If you are using Non-XYZ filament in your Da Vinci 1.0, you are probably resetting the filament-counter-chip in the XYZ cartridges (as I am doing). So you have to attach three leads to the chip (and attach them to your Arduino). This is a bit of a pain, so I built myself a chip holder. It consists of a base with three 24 gage wires looped through holes in the base (and twisted to stay) that the chip fits on top of. The second piece is a "clamp" that slides over the back of base to hold the chip down against the three wires looped into the base. Each of the three 24 gage wires are then inserted into the proper pin-outs on the Arduino board. Tiny raised letters on the chip-holder's base remind you where to insert the leads: "G" for ground, "5V" for 5V and "7" for digital pin-out 7. If you want to find out how to use the Arduino board and get the Arduino "sketch" (program) that performs the resetting, here is the URL: http://voltivo.com/blog/da-vinci-reset-eeprom If you have not bought an Arduino board yet, consider getting a Arduino Mini and using this other very slick thingaverse creation (by fr33 3n3rgy) that combines the Arduino Mini board and the contacts right into a module that plugs onto the bottom of the XYZ cartridge. You don't even have to take the chip out the cartridge case. Here is the URL: http://www.thingiverse.com/thing:302209Print the two parts. File the parts as shown in the picture in the gallery. The first couple of layers always bulge outward and these bulges must be filed off where fit is important. Also, inside corners always tend to be a bit rounded and need a filing to square them off. You'll need three 6-8 inch lengths of bare, 24 gauge solid copper wire. (I think 22 gauge will work as well - as long as it fits into the Arduino pin-out connectors.) Loop each wire though a pair of holes in the base and twist (on the bottom) to hold them in place. The left and right leads should extend straight down. But the center lead must be bent towards the front so that it is out of the way of the slide-on clamp. Take your filament chip out of the cartridge and place it on the top of the holder-base. Be sure to place the chip so the painted "corner-cut" lines up with the base's corner-cut. Slip the sliding clamp on from the back of the base to hold down the chip.
