@Phaedrux - Another note - I'll now do the Calibration for the PT1000 per:
https://docs.duet3d.com/en/User_manual/Connecting_hardware/Temperature_connecting_thermistors_PT1000

Puterpro - Out. Be well my distant friend.

@Phaedrux said in Extruder not showing Temps after upgrade:

And just on the off chance that something went wacky with all the firmware updates, you can re-apply the firmware entirely by uploading the 3.4.5 zip file to the sys folder.

https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.5/Duet2and3Firmware-3.4.5.zip

Upload the file itself, don't extract first.

That's what I started with, and I know to load the zip. I'll re-download just in case and try it if you haven't any thoughts about the heater test.

EDIT: I edited "e0temp" to "ctemp" and moved Thermistor to there, same message - HE is "Active" and Temp is "n/a". I'll try reloading the firmware as above and let you know.

BINGO! I suspected corrupted s/w but didn't question the Github download I'd done.
Came right up but temp was wrong so I guess I'd used a PT1000 so I changed "pt1000" B4092 and we have:

Yea! I'll move it back to E0 so I don't go "Huh??!?" six months from now. Ha!
Thanks so much, you're a Prince.

@Phaedrux Interesting thought! Wish I'd thought of it, LOL Here's the results (E0 disconnected)

@Phaedrux said in Extruder not showing Temps after upgrade:

If you're on firmware and DWC 3.4.5 just stay there. No need to jump around firmwares now.
Noted. Wanted to be sure I got a good load and json matched my changes for future uploads to Configurator.

If you copy and pasted the config sample for the heaters I posted, the config should be correct.
I agree. But it didn't work ... Also - Heater and Thermistor wired to either E0 or E1 makes no change.

Can you post your config.g as it currently is?

Sure:

And finally, how bout a photo of the wiring on the board?
OK:

Can you check continuity of the thermistor cabling?

Mentioned twice above. Digital Multimeter reads both heater and Thermistor at normal values. I also said I'd substituted a new, good, (knowing that's NOT the same thing LOL) Thermistor for testing, still gives "Active" and "n/a" for temp. Note: this machine has been running perfectly for months under 2.03, only change is the Firmware. Not dealing with some recent hardware change. FYI - I know you deal with lots of wiring & bad parts issues, but I'm an Electronics Tech for a looong time. Not bragging, just info. Wirings messy but functional. Thanks for your help with this!! LOL

@Phaedrux Well Hello old Friend! Very long time since we spoke, hope all's well in your world.

No joy. I had moved to E1 for both heater and Thermistor, so for this code I moved them back to E0.
Same thing. I get "Active" and "n/a" as above. DMM reads both as normal values.

I grabbed a brand new Thermistor and tried it for a test, same thing.
I'm guessing corrupt software somehow.
I misunderstood in my 1st steps that Configurator would ALSO grab the latest files (Firmware and DWC) and include that in the zip, so I handled the config files & DWC as separate uploads from the Firmware. I get now that was wrong.

My upgrade path was: 2.04 / DWC Equally old > Backup sys to zip > Update DWC only to 3.1.1 > updated to 3.0 Firmware > load updated 3.0 zip from Configurator > Load 3.4.5 from Configurator zip for all.
BUT for the last step I unzipped the config.g from the zip, edited manually and verified line by line in Notepad++ 'Compare mode' to my old config.g, then replaced it back into the zip, THEN uploaded 3.4.5 to the Maestro.

I realize now that was a lot of unneeded work and the Comparator handles it all. Duh. (OCD creeps out LOL)
Here's current:

You think I should run Configurator directly from the json in sys and try again with a new load? EDIT: Did "edit via config tool" and re-ran Configurator, fixed a few values (matching current config.g above except a few minor things). I chose "Semitec 104NT" and SET values using it's defaults. No change. END EDIT

Or go back to 3.3? Or wipe and try again?
Note I went 2.04 > 3.0 > 3.4.5 not 2.04 > 3.0 > 3.3 > 3.4.5.

I'm in your worthy hands.

@dc42 Yes Sir! BTW - I moved the Heater and the Thermistor back to E1 as it's been fine there for years. ALSO - I realized I had the old config-override.g with the old values so I renamed it config-override.g.old in case it was the culprit. No joy.

@jay_s_uk K doing it ...

Where's it put the output? I entered in console and nothing happened I could see

Long time user of Maestro, finally decided to get off 2.03.

