Conditional Code For daemon.g

Topher

I have a few tasks for daemon.g if I can get some help working out the bugs, that would be awesome! First up, I run a lot of different printers here so to streamline my slicer would save me some time as fans have different names in my case. Im trying to run a part fan based on height however I'm getting an error:

if job.layer >= 2	; Set part fan to 100% when print gets to layer 2
	M106 P1 S255

Error: in file macro line 1 column 19: meta command: cannot convert operands to same type

I believe this error is in reference to the "2" in my argument. What am I doing wrong?

@leckietech

job.layer will be null at the start of the print.

You need to allow for that

something like this should work

if job.layer = null
      M106 P1 S0
elif job.layer > 2
     M106 P1 S255

On another note, daemon.g by default only runs once every 10 seconds,
If you need to sample faster than that then you need to set up a loop within daemon.g

Ah! Makes so much sense, I knew it was going to be simple!

Thank you for the tip!
Next up, Ive looked throughout the Object Model and cant seem to find a node that keeps track of files being uploaded. We have so many printers here and so may operators, often we have someone run a print from an sd card while someone else is uploading. So logical solution: Change the LCD color and put a message on the screen "uploading file". I will also need a way to display on the screen if the file failed to upload - as this is something that happens here all the time.
Any suggestions on how to achieve this?

@leckietech
I can't see anything in the object model that would indicate when an upload is in place.
If it were anywhere I would have thought it would have been in state.status, but it doesn't appear so.

About the only way I can think of achieving what you want might be to use M559 or M560 to upload the file.
I think you'd have to have a script/program that first sent M560 to start the upload, then maybe send M291 to display a message, then send each line of your G Code file, finally follweed by  or M29 as required and M292 to close the message.

Thanks for the response. I did look into this, we load our files from the desktop, our phones, ipads, all kinds of stuff and we have thousands of files so loading the file by Gcode command or scrips might not be the way. I did however come up with another way to solve half the problem, at least.

I've made a system file: printBEGIN.g
We use Simplify3d - in the post-processing window Im using the following script

{REPLACE "G90" "G90 ; This is a trigger in post for M98 printBEGIN\nM98 P"printBEGIN.g" "}

G90 is the first command of the start of the print and there is only one for the entire slice file. This will point to M98 P"printBEGIN" which the very first line of that file starts with

M291 S3 R"Ready to run file?" P{job.file.fileName}

This will at least halt the printer and display the file via the 12864 screen on the printer itself as well as any DWC device running. The only issue is: S3D doesn't like the command with quotations in it.

The post command:
{REPLACE "G90" "G90 ; This is a trigger in post for M98 printBEGIN\nM98 P"printBEGIN.g" "}

Gcode output:

G90 ; This is a trigger in post for M98 printBEGIN
M98 P

The post-processor skips over the "printBEGIN" portion in quotes.
Any ideas?

@leckietech you might need to replace each double quote in the replacement string by something that the post processor will recognise as being part of the replacement string. That might be \" or "".

Topher

@dc42 I tried every combination of this, still no go. Jumped over to the simplified forums, seems it cant be done.

@leckietech are you running with attached SBC? If you are not, then you can omit the quotes around the filename assuming that it doesn't contain any spaces, semicolons etc.

Alternatively, create a global variable in config.g:

global printBeginMacro = "printBEGIN.g"

then in your script you can use:

{REPLACE "G90" "G90 ; This is a trigger in post for M98 printBEGIN\nM98 P{printBeginMacro}}

if S3D doesn't mind the embedded { }.

Yet another way: pick an unused M-command number such as M990, rename printBegin.g to M990.g, make sure it is in /sys, and use M990 instead of M98 P"printBEGIN.g".

I had no idea this could be done! Thanks so much! These tips will get put to use in other ways, too, now that I know about them! Is it possible to use G commands as well? ie, G110

Answered my own question - G and M commands can be used. They also can not be in their own folder ie a folder calledCustom Gcodes
