To be honest there isnt much to convert. Just start from fresh, easy enough. See https://docs.openbuilds.com
So, I have a piece of plywood that I want to cut a circle out of. I saw a video from CNCnutz saying to avoid cutting into your spoilboard bring your bit to the spoilboard (like your zeroing) and then set the negative thickness of your material in Z. This way when you run your cut you wont cut past this value and avoid cutting into your spoilboard. I tried this in the control but when I click outside the box it reverts back to what ever was set previously. Is there a way to over ride this and manually set Z to a value I want? If the video isn't allowed I will remove.
Use the Serial console for custom commands (G10 L2 G Codes to set offset) Typing in our DRO and pressing enter Jogs to where you type
So if my material was .7in thick I could bring my bit to the spoilboard and set G10 L2 P1 Z-.7 for this example? Then I could change the Z value for other material thicknesses when necessary?
Correct! Just note whether you are in Inch mode as well (the tabs above the DRO just changes the display and jog buttons, doesnt neccesarilly put Grbl into Inch mode) , so maybe put a G20\n in there before it, to be 100% sure
I'm a bit confused on how to start the project though. I'm thinking I would zero my material like normal, then jog the machine to the spoilboard and note the negative Z value, enter G20\n G10 L2 P1 Z-.7, jog Z back above zero a little bit, and go?
Personally, I'd do the spoilboard setting first. Easier while bed is clear - Then click gotozero Z (quick mental check, looks good), then jog up Z a little more - place down stock and clamp/screw down - zero XY using whatever method you prefer - Click gotozero xyz, last check that it is where it should be - run job More personally, I just spoil my spoilboard (; good excuse to resurface very now and then also taking care of humidity induced warpage hehe
Awesome! Thanks Peter! I have been spoiling my spoilboard but I thought that accomplishing this would help me to better understand gcode a little and help to preserve my spoilboard for while longer.
Hi Peter, first, thanks for this great piece of software! I just updated Control to version .204, and now the no-longer-secret debugger always starts with Control and has to be closed manually, v202 works like a charm. Am I doing something wrong, or is this an intended behaviour? Thanks and kind regards Dieter
Yes, but why does it looks small on yours, show me the issue Its full width, and quite tall, not sure why you say its too small
Not quite, 1.0.205 fixed the default-open devtools, upgraded the avrgirl backend used for firmware flashing, and fixed some issues with our continuous integration development environment (appveyor) Hard to say what it was, without a screenshot, remember next time, grab one! Without it we don't know what to fix. Probably just the restart that did it, but good, you are back in action
Hey there - I was wondering if it was possible to configure my stepper motors individually, instead of just the "Y Axis". In my case, I have two stepper motors moving my Y axis, but they are very slightly different. Over the course of 30 inches, one of them travels an additional almost .125 inches. Is there any way I can compensate for that? I previously used a TinyG, and I could configure the travel by motor, instead of by axis. Is there a similar option? If not...does anyone know how I can get them moving the same?
1.0.204 had too small text box, about 1/3 of full width. I updated to 1.0.205 and the textbox is now full width. I forgot to take screenshot before updating from 1.0.204 to 1.0.205 because I was asked to update the software.
No, GRBL has no way of doing this, the two Y motion systems must be mechanically identical. You need to buy 2 new Y motors that are the same.
They should be mechanically identical, they have the same model number and in fact they're OpenBuilds branded. That variation is very slight over the entire course of my machine. But at the end of the day, the "Steps per millimeter" is probably 198 for one motor and 200 for the other. Is it possible that increasing the voltage to one would make a difference?
Hi Can I use the control software with a Novusun Nvum v2 controller running TB6600 4A Stepper Drivers? The Nvum is a mach 3 compatible controller.
@Peter Van Der Walt I just noticed that CONTROL is doing an update check every 15 minutes and immediately wondered if this relates to some of the random disconnects on PC's that have bad network hardware (ie they are not offloading the network processing)? It might be worth it to make a test version that only checks for updates at startup and thereafter focuses entirely on doing its job of feeding Gcode to GRBL and interfacing with the user.
Negative, already eliminated that as part of the issue. Electron's update mechanisms are well proven. If only the issue was reproducable in the lab here (; - I really need to downgrade some hardware this year lol. It seems to be mostly old PC specs, sometimes on a newer PC with some odd driver combination (thats solved after a reformat, had two of those where after a format the users never ran into the issue again) Would love to solve it forever (even if its a tick to disable something) but the affected users tend to be people who don't have the time or skill to work through many iterative tests either.
ok, so long as you are sure (-: another funny thing is that my blackbox loses connection on my Linux box (Xubuntu 18.04) after just a few commands but works perfectly on the same hardware with win10 (dual boot). I suspect the FTDI drivers built into the kernel are the problem but I must test it on my other linux box, the one that actually runs the OX and see what happens there, have to check kernel versions too.
Pretty sure, we have spent a lot of time chasing this one down Check 'dmesg' for clues, but yeah, my money is on the driver too
I understand that design decisions were made to hide machine coordinate information to reduce confusion for new users. Pardon my ignorance, but is there a way to manually query the Control software to report the current position in machine coordinates?