Ran through RRF configurator, mapped my values, created a zip and did a side by side update of my config.g to map in all values and fix errors. Saved changed file back into the RRF zip.
Read tons of guides and after 1 false start managed to get from 2.03 to 3.0 to 3.4.5, including DWC up to 3.4.5 as well. I killed all the little bugs and typos and all's well except the Extruder.
I've a CR-10S (highly modded) running a E3D Gold HE with a genuine E3D Semitec 104NT. All was working fine under 2.03
It was attached as E1 heater and Themistor connected to Themistor 2 (E1). During Configuration I accidentally specified a pt1000 (had it on a Dragon HE which died). Realized my mistake and manually reconfig'd to the Semitec 104NT.
Doesn't read temps. Heater shows Active and will select temps (doesn't heat of course) Temp shows "Current - n/a"
Checked thermistor with a DMM, reads 101KΩ. Tried moving them both to E0 but same results!
HALP! What the heck am I missing??

That did the trick! Thx! So much to absorb ...

Just trying to setup new config for upgrade to 3.0 prior to 3.1, and I started fresh, no JSON loaded.

When I get to the Endstops page, "Unmodulated or Smart IR Probe" is selected and BLTouch is greyed out.
I'm configuring a Maestro, Cartesian.

I checked I/O Mapping and it says under Z-Probe:

Input Pin = zprobe.in
Modulation Pin = zprobe.mod
PWM Control Channel (BLTouch only) = (not assigned) <-- This does not allow another choice, the drop down opens but won't accept a click on zprobe.mod (or inverted).

I can set it up manually after I'm done, but what's up with it not allowing a BLTouch??

Just make sure it's A beer ... LOL!

Glad to hear you're chasing the axis first. I always advise people make sure the mechanicals are right before messing with the settings. Can't believe how many times I've seen someone wrestling with settings when the problem is a loose widget ... You obviously get it. I guess having that many printers will do that!

Have fun!

@deckingman
Thx! @Phaedrux was quicker on the keys! Appreciate the help, as usual my friend.
2mm here I come. now to find some that they don't want $50 USD for a pair.

I have to deal with WAF.

I think I found someone on AliExpress that will cut down a 550mm to 515 and appears to have nice quality, I just have to wait until Thanksgiving or so ... LOL.

@Phaedrux said in Advice on upgrading from 8mm Lead to 2mm Lead T8 screws:

And I doubt anyone is going to want to use 0.2875mm layer heights.

HA! You don't know what I'm planning! {Insert evil chuckle}

That's about what I came away with from my research. My 310x310mm bed isn't that heavy, especially with the load on two motors. Thx.

A total minefield for a newbie

I LOL'd at this one. I setup mine almost two years ago and thought that. After a lot of work and mind numbing reading of posts and articles (and a HEALTHY dose of help on here!) I finally mastered the beast.

Here we are, a while down the road, and I made some upgrades to my machine and the house of cards came down. The old adage "If you don't use it you lose it" kicked in and again I found myself banging my head on the desk as I struggled relearn AND to grasp the changes that occurred since last time!

I'm now back in it (mostly) and it occurs to me that I might try my hand at writing a beginners guide aimed at the total noob. I'm fairly good at explaining things once I grasp them, my biggest hurtle is that I tend to long winded. Nature of the beast {SIGH}.

There are lots of guides out there, many of them excellent, but I'm thinking sorta a "Guide to the Guides" with some simple explanation of the major terms thrown in since that's often the main sticking point when starting a new field of learning.

The guides don't always define their terms up front, so the beginner gets lost in the terms rather than the concepts being explained. The old "Well, I'm at the end of the page and I'm more confused then when I started" thing.

I'm sure I'd be asking a lot of Q's of the old hands if I do it to ensure I don't send someone off a cliff, LOL! (I can hear the groans now )

Hang in Bob, it'll start coming together. Good luck!

@deckingman said in Advice on upgrading from 8mm Lead to 2mm Lead T8 screws:

@PuterPro I published my own thoughts .... https://somei3deas.wordpress.com/2017/01/31/z-axis-lead-screws/

Thx, I'll read that.

I use 1mm lead screws (single start, 1mm pitch) but 2mm would also be fine. I bought mine from China via Amazon.

Read it. Nice post, I knew most from my research (like 1 start vs 4) but you made some points clearer. BTW - I forgot the name of your blog, but as I was reading I grabbed my COLD coffee then started laughing.

So, 2mm vs 1mm. Any real difference in choice? Obviously the 1mm give a touch more accuracy. I've been looking for 2mm lead but I'm open here.

