| + | ===== Fine settings the bl touch height ==== | ||
| + | When printing with octoprint for example, babystepping is not available for fine tuning. | ||
| + | |||
| + | I follow the following procedure to precisely set the distance between the nozzle and the printer bed, after updating or to take a new mesh/repeat the automatic bed levelling: | ||
| + | < | ||
| + | G28 ; home | ||
| + | G29 P1 ; start the automatic bed leveling | ||
| + | ; wait for bed leveling to finish (should take about 5 minutes) | ||
| + | G29 S1 ; save the mesh information into slot 1 | ||
| + | G29 S0 ; save in slot 0 as well as Cura use slot 0 per default | ||
| + | M500 ; save EEPROM | ||
| + | M851 ; print the current setting | ||
| + | M851 Z0 ; set offset to zero | ||
| + | G28 ; home again | ||
| + | G1 Z0 ; move the nozzle to height 0 | ||
| + | ; measure the distance between the nozzle and the bed with some feeler gauge | ||
| + | ; or stack several piece of paper and measure the thickness | ||
| + | M851 Z-1.6 ; enter the measure distance, in this example, the head is 1.6mm above the printer bed | ||
| + | M500 ; store the new configuration | ||
| + | G28 ; home again | ||
| + | G1 Z0 ; move the nozzle to height 0 - Then mesure again, if it's not right yet, restart at step M851 Z-1.6 (increase the value to bring the head closer to the bed) | ||
| + | </ | ||
| + | |||
| + | Keep adjusting | ||
| + | |||
| + | If you need to change the height, simply do: | ||
| + | < | ||
| + | G28 ; home | ||
| + | M851 ; display current setting | ||
| + | M851 Z0 ; set offset to zero | ||
| + | G28 ; home | ||
| + | G1 Z0 ; move the nozzle to height 0 | ||
| + | M851 Z-1.7 ; the new value | ||
| + | ; increase if the first layer is too sick, 1.7 for example | ||
| + | ; decrease if the first layer is too thin/the nozzle scratch or hit the bed, 1.5 for example | ||
| + | M500 ; store the new configuration | ||
