yeah , it just seems to be a script on the server here to save space .
I only restrict by kb on my forums, and they auto thumb nail.

I'm working on the console to have a serial terminal like interface .

I hoe to get started on a X axis for a flatbed scanner i'm overhauling to be just for this laser . it's an old HP that my brother cant use anymore, but the stepper motor inside is just fine .

making bigger dedicated laser bed . This one uses more parts from ando .
( big stepper on top )

got the app where I can send single lines or G Code .
everything in the sys console is sent back to the app from a Arduino Nano .

found a bit of backlash in my y axis.

that's a salvaged DVD diode . it has to go way slower cut through in 1 pass.

made the switch to a violet laser module.

I have tested a fer laser types now , and i like this one only 300mw but the smaller wavelength really helps.

i have got most of the Y axis backlash sorted by adding a tensioner bolt to the belt on the old slack end. i think the backlash is less than a 0.25mm now. i may simply have to account for it in my firmware when it detects a axis direction change.

I may just move to GBRL later too . Edited by Prime_8 2015-05-11
