This a new install. I'm using grbl Ver 1.1 and UGS 2.0. Just trying to cut a simple circle. G Code from CamBam. ( Made using CamBam - CamBam CNC Software ) ( Circle 2 Test 2/17/2019 9:09:29 AM ) ( T0 : 0.25 ) G20 G90 G64 G40 G0 Z0.125 ( T0 : 0.25 ) T0 M6 ( Profile1 ) G17 M3 S1000 G0 X2.125 Y0.0 G0 Z0.0625 G1 F10.0 Z-0.5 G3 F30.0 X-1.0625 Y1.8403 I-2.125 J0.0 G3 Y-1.8403 I1.0625 J-1.8403 G3 X2.125 Y0.0 I1.0625 J1.8403 M5 M30 When I send I get this message. System starts and runs normal even without clearing above message. When I get to this point (shown below) UGS stops sending code. If I click SEND again code sending resumes. If I do a double pass the second pass goes without a problem. Below is text from Console window. Lock up point is indicated.

GRBL does not support tool change codes, so just remove the T0 M6 line. It also does not support the G64 command, so remove that too. all those 'skipping command' lines are worrying. the only things in that program that needs to be skipped is the Tx M6 toolchange command and the G64. like this Code: (Block-name: block) (Block-expand: 1) (Block-enable: 1) ( Made using CamBam - CamBam CNC Software ) ( Circle 2 Test 2/17/2019 9:09:29 AM ) G20 G90 G40 G0 Z0.125 ( Profile1 ) G17 M3 S1000 G0 X2.125 Y0.0 G0 Z0.0625 G1 F10.0 Z-0.5 G3 F30.0 X-1.0625 Y1.8403 I-2.125 J0.0 G3 Y-1.8403 I1.0625 J-1.8403 G3 X2.125 Y0.0 I1.0625 J1.8403 M5 M30
Thanks for the help. I corrected the code as you said and it ran flawlessly. It still returned some Skipping command # as shown below. What does the #xxx indicate?

Have you tried OpenBuild CAM: OpenBuilds CAM Gcode Creator - Public Beta (; GRBL compatible and free... Instead of UGS try OpenBuilds CONTROL OpenBuilds Software too
UGS will have popped up a prompt saying something like "this code is not supported do you want to skip it?" and you answered YES. What UGS did not make clear is that it will filter that code forever! So, in UGS, select 'settings' select 'Gcode processor configuration' there you will see some things in the list. untick 'decimal truncator' and remove any entries in the 'regular expression pattern remover' area.
Got it. Thanks. I'm switching over from Mach 3 so having to learn all over. Your help from these forums make it easier.
Hi all, I seem to have the same issue, sort of. I got my machine (C-beam XL) working with my new BlackBox, limit switches homing works great, thanks for the help, when I try to run a job (my gcode is generally from Makercam so the files are .nc) gives me this error. (error:20) Unsupported or invalid g-code command found in block. I tried the file(s) (which worked fine before the BB upgrade) in both UGS and Open Builds Control with the same error code. Interesting the file works fine in Easel. I was using Arduino Uno/ Cshield before and the files all worked good. Any insight would be really appreciated! Thanks!

Thanks Shawn
Its the Tool change line. Remove T0 M6. That was mentioned above as a solution to the OP problem too. G Code Errors LOL. Also, I edited your gcode post. I asked that you attach a text file so you wouldnt post the gcode in the thread. Sorry I wasnt clear about that. Ooops. LOL.
Thanks Shawn, That is what I thought needed to be done. I suspect every one of my .nc files will need to be changed! OB Cam is a little quirky, not as intuitive as UGS moving vectors around and zooming so I prefer UGS.
You mean MakerCAM? I havent used it but maybe there is a way to tell it to not output tool commands. Or maybe they have another post processor that handles grbl correctly.
I was referring to Open Builds Cam. I just ran the mouse file and it was fine! I can open the file in Universal Gcode Sender and there is an option to edit the gcode, simple fix! Thanks again!
Yes that is true! Not sure why Makercam does or why it never was an issue with the Arduino?? I went through last night and change that one line of code in UGS so I will decide which program will suit me in the future. I am an old school woodworker and I prefer inches as opposed to metric. If OB Cam could change to inches it would work best for me! Thanks again!
Note the Gcode can be inch or metric, the controller does not care so long as the correct mode code (G20 or g21) is given. Makercam may have settings that will prevent the tool code output. OBcam is still young, give it a chance (-:
Yes OBCam is young, I was referring to the view of the simulator screen, it is in metric and I like imperial. As well I can't really do anything with the view as it goes all funny and distorted! Not sure why!
1 inch = 25.4mm (; But yeah i know. We added inch mode to CONTROL will add to cam someday but lots of more important things above it on the todo. Glitchy view: export workspace from the file menu, zip and upload the .obc file to check and tell you why
Sorry Peter, glitchy (IMHO) in OB Control. The mouse is about 3" long and won't simulate properly. Zoomed way out!
Post the gcode then same rule, need the file of the thing that causes issues to see why it does, otherwise guesswork is all I can offer
I am in need of assistance. My cnc was working fine and then it said it needed version 1.0.1 at least. I updated both the arduino with the grbl and the openbuildsControl software. Now it is giving a error code and I cannot get the machine to work. The error is error: NaN - undefined [$J=G91G21X1F4979] Please help me.
Grbl 1.1 has been out since Dec 10, 2016! so excuse us for not supporting older versions, its pointless by now. $J is the Grbl 1.1 way of jogging, you need a Grbl 1.1f or newer controller to use OpenBuildsCONTROL. You still have an older version (so either you didnt upgrade to at least 1.1f, or your upgrade didnt actually succeed at all) as it rejected the $J jog command that CONTROL sends it: See gnea/grbl If your controller can't be upgraded, consider a OpenBuilds BlackBox 4X Documentation
Hi, thank you for yesterday. I do appreciate it. now I'm not sure if this is the right platform or not, but I'm trying to upload grbl to my arduino uno. I have a cnc shield, not sure which one it is. But whenever I upload grbl to the arduino it always fails and gives me a message of avrdude: stk500_recv (): programmer is not responding. Now when I remove the shield, the code uploads, but when I attach it it does not recognize the device. I have held in the reset button of the shield and uploaded the code but it did not work. Can you please help me.
If you are getting G code errors using GRBL, the post processor from your cam program is incorrect. CamBam has a post processor for GRBL.
in UGS platform,makesure you save your toolpath as grbl.gcode but my cnc is calibrated in mm.you wont get that invalid gcode file error again.
