| - | ===Calibrating Extruder Steps per mm=== | ||
| - | ** Written for JGAurora A5S, using custom firmware. Coped from post by [[https:// | ||
| - | If your printer is over or under extruding, you may want to calibrate your steps per mm. | ||
| - | |||
| - | - Ok. So validate your M92 E415 is saved in EEPROM: | ||
| - | - Turn off the printer | ||
| - | - Turn on the printer | ||
| - | - Go to the Change Menu and check Esteps are still 415 | ||
| - | - Or plug in Pronterface and do: | ||
| - | - M503 | ||
| - | - Then, validate you get 100mm of filament when you SLOWLY extrude 100mm of filament through the extruder (with the bowden tube disconnected, | ||
| - | - If not, then further refine your Esteps. | ||
| - | - Then you will need to change the Load/Unload length (don't change the Esteps as that will muck up your prints). | ||
| - | - There may be a menu item to do this. If not you can set it through Pronterface. | ||
| - | - Calculate how may extra mm you need to manually extrude after a Load Filament function. Then: | ||
| - | - M503 | ||
| - | - And look for the M603 line which shows the (L)oad and (U)nload lengths. ie: M603 L460 U600 | ||
| - | - Add the extra mm to both of those values and save them back to EEPROM, ie: | ||
| - | - M603 L490 U630 | ||
| - | - M500 | ||
| - | - Verify with M503 | ||
| - | - Then test the Filament Load and Unload buttons again. | ||
| - | - Repeat until you get satisfactory results. | ||
| - | |||
| - | P.S. after all that, you should probably calibrate the Extrusion Multiplier, for each filament type (PLA, PETG, TPU, etc) so that when you request a 0.4mm line, you get a 0.4mm line. | ||
