Is there a way to tell DWC to refresh file list using curl?

Not AFAIK, but @chrishamm might know otherwise.

Hey - will state.previoustool be persistent through power cycle/M999?
It would be nice if there could be a condition check on homing to make sure that the previous tool is re-docked before attempting a home, to prevent damage to tool (especially from inattentive tinkerers)

The only things that persist across a restart are data stored in config-override.g when you run M500, and the software reset data.

For tool changers I suggest using microswitches to detect when tools are docked, or a microswitch to detect when a tool is loaded.

@dc42 Talking about tool changes... is it possible also to have a nexttool object? That would make it possible to already preheat the next tool to be used.

A facility to read the GCode stream ahead so that tools can be preheated and filament mixes changed in advanced is planned for Duet 3. There probably isn't enough RAM to fit it in Duet 2.

I have Duet 2 Wifi and i have same problem with fan rpm showing random number's. So i will try this update to see is will be same or it will dissape. Thanks @dc42.

A few questions:

Do we still have a line length limit? Object model fetches such as 'heat.heaters[tools[state.currentTool].heaters[0]].current' burn through characters quite quickly.

How are line numbers counted when I get a syntax error? The line number given by RRF does not match the error location. Should it be file-linenumber, or are things like empty lines and comment lines skipped?

About the maximum stack depth: how deep is it? It is tempting to split code to separate macros, just like you would normally do with functions. This does increase nesting depth though.

I do not really want to bother you guys with this yet since I have to carefully check the hotend heating before complaining, but I see 'maximum excursion' heater faults when I do not expect them, such as soon after programming a lower temperature for an active heater. Did anything change in RC2 regarding heater fault detection?

Yes, 160 characters, not counting leading spaces/tabs.

It should be line number within the file, with 1 being the first line. If you think it doesn't match, please submit a simple example that reproduces the issue. The column number (if given) is generally the number of the character after the item that caused the problem.

5 at present, but it will be increased to 7 in the next release or RC.

Not intentionally. Again, if you can reproduce a problem, please post a demo file.

With heater 1/tool 0 active and heater 2/tool 1 standby, executing a 'G10 P1 S250 R200' at the console triggers an 'Error: Heating fault on heater 2, temperature excursion exceeded 15.0°C' after a few seconds.

'M109 T1 S200' works. 'G10 P0 S250 R200' works. Machine homed or not does not change the behaviour.

If I execute a T1 so T0 is put in standby and T1 is made active, the behaviour reverses. 'G10 P0 S250 R200' triggers an error, 'G10 P1 S250 R200' works as expected.

For this test I made sure there were no active M570 commands in the config.

I confirm this was an unintended change in 3.01-RC2. Please can you check that the new binary at https://www.dropbox.com/sh/3azy1njy3ayjsbp/AACquxr2m00eV568RZg5QG5wa?dl=0 corrects it. This binary also has the maximum stack depth increased to 7.

I can confirm that the issue is resolved.
Thanks for the exceptionally quick response, once again!

I will check the error line numbers later, with this firmware.

I haven't changed the line numbering in this build, so I expect the issue is unchanged. Please supply a test file to reproduce it.

Is it actually possible to define more than one probe?

I tried M558 K1 for G38.x and M585 but it always responds only for my Zprobe

Currently it's possible to define more than one probe but not to switch between them.

smoki3

@dc42 I don't understand?

; Z-Probe

M558 K0 P5 C"^!zprobe.in" H3 F180 T25000	   	; Z probe connected to Z endstop input
G31 K0 X0 Y0 Z0.17 P500          	               	; Set Z probe offset + naher ran - weiter weg

; Tool Probe
M558 K1 P5 C"!e0stop" H5 F120 T3000  		  	; Tool probe connected to Z endstop input
G31 K1 X0 Y0 Z0 P500          	               	; Set Z probe offset + naher ran - weiter weg

I defined this one. If I report the probe status with G31 K0 or K1 it always only responds for K0. If I try to use it K1 in G38.2 P1 or in M585 P1 it only react when K0 is trigged and not for K1

I see the problem, which is that there is only one Z probe input filter. So only one Z probe can be type 1,2,3 or 5. Defining two type 8 Z probes works for me. I will add a note to the M558 description.

Running 3.01-RC2 on the expansion board, for me at least, results in none of the motor drivers working.
I have had to roll back to 3.0-RC2 to get them to work and to be able to print.

Hello @dc42 why my fan rpm on duet web is wrong.it's show number between 25000 and 32000 on my noctua fan which has 100% open PWM 1700RPM.
i upgrade my DUET2 Wifi with: Duet2CombinedIAP and Duet2CombinedFirmware

Please help

Is it a 4-wire fan, and have you connected it as recommended for 4-wire fans? Was it giving the correct RPM before you upgraded the firmware?

If so then my guess is that the tacho input is picking up noise from the PWM input, or from stepper motor cables in the same wiring bundle.

matej1006

@dc42 Yes i have noctua 4 wire pwm i have blue wire to fan7 on duex and tacho with 1n4148 connected to pb6 on duex
and previus version also didn't work same problem random number between 25000 and 30000
and now after i send home posittion then show's that strange nubmer for PWM before that is around 1700 RPM
