Just getting my 3000mw Eleksmaker “clone” (500x650 size) with GRBL 1.1h loaded on it working after a debacle of a dead LED. That now fixed, I’m starting some test burns.
Ran into a problem almost immediately.
When I command a Move to (for example) X 20, Y 0, the resulting motion is moving to X 64mm, not to X 20mm.
Likewise, a commanded X 50mm is resulting in a position of X 185mm.
The same ratio is occurring with the Y axis.
Everything is going the correct direction, and the zero points (X and Y) are set fine… it’s just making a “macro” version of the movements.
I must be missing something obvious in the Machine Settings, but I’ve been staring at it for a while now… and I’m still missing it! Suggestions welcomed!
New Steps/mm = (Current steps/mm) x [100 / (measured distance) ]
So have the machine move 100mm and measure the distance it actually travelled and enter it into the formula. This will give you the New or Correct steps/mm to enter in your settings.
Sounds right…
Is that as simple as doing a little division, and adjusting registers $100 and $101, or is there a calibrate function in Lightburn I’m missing?
