Thank you! I seem to be making some progress today. I got all three to home properly finally. Still some strange behavior though. Once I home Y it doesn't want to move after that when you bump it with the manual movement control. One day at a time I guess. At least everything is moving the correct way and actually stopping when it hits the switch.

Really? Of course I read the build guide! It's 100% box stock right off the BOM. the only thing I changed was the Duet Wifi. I've also read the Duet Wifi documentation. I guess I should apologize for not fully understanding everything in Duet's docs. I'll also apologize for my less than perfect attitude, my frustration level is high at the moment and Duet support telling me just to read the docs and figure it out on my own doesn't help.

I'm officially at a 100% loss of what to do next. I went through the configuration app as suggested and answered everything to the best of my ability for a CoreXY. Now it's even worse than before. X is Y and Y is X. End stops aren't behaving properly and Z motors chatter and grind like crazy. I don't know what the problem is and I literally don't have a clue where to start to fix it. I guess it just me…

Doug, I totally understand what you are saying. However, I imagine a lot of new comers by these boards such as myself, the docs are great but some don't yet fully understand all the terminology and how it applies. Newbies are part of the game if you are selling products, especially relatively expensive and technical products. There's nothing more a customer hates to hear when trying to get help is just read the directions.

For example, Simplify 3D has dozens of profiles setup for all different kinds of printers just to get you started in the right direction while you are learning the software and all of it's configuration possibilities. $150. Duet Wifi $170… just read the directions?

Again, I get it what you are saying, but...

Let's start here.

What do you mean by are the switches on the high end or the low end? Are they taking about the top or the bottom of the printer?

Thanks for the help. Guess I'm on my own to figure it all out. I feel much better now that I have links to the documentation though, didn't see those before. I'm new to this and a little frustrated at this point, telling me to read the docs isn't much help.

Here's a couple specific questions. 1. I don't know if my switches are normally closed or open. 2. What do you mean by are the switches on the high end or the low end? Are they taking about the top or the bottom of the printer?

Having a heck of a time getting this configured for the D-Bot. It's a stock build right off the BOM so the Y and Z end stops are on the back right top corner.

Here's my issue homing one axis at a time.

X homes ok. When X triggers the switch it backs off the in opposite direction a mm or two almost like a little bounce. Looks like it's operating just like it should.

Z moves down then up about 10mm from wherever it's sitting and stops by itself. Never touches the switch.

When Y triggers, it goes to back off like X does and it goes the wrong way pushing it further into the switch.

Can someone possibly help me sort out my config files? Configuring this thing is a real mind bender for me.

Can someone help me with how this should be wired to the Duet Wifi. Not sure the pinouts are correct.
