I know this is a simple setting, but I’m not getting it. I looked at another post and the solution was what I thought it would be (acceleration) but I change it, write it to the machine and it still does it.
I’ve attached my rotary unit to my machine and I go to frame the test image. It rapids to whatever start position and kicks off the tumbler because it is too fast.
Like I said I changed the acceleration in machine settings (would be “y” axis) and the rollers and the X both rapid to start. I don’t mind the X rapid, but the roller is too fast. Anyone know what I’m missing here?
Also, bonus question, Enable rotary is true in machine settings but unchecked on the laser tab. I assume both need to be checked but why two if they aren’t related?
I use the framing buttons in the move window.
You can specify the speed and slow it down. I also set the angle in the layer so the engrave begins at the same place as i have set the origin so it doesn’t have to jump across the design to start.
Hi, thanks for the response. I’m sorry I’m not sure where the frame in the move window is? I’ve also slowed the speed down in that window and it does nothing for the initial rapid movement to the start position. Also I’m not really sure what changing the angle does, could you help me understand that better? I like the idea of starting where the origin is to get me going for now, but I feel like there is some type of setting that needs to be changed. I would have thought this was the “acceleration” based on everything I see on here and well it just makes sense.
Also @LightBurn I’m still getting the reverse frame once in a while (frame rubber band works like frame boundary and vice versa). Could these be related? Is there something that could be locked in memory somewhere that I could reset somehow? Perhaps I need to uninstall and reinstall?
OK, so now I can get the image to not rapid by setting the origin of the machine to the start position, but when I try and do a material test generator, it still kicks rapids to another position with respect to the rollers. Tried resetting the machine but no help there. And I think that is just some preset in the Material Test generator tab that surpasses the job origin on the laser tab.
I wonder if I connected/disconnected the rotary at the wrong step and this screwed something up internally on the machine. I was getting conflicting info at what point to connect this at and took a chance. Would have thought resetting the machine would solve this problem.
I have an OMTech 1624 with Ruida.
Go to the menus at the top, Select Window. You will see the options.
Select Move. This will open a window that gives you direction and speed options.
set speed for 50mm/s
Now when you use the Laser Frame buttons it will frame slower.
Open the Layer settings and one of the options is scan angle.
Try setting it at something besides zero and it will affect where the engrave starts at.
You can see in the preview window what the results of your change is.
Set that so the engrave starts at the same corner that the origin is and it wont have to jump to begin.
here is what i do for most of my rotary engravings just to be safe. i use a ghost line near the start of the scan direction and parallel. gets the laser head closer to the starting point. run this ghost line at low power like 0,01% and slow ish. also check the cut priority to make sure this line gets done first. you can right click on the line and click shape properties and change the priority to 1 or have it sitting first in the cut layers, double check by playing preview.
You will have to go into the Ruida and slow down the axes.
I noticed your start speeds are pretty fast. I don’t have the machine up, so can’t look… Start speeds work with min/max power values…
On mine the jump off speed is down to a single digit… lower acceleration. I have reduce all the Y axes speeds when using the rotary.
Make sure you save the current configuration and after you modify it, save it for re-loading later for the rotary…
I switch configurations when I use the rotary.
Lower the idle speed, I think it is… one of the first items in the cut menu on the Ruida. This should slow the seek speed at the start of the job…
I hot swap my rotary and have been ever since I got one… However most people frown on this…
If you plug the rotary in, then power up the Ruida will want to do a home operation… does your rotary have home switches on it?
Doubt it… so you have to disable homing on the Y axes… or be quick with the esc key to bail out of the home operation.
If you have a configuration file, like I suggested, you can disable home operations on the Y axes there and write the configuration to the controller… power down plug in rotary and go…
You have to remember to load and write the configuration file… before you power it down, in both situations…
So you create a configuration in the actual controller? DIdn’t realize you could do this. I load Machine settings on Lightburn each time switching to and from a rotary setup, now sounds like I’ll have to create that same type of thing for a rotary condition on the controller as well. Any other settings you change when creating this additional profile on the controller?
Thanks Jack
For every rotary device I have, I have a different machine settings file.
A vector operation on the rotary has substantially different values than an engraving where the item isn’t spinning around back and forth…
A chuck and wheeled rotary, both have different machine settings… the wheeled rotary is more sensitive to acceleration and speeds.
I get them to work, then save them as a machine setting file, named some way so I know what they are. I can read/write to the controller for any of the rotaries I have… Don’t forget to have a normal file, you can reload when going back to normal operations…
When I change operation to a rotary I load then write it to the controller…
You can change any of these, but I usually don’t recommend changing some types of values that are inherently hardware settings…
I have come to the conclusion that the Ruida is an excellent piece of hardware but dumb as a rock… i/o is poorly handled, as you can tell from all the questions… Ethernet is the best and with the Lightburn Bridge it’s even more dependable.
