Pre-spindle upgrade.
Dremel 4200
Eagle > PCB-GCODE > OctoPrint.
3 ops. Etch, Drill and mill.
It’s not perfect. But all the boards work.
Did you do any auto-levelling of the PCB to make sure you got no air traces in low spots of the board? Did PCB-Gcode generate those tabs with the 3 holes drilled in each tab (I don’t recall PCB-Gcode having a tab feature)? How low in the Z did you go to mill the traces?
No auto-leveling. All the lower traces came out okay. Not perfect but useable. The milling and the drill taps I made manually in Eagle. I used a 20 Degree 0.1 bit and the Z Down was set to -0.1025
Nice work. I’m amazed all those traces came out ok without auto-levelling. You must’ve had a pretty non-warped board. I find with auto-levelling that PCB blanks can be 0.3mm off in some spots. I found running an hour long PCB job and then having air traces killed me.
Thanks! I have not added the necessary components for auto-leveling. I am going to wait till the machine gets to it’s final size and the control box is completed. But I am pretty stoked about not having to use photoresist any more.
That’s pretty look!! 
Is that a custom branch of Octoprint? Are you using a Marlin based firmware?
Heavily modified version of Octoprint.
Do you have a github location that you are willing to share that I can pull from?
Unfortunately I don’t have this on github. I am not a coder by trade. This is something I made so it was consistent with the other instances of octoprint I have (3D Printer & Laser Engraver) its heavily modified for my workflow and other peripherals connected to the shapeoko. i.e. addressable LEDs to status alert and Pushover for push notifications.
If I have time in-between projects, I’ll clean it up and dump it on github.
I’d love to see the code and play with it. My ultimate goal is to have your setup with different heads i can mount oh the z to change the type of machining process, cnc, 3d print, lasercut , or 3d resin print.
