New to Laser x moves but Y doesnt
« on: August 09, 2019, 01:43:42 PM »
a buddy just bought a low end laser engraver and has asked for my help since ive had my fair share of 3d printers i have built and ran. but i am stumped

this is the kit https://yorahome.com/collections/home-business/products/cnc-laser-engraving-machine-3000mw

i can get it to connect to the pc, i can turn the laser on, get the laser moving left and right(x axis) but i will not move front to back (dual y axis steppers) so i thinks its moving but just gots left to right over and over again...

it told me to use Benbox software which seems very simple

please help

Did you check the current limits on the stepper drivers? The Y axis need twice the current of the X axis. If the drivers were setup by the vendor and you swapped them this would be the expected behavior. For the typical A4998 you should measure a voltage between the trim pot case and ground of approx 0.4V for X and 0.8V for Y. Setting the limits too high will results in excessive heat, too low and missing motion.

It could be a firmware issue, but usually it will only go back when up or down are pressed.
