Project background
For my store customers
I wanted to offer free name engraving service on a plastic fountain pen.
The requirements were extremely simple: Just engrave a few letters, then fill it with colors.
After lots of watching lots of youtube. I ordered a 3018 CNC GRBL The generic kind.
Workflow
Then I began with this workflow
From Easel - create gcode / download gcode
Using Universal Gcode platform
I ran the code.
Results
The first few initial attempts came out beautiful.
Without writing the various settings
I started tinkering with the various settings in Easel
Now I have screwed up and the results are now horrible.
I can’t get it to do what I somehow did before.
Issue
So now about 5 or 6 hours of changing various parameters.
I simply could not get the initial results I got before.
So here I am … newbie asking for help.
Pics
From the pics below
You can see my name in red … it came out prefect.
Then there were these later attempts that were wrong.
I have tried these settings
-
Using Font Intro with 0.1mm depth with cut depth
-
Spindle speed 14000 / 16000
-
Material: tried ABS and Cast Acrylic
-
Bit: Setting … 0.1mm and also 0.01mm end mills
Since I did not have a pro account, I could not use Vbits. -
Changing the vbit … to see if the vbit was blunt?
-
Item to be engraved upon
Pen material: Polycarbonate PC -
The work area of the pen is about
Y= 5 mm X = about 30 mm
Really appreciate some help/pointer to let me know what the best settings are …
What I have done wrong …
Thanksssss!
