I have problem with all softwares it doesnt woek even with Gcode sender so I did install the version that you put in Dropbox for and here i attached the files you told him to attach so can you check if you can find anything helpfull? Thanks for reply i bought this device and it is chenesse one called DIY8000 it has CNC and laser mode You can solve preventing electrical noise on wires and buying an original arduino boardĪs workaround with poor clones you can set slower streming mode as suggested in /faq
Poor quality arduino clones can fail showing disconnection, error, hang etc. Good quality ORIGINAL arduino boards can easily withstand the speed with which LaserGRBL communicates with them. This is because LaserGRBL use a very aggessive streaming thread, that is able to stream up to 800 gcode line per second, while other gcode sender are much more slower. The biggest difficulty in understanding this problem was that with other programs like "Universal Gcode Sender" or "SourceRabbit G-Code Sender" he was able to correctly stream the gcode to the machine. Hi can tell you about the experience of a user who had blocks and disconnections of grbl during the early stages of processing, just like you.Īfter many attempts and analysis we have established that the Arduino board in his possession was "defective". You can do a test with an arduino "off-site" or rather detached from your engraver/cnc you can exclude that it is an electrical noise problem (no motor noise).Īnother test could be done using an older version of LaserGRBL that doesn't have ultra fast streaming optimization ( i suggest v2.8.1).

I have tested this with some different board, all having CH340 usb-serial chip, without noticeable problem with grbl 1.1f but I can not ignore the fact that other users have some problems. This result in the ability of stream at 800 gcode line per second: Indeed LaserGRBL has a very fast routine for sending data, of course respecting character-counting protocol, but without adding any extra unneeded delays (sleeping only when no space available in buffer). Both the send-response and the character counting protocols can be used and both have generated errors. This program has streaming code that is very streamlined with nothing extra except what is absolutely necessary for streaming and for detecting GRBL error messages. I say "you have found a good thread" because LaserGRBL streaming thread act in the same way the user explain.Īs further testing, I made a small program to use for testing. However some user report me also the same issue reported on that thread (streaming start and then hang suddenly). $132=200.000 (z max travel, With grbl/grbl#845 you have found a good thread, but the original problem of is a connection problem - not a streaming problem.
It is set by default after installed the latest GRBL on a board. If you don't have any endstop switches, the motor drives against the mechanical limit endless.Ĭheck the GRBL settings in the board. The noise could be a function to drive all axis to the home position. The controller board must run GRBL without any bootloader to avoid thisĪnother way to avoid the problem is switching on the laser after connecting to host.

This has nothing to do with the software here.

The laser goes on to full power because the bootloader in the control board sets all outputs high while running the bootloader routines.Īfter 2 seconds or so, the laser goes off again.
