Carbide Motion 4

Post by fshrmn1 » Sat Mar 03, 2018 3:26 pm

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.
