@T3P3Tony said in Duet Mini 5+ Temp1 failure?:

@SpeedyDad can you ground that?

I'd basically have to grind the powder coating off the cold side and run a ground wire to it.

@SpeedyDad what is the coldside you are using?

It is basically a Revo Six

@Phaedrux Will do. How do I ground an E3D Revo? On the Hemera XS on my other printer, I grounded it to a mounting screw on the extruder body. There are no screws on the Revo. Grind off part of the anodizing and sandwich a ground wire in the mount?

When and where did you purchase the Mini 5?

November 29 2024 from Filastruder.

I have a relatively new Mini 5+. It successfully completed a print a couple days ago but yesterday, I switched it on and started a print when, after a couple minutes, I noticed that the hotend was reading 320. I thought it was a thermal runaway so i shut it off and figured I'd look in to it today. When I say shut it off, I turned off power at the power strip.
Today I turned it on and the temp for the hotend was reading 264. I thought that was odd so I put my finger near the hotend and felt no heat. It was stole cold. Figured the thermistor (e3D Revo) had gone bad so I plugged another known good one in and it read the same thing. Turned off the machine and unplugged the thermistor completely and, when I turned the machine back on, the temp read 64. It should have said 2000. I then turned it off and plugged the hotend thermistor in to Temp2 and reassigned it in the config file. Now, it shows the proper temp. Board port failure? I'm afraid to start a print in case the thermistor caused the failure. Thoughts?

@jay_s_uk Yup, that was it. Thanks! It's odd. I can't recall ever changing that but it is possible.

@jay_s_uk OK, that makes sense. I'll give that a try.

@jay_s_uk How would that affect it if it is only affecting X and Y. I have not changed Z jerk settings and this issue just started happening. Here it is anyways.

Now that i think about it, I've been having some issues with printing height. It prints fine but in the center of the bed, it prints too low and the print peels up. This started happening about the same time as the stutter seemed to start. Could my height map file be corrupted or maybe the SD card?

I've had a problem crop up lately and I'm at a loss to determine what it is. During X and Y moves, the machine randomly stutters briefly then starts moving again. The faster the speed, the more it pauses. Z axis doesn't do this and neither does E. The machine is a 400x400x400 Voron 2.4. It is running DWC 3.4.6. It's not a slicer issue as I've tried it in both Simplify3D and Orcaslicer. The odd thing is that it doesn't do it at all when I command a homeall and the head moves to home X and Y but will have a slight stutter when moving to probe Z (Bltouch)

More bits of data, it doesn't do it at all until I run mesh compensation test.. During these "stutters" there is no perceptible voltage drop and the MCU is running between 36 and 40c. The stepper motors are cool to the touch.

Stalling?

Thoughts?

OK, Got it. I figured it was a "I'm on a Mac" thing. Instead of just downloading the file, I right-click on the download link and did a "save As". It downloaded it with a longer name and that zip file worked fine.

@droftarts
I am running DWC 3.4.6 according to the printer. And, I'm on a Mac if that make a difference.

@droftarts Actually, Mine says:
; Configuration file for Duet 3 Mini 5+ (firmware version 3.3)
; executed by the firmware on start-up
;
; generated by RepRapFirmware Configuration Tool v3.4.1 on Sat Aug 17 2024 21:55:35 GMT-0700 (Mountain Standard Time)

M115 says 3.4.0

@droftarts Ah. The Duet docs say DWC 3.4 so I assumed I was OK. I was trying to avoid having to upgrade to 3.5.3 to avoid having to ask update my Toolboard and paneldue and, I imagine, there would be changes to the config file too.

I have downloaded the Input Shaping Plugin and left it as a .zip file. The instructions say to do an Upload & Start of the .zip file but when I do, I get "Only a single file can be uploaded & started". This is a Duet Mini 5+. When I check the config file, it shows firmware version 3.3.0 but when I do an M115, it says firmware 3.4.0. Am I doing something wrong here or....?

@Phaedrux Yup. This printer in its previous life was a dual Z setup so I am familiar with that but I will have to wrap my head around setting M671 up for 4 Z axis.

@soare0 OK, looking forward from the back. Kind of what I thought. I wired it front looking back and thought "that can't be correct"

Sorry for this rudimentary question.

In the documentation for configuring 4 driver Z axis, it references rear left, rear right, etc. Is this looking forward from the back of the machine or looking back from the front?

I know it really doesn't make a difference in normal use but for 4 corner leveling using my BLTouch, it definitely needs to be correct.

Thanks

I actually figured out my problem. I have a couple crimping tools I use for RC stuff (servo wires, etc). Nice ratcheting ones. When I would crimp the wire, the wire would break where the insulation was crimped. After looking at it, I found the long legs of the connector itself that are supposed to crimp the wire insulation was curling in on itself and cutting the wire. My remedy was to cut the little legs shorter. No problems now.
