Hi, Once I had assembled the unit, I found that the lead screw had a bend in it. It has been replaced with a new one. I installed the Interface and got the gantry moving. I found that I need to calibrate the Interface. I put a mark on the rail and zeroed the 'X' axis moved a certain amount using the DRO on the interface. The distance moved was much farther than the DRO said it should be. How do I calibrate the interface? I see that the program has a way to do it. But, I will be using the interface to control the gantry's movement since the computer runs the CNC Mill. Do I setup all the calibrations in the openbuilds software and then download it into the Interface along with the G-Code? Thanks, Joe Casalino
Hi Joe, the calibration involves changing the GRBL settings which are saved in the BlackBox. Cheers Gary
Gary, thanks. Let me review this.With the openbuilds software on my computer, I use a USB cable to connect it to the Black Box, which is interfaces with the motor. I can then program the limit switches, calibrations, etc.into the Black box. From that point on, I use the interface, plugged into the black box, to control the motor. In this way, on my computer, I can have both the Openbuilds software on it, to reprogram the Black Box and CNC software to control the mill. Thanks, Joe
CONTROL does both that. See the Software section of docs.openbuilds.com for an overview of the CAD>CAM>CONTROL flow You set it all up once. Any other HOST (aka CONTROL, Interface and many others) just streams along jobs after initial setup is done
When I write G-Code to put into the interface, what extension do I use? My milling machine uses a '.exe' extension. Thanks, Joe
See docs:interface:usage-instructions [OpenBuilds Documentation] (All the standard gcode extensions: .g, gco, .gc, .gcode, .nc, .tap, etc) EXEs are "Windows executables" - unlikely to be correct
I used the .TXT and that worked perfectly. One question- when putting the 'F' speed for a program running in mm, how fast can the NEMA 23 motor go? Thanks, Joe
Depends on what machine you have, whether you tuned your acceleration and max rates - and more importantly - what is appropriate to the job you are running.
