i recently acquired a very old laser cutter that had its original laser removed. This machine came with a serial port input system, which i am trying to upgrade it with a smoothieboard.
i have removed all of the old boards and have the smoothieboard wired in for testing,
Problem 1 i am having:
stepper movement seems to move at the correct speed sometimes, but once in a while it would crawl the +/- 100mm
how i am doing the testing:
using laserweb4 / pronterface controlling the movements +/-100mm on X/Y axis
when i click home axis it does nothing.
i thought this was because i didnt have my endstops connected, but even with end stops connected. the axis doesnt move.
i have checked that end stops are working properly with the m119 command.
when end stops arent clicked i get X:0 Y: 0 Z:0 when clicked. i get X:1 Y: 1 Z:0
Sometimes i get cant write to printer errors. serial exception: write timeout
Not sure what is going on here.
Thanks for your help
