Description

Spring loaded craft cutter attachment for RichRap's awesome QuckFit carriage. It allows for the blade tip to be aligned with my Jhead extruder so there is no mucking around with Z stops and such when I switch over. I'm sad for the lack of vector to 3d print software available.

Instructions

You will probably need:

1 - Plate print
2 - WingClamp prints
8 - 3M x 25 bolts
22 - 3M washers (if you like to use washers)
6 - 10mm springs from cheap "Bic Pencil #2 0.7mm" mechanical pencils.
1 - Vinyl cutter blade holder that is around 11 mm diameter. ( ebay.com/itm/330651969471?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 )

Dimensions

Plate:
100mm x 26mm (There should be a specified standard for the QuickFit but I just don't know it) I measured the one I have.
20mm Center hole is in case I ever want to fit a gear for blade adjustment.

WingClamp:
~5mm for compressed spring between Plate and WingClamp, 45mm from end to end. When mounted to the plate, the bore for the vinyl cutter is 12mm.

The idea is that you set the blade for the depth you want to cut, then let the flat nose drag around on the material. And after initial calibration, you won't need to readjust the z-axis to change it out ever!

Ah thanks, I had the wrong extension. Though still no luck using your modified version. With the unicorn extension I can get some of the graphic to show on the bottom left corner as if it's centered on 0,0. With your TOM version it won't show at all. I'm using pronterface, thinking maybe I should be using something else. But dang, g-code is g-code and should work the same no matter what software I'm interfacing with. Either way I get this error when starting the print:

Error:No Checksum with line number, Last Line: -1
Resend: 0
Error:No Line Number with checksum, Last Line: -1

I did finally get this Thing printed. There are some design flaws in the Wing that make for some funny print methods. I'm seeing that there are so many better ways I could have done this :) Anyway I did some manual testing cutting a piece of paper. My bed isn't very level at all and it seems to cut pretty well when I slide the axis around by hand. I practiced my cursive :) I will need to get a tacky mat and figure out this g-code situation.
