@rechrtb Yes. I have all three machines open in different browser tabs on multiple computers.

@Phaedrux No ... That was not the version of the plug I've been messing with. That one went in fine.

It's always the little things :-p. Thanks for the assist.

Yesterday I made up new leads for the BL-Touch using shielded cable, and I routed the lead along the filament feed tube rather than through the print head harness.

All issues have cleared up on both machines. Gone a whole day without bending a pin!!!

Thanks for your time and assistance @droftarts & @Phaedrux

Have a couple more issues to clear up on these machines, but those will be different threads.

@oozeBot - Thank you!

@zemlin said in Height map Z=0 point and Zhome point:

I haven't studied things closely, but it seems that bed mapping may assume z=0 is at xy 0,0

No, it doesn't assume that. The reasons we recommend Z probing at bed centre to home Z are:

Most prints are close to the centre If the bed has a tilt, then the height errors will be more uniformly distributed about Z=0.

It doesn't matter where you put the bed origin. I find it convenient to put it at bed centre, because that makes my prints portable to all my printers if I use the same filament type and nozzle size.

If you home Z and then immediately run mesh compensation (so that the temperature doesn't change significantly between the two operations), you should find that your height map has near zero error close to the XY point where you homed Z.

@Sevimuelli if you have a reading from the fan tacho then you can use the daemon.g file to monitor it.

@dc42 said in Struggling with PT1000 calibration:

If you are sure of the accuracy of those resistors, then RRF is working as it should. Either your PT1000 sensor is inaccurate, or your thermocouple sensor is inaccurate, or you have not succeeded in getting those two sensors at exactly the same temperature.

I have far more faith in the accuracy of the resistors than the accuracy of the thermocouple readout. The 2000 ohm is a pair of 1K .01% resistors in series. The 1096 is a 1K and 100 ohm resistor - but I sorted through a number of 5% resistors to find a pair that added up to 1096. Checking these with a good Fluke digital meter. I have a couple more Slice PT1000 sensors on the way. If they are in line with the other, I won't sweat it. Having them consistent across several machines is the goal.

The Duet Wifi board has been replaced with an Ethernet board, and the machine is now on a separate network that will not be accessible from the public wifi or publicly accessible computers.

Thanks.

@tinchus no- that’s not z-banding.. that’s me opening the chambers doors multiple times during the print. We utilize a belt driven z-axis which glides on smooth rods.

@phaedrux
Good call - Homing has an A1. Will change that. Thanks.

update: Editing the M588 command in the homeall and homez files resolved the issue. Thanks.

I really appreciate all the help.
I changed the can lines per @DIY-O-Sphere to

M950 F1 C"fan2" Q500 ; create fan 2 on pin fan2 and set its frequency M106 P1 S1 H1 T40 ; set fan 2 value. Thermostatic control is turned on

Functioning properly and not showing up on the dashboard slider.
The Z-Probe on this machine is accelerometer-based and that's a little flaky, but doesn't seem to be software related.

Up and running now, so 'til next time ...

Curious if those running liquid cooling notice any coolant level drop?
I'm running about a 120mm radiator and the pump tank is only about the size of a small drinking glass.
I've noticed a drop in level but no indication of any leaks anywhere.
Using radiator coolant.

I only cool the hotend and have been very happy with the results.
As an upside, on the titan aqua clone I have the pancake stepper runs with no apparent heat rise even at full amps rating current.

The rest of the motors don't get hot enough to worry about as it's not a heated enclosure, but it certainly couldn't hurt to cool them as the coolant temp I'm getting (only a few degrees over ambient) certainly indicates the system would handle it.

@3dML Good catch. I added that P1 trying to debug another issue and forgot it was there.

The warning is normal. Just letting you know what it thinks a runaway power temp might reach.

With some help from the forum here I got one of my machines running 3.2 Beta4?

No change in the stuttering. Tried 566 P1, that doesn't have an impact either.

Update - found the 3.2.beta4.1, but since it was mentioned that anything after 3.2 would have the improved processing, not going to duplicate the tests unless you think it's worthwhile.

Just an FYI to, perhaps, close this out. When I upgraded my machines to V3 firmware I tried enabling both extruder thermocouples. Both sensors came up without issue. I don't expect this to be related to firmware, but it was stable for quite some time. I've had other issues/adventures on the thermcouple front, but not related to this issue.

@rayman said in Raise3D N2 with Duet Wifi:

Hello! I have a N2+ that I converted to a Duet 2 Wifi as well but am having difficulty with the configuration. Any chance you could share what you setup or give me some tips? One of my main problems is a reversing axis.

Do you mean an axis is running backwards, or the direction reversing? You can reverse an axis with the S parameter on the M569 command. If it's changing direction when it shouldn't be, that's probably a wiring issue that not all leads are properly connected.

Here is my current config.g. I have a BL-Touch as the Z-stop and bed meshing which is wired like this: https://forum.duet3d.com/topic/7972/bl-touch-install-success
I run the Bondtech extruder and have removed all of the second extruder bits to reduce weight as I only run one material.

I replaced the thermocouples in the hot-end with E3D thermisters. I added a PT100 temp sensor to the bed.

Thank you. I'll give that sequence a go - although upgrading my second printer to a Duet may take priority.
