bash shell script to adjust temps-setting for any temperature-tower

thingiverse

Main-Purpose: This Script Is Meant to Be Applied to Your Favorite Temp-Tower The Script Will Add Desired Temp-Changes According to Your Wishes Via Options. There Are Many Good Temperature Towers Available. However, The One I Am Providing Here Is Not the Best - Thingiverse Wants a STL-File, So I Am Giving It Instead. Being Sure That the "Desired" Temperatures Are Applied Is Some of the Problems. I Decided to Write a Bash Script Which Uses a Sliced Gcode-File and Inserts User-Customizable Modified Temperatures to Fit the Tower. It Runs Nicely Under WIN10 with E.g. Ubuntu Installed as App or Of Course in Any Linux-Distribution. The Usage is Quite Simple: - Use Your Preferred Temp-Tower and Use a Slicer of Your Choice. Slice It. - Make Downloaded Script Executable Via Chmod +x ./Insert_Temp_Changes.sh - Launch the Script, At Minimum Provide Your Sliced Gcode-File as Input Via -i Option. This Will Then Use Defaults, Which Is: Start at 180 Degree, End at 220 Degree, 5 Degree Steps, the Modified Output Will Be Output.gcode. The Lowest Temp Will Be the Bottom and Increase. The Script Allows Options to Set Start-Temp, End-Temp, the Steps in-Between, the Name of the Output-File, and It Allows a Reverse-Knob. Using the Reverse-Knob Will Have Highest-Temp at the Bottom and Lowest-Temp with Increasing Layers. Full-Blown Command: ./Insert_Temp_Changes.sh -i 180-220_PLA_Temp_Calibration.gcode -b 180 -e 230 -s 10 -o Result.gcode -r Using This Temp as Start: 180 Using This Temp as End: 230 Increasing Temp Steps: 10 Reverse_Flag: 1 Input_File: 180-220_PLA_Temp_Calibration.gcode Output_File: Result.gcode The Provided Gcode-File Gets Analyzed and the Total Amount of Layers Extraced. Based on Desired Steps, the Script is Aware How Many Layers Are of Equal Temp and When the Next Temp-Change Is Required. Amount of Gcode-Layers: 311 Amount of Temp Changes: 6 Amount of Layers Until Temp-Change: 51 The Script Helps to See If the Changes Make Sense by Several Output, E.g. to Grep Through the Resulting Output-File for Any Temp-Settings. Temp Added by the Script are Marked with "Added_Modified_Temp". Checking the Modified Gcode-File and Display All Temp-Sets: 11:M104 S225 ; Set Temperature 16:M109 S225 ; Set Temperature and Wait for It to Be Reached 17:M109 S230 ; Added_Modified_Temp 5844:M104 S220 ; Added_Modified_Temp 12448:M104 S210 ; Added_Modified_Temp 18079:M104 S200 ; Added_Modified_Temp 24623:M104 S190 ; Added_Modified_Temp 30325:M104 S180 ; Added_Modified_Temp 37117:M104 S0 ; Turn Off Temperature First Tests Are Working for Me. If You Think the Script Has Issues, Kindly Let Me Know. Thanks, Christian
