For me solution was define MIN_PROBE_EDGE 35 (before that be sure your bed have correct size and correct nozzle_to_probe offset) Right now my bed has full 230mm of reachable space without collision with frame. I know I know , just another direct drive. Believe me or not but I just didn't found one what will satisfy all I need ( or want) what was that? - I have mirrored BMG clone - using BL Touch (clone) - with stock hotend and cooling - without sacrificing any of Z or X dimension - left motor position - precise and rigid - with cable mount - preferably exchangeable cable mount if I decided to go with cable chains without need to disassemble whole direct drive I found one: this from PrntBear and this one from QCPassed ( so credit to him for nice shape) And it inspire me to draw one from scratch. It has simmilar shape( I like that), but especially I payed attention to precision, rigidity and cables. Printed with PLA and working well. If you decide that you want different cable management ( chain for example) I included step file for that part. #####NOZZLE_TO_PROBE_OFFSET { -44, -15, 0 } EDIT: added one without BLTouch EDIT: new third generation added - rebuilt to offer even more rigidity and precision. Not so fancy but functional and stronger.
