Hi,
I am using a Ruida controller and it seems to be set up in such a way that a dividing or multiplying factor is applied to the Z axis. For that reason I need to be able to change the “Z step per pass” to a higher number, but it seems to be limited to 10 mm. Why is this and can I get passed it in some way?
Thanks!

I don’t have a Z axes, but I know the Ruida has a setting for the Z axes max travel value in the controller.
If this is 10, that will be it’s controllers limit… I don’t know if lightburn reads this value and enforces it or not. I’d suggest you check it for the allowable maximum travel…
Good luck
Hi Jack,
this value currently is set to 650 mm on my Ruida …

Don’t say that around the airport 
I don’t know what else to suggest at this point. Not having a Z axes I have no real experience with it…
Hang in there, someone like @JohnJohn might have something useful to help you out.
If you’re doing multiple passes, you’re probably not needing to move the focal point down more than 10mm each pass. The z-axis behavior is often separate from the X/Y behavior. That’s why it’s hard to not hit the hold-downs.
Interesting… Are you looking at Device Settings in LightBurn or the Ruida control panel?
When you’re connected to the Ruida, and you click Edit, and Get Controller Settings, does the Z step per pass show up in LightBurn.
Please share a pic. I’m very curious.
One of the weird things I see is transposed commas and decimal points. Most of North America reverses the way this is done in Europe.
650mm (well over 2 feet per pass) is unusually large. I would like to see if there’s some
kind of Lead-screw compensation or miscommunication present.
Hi John,
I’m looking at the settings in Lightburn. I’m seeing Step length, is that what you mean? I do see that because of some setting that I need to compensate the Z travel per pass, and then 10 could be too low. But that might be fixed by adjusting another setting. Easiest would be that 1 mm in the software results into 1 mm in physical reality.
Cheers!

How much do you want to move Z per pass for your novel workflow?
What are you hoping or attempting to do?
Hi,
ideal would be that if I enter 1 mm Z travel pas pass, it also in reality would go down 1 mm.
cheers,

How far does it move now? If you tell the Z to move 10mm, does it only move 1mm? If so, you’d need to decrease the ‘Step length’ value for the Z axis by a factor of 10.
Your Z axis likely won’t move 380mm/sec either, or accelerate at the rate it’s set to, so you’ll have to adjust those as well.
