Finally, the status strip has the current GRBL state, progress bars for the sending of the file, planner buffer state, receive buffer state, a cycle timer, and a clock. It looks to me like Arduino Uno is going to be my best bet for my LinuxCNC project.
G81 - drilling cycle I have also made it so that you can store tool tables for multiple jobs (10 right now). I am a big fam of the smaller platform laptops/netbooks, and some of the other GUIs are just too big to use on them. And was it a certain type of arc calculation that would cause this? G81X6Y2Z-1R0.1
I am seeing light at the end of the tunnel for the initial phase of the program. G90 means move in absolute coordinates you can see how well GrblPanel is feeding Grbl by watching the Buffer and Q bars. You just click on the text of the DRO and it brings up a box to select what you want to set it for. If you just want to type coordinates and have the machine move, then as stated before you need to read about g-code. E.g. I've got a Sienci Mill One which runs grbl on an Arduino Uno. What I found was that this was not due to my GUI, but something happened to GRBL.
I have been playing around with a remote desktop with an old android tablet and it works OK, but the small buttons on my previous version made it hard. It is also possible that the previous command was also a canned cycle in which case the Z command is the bottom of the hole, and not the ending point of the canned cycle. the code is as follows: G90G20G54 Any chance you´re going to share the VB code? I'm not sure if threads will give you what you need, I use events a lot where the gui is not blocked waiting for anything. and after input this text the x value become equal to 10 y and z will Cycle time with LinuxCNC - 5 minutes 35 seconds. However, I found that using the character counting does benefit in other areas.
I also have the idea for future implementation of G40-G42, cutter compensation, which will require even more tracking of modal values, coordinates, etc. If nothing happens, download the GitHub extension for Visual Studio and try again. It uses 3 Pololu or Stepstick drivers for XYZ steppers. Wizards for pocketing and drilling. @109JB Are you planning adding buttons for zeroing a single axis? This one is user defined in the GUI user settings, but I default it to a maximum of 4 decimal places. While I could probably justify thier inclusion, honestly? text to the variables for example

I do this by having default settings of all of the modal values, and checking the machine position and offsets right when the user hits the run button.
Sign in The problem I have right now is that it works perfectly during a program run with full implementation of G81, G82, G83, G85, G86, G88, G89, but I have to figure out how to make it work during MDI input. Perhaps @chamnit could comment on whether he thinks all of the above could make a significant difference in cycle times. My $N blocks were as follows: When it happened initially I though I may have issued a command that hosed things up, so I sent the following commands in this order: G90G20G54G17G0G94 I see. 3- use regex to remove comments To start a program mid way, you have to run it and tracks everything that has happened before this point to ensure all the modes are set correctly.
Having to track states is one of the more unfortunate things of the gcode canon. Since GRBL buffers the commands, it isn't possible to simply query GRBL for what the programmed Z height from the previous command is.
