Anycubic Kossel BLTouch V2.0 (and new effector)

thingiverse

This is a major update for my original BL Touch probe mount on the Anycubic Kossel, and like most things in life, it's evolved. In the end, it required several new components. The previous version can be found here: https://www.thingiverse.com/thing:2251115 Note that this will not fit the stock hotend, which is 25mm in diameter. I'm using a custom hotend with a 22.25mm diameter, available on Amazon: https://www.amazon.com/gp/product/B010MSTVZO/ref=oh_aui_detailpage_o06_s01?ie=UTF8&psc=1 This update also requires the use of a new effector plate. To get the BL Touch tucked in closer to the hotend and gain back printing area, I had to move the hotend under the effector. This updated version includes a new effector plate, clamp, and cooling duct. The effector has mounting holes for the BL Touch. The plate is connected to the rods using captive nuts, and I've made no significant changes to the rod configs in the firmware. The BL Touch is close to the hotend, but it's shown no issues being that close. All of these parts are printed in PLA, and I've seen no issues with melting etc. at this point. I've been printing a lot of PETG lately up around 250 degrees Celsius, and have not had any problems yet. However, you may want to print these in ABS or PETG or other high temp filament of your choice. I'm using two 30mm fans for cooling - one for the hotend and one for part cooling - and have not had issues. Here are my basic settings for the hotend and BL Touch: X_PROBE_OFFSET_FROM_EXTRUDER +0.4 // X offset: -left +right [of the nozzle] Y_PROBE_OFFSET_FROM_EXTRUDER -22.6 // Y offset: -front +behind [the nozzle] Z_PROBE_OFFSET_FROM_EXTRUDER -1.85 // Z offset: -below +above [the nozzle] You will need to redo the Z distance between the print bed and your endstops. MANUAL_Z_HOME_POS 268.85 // Distance between the nozzle to print bed after homing Do not blindly use these settings! You must use the correct settings for your machine. After mounting, manually move the hotend around the printing area and find your limits. You can either adjust your printable area in the firmware or remember to allow for clearance when placing items to print. I have a small issue with fan clearance on the right and rear uprights and the glass clamp on the front. I used supports on everything, but they may not be needed on the plate and clamp. I'm using S3D, so supports are very easy to configure and remove. The cooling duct will require supports. However, you might be able to print it standing up (laying on the fan mounting face) and get away with no supports. I have not tried this. The plate was designed with mounting holes for the duct, but I made several changes, and the mounting tabs don't line up. In the end, I just drilled small holes (1.5mm drill bit) in the plate using the duct as a template. The duct is secured using two 2mm cap screws. I may redo the part cooling duct to be a little more focused, but so far it seems to be doing a decent job. The BL Touch mounts using 2mm hardware. I am using two nuts (one on each side) as spacers between the BL and the plate, but depending on your setup you may need more or less spacing. Be sure to rotate the hotend in the clamp so the heat block is not touching the duct.
