@dc42 said in Using chamber temp within a macro:

@medicusdkfzP

Is it possible to use the global parameter "chamber temperature" - I didn't find it in the object model - within a macro?

You can use the chamber temperature in a macro as @OwenD says.

And is it also possible to use only one slider to control the pwm of 3 fans?

Is there any reason why you can't connect the three fans in parallel and connect them to a single output on the Duet?

Yes, you are right… One of the 24V fans needs 80 mA. Three of them in parallel are under the limit of 800 mA.

The macro is working. Thank you very much!

This is my homez.g... I mentioned G31 for a better understanding. I guess, the trigger point of the probe will be set to the z-parameter in G31. In my case to 0 or to an offset...

@medicusdkfz said in M204 with square corner velocity like in Klipper?:

SET_VELOCITY_LIMIT ACCEL=7000 ACCEL_TO_DECEL=7000 SQUARE_CORNER_VELOCITY=8

Can you explain to those unfamiliar with Klipper what that command configures?

@medicusdkfz Historically I had my sensors floating "inline" like your pictures show, and I also battled these spurious faults and exaggerated min/max values. At some point I finally took the time to design housings/brackets to positively affix the monitors to a rigid structure (extruder, carriage, chassis, etc) and the faults disappeared. I am guessing it had something to do with twisting of the filament/ptfe tube, and/or lash in the filament conveyance path. It seems like however small the error was, eventually it would stack up and release at just the wrong time to trigger a fault.

It's often the little things that make life difficult: My extruder didn't make a sound on the 1LC and, as is always the case, you first check the crimp connections, the cables, the correct connections, the configuration - and everything several times. One is almost inclined to rebuild everything again, then one reads the last of countless articles and realizes that it was only a small parameter... Like above with the fan.

Kind regards, Pierre

@phaedrux I actually updated to 3.2.2 today and so far it's fixed the issue I was seeing.

THANK YOU! I changed G30 Z-9999 to G30 and now it's working. First layer looks good and consistent - even at bigger areas. No need of a microswitch. The SuperPINDA is highly accurate. But I had to reduce my poll rate:

M558 K0 P5 C"io4.in" H5 F80 T18000 A5 S0.01 ; set Z probe type to switch and the dive height + speeds (S-1 -> nimmt die Anzahl des A-Parameters zum Testen), B1 (schaltet heaters aus) G31 P500 X0 Y25 Z0.575 ; (0.475 mm hot, black PEI-sheet) set Z probe trigger value, inductive probe offset and trigger height (Papiertest, G92 Z0 setzen und anschliessend G30 S-1/G1 Z5 mehrfach wiederholen -> Höhe = Offset ; wenn die korrigierten Z-Babysteps positiv sind (z.B. 0.080 mm), dann werden sie vom Z-Parameter unter G31 aufsummiert!

For the sake of completeness:

I reduced in M558 param H5 to H3 and S0.01 to 0.03 and now it works.

@Veti said in Need help with mesh bed levelling:

G30 S-2

you only need that if you are calibrating your probe initially

That's G30 S-1

@medicusdkfz I don't think you'd usually ever need G30 S-2

https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_G30_Single_Z_Probe

G30 ; Probe the bed at the current XY position. When the probe is triggered, set the Z coordinate to the probe trigger height.
G30 S-1 ; Probe the bed at the current XY position. When the probe is triggered, do not adjust the Z coordinate, just report the machine height at which the probe was triggered.
G30 S-2 ; Probe the bed at the current XY position. When the probe is triggered, adjust the Z offset of the current tool to make the current position Z=0.
G30 S-3 ; Probe the bed and set the Z probe trigger height to the height it stopped at (supported in RRF 2.03 and later)

I would use the filament selection feature of DWC for that.

I have also used dummy fans as text variables (the name) which display in the fan section of DWC. I use macros to set the fan name.

If you have a Z probe then you can use that for Z homing if you wish, and then you don't need the Z microswitch at all. See https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Homing_Z.

I've found them already. It's the same link...

Thank you,
Pierre

Just checking.

Thanks, I'll mark this as solved.

The web configurator lets you define the extruder motors and heaters and then assign them to tools and edit the offsets.
