    I was just reading about how the execution speed of Java programs will improve over time as frequently called methods are compiled and optimized by the JIT compiler.

    This might explain why my problems go away after a few runs.

    I finally had a chance to test with my new cable last night and I don’t think it made a difference. I did, however, make some interesting observations.

    First, I noticed that the problem seems to get better when I run the file for a second time and is generally gone by the third run. If I close and re-start tgFX the problem re-appears. I repeated this twice but I’ll probably try one more time to make sure it’s really repeatable.

    Second, I noticed an error in the tgFX console that generally appears during the first run. I have no idea what causes it or if it’s directly related but it usually doesn’t happen after the first run.

    I should mention a few changes that may have caused the problem to re-appear:

    – I switched the motors for the x and y axes to high-power idle
    – I incrementally reduced the speed from 33.3 in/min down to 10.0 in/min

    I’ve ordered a nice USB cable to see if that makes any difference. I’ve been using a collection of flimsy cables that came with various cameras and phones over the years.

    It seemed to be running fine so I decided to try turning on the router. I moved everything to the garage and I got this:

    I moved everything back inside and now I get this:

    I was able to get tgFX running on my windows machine and I think that may have fixed my problem.

    Thanks for taking the time to look at it. I’ll try to get a video or picture uploaded this weekend.

    It does most of the arc on the top of the n but instead of doing the vertical line is reverses direction and does part of a small circle. Eventually it skips the rest of the n and goes to the dot on the top of the i.

    Are there instructions somewhere for using tgFX on Windows?

    Last night I was noticing that my gcode file (generated with HeeksCNC) is rather verbose compared to the ‘Hello World Shapeoko’ file. I’m going to try cleaning it up to see if that helps.

    What operating systems are most people using? I’ve seen a lot of references to mac’s. Is there any chance that Windows has some latency issues that cause problems with the flow control? I’d like to try adjusting the high-water-mark for the receive buffer but I guess I’ll have to purchase a programmer first.
