General Mach Discussion / Correcting Step error
« on: February 25, 2011, 07:49:06 PM »
I am a newbie to this stuff and have a Made in chin-o laser engraver (jinjan?). Most of the posts I see have to do with loosing steps. Yes I had this problem too as a result of the machine unable to reach top speed.

However the problem I have is GAINING steps or length. I cut a line 10" long and it come out 10.075 are there any adjustments I can do? I use newlydraw.
the machine is much better in one direction than the other If you consider the "scan direction" head moves back and forth as the x axis and the other the Y axis the error in the x direction is +.030 in 10" and + .075 in the y direction. it appears the gear/step ratio is off.

Suggestions? Some on also mentioned a different board that could be dropped in so I could use mach 3. What boards will work.
