PLEXIGLAS GS arancione 2C4 è disponibile presso PLEXIGLAS . Qui https://www.plattenzuschnitt24.de/Acrylglas-GS-orange-3mm.html o direttamente dal produttore. Non posso dirti se protegge al 100%. Ho fatto diversi test e ho bombardato il plexiglass direttamente con il laser. Penetra solo dopo un periodo di tempo più lungo solo in un luogo (con il vetro acrilico trasparente passa senza ostacoli). Se si lavora con materiali leggermente riflettenti, è necessario indossare anche gli occhiali.
PLEXIGLAS GS orange 2C4 is available from PLEXIGLAS . Either here https://www.plattenzuschnitt24.de/Acrylglas-GS-orange-3mm.html or directly from the manufacturer. I can't tell you if it protects 100%. I did several tests and bombarded the plexiglass directly with the laser. It penetrates only after longer time on a place only (with clear acrylic glass it goes unhindered through). If you work with slightly reflective materials, you should also put on the glasses.
@nottingham82 I have the problem where the 4 wheels for the z axis are too tight, this makes the rotar stuck when it has to laser small objects because there is not enough speed to get over the miniscule bumps on the metal bar in which the wheels are rolling. Are there any known fixes for this? Or should I just use a file to make the screw holes a bit bigger, so the wheels are less tight to each other?
This simple configurations i know, problem is not the port. ill notice problem is my mana ardiono board.
did know how to Full reset firmware ? i think it might be recovered, i don't know what is actually happened. when i power On lacer it always ON note moving X,Y,Z moters. please help me..
RST ROM is how to firmware reset.
You not select PORT as I show in picture. When you not select PORT and give power to laser board laser go full power.
Problem is you not select port to connect laser to computer.
As I see - you use SVG files directly intended use with EggBot™. First thing - they a in pixel measures, not in millimeters. But that knowledge is also useless as EleksCAM did not render some SVG files correctly.
I mounted two microswitches, one on the end of the X axis rail, set so that when the laser mount moves fully to the left it closes the switch, the other on the left front (nearest to the side with the control circuit) set so that when the X axis rail moves to the front it closes that switch.
Both switches are connected in parallel, (common pins together and normally open pins together) then one set of contacts is soldered to pin D9 on the arduino the other to the ground connection. Set T2 Laser, control laser, settings, select "Home Switches" and that's it. (I fixed the switches in place with very strong double sided tape, works well but would probably be better to use nuts and bolts!)
@JimWrey I have several softwares installed. I only use T2 to operate my machines though. Personal preference is part of it. Community support is the other part. Zax helped me get my laser going last year. Since then if I have had a question or suggestion I get almost instantaneous (or within a day) feedback from other t2 users or zax. Its best not to software hop. They will all work but they take time to learn. When you feel you have hit the limitations of one software, try another. I tried Lightburn. I liked it but it has no firmware and it cant support rotary axis. Those are 2 things I have to have so I stick with the software that does the things I need and that is T2.
Had trouble assembling the pen holder as described in the instructions so I designed/printed my own with a 3D printer. Much sturdier and only requires 3 new parts and a couple more M3 screws. You can download and print your own here... https://www.thingiverse.com/thing:2781561
I had a similar issue so I added 4 1/32 flat nylon washers so that the there was a smooth yet tight surface that allowed the wheels to spin, Other wise the wheels were dragging and some places the belt would slip. This immediately solved my problem. If you look at the X axis it has spacers on each side if the wheels but the Y axis does not so the nylon flat washers add that. It worked for me, not smooth as glass.
