Can't move the z axis in DWC more than 200

[luka1952]

Hi, Strangly i can't move z axis on my hypercube more than 200 in DWC. The z axis limit is 390. And before it was working ok.
What can cause this?
Is my board damaged?

[Phaedrux]

Please share your config.g, homing files, bed.g, etc
Also the results of M122 and M98 P"config.g"
This will give us an idea of what is happening.

When you say it won't move more than 200mm, what happens when it stops? What sequence of events is happening to lead up to this? Is it possible the Z axis is binding?

@phaedrux
Thanks for reply. This are my files you asked about.
When my print has finished I wanted to juggle the bed down to remove it easer. I hit +50 on z axis in DWC (the part I printed was 180mm high) so the bed supposed to move 50mm down. But it stops at 200 and refuse to lower further. I repeated the command seweral times. But didn't work. Then I moved up a bit and try to lower it again. But still the same. Stops at 200.

@luka1952 M98 P"config.g" shows your issue:

Error: Z axis maximum must be greater than minimum
Error: Z axis maximum must be greater than minimum

; Axis Limits
M208 X0 Y0 Z0:0 S1 ; set axis minima
M208 X390 Y375 Z390:390 S0 ; set axis maxima

You have put in a double value for Z for both min and max. There should be only one value in both. My guess is that it fails to interpret this and so retains the default limits (zmax 200).

Change it to

; Axis Limits
M208 X0 Y0 Z0 S1 ; set axis minima
M208 X390 Y375 Z390 S0 ; set axis maxima

Same applies to all your other settings (steps, microsteps currents, accel, jerk, max speed). RRF only support one value per axis for each of these (apart from extruders)

[luka1952]

@engikeneer
I have dubbele z axis with two independent steppers/drivers.
This make possible to adjust the two z axis screws apart from each other.

[engikeneer]

@luka1952 but they are one axis. If they were different, it just wouldn't work. They can't have different limits, acceleration rates etc if they move together as one axis.

I say again, RRF only supports one value per axis for each of these (apart from extruders)

[luka1952]

@engikeneer
Thanks, I've changed it and it works
Thank you very much.
There is one more problem I have but that's in the other topic. Could you have a look? I can't solve it...
