So I have been cutting some foam and the back of the laser is moving the material , It looks like that part of the back of the laser might be tilted just a bit.
Is there an adjustment or hack as i just need a mm or 2 cutting material is just below 1/4 inch
I was able to push down on the honey comb just a tiny bit but feel that its off on one corner.
That fan is the air assist that keeps the cutting area clear and can’t be moved.
Is your material over 1/2”? If so you will need to remove the crumb tray as advised above. Also, have you checked that your crumb tray is in the dimples below it’s feet? Sometimes gunk can get in those dimples and lift the tray somewhat.
When you’re cutting anything taller than proofgrade, you can test for clearance. Turn off the power and gently move the head around. If the air as ssust scrapes, you need a new approach.
There should be 1/2" of clearance between your crumb tray and the air assist. If it’s hitting 1/4" material that’s flat against the tray, something’s off, but the fan being at the wrong angle is one of the last things I would suspect.
In addition to the suggestions already made above, I would say make sure your foam is fastened down to the tray so it can’t lift when air blows it. You can use thin magnets or Honeycomb bed holdown pins.
There should be virtually no give in the honeycomb, except a slight wiggle going front to back. Are you sure that all four feet are in the dimples in the bottom of your machine? If they are, then how level is the table that you’re using? Aside from the first, have you had any other issues with the proofgrade?
I’d assume foam is light enough that the air assist could get under it and raise it while the machine is running, so if none of the above is your problem, I’d also suggest using something to “pin” it down. Magnets are great because they don’t need to be that big, and the pins that geek2nurse mentioned are amazing for general use.
The fan absolutely should NOT be touching 1/4" thick material, there is 1/2" clearance between the fan and the honeycomb.
The fan will, however, blow lightweight materials (or even small pieces of heavier materials) around the honeycomb tray if they’re not held in place somehow.
If the tray rocks a little bit, make sure the feet are fully seated in the dimples, make sure there is no debris in the bottom under the tray, and make sure the table the GF is on, is totally flat.
“banged my head on the desk multiple times as I began working through the early growing pains of learning Inkscape, spent hours repeatedly crashing the software trying to make complex bitmaps into vectors and then destroying them in the process of trying to fit them within the rectangle of the MBP template and chop off the overlapping bits without using masks, and then doing test runs on cardboard only to find they weren’t good enough to satisfy me.”
Now I understand you pushing me so hard to learn the Vector AI, thank you for your gallant efforts it has been noted as I start my vector journey.
