Multiple beds/chambers... bug?

soare0

I noticed some raised eyebrows here and there, when some users wanted multiple heaters, programmable, showing in DWC and Panel Due.

Still, this is a valid and important issue: one may need multiple items like those, or alike.

Yesterday I tried to use a water chiller, programmable, for on my 6XD/3HC printer.

It did not succed, because of many understanding issues, and meantime I gave up on this. Instead, I tried again today, with succes in setting a second chamber, for a filament dryer, a working one, I mean. So, if interested, can parse starting with POST 4. POST1 is, most of it, junk, but I let it so, if anyone wants to read it.

Finally, it seems I encountered some nasty BUG, even if I managed to make the filament dryer work... somehow.

@soare0 Sorry, no direct help but please can you edit your post to put the config file sections into code blocks? On my phone the button to add a code block is </> and it mades two sets of triple dashes appear. It will make it much easier to read.

This is what it appears like:

@DocTrucker Thanks for suggestion, it was welcomed, as I was asking myself about this... thing.

After some (more) reading and trying, I experimented with two possibilities:

Assigning the heater for filament box to T0 (in fact it is for it). Also, I took care to have sensor, output, etc, on the same board. In fact, I think all T0 is on that extension board
Making a separate heated chamber

Both seems to work, at first, but I like the 2nd better, and this is actual in (below) config.g.
Most of the problems, were due to coding errors, and insufficient understanding of the ”tool” concept.

Interesting, if one uses heated chamber in Cura, parameters will be sent to slot 0. chamber, wich is ok - I was not so sure it will work, as I have not checked the output from Cura.

One thing though, the chamber (main chamber, slot 0, that is) will be heated the last (one would think that its heating it would be needed to be start first), but in fact, it is not quite so... at all. Most probably there is a setting for heating order. For now, it is bed/nozzle/chamber, I still need to check where too look for.

Chambers shows ok in DWC:

Also they are showing ok in Panel Due.

Tomorrow we will connect PTCs, and do a test.

@soare0 Starting testing the filament dryer, I connected the PTCs, and ... start testing.

In DWC, all is ok. One can programm filament roll chamber, and it works well.

One can see that the chamber started heating, and all is ok.

HOWEVER, there seems to be a problem with Panel Due (I mean, maybe not with it, but with my 6XD, but it is shown there).

When setting active temperature for SLOT1 chamber, that is filament chamber, wich is the left one in the image, the settings will transfer to SLOT0 chamber, wich is the right one, the printing chamber.

In image 1 one can see setting the active temperature for chamber 1, and in image 2, one can see... the unexpected result: the setting is transferred to chamber 0, wich, well... starts heating!

Please understand: It is unlikely to have a coding problem here, in my .g files, as it works from DWC, at least this is my understanding of the system, now.

bug?

@soare0 Yes, it was a bug in 3.4.6.
I updated all the boards to 3.5.0/1 rc2, and for now, all works.

Thanks for all.
