Machine design
Due to my team member give up in Fab Academy, so I have to do it by myself. My workload is heavy , so I choice a simply design "computer control engraving machine" following last week "Mechanical design"
1. control build: hardware
In control hardware , I use the following I use Arduino UNO as main board; Then add CNC shield to help me control CNC shield.
I add 24v power to CNC shield as following
2. code
- Download grbl library
- Add grbl library
- Open file- example-grbl-grblupload
- update to Arduino uno
3. model to gcode
software:Easel
Design model
Change cutter
Download gcode
4.control the machine
Download the Grbl Controller and click "OPEN " to connect CNC shield Then click the command to edit the parameter
5. Machine test
machine empty moving
machine engrave wax
After test, I find some problems and need to improve
- X stepper motor's torque is not bigger enough,so it can't move frequently;
- Belt is loose , and I will add spring later
