Hello Robert,
I have adapted my C70 in a similar way. The middle top rollers were
removed and also the white plastic rear paper guide. In the front I
removed the middle star wheels. By using a 3 mm plexi-glass plate at
the backside on top of the power supply (with some holes in it for
cooling) to fill up the gap, I get a flat path throught the printer.
What kind of material do you use for the "custom bed"? I was thinking
about 0.5 mm aluminum, but that may ruin the abrasive roller coating.
The next challenge is to reprogram the printer such that it prints one
page from a preset reference y-axes position of the moving bed. How do
you control the y-movement?
With kind regards,
Gerard
