Flip/Mirror G-Code Online Tool

What is G-Code Flipper?

G-Code Flipper is an online tool designed to help users flip or mirror their G-code files. It supports adjustments along the X-axis or Y-axis, ensuring prints are correctly oriented.

Key Features

File Upload

Upload your G-code file directly into the tool. The tool will read and prepare the file for further processing.

Flip Options

The tool allows you to flip the G-code along the X-axis, Y-axis, or not flip at all. This helps in achieving the desired print orientation.

Visual Representation

G-Code Flipper provides a visual representation of the print before and after flipping. This ensures users can verify changes before proceeding with printing.

Automatic Mesh Detection

The tool automatically detects the start and end of the print mesh, accommodating different slicers:

Start Line: Identified by the first occurrence of ;LAYER:0 or ;AFTER_LAYER_CHANGE
End Line: Identified by the last occurrence of ; stop printing object … or ;TIME_ELAPSED: …
(Cura and Orca Slicers)

If the tool fails to detect these lines, it prompts users to manually specify them.

Download Adjusted Files

After flipping, users can download the adjusted G-code file directly from the tool.

How to Use G-Code Flipper

Upload Your File: Select and upload your G-code file.
Set Print Bed Dimensions: Input the dimensions of your print bed.
Choose Flip Direction: Select whether to flip along the X-axis, Y-axis, or no flip.
Review and Adjust: Check the visual representation of your print before and after flipping.
Download Your File: Download the adjusted G-code file for printing.

3D Touch (BL Touch Clone) Klipper fix for Ender 3

Miro Hristov — Fri, 23 Sep 2022 06:21:44 +0000

This is mostly for my own reference but it may help someone in need. The 3D Touch finally works after a lot of trial and error.

Important settings:

stow_on_each_sample: True
probe_with_touch_mode: False

pin_up_touch_mode_reports_triggered: False

The last line is set to false even though the Klipper test reports true!
You may need to try a combo of true and false of these settings.
I’ve seen other threads set pin_up_touch_mode_reports_triggered to true to get it working depending on the model.
stow_on_each_sample is slower but it doesn’t work as well otherwise.

Here’s what it looks like when NOT working:

Some keywords: 3D Touch not working, blinking fast. BL Touch Clone (3D Touch) fails calibration. Red Blink. Blue Blink.

Here’s my entire printer.cfg — keep in mind it has pressure advance, bed leveling, etc. custom settings.

# This file contains pin mappings for the stock 2020 Creality Ender 3
# V2. To use this config, during “make menuconfig” select the
# STM32F103 with a “28KiB bootloader” and serial (on USART1 PA10/PA9)
# communication.
 
# If you prefer a direct serial connection, in “make menuconfig”
# select “Enable extra low-level configuration options” and select
# serial (on USART3 PB11/PB10), which is broken out on the 10 pin IDC
# cable used for the LCD module as follows:
# 3: Tx, 4: Rx, 9: GND, 10: VCC
 
# Flash this firmware by copying “out/klipper.bin” to a SD card and
# turning on the printer with the card inserted. The firmware

Normal Map Rotation Tool (Online)

Miro Hristov — Mon, 18 Oct 2021 06:38:54 +0000

Try Normal Map Rotator V3 - BETA

ISSUE:

A challenge that arises when attempting to rotate a normal map in Photoshop is that the software does not consider the direction of the map’s vectors from the RGB channels. As a result, rotating a normal map by 180 degrees in any image processing program will result in an inversion of the normal strength – elements that should protrude will appear recessed and vice versa.

SOLUTION:

After exploring various options, I developed a tool of my own. By utilizing three.js, I am able to apply the original normal map to a plane, rotate the plane, render the plane using a Normal material texture, and the final output takes into account the rotation of the normal map.
