First make sure everything jogs in the correct direction. Go into grbl and invert the Z axis direction (setting $3). Once you have the axis moving correctly, then you can work on the homing direction which is setting $23. Normally Z homing is up, not down. This will set your machine zero at the upper most point of your z travel which is normally what you want.
if you read the GRBL wiki, it explains that there are 2 settings for direction, one for main direction , and one for homing direction. github.com/gnea/grbl/wiki
And also the probe not working at all. i got XYZ touch probe plus., i double check wiring to probe BLK/V+/SIG from one end to the other end., when put the probe in place attach blue wire spindle, the green LED light comes on. if i disconnect the USB cable from the computer, the probe LED turn off
Indicates you have a ground fault in your computer (DC GND connected to AC Earth) or a short in your spindle wiring (DC GND to AC earth) Try a different computer
ok, i have serious problem that i cannot figure out., please help Stepper motor ZX are working perfect Stepper motor Y its extremely hot and sizzling...
i found the problem, bad limit switch Y limit bad solding job from openbuilds store, i order 6 limit switch, one was bad from pack.
adjust the motor current using the pot on the side of the Blackbox docs:blackbox:currentadjustment [OpenBuilds Documentation] Halfway is how it ships as that setting matches the OB motors, but your motor is obviously getting too much. I would also carefully check the wiring of that motor. you say it gets hot but does it move correctly? docs:blackbox:faq-identify-motor-coils [OpenBuilds Documentation]
Yes, the motor its moving correctly., i cross reference motor wiring with longsmotor website A+ =black wire A- =green wire B+ =red wire B- =blue wire also check it with a multimeter A+/A- reading 0002 both reading 0002 ohms. the Y pot is set to the middle. Warm, but sizzling noise. after check all wirng and DC/AC ground. The openbuilds Black box Probe port is short it., try a with probe., got same problem it keep saying probe close error check wiring/reset controller. how do i get it replace., got about 3 week ago.
Turn the current down a little: docs:blackbox:currentadjustment [OpenBuilds Documentation] though some noise is expected (Stepper drivers are chopper current inverters) Disconnect everything except the USB cable from your BlackBox Then open CONTROL > connect to the Blackbox > screenshot of the Troubleshooting tab
ok, Disconnect everything except the USB cable from your BlackBox. Still same problem. We also hive two other cnc machine with openbuilds Black box., We hive remove one controller a from other working cnc machine, to double check the bad controller. Install controller on cnc machine with problems, after the install tested limit switch’s and probe., There’re working fine No Error reporting. Install back the first controller, Error with probe and limit switch Y, We also replace the limit switch, and tested the XYZ Touch probe plus on other cnc machine. Working perfect. We also notice that when we power up the controller 24v., The 24v drop about 1.4v from the 24v.. And that’s with everything disconnect except the USB cable.
Is it possible to add incremental/continuous jog to the keyboard mappings. ATM it's hardwired to the 8key. I control the CNC with a wireless numpad. I've just swapped to a MAC which it turns out doesn't recognise NUM LOCK (go figure). So the 8 key (up arrow) swaps the jog mode to continuous.
In the time since our Post processors have been updated to support breaking up jobs into seperate tool files so you don't need to
Looks like I have some catching up to do. I'm exporting from estlcam, no worries, I'll read up and figure it out. Thanks for the rapid reply!
Yeah not sure about EstlCAM, see docs:software:fusion360 [OpenBuilds Documentation] and docs:software:vectric [OpenBuilds Documentation] Or just manually export a gcode file for each tool - in order of operation Load first tool and first file and run it to completion Change tool to 2nd, rezero Z (probe makes that a breeze) and run 2nd file to completion Change tool to 3rd, rezero Z (probe makes that a breeze) and run 3rd file to completion
Can use the Estlcam flash on BB.. works great, easy to revert back to GRBL if you want takes seconds, estlcam saves your old flash before over-writing. For tool changes it pauses and waits for you to change tool, can even setup location for tool touch off. Let's you reset the z manually if you want, that's how I do it. Gary
Can't thank you enough for OpenBuilds Control. I've got a 3018 Prover that I was about to chuck but decided to give it one more go using Control. It has made all the difference between the machine working and not working. I have a quick question and I'm not sure if its a GRBL question or OB Control question - is there anyway to jump to a line number or "restart at line number"? Occasionally (because I'm an idiot), I hit a limit switch brushing or vacuuming the dust during a project and wind up just starting the whole thing over. Any help would be greatly appreciated!
No, not at this time. If you dont understand gcode enough to edit it to start where you want, then we suggest re-cam your part from where it left off.
I was wondering if someone could help me get the openbuildsCONTROL to work on my PC running Ubuntu 20.04. I've tried everything I know and it always opens to Gitea and I can't uninstall to try again. I can run on another PC, also works on Debian, and Windows 10, but the preferred one I use is the problem and the operating system is Ubuntu. It works on my old PC running the same version of Ubuntu. I think if I uninstall and try again it might fix it but something links it to Gitea, and I don't know why.
Uninstall Gitea - its not part of CONTROL, you must've installed it prior and it will be conflicting on port 3000/3001 Or change Gitea to use another port: See Config Cheat Sheet - Docs > HTTP_PORT subsection
You're amazing. I've been frustrated by this for days and you helped me solve it in minutes. Thank You!
Hi! I am looking for a way to add height mapping/surface mapping to OpenBuilds control. One identical to Grbl Candle height mapping. I read there was an attempt made already: HERE but I am very new to this and don't know how I would add the code to my version of OpenBuilds. Is there any documentation on adding code? or is there a macro that can do this? Thanks
Hello I am using Open Build Control V1.0.309 on Ubuntu 22.04 LTS. Installed via the .deb package I can't get the Openbox to connect anymore. The controller is only recognized very briefly after plugging in the USB cable, but disappears after a few seconds. Additionally there is no tab for the serial console. Also the tab for the 3D preview is no longer present. Completely uninstalling and reinstalling did not change anything. Same behavior with the current app image. Are these problems known? I have not run the Open Build Control with my computer for a long time. Therefore I know if the errors happened during the distribution update. Translated with www.DeepL.com/Translator (free version)
For the 3d preview and serial log, check to make sure they are enabled in Troubleshooting -> Application Diagnostics. They should NOT be checked.
Thanks, you are right. Serial consol and 3d are now aviable. But no stable connection over USB. Something is killing the USB connection after some secounds. Output of the serial consol:
See docs:blackbox:faq-emi [OpenBuilds Documentation] and docs:blackbox:faq-usb-connection-failed [OpenBuilds Documentation] - also disable any other applications running USB scans at the same time - Try a different PC / OS
I've found the problem Its dependet with the braille Display. If you dont use a Braille Display then you can uninstall the driver: sudo apt remove brltty More informations here: /dev/ttyUSB0 not present in Ubuntu 22.04 Tanks for help!! Mark
