Let me start off by introducing myself. I am a 54-year-old retired Marine with 35 years of automotive repair behind me. I worked for Chrysler/Dodge/Jeep and a couple of older Nascar teams. I love building anything mechanical. My knowledge folder doesn’t hold much but I do have a bachelor’s degree in mechanical engineering. I want to be very clear…I am not the brightest bulb in the batch. (lol)
I have built several 3D printers using Marlin and most recently Klipper firmware. I am familiar with 32-bit boards like skr 1.4 and the octopus pro but I am very new to the older boards. GRBL seems to be easy enough but like I said I am a bit slow.
My problem-
I am currently building a laser engraver based around the Elekslaser style. I want to use a dual Y axis and a single X axis. I purchased the woodpecker CNC board with GRBL 1.1f preinstalled. I am trying to figure out how to power the 2nd Y-axis stepper motor from this board. Can I use the empty Z-axis driver for my 2nd Y-axis motor? I don’t see anything in GRBL about cloning an axis but I may not be understanding it correctly.
Thanks for any help and I hope you all have a GREAT new year.
