Re: dissable Z limit?

I made a discovery that I am using and may be helpful to others. I downloaded the latest version of LaserGRBL and within that program under tools, are able to flash a new GRBL onto your Arduino. Amongst the selections is a version of GRBL 1.1h (latest version) that has no Z, so after flashing mine I...

Re: Y-axis motors not running in sync

Problem fixed. Found that the plug itto the motor driver had a bad connection. Luckily I didn't blow the driver. Refitted the connection and now it is working OK, the problem was that one motor wasn't working at all and the other motor was doing all the driving.

Y-axis motors not running in sync

I am having a bit of a problem and can't work out how to fix it or what is causing it. I have built a laser and have a strange problem that has developed. The bed is wide 1500mm so i used two stepper motors, one at either side. i have cloned the A on the CNC shield to be the second Y motor. The move...

dissable Z limit?

I have built a laser engraver for a friend and am setting it up now. I have run into a problem that I can't sort out and need some help please. The machine has only X and Y, no Z movement. I have put the laser control onto Z- limit pin on the CNC shield board and have put a LED on that pin for testi...

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...
