Guide to first Rapman steps and settings

"... Then manually extrude about half a meter of filament at the temperature you set in the G-code file. See if the plastic flows as planned, i.e. 5mm/second ... Always extrude at least 30 cm of plastic at high temperature (e.g. 248 for color ABS) before running the file. When we started printing from a "cold" situation without extruding some plastic before hand, no plastic came out at start and then the nozzle would get stuck in some mess... If you plan to print a larger object, e.g. 12cm long, then make the raft temperature higher than 235 or 238 (my standard setting). The plastic will warp more and therefor attempt to rip it off. I don't have any setting yet, but I'd go for a temperature of 240 or higher and a yet fatter raft, e.g. set M108 to S600.0. But don't blame me if you can't get it off the print bed. Play it incrementally :) ..."

Extruder setup instructions

"... Take care with the heater and thermistor wires to ensure they do not touch and that they remain insulated from the support structure. ... The result of not doing this [including insulation ring] would be very difficult starting, the plastic goes soft a long way up the PTFE. This will work the first time but after it has cooled the extended melt zone takes a long time to soften again. If you run the extruder like this it will most likely cause a mechanical failure. ... If its impossible to get a flow by hand feeding, increase your temperature in 5 degC steps until you can. ..."
