Topic: Freelss 1.11 issues.

I finally had some time and resurected my scanner. With that said. The default pins have changed it seems.

I am playing around with this scanner again at this point as the machine is built. But I am noticing these errors. Sometimes its 32 of them other times is 12 or 6 or 1. Any insight? I am not having luck with google.

Merged 16 laser ranges.
numRowsBadFromColor: 0
numRowsBadFromNumRanges: 0
Detected 736 laser pixels.

Re: Freelss 1.11 issues.

Double check the location settings for the lasers and make sure that the x coordinate for the left laser is negative.

Re: Freelss 1.11 issues.

my scanner software came with pin numbers reversed for lasers and I posted this in a couple topics plus told Elmerate per Pirvan suggestion

Solidoodle 2 with Deluxe kit cover & glass bed with heater. and 2nd board SD2 used not 3rd and alum platform not installed yet still wood. also need cooling fan installed to board. use Repetier Host couple vers. Slic3r also have all free ware STL programs

Re: Freelss 1.11 issues.

Well, I massaged it. You were right hairu. The left laser was not negative.

@n2ri, yes the pins have changed a bit. But you can manually change those via the gui. I went through and did just that when I was troubleshooting mine. I am also going to activate a light pin on mine to have the light controlled via the pi. So far my scans have gotten much better.
