At first let me make a big thank you to Ryan for creating and sharing this creative and unique design with us. I really like the full support of the longest axis without the need of an expensive linear guide.
Pics or it didn’t happen:
Meanwhilst i’ve added a pencil mount and endstops (dual on Z and Y) and the device is drawing fine.
However i have got one issue/question:
I’m using the Marlin firmware for now (as long as it will suit my needs) with a Ramps 1.4 Mainboard to “print” from SD. But how can i set the workpiece zero point?
My approach for now is to move the device over to the zero point and reset the device. With a pencil (on z=0 touching the workpiece) this is working ok’ish. However once i reset the machine the z axis falls down, so any other workpiece zero than z0 will fail. For milling this approach won’t work. Also when i support the Z axis during reset it’ll start zeroing the Z-axis upon “print” if there was a router bit on, plunging it through the workpiece…
Further than that, i’m amazed already by what the machine can do. Started the build on Saturday (printed Wednesday through to Friday) and on Sunday it was able to plot, just amazing.
