    Hi – I’m having an issue with large curvy projects in tgfx / tinyg, using a laser, where the work will pause – tgfx shows there is movement but the motors just hang while the laser burns a darker spot than it should. Is this caused by overloading the processor or some kind of buffering issue?

    Here’s a video of it happening, sort of – it can be worse than what I recorded here: https://www.youtube.com/watch?v=igH4Mysga5E

    Here’s a pic of the results, where you can see the uneven burn spots where the tinyg just stops to think or catch up on the queue:

    We need a whole lot more information to be of any help.
    tinyG FW version installed (Build = ?) ?
    txFX running (Build = ?) ?

    Sure – thanks for reply. Have a fairly recent fw upgrade and windows app.
    From the $$:

    [fb] firmware build 435.10
    [fv] firmware version 0.97
    [hp] hardware platform 1.00
    [hv] hardware version 8.00

    and using tgFX_windows – rc1- x86 x64 build 3625 – v0.97

    Here’s the dropbox link:

    and in there’s the recently troublesome nc file and the full $$ dump.

    On the road at the moment, will give a harder look in 24 hrs.

    I suggest you move to tinyG fw 438.02 (current edge)and give it a try.

    Actually it’s starting to look like the issue s with tgFX – just found a long job going into LOONG pauses, and when I hit ‘pause’ on the gcode program panel the motors stopped mmediately, but the display and position indcators continued to update – like they were catching up – for some time, then when I hit ‘resume’ it continued w/o problem, until of course they get out of sync again. My notebook cpu is near maxed out so ‘ll try closing some things.

    Yes – problem solved, was running out of resources on the notebook runnng tgFX – gotta remember this *is* java 😉 – it’ll use up 50% cpu on an Intel Core2 Duo T6500 @2.10GHz. As long as I shut enough down everything is workng fine on an ultra-long (52 minutes so far at 75mm / sec) laser cut.

    🙂

    Good news that something works, but I am not at all certain what it is that is working:

    You are running tgFX build 3625.
    Did you update to tinyG 438.02, or stay with 435.10?

    It is possible that communication/flow control issues are at play if you stayed with 435.10. tgFX was the outgrowth of tweaks to make tinyG 438.02 and tgFX cooperate well

    Resource issues are incredibly hard to understand, but I will comment that I have seen tgFX run ‘OK’ (whatever that means) with CPU pegged at 100%.

    I quickly ran your .nc in a simulator; nothing immediately obvious.

    Sure – Indeed after the hour long laser cut I noticed the piece finished and tgFX was still drawing and reporting movement for another, maybe 30 seconds.

    Well, I downloaded this: http://synthetos.github.io/binaries/tinyg-edge-438.02.hex

    Just now loaded 438.02.hex but had to use avrdude – could not load from tgfx (below), maybe it does not know where avrdude is.

    C:\Users\chuck\Downloads\arduino-1.0-windows\arduino-1.0\hardware\tools\avr\bin>avrdude -p x192a3 -c
    avr109 -b 115200 -P COM29 -U flash:w:tinyg-edge-438.02.hex

    avrdude done. Thank you.

    Prevously tred to upgrade from tgFX, machine settings, update firmware from file, the console reports:

    Your TinyG will start blinking rapidly while being programmed

    Updating TinyG Now… Please Wait
    Attempting to update TinyG’s firmware.
    Attempting to reconnecto to TinyG…
    Firmware update complete.

    Yes, others have reported that tgFX build 3625has issues with doing tinyG updates.

    Happy cutting, errr, lasing.
