Gcode Replacement

Fabrizio

Hi! I am trying to use the gcode replacement tool from RepetierServerPro

I have a lot of gcode generated in my RS, (about 8gb)

I have changed some of my machines from stock heatbreakers to bimetal heatbreakers, this requires a change in printing temperature and I was trying to automate it

I found that my gcode looks something like this

M104 S195

M105

M109 S195

Then try going to: PrinterSettings/G-Codes/Remplacements:

In "Regular Expression" try putting ^M104 S195$

and in Gcode to Execute "M104 S205"

Same for M109 S195

But nothing happens, I don't understand where I'm failing

Did  you send test command manually for testing or use our temperture setting widget. I ask because we also add a T0 for extruder 1 to the gcode. The expression looks good to me if it matches 100% the code. If you always need to add 10˚ you might try something like this

Expression: ^(M10[49]\s+.*S)(\d+.?\d*)(.*)$
Replacement

@if {{@2 > 50}}

@1{{@2 + 10}} @3

@else

0

@endif

this cover M104 and M109 also with extra parameter and adds 10˚ for more then 50 so off still works correctly.

It doesn't work for me, copy the commands I see in the console.

after that just cancel the print

I also attached the image of how I copied your code

Thanks

I also have some gcode with a temperature of 200°C

This code would increase them 10°C, so would it leave them at 210°C? Is that so or am I misinterpreting it?

Repetier

Line 4 is missing a at sign before 0. Forum likes to eat some chars so that is missing for anything below 50.

Since condition is anything above 50 gets 10 added yes 200 becomes 210. Worked for me. If you do want a uppe rlimit add a extra condition to the rule. @2 contains the temperate to set.

add the at sign before the 0 in the fourth line but the temperature still doesn't change, I don't know what I'm doing wrong...

For me it was working in my tests.
You can add a extra line like
M118 Changed

to see if it tried to replace at all. With sich changes it is alwazs the question if expression is not recogniced or if the replacement is not working for some reason.

add the command

I don't know if I should add an at sign in front or not, so add with and without at sign

and I don't see any message in the console (I think that this command would show me the message "change" in the console, right?)

I copy the capture again, to know if you see something where I could be wrong

I think I know why it did not work. Did you send the gcode as print job or manually. Just discovered that the replacements were not applied to print jobs. Fixed that for next release.

However if you just want it for print jobs you can go to Printer Settings and add a offset to your extruder, which does this addition inside print jobs.

Fabrizio

Try sending the job from Projects, From the printer with the "DirectPrint" button and from the Gcode that I have saved in the printer in "Groups"

In neither case did the script work.

With the Offset I was able to solve the problem, but I would have liked to use the script to put an upper limit on the temperature (because I have some segmented gcode with the temperature already modified)

Is there a way to download all the gcode from the server and upload them again? I think I could make a script with python or java and modify them on my PC, and upload them again, is this possible? I didn't find a way to download all the gcode together, if I can do it one by one, but it's quite a long job that I don't want to do.

We have just released 1.4.9 where I have the replacement bug fixed, so you can use our first solution. Just don't mix them.

Reuploading does not fix the issue, this is a runtime replacement.
