I rewired my system for the Dual Endstops. I am on a RAMBO 1.4 from Ryan.
All is working slick except for the output of E0 (AKA X2). Which even stepper is connected to that output, it sorta vibrates and does not move right. The Other 3 X, Y, and Y2 all output quiet smooth movement to the motors.
If I use the X motor into the X2 port, then that motor acts bizzare.
I looked through teh Source code and all teh settings for X match X2 for current and such. Do I have a bumb board? (never used the E0 output till this mod.
Two things to try, swap the cables and swap the steppers. Easy to do with your belts off. See if it follows the driver, the extender, or the stepper. There has only been one board issue so far and it was a mini, chances are pretty good it is something else. Not saying it can’t happen but the other stuff takes two minutes to check.
Which ever firmware it is also try the other as well. Just to rule out a screw up on my part. I am done for the night, I will double check the driver current in the morning. I am not sure I adjusted all of them…or at least I don’t remember checking it yesterday.
If ultimmachine has somehow prevented that from popping a driver I am going to send them a thank you note tomorrow. I know they have prevented back current from basics manual movements but I didn’t think from a powered disconnect.
I ran it on my machine, all steppers have what seems like equal power. I am going to try a separate set of steppes just to be 100%, after the mail run.
If you feel it’s OK, then send it back with my KIT order, so I have spares. I just paid for a full RAMBo kit and the works, so I will have extra parts. I am hating this downtime, this system is too much fun. another $300+ to have full spares is worth it
