Ive been toying with the idea of replacing my Y axis steppas with nema 23’s rather than 17 for more grunt.
Thats the easy bit…
Now comes the complex section.
Im already running dual ends on X and Y
Now im looking to add an additional set of end stops to the back end of the X Gantry.
This is to the facilatate Quad dual end stops on x all setting X Min and 2 X max
Once i can get these working on spare GPIO pins i am looking at adding a 2nd X /Z gantry !!!
This would be parked at the right when using the First Gantry and Z axis. Then on a tool change it fires a bank of relays to then enable the 2nd gantry with 2nd Z axis.
This would then home against the back of the first gantry that would be parked to the extreme left.
As i know the distance between them i can then zero in the 2nd gantry at a known point in space and carry on the Job now with a complacently different tool.
Then when done i can switch back to first gantry by homing gantry 2 to the right again , relays fire etc now you have the other gantry back in play.
Hopefully that makes sence any thought appreciated.
Am i mad to even consider attempting this?
