with Core 2.0.03.
I use the fabric enclosure from Ortur and 24-mm nGen standoffs for the legs. When I cut a grille consisting of some 1,000+ 2-mm holes, the frame was shaking in the enclosure so badly that the symmetrical array of holes did not come out at all symmetrical. I reckon I could either replace the nGen standoffs with something that has more friction, apply a high-friction tape at the bottom of the standoffs, or reduce the non-output travel move acceleration and speed.
How do I reduce the non-output travel move speed and non-output travel acceleration?
Do you have other great suggestions on what I could do to output the project correctly?
Turn off Fast Whitespace Scan in the Device Settings window, or reduce the speed. Controlling the acceleration setting requires changing a GRBL parameter in the controller.
Put double-sided sticky tape under the feet of the laser. Warning: This might make the table it is sitting on wiggle.
If the laser frame is flexing, make sure all the srews are tight or just slow everything down. I would not consider 300mm/m all that fast. I just did a dry run (0.5% power) with my SF-A9 40w (massive module) on 6" legs. It did not move at all (feet are blocked in place).
Thank you. I will adjust the fast whitespace scan setting tomorrow once I’m back at the frame.
To clarify a little: the table itself is wobbly but the frame and enclosure seem to stay stationary with respect to the table. I’m going to shorten the legs on the table to reduce wobble.
The frame of the laser is rigid and not flexing. Instead, it was hopping in the enclosure. This became blatantly apparent when I increased the speed to 20,000 which is the absurd (must be a typo) speed that Ortur suggests for my module, LU2-10A, for poplar sheets when engraving.
But after posting what I posted, I realised that the stock legs have a rubber/TPU/something padding on them to increase friction, and nGen, on the other hand, is notoriously smooth and frictionless, so I also removed the standoffs for now.
