Hi PeterE Filament extrusion min temperature is written into firmware which will override any other commands, including gcodes, if they attempt to exceed the printer capability. So it will only work with elevated head temp. Best regards Picclock |

Ah, OK, thanks, then I don't have to go that way. BR /Peter |

I found the reason for why the Y axis motor growled - I had misplaced the connector on the RAMPS board such that only three of the connectors were connected :palm: After re-positioning the connector the sound of the motor was like the rest. But now the motor only runs in one direction :bang: I guess I have crashed the driver. Will test using the extruder driver and hope for the best. /Peter |

PeterE: When I was setting up my 3D printer and checking the calibration on my Bowden tube extruder I used the jog, or "Move Axis", function on the LCD screen. I selected to jog the extruder, disconnected the Bowden tube from the extruder, told it how many mm I wanted it to move the filament, and then measured the actual movement. It measured to within +/- 0.02mm of what it was supposed to be. I figured that was close enough and motored on to the next calibration step. I think that I'm finally starting to get past the vertical portion of the learning curve. Good luck. Don |
| PeterE:
Hi Don, Thanks for the tip :thumbup: I think I saw that alternative when jumping around the menu choices of the display. Will try for sure. Totally agree about the steep learning curve, but in the end it is rewarding. BR /Peter |
