After many faithful years of service its time to replace my Phlatprinter MK1, so I fired up sketchup to see what I could come up with using Openbuilds parts and custom plates. Before going any further Id like to get some opinions on the design- Not sure just yet how I will operate the pressure roller actuators, I could use a pendant or jog buttons to raise and lower them manually, or would it be possible to use gcode? as in have it lower the rollers to a preset height at the beginning of a cut and then raise up after the sheet is done? Do u think I really need 2 steppers to operate the drive rollers or could I use just 1? I plan to make the drive rollers from abs just like Mark did on the original phlatprinter but have the endcaps 3d printed, simple but has worked just fine on my phlaty for many years, they will be on 5/8 keyed shafts riding on flange bearings with lock collers. I plan to use the planet cnc 9 axis board with this because Im going to be slaving 2 steppers if I use 2 to drive the feed rollers. Its sized by starting with a 1000mm cbeam and working around that, which gives me enough room to run a sheet of dollar tree foam board lengthwise. Any ideas? Improvements? Changes? Am I doing anything I might regret later? Any feedback welcome- Fred Is there a trick to uploading files? wont let me upload the skp. file? Thanks Rick that did it- This is just a rough draft, there are mistakes in the model, once Im sure of my final design Ill rebuild it to exact measurements- Goals: Cut foam, up to 4" thick, balsa, lite ply and carbon sheet.
