can't print anymore

[cancermachinist]

Have had the Orion for about 2 weeks and now it refuses to print. if the part does stick, the machine after a short time goes into idle.

also seem to be having problems with the print head not extruding.

It sounds as though you may have a Z height problem where the height is to high and the parts will not stick or the height is to low and being that close to the glass prevents the
filament from coming out. Download the second edition of the Orion users manual here: http://www.geneb.org/orion/OrionUserManual-2ndEd.pdf
Follow the chapter on adjusting Z height.

thanks, I have checked level on the head with a dial indicator and done the z height ritual with a piece of paper just as I would on a CNC mill but I will check those again. I guess I should have added in the question the first time that when I disable the stepper and manually feed some filament it seems very resistant. the temp is set for 220c for the ABS I am using. another step I have just done is I popped open the feed tube at the print head and manually pulled a length of filament that seems damaged as though the feed roller has been spinning in place and cut the section from it and reloaded as though it were a new filament. we'll see how that goes too.

You can try 230C on the ABS. If the filament is very resistent to extruding while you are doing it by hand it indicates that the printhead is not hot enough or a clog exists somewhere. I also recommend the purchase of an inexpensive
thermocouple meter that you can put into the hotend while it is hot to verify the temperatures reported are actually the temperatures that are present. Obviously you have to remove the filament. Some people report that they can loosen the nozzle and sneek the
thermocouple in the small gap between the nozzle and heat body. Just throwing out the things people have done. Do NOT exceed 240C on those HotEnds because you will melt the PEEK plastic that is part of the HotEnd.
Here is a link to an inexpensive thermocouple meter: http://www.amazon.com/AGPtek-Channel-Di ... uple+meter
You cannot use the infrared type of meter because they can not properly work on reflective surfaces.
