dxf2gcode might be a tool we need later.
they really can work without breaking because of the small stepper motors so they dont need end switches. very sturdy units.
for the cautious there is the right way to do things still yet more…
involves uploading the new firmware there is macos versions
https://github.com/netpipe/QT-AVRDude use baud 57600 (old bootloader)
https://github.com/netpipe/QT-GRBLSender
https://github.com/netpipe/qLaserEngraver WIP
https://github.com/netpipe/GCODE-Tools/tree/master/Engraver testing
https://github.com/netpipe/GCODE-Tools/releases/tag/mac my svg2gcode-qt app smooths now and potraceGUI is new for making any image into a svg or dxf
potraceGUI – from the gcodetools repo works great but you have to convert the bitmaps from gimp to 1 bit greyscale in the image->mode->indexed box
keep checking for updates to the same release files on github for new versions if its not working good otherwise file bug report on github.
change settings $20 – $22 to 1 and then you homing and softlimits will work after installing switches.
use GRBLSender app from bottom macos links to set the settings
optional firmware upload with AVRDude
grbl.hex this is 1.1h compiled with the makefile and
using candle / candle2 also works great
i changed this line on mac to do it
COMPILE = /Applications/Arduino.app/Contents/Java/hardware/tools/avr/bin/avr-gcc -Wall -Os -DF_CPU=$(CLOCK) -mmcu=$(DEVICE) -I. -ffunction-sections -flto
config.h
#define HOMING_SINGLE_AXIS_COMMANDS
#define HOMING_FORCE_SET_ORIGIN
optional mode for paralell wiring of switches if you want to compile it in.
// #define LIMITS_TWO_SWITCHES_ON_AXES
- basically fix the part to machine with tape on one side and 2 clamps it came with
- connect and home machine
- touch drillbit to peice of wood record the position of z axis then home again and set z to same value then zero Z button and click send after loading the gcode file

https://github.com/netpipe/GCODE-Tools/releases/download/mac/Candle2.app.zip
https://github.com/netpipe/QT-GRBLSender/releases/download/macos/QT-GRBLSender.app.zip for editing settings and sending realtime commands.
https://github.com/user-attachments/files/21337808/dxfplotter.app.zip here is extra app for DXF files or libreCAD stuff, basically ready to use with candle after you remove the comments from the .nc files after for Candle2 or just right click on the metadata line and delete after loading the gcode into candle (it will freeze on that line when trying to run anyway)
it generates gcode that does 3 passes to make the fonts that clean.
