Yes, that probably works nicely. I will implement that.

(Still, I could use variables well from time to time, and persistence would be nice too. Isn't is possible to add a few user locations to the object model, or is the object model readonly from g-code anyway?)

Now I only have to find out why that Scaffold stuff keeps plugging the heatbreak, even with very little retraction, cooling the inactive nozzle and moving a bit of the stuff each layer.

@dc42 Wanted to check on this also. Since you're looking into the filament sensor code, would it be possible to add an additional S parameter to M591 to monitor filament movement during all filament moves?

I finally got the macro working with following code:

; Source: https://forum.duet3d.com/topic/4202/homing-to-z-max-when-also-using-a-z-probe/19 ; Start g-code: G28, M98 P"0:/macros/Leveling/SetZ" ; run z fine tuning ; If the printer hasn't been homed, home it ;M291 P"checking homing status" R"Homing status" S1 ; Report status if !move.axes[0].homed || !move.axes[1].homed || !move.axes[2].homed ; Check if axis are not homed ;If axis are not homed, home axis echo "Axis are not homed, performing homing" M98 P"0:/sys/homeall.g" else ;If axis are already homed, home only the X and Y axis echo "axis are homed, re-homing x and Y" M98 P"0:/sys/homex.g" ; Run the Home X macro M98 P"0:/sys/homey.g" ; Run the Home Y macro ;G1 X100 Y100 H0 F1800 ; move to be centre slowly. ;End homeing check M291 P"Axis homed" R"Homing status" S1 ; Report status ;echo "start fine tuning z-level" G1 X100 Y100 H0 F1000 ; move to be centre slowly.

I changed and tested several different thing, but i think the trick that did it was removing the empty line between the end of the "If" block and the start of the "else" block.

Presumably your usage case does not require a shutdown or other more definite action in the event of a heater fault or you will have set the firmware to take such action above a certain threshold.

You could monitor a heater or sensor in daemon.g and use something like the following.
You have to create the file and put it in /sys
Note, this hasn't been checked for correct syntax etc.
It's just a general guide.

EDIT: Also you have to consider that this would resume any paused print if the temp was under the set value, regardless of why it was paused! You have to figure out how to differentiate the reason it was paused. Until we get variables that's a bit harder. You could maybe set a dummy fan value or something.

if {(heat.heaters[nnnn].current > 150) && (state.status = "printing")} M25 ; pause if {(heat.heaters[nnnn].current < 150) && (state.status = "paused")} M24 ; resume G4 S10 ; wait 10 seconds before checking again.

@npedro said in IR temperature Sensor and Conditional Programming:

I was thinking using an analog IR sensor.

If the sensor produces an analog output that you can scale or limit to 0-3.3V then you can use the LinearAnalog type of sensor in RRF. You could use the daemon.g file to read the sensor periodically, calculate the correction needed and use the M220 command to change the feed rate multiplier. Please note, M220 doesn't affect moves already in the queue, so it may take up to 2 seconds + 1 move before changes in M220 take effect.

@tekstyle said in need conditional commands:

@OwenD

thanks for your help. i am not familiar with conditions and its syntax. this totally helps. does duet website have any information on other conditional commands that can be used ( not particular to this OP)?

Full documentation of the object model is still coming, but there is enough to get started here.

https://duet3d.dozuki.com/Wiki/GCode_Meta_Commands

https://duet3d.dozuki.com/Wiki/Object_Model_of_RepRapFirmware

https://duet3d.dozuki.com/Wiki/Gcode

Then it's a matter of poking around with M409 and testing using echo or similar

Both sound like good ideas

That worked. Thank you!

@techild
Glad you're sorted.
Might be best to mark thread as solved.

It's a simple manual bed leveling macro.
So far I have 3 macros level test1 to 3.
first 1 homes Z then G30 S-1 at that X Y location then moves X Y to right side of bed and does G30 S-1 prompts for OK or Cancel. If result of G30 S-1 matched the result of probe position 1 then I cancel else I adjust the bed screw at that point then hit OK, which repeats G30 S-1 in the same X Y position.

2nd Macro doesn't probe position 1 since I now know the result from previous probing., it moves X Y to the 3rd probe position and then G30 S-1.
I repeat the above as needed calling macro's 1 through 3.
Based on the outcome of a G32 bed level test, I could run 1 or more of the macros again.
The X Y locations match the outer 4 points that G32 probes.

If that makes sence..

Ok, that's interesting about the uptime. I realise my solution would have to wait for variables.

I also just discovered that I can use the M291 command to periodically check with the user if they want to continue. It's a useful workround for now.

@dc42 and @mwolter Thank you both for your help.
As I mentioned conditionals are not my forte.

I eventually got it working and am pleased with what it does.
I include it for anyone else, even the original above by @mwolter would work but tweaked what I knew I could tweak, namely I used 4 screw locations instead of 3.

This is for a RailCore II CoreXY with 3 Z motors but could probably be applied to anything else.

@OwenD said in M117 and Conditional GCode Statements:

Not sure if there's something screwy going on with caching in DWC here, but the same command sometimes works and sometimes doesn't

DWC doesn't display a message if it was exactly the same as the previous one.

works great...

Ahh awesome, thanks guys!

Define macro "StartStuff.g" or similar. Content:

M291 P"Run startup bed leveling and such?" S3 G28 G32 ...whatever...

This will result in a dialog on the web console:

99d9a6c4-b46f-48ff-b57a-b4a028bae2bc-image.png

Pressing OK will result in the rest of the macro (G28 and so forth) running; pressing cancel will end the macro immediately.

Test this; when ready to have it start every time, place

M98 P'StartStuff.g"

as the last line of config.g

p.s. No conditional gcode per se; this works right now, in all 2.recent and 3.recent versions of firmware, with or without a Pi.

Yes i think it'll be easy to get around, i just search ease x) but with your suggestion, i think it'll will be easy to do a bit of meta to ask which type of filament you are loading one by one 🙂

Yes, go to https://github.com/dc42/RepRapFirmware and click on Watch.

Lovely! Thank you!
