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!
And make sure you have the FTDI drivers installed for it to show up in the list Virtual COM Port Drivers
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
I just downloaded Open Builds Control. I have built this machine and am at the point of getting the electronics figured out. I’m using an Arduino with Cnc shield and Grbl. When I try to connect to Control I get the message “Port error: opening COM4:file not found. What do I need to do to connect? Thanks
Quit OB Control by clicking on the up arrow in your system tray (near your battery icon), right click the OB logo and click quit. Open Control and try again. HOWEVER... my guess is that your usb is having issues due to you not having much battery left. Plug in your laptop, disable any power saving features for usb. OpenBuilds CONTROL Software
I did as you recommended, no go. I then went to the Arduino IFE and loaded the Grbl library. Boom, I’m connected! Must have been the basic thing I over looked. But, even though I’m connected I get no movement on the steppers when I jog.
I havent used the CNC shield, and you havent said what version you have so I cant look anything up for you. OB Control allows you to set your grbl settings but I cant advise what those would be. You'll have to consult the docs for the shield. Basically what I'm getting at is you've connected OB control, so its working in that respect and this discussion is going to turn into a troubleshooting your build talk which doesnt really fit in this thread. Are you sure you have power to the drivers? Are they wired correctly? Is the Step Enable Invert setting correct (go into Settings and if $4 is disabled, try enabling it and vice versa.... make sure you save firmware and restart). If none of that works, open a new thread please. I know others here have used it so if I cant get you sorted, someone will.
@Woodtick found some info in this very thread. Its spindle related, but give some info on the shield OpenBuilds CONTROL Software
