JHCCoffee The grouphead lights stay green/yellow/orange on some occasions and red on others, even though the front power button is not depressed and I have exited the v1.42.1 app. Why do the lights remain on? Why the colour variation?
Mm good question! I’m not sure why they stay on. This doesn’t sound normal. The GHC will change colour depending on the machine state at the time, but there should never be a solid ring of colour at any point which persists for more than a split second. One for Shin or John on Basecamp.
In the Mimoja Caffee skin, touching the Sleep button does not seem to do anything. Why?
I’m sorry but I don’t use Mimoja, have you gone through the Mimoja page in the manual?
What do each of the colors displayed on the grouphead signify?
As above, they are triggered by the state of your machine. The colours mean the following:
Yellow - this happens when the machine is first booting up. The DE1 GHC will slowly illuminate yellow as it tests all internal systems. Once they are all confirmed to be working perfectly, the yellow light will fill the entire 360’ circle on the GHC and then disappear.
Red - this shows the progress of the group head getting up to temperature. Once it is up to whichever temperature you have set for the profile you are using at this moment in time it will fill the circle and disappear, just as the yellow light does above.
Blue - when running low on water the GHC displays a really nice wavy/flickery blue pattern on the GHC, which indicated the reservoir needs to be refilled.
Blue and green - when pulling a shot, the GHC will show the current pressure and flow rate via green and blue lights on the GHC itself. It uses a standard clock face to demonstrate values, ie if the pressure was at six bar and the flow was at 2ml per second the green and blue lights would illuminate to show the equivalent of ten past six. You can also drag the lights to your chosen flow rate by moving your finger around the GHC whilst the shot is in progress as you would a paddle.
Purple - flashes momentarily to confirm a profile change (ie saving a new prove or adjusting a previous one) and also to confirm a new profile has been chosen.
That should be all of them, but if you’re getting something different let me know.
In the Mimosa skin, when I pull a shot, I see two separate line graphs. I need to understand what each line color and solid vs dashed line, in each graph, means.
In this skin, I see 4 buttons on the bottom, for various preset profiles. How do I set up these buttons with specific profiles?
For both of these queries, again, I’m afraid I don’t use Mimoja as my skin of choice and so suggest you check out the manual for further info.
How can I permanently delete profiles? I don’t mean whether they show or not. I mean how do I permanently delete them?
You can delete the source files on the tablet if you like, they are listed under the ‘profiles’ folder. Easier to just hide them though, particularly as your tastes may change depending on the beans you are using, or if a profile gets altered or updated by the author.