I'm running the little motors Creality used, but being there's two of 'em I imagine I'll have no trouble driving either rod choice. I'm currently limiting them to 900ma. here's my motors section:

M350 X16 Y16 Z16:16 E16 I1                         ; configure microstepping with interpolation
M92 X80.00 Y80.00 Z400.00 E412.00                  ; set steps per mm
M566 X900.00 Y900.00 Z12.00 E120.00                ; set maximum instantaneous speed changes (mm/min)
M203 X12000.00 Y12000.00 Z600.00 E1200.00          ; set maximum speeds (mm/min)
M201 X500.00 Y250.00 Z16.60 E166.00                ; set accelerations (mm/s^2)
M906 X1000 Y1000 Z900 E800 I30                     ; set motor currents (mA) and motor idle factor in per cent

And for reference, here's the (VERY hard to find) motor info:

So I'm running about 60%. I am running the Maestro right around 27v .

You see any issues here?

And you can hold that weight with zero motor holding current, whereas the weight of a heavy bed acting on the steep helix angle of a 4 start thread might cause the bed to drop when the motors are deactivated.

This has always been a problem for the CR-10S series. Something I liked about the Duet is easily telling it to hold idle to reduce this. Not currently a problem for me but nice that it lessens the drop potential.

For those who have upgraded to 2mm Lead screws, have you seen much difference and what was your source for the screws?

I've got what started life as a CR-10S running on a Maestro. I've read about this upgrade in several places including this one from @Phaedrux :

https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+5:+Upgrades/54?lang=en#s208

The one thing that strikes me is that with 2mm lead it's evenly divisible for any layer height, no more being restricted to certain layer settings.

My rods are the stock Creality and they were both slightly bent and pretty rough. I've cleaned them up and straightened to "pretty good" but still would like to dump 'em.

How much impact have those who have this noticed or is this just another hole for money?

One problem I face is the rods on my CR-10S are 515mm, an odd size. Although I can cut down larger and re-bevel it's a pain.

I've found two local sources on Amazon, one after contacting the manufacturer on AliExpress, and a bunch of other on Ali too, of varying quality.

Here's the Amazon ones for anyone else doing this:
https://smile.amazon.com/dp/B07QFL6D46 <- Expensive but looks good quality (close up pics on AliExpress, here: https://www.aliexpress.com/item/32921211173.html)

EDIT:

Other Amazon source: https://smile.amazon.com/dp/B0851F5P7Q <- This is HALF the price, but no reviews so ... Of course in this day of fake reviews, that may be a blessing! Also they would have to be cut 550mm not 515). <- This is confusingly described and is actually a 8mm Lead.

Like anyone doing upgrades I'd love to get polished, straight rods for $2 each ... LOL. But I have found paying for quality usually pays off. Still if anyone has a good source for quality rods for little outlay, I'd love it.

Thoughts and advice welcome!

@PuterPro My dude, tone is difficult even in real life. Sorry if I come across as belligerent sometimes. I'm only intending on being a tiny bit belligerent.

Especially for Engineer / Tech types who tend towards awkwardness in all social situations! LOL

Peace out!

We do need to put a fork in this whole thing, a few comments for clarity -

@deckingman said in Baby Stepping.. can it, or can it not be permanent?:

Woah, hold on my friend. There is a world of difference between adding something that makes life slightly easier than editing one line of gcode, and restoring basic printer functionality to the firmware, which are the things that I'd like to see implemented.

I could not agree more! I absolutely agree that the things you're pushing for should have priority over such a silly thing as Baby steps being optionally persistent. I was just commenting on it being dismissed out of hand by someone who doesn't use it, and offering a case scenario where I could see it's validity ... if you get my drift. (And I AM drifty ... LOL!)

@bot said in Baby Stepping.. can it, or can it not be permanent?:

This request, beaten to death, is already achievable with the current behaviour .... add a line at the end of your config.g that runs a macro with M98 .... Done. It will save your magic sequence of babystepping settings to load every time you boot.

Thank you for getting I wasn't berating you, it's sometimes hard with just text and an emoji or two ...
THAT's a simple way to accomplish this, thanks for that, now we have a couple solutions. Personally I rarely use Baby Steps but I have found it handy at times.

@OwenD Hilarious!! Love it. And thanks for the solutions, I confess to a misread of your earlier posts ALSO being in humor. Working on my halo ...

@DeltaCon said in Baby Stepping.. can it, or can it not be permanent?:

It is certainly no dealbreaker for me. I did not invent the subject.

@ ALL - This sums up my involvement as well. I apologize for extending this so long when obviously there are multiple ways to solve this without changing the firmware. Many thanks to all that participated!!

@Phaedrux said in Its safe to move a Duet v2 to firmware 3.x:

for the average person.

HEY! WHO ARE YOU CALLING AVERAGE??!?

I've been lightly stroking my finger on the trigger, but assuming {AHEM} RC12 is the last ...

I guess I'll wait for the final release since I'm running fine now thanks to all the kind people here.
