their particular beans and environment. My guess would be a higher fan calibration will end up producing the higher temp readings particularly on the ...

Hi Luke, Thanks for the kind words. Looks like a typical fresh? Kenyan behaviour, they love to take off at the start. Definitely a bit quick on the first one! If you can get yellow around 2:00 - 2:15 and slowing down a bit before then so that it does not rush through the colour change this is ideal....

Thanks Darryl. A couple of other things that have come to mind: The "end by time ratio" is set to 1 meaning the roast automatically ends at set time regardless of temperature. I have been stopping a lot of roasts manually and find this more user friendly. The starting power for the roast i...

I believe these two profiles are my ultimate baseline / starting points for any style of roast, a culmination of everything I have done before. One initial caveat is that I am using a 3 mm sheathed probe in place of the stock bare thermocouple. The position is a little lower down in the roast chambe...

Hi Darryl, These were just exploratory roasts and the MET thing is a bit of a dead end BUT this did help generate further ideas about early roast development. I and a couple of other people have spent considerable time and greens testing many other things out culminating in what I think could be the...

Its reassuring to read not just me becasue the aftertaste on that cupping roast is something else!? I tried 3 very different greens and they all tasted the same which originally made me think there was something wrong with me, pays to have known good samples vac sealed in freezer. Worst case scenari...

Hi Howard,

The naturals more delicate outer layers may experience some high levels of development and you could play around with a more gentle pre heat.

These hot fast profiles are best consumed 3 to 5 days to appreciate any fruity floral aspects.

Cheers

Thanks for the reply Wayne I understand the reason for safety feature and if someone accidentally used a modified software / firmware it could cause fire used with stock probe.

Thank you for offer, I will reply more detail via email.

Cheers

No its the stock KL thermocouple which as Wayne answered my other question is a K type, I assume welded tip with PTFE cable because it has not melted no matter where i put it and the tip is super robust. If nothing changes i might try a 100mm flexible SS 3mm sheathed probe through original hole and ...
