Shaking Problem On My Laser Pointer

Postby Matthewbeli » Thu Oct 27, 2016 1:50 am

Hello
I just bought this Laser/Engraving Machine
I used 2 days and everything was perfect
Today when it was cutting it started to shake when the Y axis try to move.
Its not moving at all.

Belt too tight or too loose?

IIRC, it should only move up and down 10-20mm.

Can't tell much from the video but my best guess would be the belts jumping teeth, if not then I'd suspect a driver card. If possible switch the X & Y driver cards round to test if the same problem occurs. If it swaps from X to Y then its likely a card or a stepper, if it doesn't then it's the belt jumping.
Tension looks ok, flatbeds do tend to have a bit more slack due to the length of the belt but my second best guess would be a physical blockage jamming the gantry causing the belt to jump.

On second look, i'd look at the gantry angle, if the belt has jumped then it will be trying to pull the gantry along at a crab angle.

I very glad about your message. Im thinking about the driver problem because when I tried to move the x and y axis with my hand without turn on the machine it works ok to backward to forward but when I try to do the same process with the arrows on the panel Y axis start to shake and do go anywhere . I guess some of the cables plug out from its of place or completly Y axis driver has a problem tomorrow I will check out the cables on the Driver

What type of motors are being used? Steppers or servos?

Normally if one wire it not connected properly to a stepper the stepper will judder instead of run. Take the belt off and check if the stepper moved smoothly then try to load it up a bit using your fingers.
