  Agree not sure where I can go from here except to compare the parameters between the two versions. I would certainly like to keep the Z homing for sure. I'll try turning the laser right down so it it simply draws on paper and see if I can see the difference that way. But the movement is very noticeable on the curves.

  @tucker298 Yes, plug and play. The boot loader should be pre-installed, the only Nano's I've purchased where this wasn't the case were the unsoldered bulk variety (but for less than $1 each I wasn't bothered).

  @pietro78 Checked the DXF with several other programs, T2Laser is loading it correctly. The problem must be with the export, suggested loading it back in to AutoCAD to see what size it shows.

  Yep, it's working fine and a very useful addition. Certainly saves fiddling with the lens focus every time the project height changes.

  Cheers

  @magictoolbox I'm not sure what you are saying, are the files not loading correctly or there is a problem with the laser output? You can check the simulation "view" to see exactly what is output to determine if it's a laser issue or not.

  It actually sounds like the laser is failing when it gets hot, but please upload pictures or send your question to support@t2laser.org email.

  Jethro, just a thought that you can try as a last resort. I had a similar issue on my A5, I couldn't get it to burn a perfect circle, the ends would never meet and figures would have a distinct pattern anomaly across them. I also noticed that if I moved the laser by hand, it felt like there was a bump in the rail or a flat spot on the wheels. It turned out that I had one of my belts too tight. Once I loosened it just a tad, everything began working much better. It's the simple things that drive me crazy.

  @grant-gibson If you can find the center, then select Center (Start Point) in the settings and then Set Origin (Workpiece) in the center of your item. You would jog to the center and then right click the house "home" icon and your coordinates will change to 0,0.

  I use this for round items as it's difficult to find the lower left corner, but if I want it precise or plan to make multiple items I will load a DXF of the correct size and make a jig from foam. Then you just put the item into the jig, of course I have home switches and use the preset locations for the jigs so it makes it even easier.

  @edwawr Yes, you must focus the laser or it won't have enough power to burn.

  @Bor Yes, that's calculated and handled automatically in the rotary setup screen.

  @Bor I think you are asking about the "drag chains", they're cheap on banggood or aliexpress. You can probably get them from ebay too.

  @Zak Easel is an online software created by Inventables. You can check it out here http://easel.inventables.com

  You're right about it not making sense, so I tried resetting everything again and managed to get it working! Something must have gotten changed in the defaults as you mentioned. Not sure why it didn't work the first time I did the reset.

  Thanks for your help in problem solving this!

  @Zax Ok, weird stuff...
  The Z axis was stalling regularly during the 10mm square test when I started trying some $112 and $122 values. 200 for both and all was good. Gradually increased $112 to 5000 (max) leaving Accel at 200. All was good with $112=5000. Started to raise the accel value in 1000 increments, expecting it to fail at 5000, But NO! it worked fine with $122=5000.
  So whether the stored value was corrupted at some point back in the beginning when I was installing the s/w or firmware who knows. All the time in display grbl parameters the Z accel showed as 5000mm/sec^2, so probably never know. Anyway, I have set $112=5000, and $122=1000 just to be on the safe side and all is well.
  Still need to stop it doing all the return to Z0, but at least it is working now.
  BTW, I had tried loading default parameters before, but it still didn't work, so who knows why it is now!

  Thanks Zax for pointing me at the debug mode!

  Cheers

  David

  @modellermark2 No, EleksCAM is older software and doesn’t support Grbl 1.1 but don’t worry, T2Laser does everything better

  There are some posts on adding home switches, in T2Laser you just enable it in the settings menu and it’s automatic.

  I’m away for the holiday weekend so don’t have access to my pictures or notes but if you email me I can send you details.

  @newfreedom The laser is getting hot?

  That’s not normal, the current limit is preset on the driver.
