If everything checks out systems wise, you might just be going at it too aggressively. If it’s that intricate, it will never get up to that speed anyways. A speed setting of 285 will be half of 485; I’d try that and 50 power.
cutting magnetic sheeting… and I just tightened the tension on the left and right belts using that rear wheel, pushing it rearward a hair and retightening the screw. Seems like that MAYBE helped 20% or so. But there’s still a thud or clunking sound on forward and backward movements. I dont want to bandaid fix it by dropping the speed and power. I might have to since I have orders to fulfill but this is something that is recent. Almost around the time GF upgraded the speed and power settings. I had to reconfigure some stuff.
SO is it possible that nothing is wrong with the machine but my settings are just out of it’s abilities?
Didn’t know we could cut magnetic sheeting with this.
The magnet might actually be pulling on the head and causing it to bobble at the higher speed with a sudden stop…you might want to watch one of the prints very closely, and see if you see movement on the head when it comes to a sudden stop or change of direction.
Or maybe support will have an idea for you to try.
Try a different material with same settings. If it works fine, then it’s the material your using.
If it still has the issue, the try slower speed with higher power. If it’s still and issue, then it’s the machine itself and not material or settings.
Process of elimination.
Yeah it’s not the material. Tried oil board for a stencil and same problem. Lower speeds still have that bucking or clunking sound and are bumping the machine enough that I can feel it. Are the two wheels on the right rails supposed to be loose? If I pick up the arm a millimeter, I can wiggle the wheels left and right about an 1/8”. Both. Left side is tight.
If anyone can open their GF and wiggle the whole arm/tube/head thing just a little bit, like you’re moving bicycle handle bars, I’d like to know if yours is loose too.
Each moving part has a plate that the wheels mount on (one on each side for the gantry, and the carriage plate for the head). Grab them securely and see if you can get any play in the belts that they are attached to. Also try moving the gantry in relation to each side plate - hold each one securely against the side rail, and try wiggling the gantry to see if there’s any play there.
I get the most play in the whole arm, it can move like bicycle handlebars turning left/right. Not much, but seems wrong. Pulleys have been removed and tightened. Belts seem fine tension wise. The two top track wheels on the right of the arm can move side to side on their bolt. Shouldn’t they be tight but free spinning?
Oh no! I’m so sorry you’ve hit a snag. Would it be possible to get some photos of the prints experiencing bucking or skipping you’ve described?
Additionally, I’d like you to perform a standardized print for us to review. Seeing the print results will allow us to suggest the best next steps. At your earliest convenience, please perform the following:
thanks! But I think I’ve figured out the issue. I know troubleshooting always starts at step one, but I’m beyond that and in a hurry. Can you tell me if the small plastic wheels attached to the arm and that run on the top of the side rails should have any play in them? The screws that hold them in are tight BUT the wheels can move in and out on the bolt/shaft that they spin on. Are there bearings in there that could go bad?
Hi @TypicalAdamo! Thank you for the reply. My apologies about the delay in getting back to you. Typically the wheels on the laser arm are not a source of trouble unless one is cracked or visibly damaged. Based on your description, that seems unlikely to be the source of the issue here. I’ll need some more information before I can advise about the next steps.
Could you please tell me more about the trouble you’ve been experiencing? If possible, please post a short video of what you are seeing.
Could you please also let me know, have you had any prints that didn’t turn out as expected?
