The detection drift became more significant. I tested multiple sensors and conditions, leading me to conclude that a physical probe was necessary.\r\n\r\nThis mod uses the stock Z-endstop sensor, requiring only an extension of its wires so it can move with the X carriage. \r\n\r\nI also didn't like manually moving it up and down for bed leveling, so I developed a lifting mechanism to raise at the end of bed levelling and lower after each print is complete.\r\n\r\nTo implement this mod, insert the following start and finishing G-code into your slicer. (PLEASE NOTE: I run all start and end G-code scripts directly from my Octoprint. SO these codes may not work for you as is, please review it carefully and adjust what's necessary to get it working.)\r\n\r\nSTART CODE\r\nM190 S95 ; My Octoprint handles the heat up of my bed to 95c (I only print ABS)\r\nM109 S230 ; My Octoprint handles the heat up of my nozzle to 230c (I only print ABS)\r\nM92 E415 ; I have a Bondtech, so I need to adjust my E-steps ((REMOVE IF YOU ARE STOCK))\r\n\r\nG28 ;Home\r\nG29 ; Bed level\r\nG1 Z100 F700\r\nG1 X315 F1000\r\nG1 Z-2 F500\r\nG92 E0\r\nG1 F200 E80 ;pushes filament into the heater block and primes it.\r\nG92 E0\r\nG1 Z1\r\nG1 Y270 F5000\r\n\r\nJOB FINISHED and or CANCELLED\r\nG28 X0 Y0\r\nG1 Y300 F3000\r\nG1 Z20 F500\r\nG1 X315 F1000\r\nG1 Z100 F800\r\nM84\r\nM106 S0 ; turn off cooling fan\r\nM104 S0 ; turn off extruder\r\nM140 S0 ; turn off bed\r\nG92 E1\r\nG1 E-40 F500 ;retracts filament (effectively doing a hot pull so less filament is left in the heater block during heat ups to lessen burning clogs) \r\nM84\r\n\r\nTo make this mod work, you must modify your firmware to enable auto bed leveling and increase the additional X-axis movement to 315 instead of 300. The purge bucket works about 80% of the time; it just saves the printer from drawing lines of purge material.\r\n\r\nYou will also need to know how to set the Z height offset of your probe versus the height of your specific nozzle. \r\n\r\nI disclaim any responsibility if you use this mod and break your printer / your equipment / yourself / your family / your house. TOTALLY YOUR OWN RESPONSIBILITY. \r\n\r\nTo assist you, here are the Marlin files to flash the firmware. \r\nhttps://drive.google.com/drive/folders/1o48aMIfPh2HTFBpTwazNd4TIGl5y1VHX?usp=sharing\r\n\r\nAll files are there if you just want to edit or reconfigure; There's also a tutorial for the Z offset. (read PDF) download into its own folder to make things easier.\r\n\r\nIf you just want to flash it, use the file named.\r\nMarlin.ino.with_bootloader.sanguino.hex\r\n\r\nI disclaim any responsibility if you use this mod and break your printer / your equipment / yourself / your family / your house. TOTALLY YOUR OWN RESPONSIBILITY. \r\n\r\nAnyway, after all that, I hope you have fun :) \r\n\r\nFINAL NOTE: IF YOU PRINT ALL THE FULL Y AXIS LENGTH YOUR CARRIAGE WILL CRASH INTO YOUR PRINT AT THE END OF THE PRINT. PLEASE ALLOW SPACE FOR CARRIAGE TO PASS IT!!!\r\n\r\nI disclaim any responsibility if you use this mod and break your printer / your equipment / yourself / your family / your house. TOTALLY YOUR OWN RESPONSIBILITY. \r\n
