I’ve spent about eight hours going in circles using my 3.pi burner. When I go to run my program the X access rasters fine but my wheels are not spinning with the program. I tried engraving my term Millertime words on the glass mug with a small rectangle about 3“ x 1“. I did them both as a line and fill. The Y axis just doesn’t wanna move the wheels with the program so that’s very problematic. The wheels turn when it jogs over to the home position hovering over the beer mug. But it doesn’t spin during the program. Is there anything I’m doing wrong? I checked all my settings over and over in the Rotary set up and everything seems fine. When I test in rotary the y wheels do spin and I can manually spin them as well. I also made sure to group the words. Is it a machine setting issue? Any help be great.
It’s 3 am now but customer picks up at 4:40 pm today but they are flexible.
Let me clarify what’s you’ve done, at least during the setup.
How did you come to 9000 steps/rotation? This is a simple setup, might want to ensure you’ve done this.
The test button in Lightburns gui should rotate the driving wheel one complete turn and back.
Assuming you are using the Y axes to drive the rotary?
You’re Y axes acceleration is likely too high. The driving wheels slip if you try to accelerate too quickly. Larger mugs/cups with more mass exacerbate the issue.
Before adjusting anything, ensure you make a backup (saved) copy of the settings from the device settings.
First is to ensure the configuration of the rotary is correct… If so, we may have to look at the controller. I have a 6442g, so they are not the same animal but most of it operates in a very similar manner.
Hello Wilborn, thanks for the reply here. 3200x2.5=8000 So I changed it, tested it saved and resent to the controller and still the Y isn’t moving correctly. I set the acceleration according to Pi manual. I thought it might be to slow and maybe that’s not why it’s moving. I know it’s not a mechanical issue either because when I hit go and it slowly makes its way over to the origin the wheels move but when it engraves they don’t. I checked the gears and tighten down the Allen wrenches and stuff so I do know that that’s all good there. Lmk if you want me to take a pic of my settings or anything to try and problem shoot a little more. I also made sure to plug in the rotary when the machine is turned off, the controller resets the motor and the wheels are turning fine then as well.Its fun when these machines work but man when problems take this long to fix with a deadline it gets nerve racking lol A lot of people are on their own with these Chinese machines, if you happen to know another resource for some sort of service tech over the phone please let me know. I can share my contact # my number and Venmo people if they can provide a solution.
Is the 3200 from your stepper motor driver? I’d suggest you go back to the actual value. Your 9000 seems too far off to be correct. Remember it’s a digital system… It either correct or it fails, at least to the motor. It becomes analog at the pulley/belt drive… That shouldn’t be off that much.
If it comes down to it, this guy has helped a number of people… he’s down under (AU) and I don’t know what he charges.
Hi, yes it has always worked. When I initially set up the rotary it said 3200 and that was what was in the original setting but still didn’t work so I changed it. Like I don’t think stepper motors manually change on their own but maybe that’s what I have to do is start over all the way from the very beginning of setting my stepper motors again again?
Last night, I unplugged the machine and plug the Y access in and did a regular rest rising and everything works fine. I did have to go back to my original settings because the pi settings are much slower. I mean there was a 15 sec delay before the head would move into the origin position over the mug. Maybe their settings from the pdf manual were too slow for my machine and that somehow messed up the y movement? I hope I figure this one out because I will be documenting the set up (when it works) and etching the directions on my arm so it’s unforgettable… lol
