gcode | print something on your 3d printer | 3D Printing library

I’m just re(learning) python after 5+ years of inactivity; it doesn’t help that I wasn’t great at it to begin with though… Here is what I’m trying to do:

1. find a sting in a file and replace it with another string (G00 with G1)
2. find all of the instances where a line starts with a specific string and concatenate a string on it at the end
3. The original file aaaa.gcode remains untouched and all of the changes are saved to bbbb.gcode.

Individually both sets of code work as expected. I’ve tried lots of different ways to add both sets of code together, but nothing works.

Sample file (C:\gcode\aaaa.gcode)

I'm trying to connect to a printer server to be able to save the printing files directly in the printer storage. I'm able to do it using the curl curl -v -H 'Content-Type:application/octet-stream' 'http://192.168.1.125/upload?X-Filename=model.gcode' --data-binary @model.gcode Now I'm trying to add this function to a Flutter app but don't works.... So now I am trying to debug the code using a postman server. Can you help me to create a postman server mock to upload the file as binary, like in this curl code?

I have an actix web service and would like to parse the contents of a multipart field while streaming with async-gcode and in addition store the contents e.g. in a database.

However, I have no clue how to feed in the stream to the Parser and at the same time collect the bytes into a Vec or a String.

The first problem I face is that field is a stream of actix::web::Bytes and not of u8.

I would like to produce a rose tree representation (called Header in the following) of a data type using generics-sop, but I got stuck at one detail; specifically, how to pass type information "one level down" within the implementation of mkAnonProd such that when unpacking anonymous records the right instances of HasHeader for the field types can be picked rather than the unit type.

In the following I have pasted my own code, some test datatypes and a GHCi session that illustrates the current and desired behaviour.

I want to dynamically add the selected attribute to option of select drop-down list.

So something like this

I recently got a small 300mm bed CNC Machine that has it's issues, which isn't really relevant, but to fix those issues I need to ask my friend. He has quite a lot of experience working with CNC Machines, but even when I screenshared the GRBL Software, he couldn't fix some problems that he said should be a simple fix, hence, the node.js app. I would like to connect a Raspberry Pi up to the CNC Driver board, host a server on Heroku, and have him connect to the server. The server would then pick up his input, translate it into GCode, and push it to the Raspberry Pi (which would send it to the driver board). I know how to set up the server, even code it so that he can press a button and it translates to GCode, but my question is, how could the Raspberry Pi get the Node equivalent of a message telling it the GCode the user wants to push? I have some experience with Node.js and have made a Chat Application, but this seems a little different. Thanks in advance.

I'm doing on a GUI to extract position X and Y from GCode by using Regex and print it on richTextBox.

I am currently working with python and I have some real trouble with the syntax. I wanted to include a Cura command-line into my script but I do not know how to actually parse the line so that the command will be executed out of my Blender Script. My code is the following and I really do not know if this is even valid:

I'm programming a PL/SQL function to check datesand return a date. The problem is that testing the function isolated I've obtained error about the cursor use. ORA-01001: cursor no válido or in english, not valid cursor.

I use two arrays to save different kind of dates. But the error comes in the FOR ... LOOP loop. A priori is well defined the cursor and the rowvariable. And I've checked and the row variable contains rows, the query returns at least 5 rows. Here the code of the function :
