Flashforge Creator Dual / Pro How to fix Dual Extruders dragging across prints.

All,
The tool you are looking for to measure gaps is called a 'feeler gauge'. You can get them in English (.00x inches) or Metric (.0x mm) and they are cheap as can be. $10 USD or less, and found in almost any automotive store. Each blade is a different thickness and usually made of hardened steel. The English one I have is .001, .0015, .002, .003 inches and on up.

I measured the print head card that came with the FF Pro and it is 0.19 mm thick. A feeler gauge is used in the same manner.

Here is a metric one on Amazon so you understand what I am referring to http://smile.amazon.com/Metric-Thick...r+guage+metric.

• The print nozzles need a 9mm wrench to remove the brass nozzle, I prefer a socket and finger tighten only. A socket will also shave off most of the plastic gunk melted on the nozzle. A 'nut driver' would probably be better if you don't already have a socket set.
• And a 5/64 inch (2mm) drill bit will clean out the nylon tube, slow speed and please don't drill through your finger. You can buy individual drill bits at Lowes or Home Depot.
• An 'inspection mirror' allows you to find the screws holding the print head assembly to the carriage without bending over. A short one is fine, or use a ladies 'make up mirror'.

Here in the US an inexpensive place to get these items is Harbor Freight. Also you can find these items at Sears. Not sure if Lowes or Home Depot carries feeler gauges.
Hope this saves you some time!
