STL files printing stops in line 19
December 23, 2012 08:47AM
Hello all,
i am a new user and i have build an Mendel. All motors seems to work and i can feed the PLA whem the extruder has 185 degrees. All with no problem. But when i load a STL file, the head is going into start possition, leftfront, and then happens nothing.
I only can see in the software that it seems to stop at line 19.
Please can anyone help?

Can you attach the g-code, it is easier to spot the error there.

Prusa with cast PU parts, RAMPS 1.3, Wades extruder, J-Head hot end

M109 - its waiting for your hot end to reach temperature. Did you preheat it beforehand? If not you'll just have so wait for it to heat up. There should be a cryptic message appearing in the log showing the temps, and you can watch it increase. Things should start moving when it reaches 200 degrees.

I prefer to heat things up before hitting print. This allows me to do some last second extrusion to make sure the extruder is primed and ready.
