I would like to have auto-scaling of temperatures graph - would make tracking lower temps easier.

Perhaps it would be also nice to have dual-scale - left scale for tools (usually higher range), right scale to heatbed/chamber (usualy lower range).

@phaedrux I bought it from Hobbystore, around IX.2020

I have 2 of them, and can swap to check if this issue is still there.
In fact I have no idea why I did not do that already.

I will test 2 cases:

• use second one and second wiring, just adjust the config to completly eliminate path from the board to sensor and sensor itself
• swap the seonsors only, so the wiring will be the same.

It would be nice to have recursive delete for non empty directories.

If state.gpOut[3].pwm==0
	M42 P3 S1
else state.gpOut[3].pwm==1
	M42 P3 S0

condition in else is obsolete, and more "elegant" way is

If state.gpOut[3].pwm != 0
	M42 P3 S0
else
	M42 P3 S1

I think that viable solution would be to use NFC tags and a spool holder with reader. With new spool just put a nfc sticker (can be bought easily) and set a filament length when spool used for a first time.

Then each time spool in put on spoolholder read the tag, and update legth when print finished/tool change/ etc

Easy to implement - nfc readers are available with many intercaes, tags can be bought without problems.

Probing twice the same point?

@dom I think latest paneldue will not work properly with 2.05.1 firmware. Update Duet firmware to 3.2.2

@wieman01 Y range is limited only from one side. Y=0 coordinates can be reached by bltouch - it just moves nozzle to position Y=36, and then proble is at Y=0.

But.. if nozzle can go only to Y=350, then probe can reach only points with Y <= 350-36.

So M557 would have Y range Y0:314, as any higher Y is out of reach of probe tip.

IMO panel due is just fine. HD display with milions of colors? This is not a multimedia player. It is just not needed.

And... not everyone is using RPi. I find convinient to power on my printer and have instant start, and not to worry about powering it down just by a switch instead of dealing with linux boot-up/power down sequence just to keep filesystem right.

But this is just my opinion.

I have a chamber heater (H3) with temperature sensor (T4) in it, and second temperature sensor in chamber (T3).
Setting chambe rtemperature works fine, and everything seems working OK except one thing - limiting heater element temperature.

Heater temperature should not go higher than 120 *C, so I set temperature monitoring like this:

M143 H3 S100 P0 T3
M143 H3 S120 P1 T4 A2

so the chamber max temp is 100*C, and heater should be "temporairly disabled" when it reaches 120 *C.
Obviously heater gets disabled by second monitor when max temp reached, not sure how to re-enable it again. I expected that it will be enabled again when it's temperature drop, but that is not the case.

Any advice how to handle that?

@phaedrux But it also recognizes direction. So I would expect measured movement would have to correlate with extruder movement in terms of movement direction, but this seems not to be the case.

@petrkroupa So this is the oposite to what is on the photo from documentation. Hmm... that would mean it works both ways.

@norder I saw that photo, but is there any difference from which side filament comes in?

What is the right orientation of MFM? There are no markings to which side filament needs to be feeded.
At least I could not find any information about that.

@oliof Basically any internally temperature compensated probe will do (with proper output type obviously). I did some research once and Prusa's was cheapest one that works with 5V power supply (original prusa board back then, not required for duet) and is temp. compensated and in 8mm diameter).

Personally, I would use SuperPINDA which is temperature compensated internally. Not much more money, a lot less headache Been there, did that.

I uploaded to Duet3 standalone, and board no longer starts. I think I need to find some recovery from this state.
Update from 3.4 -> 3.4.1RC1

Edit. Restored 3.4 with bossa, flashed 3.4.1rc1 again - no issues this time. So some kind of a glitch
