Arduino Esplora

Has anyone used an Arduino Esplora as a pendant to control GRBL?
I don't know if it is possible, but it looks interesting.

Re: Z axis motor problem.

The only version .8 that I have been able to find is grbl_v0_8c_atmega328p_16mhz_9600.hex and when I try and use Xloader, it takes forever to send to the board. After sending I am not able to connect, so maybe there is a problem with this hex file?? Are there other 0.8 versions available somewhere f...

Re: Z axis motor problem.

Thanks Bertus,
I will try using version 0.8 and see if there is a difference.

Re: Strange happening when using a laser

GRBL says disconnected. I changed over to a different board that is a genuine UNO and it still happened, I expected that the cloned board with the 340 chip may have been the problem. I then changed over to a different USB port and problem was solved. I have been able to engrave several test pieces w...

Strange happening when using a laser

I have just finished building my second CNC laser. It is using a CNC shield v3 and a Uno 3 running GRBL 0.9h I have it all setup and have been testing it, but part way through a burn test on a small vector file the machine stops and the laser stays on, I have to reset to stop the laser. I have made ...

Z axis motor problem.

New to this board, not used GRBL before, but have a lot of experience with building 3D printers. This one has me stumped. I am using CNC shield 3.0 and GRBL 0.9j I have setup a CNC machine with X Y and Z axis. The Z axis has two steppers driving a M6 lead screw each. I have checked the ref voltage o...

Re: CNC SHIELD Board and Its power to Motors

Have you checked the ref voltage between the small pot on the driver A4988 board and negative? Most of these when purchased are set at about half way or 0.5 volts. If you make a small screw driver from the positive probe of a multimeter and use that to check your ref voltage and adjust at the same t...

Re: Limit switches board V3 GRBL V1.1

I am setting up the same configuration, a CNC shield v3 with GRBL 1.1f I am confused about how to wire the laser module and also use a Z axis with Z limit stop. I want to be able to use the Z axis to raise and lower the laser, but also to be able to control the laser itself. Not sure what connection...
