Carbide Motion 4

[fshrmn1]

After download and installing ran home and my Z axis went straight down and belt hopped till I shut it Down

Any Ideas why would be appreciated

Did you send the configuration for your machine per http://docs.carbide3d.com/support/carbideupdater/ ?

It probably just means you mounted the Z-axis plate upside down, so the up/down direction for homing needs reversing.

It's pretty simple to do in Carbide Motion. Go to the "MDI" tab and send this command manually:

Code: Select all

/$3=2

That should reverse the travel direction used for the Z-axis.

Saying the above as I did the exact same thing, mounting my Z-axis plate upside down (I did it on purpose though), so also had to make this change.

A more persistent way to make this change is to power down and rewire the stepper motors.

@AnonymousPerson --- may one ask why you did this?

The first time I assembled it, I did it correctly. However the Z-axis springs in my S3 (a reasonably early
model) are so long that they over-compress in the Z-axis homing cycle, thus wouldn't always get to the
top of the axis. eg homing sometimes just failed

When trying to figure out how to fix that problem, I noticed the holes in the Z-axis upgrade plate aren't
centred on the plate. Mounting with the the Z-axis plate upside down gave a bit more clearance, and
the springs don't over compress when the Z-axis moves to the top. Problem solved.

Well, the changed setting gets saved to the board after it's run so doesn't need to get done again unless the settings are reset to their default by something.
