Subject: Re: [Homebrew_PCBs] Homemade flatbed inkjet pcb printer

Hi Cristian,
It was an another option but since head load is not too much CNC machine could be a burden and printers are not vector based devices.
On x-axis indeed you don't need any feedback during printing. Your firing positions come from linear encoder by this way you can run motor (x-axis) freely.

You need a clean area to avoid any dust because of that I don't know whether it is a good idea to use the same machine for drilling/printing or not. If dust is on the trace, sometimes it becomes a part of resist but if it is between traces then it can create a bridge.

One more thing that forces me to use Epson's X-axis and piezo head holder is the mechanical alignment of the head and you need to cover inkjet head at parking position to avoid ink drying.
I tried to make things easier at the initial phase of the project.

Cheers,
Volkan

Why not use a CNC Drilling Machine instead of a new XY mechanism?
You can attach the printing head to the CNC Machine's tool holder.
If you can software align the printed holes with the drill position,
you'll get a full PCB machine: drill, print, etch.
