I am using GT2 belt with 2mm pitch and a 20 tooth idler pulley so that should be a rotation distance of 40 but when I move the head 100mm in klipper it only moves about 80mm in reality

are you using 20t pulleys? Or might you have installed 16t pulleys by accident? (Easy to do on a v2, where there are several of those around for the z drives)

Assuming this is a kit, you'll know for sure when 2 of your z drives have the opposite problem 😛

Thank you for the help!

This is the problem for some reason the y doesn’t home before undocking the probe but the x does

#

I have to assume it think that the y end stop current is reached but I have no idea why that would be different for the homing of y alone and when doing an xyz home

#

The same thing happens when I click the home xy option

Yeah with 2209s

You need to go read the sensorless guide again

#

Basically, when you home the first axis, both 2209s get triggered

#

So you must be missing the step where the macros wait for the diag pin to clear before homing the second axis

Oh I see thank you I will look into that!

#

This is my first killer build and it is a printer that is custom so there is not a huge amount of specific documentation

Sounds like you should have built a voron legacy. Oh wait. That thing doesn't have documentation either 😛

I am a student so a voron anything was a hit out of my price range haha, I bought cheap broken printers and recycled the parts into something that has what I would consider decent performance but does mandate a lot of learning
