Marko, we have lift-off. This is odd but good. While I couldn’t get Artisan to control
the Hottop, I went ahead and started a roast with the Hottop’s built-in program while
Artisan was connected. It started cooling because it was still hot from a previous roast,
and like I always do, I pulled out the chaff tray to speed cooling (along with the chute
cover and filter). Well, it seems that Hottop has added a new “safety” feature, because
when I pulled out the tray it went into cooling mode for a minute, then shut off. When I
turned it back on, Artisan was reading the sensors! So I started a roast with Artisan, and
it is working again. I assume it will continue to work through the roast, but wanted to
report this now because I don’t want you wasting time trying to find a solution when it
has started working again. I’m happy to help track down the issue, though, if you like.

Well, I got a new control board and installed it. Now the Hottop works correctly with its
built-in program, but Artisan still can’t connect to it. I’ve tried each option offered
for the port to connect to, but I think that is where the issue is. The option that seems
most sensible is:
Hm. Strange. You should see a difference on opening this popup while having the roaster
connected vs. having the roaster disconnected. That popup requests the list of USB serial
devices from the system on each click thus does a refresh of its content. The one extra
entry you should see while having the roaster connect is the correct one.
If you do not see a difference, you might have a driver issue. Note that on newer Mac OS
X version (I think from OS X 10.9 on) you should not install the FTDI driver separately as
that one would conflict with the one from Apple installed by default with the system.
But that doesn’t work, nor do any of the other choices.
Checking my /dev directory, I do not find cu.usbserial-DA01POGR. But I do find:
Also in this directory you should see more entries while the roaster is connected vs not
Has anyone gotten the new Artisan 1.2 to work on a Mac?
Works for me flawless!

worked. I think the control board may be bad, and have emailed Hottop support.

the new command to set up my Hottop, and now Artisan cannot control it at all. The
environment readings show minus 1 or 10 or zero, as if it cannot see the Hottop at all.
I’m connected with the same USB cable I used last week (and since I’ve been using
Artisan), but did also test with a different cable and different USB-A to USB-C adapter. I
also verified that the Hottop works with its built-in program.
