PT100 reading 2000°

Thanks, the "Hardware error" is the message I was looking for. When that error occurs, the firmware currently doesn't allow any retries before raising an error. I'll change that.

Thanks DC, I look forward to giving it a try

Actually, I built the new version two days ago, but I have been too busy with the Duet WiFi to test it yet.

[Aflac]

Well that sounds like a good thing to be working on. But if you ever need help testing I can easily run whatever tests would help you.

[dc42]

If you want to try it, it's at https://dl.dropboxusercontent.com/u/193 ... rmware.bin. All I have done so far is load it on a printer and check I can home the axes. OTOH the Duet WiFi build f om the same source code has been working well today, although I haven't tested the RTD support in it.

If you get a temperature spike with this version, please look for a detailed error message again.

Have a print running with that firmware right now, so fat so good.

[Aflac]

Well that print worked perfectly, I'll have to do a few longer ones to make sure that problem is gone, one negative result does not a trend make.

I had a problem with my water cooling loop on my computer and that slowed down my testing, but I got that fixed this morning and ask is good.

I've successful done a 1 hour print and a 3 hour print without the error, both prints I would occasionally get through with out the problem but never twice in a row.

I have a 7 hour print going right now, and if that works I'll throw a 12 hour one at it. If i can make it through ask that without an issue I'll be fairly confident it's solved.

I'll report back with results tomorrow....sooner if it fails

My printer has been running for nearly two days almost constantly and so far so good. Have not run in to any issues with that new firmware

Thanks for the feedback!

The candidate 1.13 release is now available at https://dl.dropboxusercontent.com/u/193 ... rmware.bin. As it is not quite the same as the previous version, there is a possibility that the problem might come back again, if the cause wasn't always the "hardware error" code.

[Aflac]

Well I tried a print with that firmware, I have not figured out yet what went wrong but 30 minutes into the print the printer shut down and I haven't been able to get it to turn back on.

The only known problem with 1.13 is that the thermostatic fan feature doesn't work correctly - it turns the fan on at only 50% PWM. That's fixed in the 1.13a version that I have just released.

So I just installed 1.13b onto my duet. I seem to get quick failure to heat, although since I has just using the paneldue, it wasn't very informative about that (I haven't really updated the paneldue, so if that's something fixed in a newer version, great). I'll get more diagnostic info to dump on you tomorrow david, but it seems like 1.13b is actually less stable with my PT100 than 1.12 was.

I'm getting some other annoying issues, like the printer seems to deselect the tool right when it starts printing. I think that adding a T0 right after the G10 should fix that, but the PT100 issue started popping up more once I added it.

The console window of PanelDue should show any error messages. If you are trying to heat the hot end to 260C or more then you will need a M143 command in config.g to increase the maximum allowed hot end temperature.
