Hi guys, Black box arrived the other day and hooked it up today. I have a homemade machine using cncrouterparts.com Acme lead screws. they are a 1/2-10 5 start screw. Trying to figure out how to set up the mm/steps for the machine. The default settings in the black box is 200mm which has the machine traveling approximately 6 inches or so. When I lower the number closer to traveling an inch, it crawls. Just needing to get this thing up and running. Any help would be greatly appreciated. Thanks, Shane
Newest thing is the blackbox will randomly show "undefined" in all the parameters under the GRBL settings and then the machine will do nothing. I have to shut down the software and reboot the computer to get the old settings back. Shane
No need to reboot: system tray, right click icon, quit. Start again More importantly, if it comes up like that, just hit the Refresh Settings button on the top toolbar Also, make sure you have the proper ftdi drivers, good USB cable etc as it shouldnt show that unless you have communications issues
Find the 'pitch' of your leadscrew (one rotation =??mm) Lets say its 10mm for example Math is: 200 steps per rotation, at 1/8 microstep = 1600 step per rotation One rotation = 1600 steps per 10mm (pitch) but we need steps per mm. So 1600 / 10 = 160 steps per mm. Substitute your own pitch
Running a surfacing operation now. I noticed it offsets the start and ends of the rows by the diameter of the bit used from the edges of the perimeter. Can it be set so it starts at 0 and ends at the declared end limits? Or possibly do a perimeter cut around the edge before or after the rows start? My VCarve file I use covers the extent of my travel. This widget is leaving roughly 10mm on all edges (I have a 3/4 bottom clearing bit).
Thank you, I appreciate it! Something else I wonder, is if we had an option to do the operation by rows like it does now, or if we could pick spiralish squares, if that makes sense. It helps show if tramming is off in either direction. Maybe it's only helpful to me, I don't know.
After tightening everything, I seem to have my shingling under control. I believe it was my aggressive plunge doing it. When I now go down in .1 mm (.0039 in) it is hardly noticeable. Even at .15 mm increments its ok. I think my 1 inch flat mortis just dug in. Am loving the software, starting to get some output now. Thanks for the help and suggestions.
The goal is still to keep things super simple for users too many options doesnt make thing easier sorry
v1.0.178 was released earlier today It comes with a new 3D Viewer backend thats faster, leaner and can handle massively bigger files than before. VCarve finishing passes? No problem anymore! If you find issues related to Gcode parsing/simulator/3d Viewing - please open issues on Git: OpenBuilds/OpenBuilds-CONTROL
Means your Cambam setup is not using a Grbl compatible Post Processor. Grbl only understands a subset of the Gcode, probably doesnt like G64 and G40. G21=millimeter mode G90 = absolute coordinates Check Cambam docs/forum for Grbl Post Processor info
Grbl doesn't support the G64 command so it is having a sulk! Here's the list of what it does support: gnea/grbl Cheers Adam My apologies Peter got in there first!
@Peter Van Der Walt Are the macros and keystroke mappings stored on the computer? So if I swap in a different computer I have to setup everything again?
I'll add a Backup/Restore button in a couple days. For now: 1. Press F12 to open Devtools on PC where you want to backup buttons 2. On CONSOLE tab in Devtools, run: localStorage.getItem('macroButtons') 3. Copy the JSON string outputted (and get it across to the other PCs clipboard (save to text file, copy to that pc, select content, copy on other pc or similar) On the PC where you want to import the Backup: 1. Press F12 to open Devtools 2. On the CONSOLE tab paste localStorage.setItem('macroButtons', '<Paste JSON String here between the single parenthesis>') and press enter 3. Run populateMacroButtons(); Screenshot (note backup and restore ran on same instance... follow instructions for two PCs
done! (; i am soooo deep in the CAM code (adding webworkers to speed things up) I just went to the CAM repo on autopilot! Sorry!
gyday guys have finally fitted and wired up my new BLACK BOX, plugged in the USB get green light. OK. using Openbuilds Controller , shows the COM port. now connect???? OK. it now runs the log, when finished says ,"no supported firmware detected. closing port com1." ?? i was told that GRBL was pre flashed , before i received it. apparently not??? i plugged in the other BBox (yep 2 of them), both brand new. same answer. ?? Please explain.
And make sure you have the FTDI drivers installed for it to show up in the list Virtual COM Port Drivers
Also test with everything but USB unplugged. Just USB nothing else, as wiring mistakes can cause it not to run properly
down loaded the port drivers OK. using the jog motion i can move the Z axis no prob, now the X/Y shudders /vibrate but dosnt move. it did before the BOXs tryed the calc , it dosent explain enough, as i have a 20 to 60 cog, belt system ?? what do i use?? Lloyd.
put in an initial value of 100 steps/mm, then correct it with the wizard 3 times. doesn't move? adjust the motor current according to the instructions.
Check wiring, loose connections (1 loose wire of the three) causes similar. It's only as good as you wire it
