Apologies if this is a redundant question, but I have been trying to read around this issue and have been getting myself confused. I have an upgraded shapeoko 2 (now x-carve) and am still running the 0.8v of Grbl that came preloaded onto my electronics.
I have been reading around the literature in grbl v0.9 and believe the stability fixes will alleviate some of the issues I have periodically had throughout my cnc journey! However, I am somewhat baffled as to how I go about updating (reflashing?) my current version of grbl to the newer output.
I have been onto the Github website an tried to make sense of the procedure but am still a bit unsure as to what I have to do. Is there, or can anyone give me a step by step process I need to follow?
whenever i have tried to download the relevant hex file (though clicking the appropriate link) it just opens a window in safari with a series of numbers, rather than instigating a download.
These are all the files basically you need.
I included X-Loader also in case you need it.
There is a trick to load this files, I’m looking for. Just give me a little time.
Go to File - Examples - EEPROM - eeprom_clear
Click it,
Find this line,
for ( int i = 0 ; i < EEPROM.length() ; i++ )
MUST BE CHANGED TO
for ( int i = 0 ; i < 1024; i++ )
After upload finish, close Arduino IDE, open XLoader , Make sure all your settings are correct
Device = Uno(ATmega328)
Baud rate 115200
Load HEX file name = grbl0_9i_X_Carve_500mm_ACME.hex
Close XLoader and start Easel, run machine setup.
There is newer grbl hex now people trying to load, didn’t work yet. I suggest you stick with 0.9i for now.
Don’t forget to run Machine Setup on Easel. This is one time deal, specifically for your machine. If you have further problems, let us know.
Fantastic, thanks Alan. I notice the Hex file has ACME in the name, I am running the traditional threaded rod… will that be an issue or can I reconfigure post update.
No problem, also saying 500, that’s way I’m asking you to run Machine setup and give all proper information. The other two .pp files are Post Processor files. If your tool path generator (VCarve/Aspire ETC.) requires, you have to put those files into PostProcessors folder. I have already modified those for Spindle On/Off, Job End.
Right, I am about to give it a go… I have gathered that I need to use Mac OS X Hex loader instead of the x loader which is for windows.
Before I start, am I right in using the hex file you sent me (Alan), or should I be using the “Grbl v0.9i Atmega328p 16mhz 115200baud with ShapeOko2 defaults.hex” from github. I am only asking as I am still using the ShapeOko2 defaults
Sorry I sent message to several guys, didn’t receive any answer back. I think you can use defaults then run Machine setup to see if corrects the parameters. You can’t pass machine setup if it doesn’t like it anyway.
I could NOT get the HEX file to work.
I could NOT get the Grbl Upload example to compile.
It turns out that the files need to be included for it to compile / load were not being added to the library automatically like they should. I manually added the grbl folder with all the necessary .h files to the Arduino Library folder on my PC (I found the path in the software’s settings)
Once I did that the Grbl Upload example compiled and uploaded correctly.
