First post but ive been reading and trying to learn few a few months, I've tried to expand my k40 laser using v-slot and its not gone to bad considering im a complete novice. My stumbling block is my endstops and i dont know were to go in determining how to fix it. I started this project to learn more about electric and laser/cnc machines but now im stuck, so im hoping you knowledgeable lot can help out? K40's meant to home in the top left but the X axis is trying to go the right obviously not finding a endstop so crashing if i let it be, ive jumped the X axis and its still doing the same thing, but i will triple check that again when i get in later. ive also connected the cohesion mini board and that doing the same so am i correct in saying its not the board? I've also wire completely new endstops and their doing the same also? And this is were my knowledge stops and i am stumped, i had problems with the originals ones (jumped them and then they worked as should, so knew it was the optical switches) so i changed them to mechanical stop from optical and that fixed it but now its playing up again and i don't know were to start? At the moment ive put a end stop on the X axis up in the right hand corner and i can now use my laser but its back to front from whats on my screen, to what its burning on my material ! I even fitted mini 3d board with the end stop X axis on the the top right changed the origin point to top in the setting and its works but not quite correctly. If i left it top left in setting on cohesion board the jog option does not work correctly at all. Thanks in advance guys, any more information needed please ask away, i can do videos and pictures if that helps.
