This update to the EggBot driver software including the following major enhancements:.: All-new Hatch Fill extension- provides neat connections between the endpoints of the hatching, for fast, efficient filling. It is now located in the EggBot menu (rather than the EggBot Contributed) menu.
New version of Hershey Text, with many new fonts added, as well as a new option to generate a font table so that you can see them all. Removed 'Strip EggBot Data' extension to save clutter in the EggBot menu.
Added its functionality back, as 'strip plotter data' option in manual tab.This update also contains these additional fixes and enhancements:.: Unicode caused issues in layer names.: Previously using wrong pen delay value.: Spiral Wrapped Text fails under certain circumstances.: Catch certain communication failures that could cause a plot to fail.: Ignore warnings from other layers when plotting single layer. Also, improve speed of parsing documents.: Catch certain other communication failures that could cause a plot to fail.: Use pen-up speed & wrap properly when returning home after canceled plotINSTALLATION:This software is currently in pre-release and only available by manual installation.

EggBot 2.7.x updates the USB serial framework (pyserial) to version 3.0, for faster and more reliable connections.
(Following up on issues and.)EggBot 2.7.x is primarily recommended for Mac users on El Capitan (MacOS 10.11+).INSTALLATION:All users: You must have Inkscape installed on your computer, prior to installing the software.

Manual installation of this newer version is possible as well; download eggbot2.7.1win.zip.The UBW Driver Installer v 2.0 is needed for Windows prior to Windows 10 only. This installer is included with the auto-installer in v2.5.0. Windows 10 does not require a driver for the EggBot.If you would like to manually install this software, first install the UBW driver (for versions prior to Windows 10), and then download eggbot2.7.1win.zip. Extract the ZIP archive, and copy the entire contents of the extensions directory (including the 'serial' subdirectory) into your Inkscape extensions folder, replacing any identically named files and folders there.Typically, your extensions directory is located at:C:Program FilesInkscapeshareextensions orC:Program Files (x86)InkscapeshareextensionsLinux users: Manual install: Download and extract the contents of file eggbot2.7.1linux.zip.

I want to use the servo to drive a shutter for the DLP projector of my printer.It should turn around 120 deg because of limitations of my setup.Of course it is a good idea every time the shutter to go on the same position, not on a random ones.Thanks to all for the ideas. I'll wait for more opinions / modifications.Mean while I tested it. The servo moves just with the first 'M3 Sxx' command.
With 'S' value closer to the previews ones, the servo falls in a state that just buzz and do nothing visible. Exiting from this state is with 'M3 Sxx', but with 2-3 times bigger/lower 'S'.' M5' doesn't work. (Of course M4 too:) )I do not understand 'C' language and it is hard for me to find out where the preview described changes have to be made in 'spindlecontrol.c'.
OK.Everything works with the spindlecontol.c file. Sorry for all the mistakes I do.You have to enter the min and max speed you will send in gcode. This is in config.h file:#define SPINDLEMAXRPM 100.0 // Max spindle RPM. This value is equal to 100% duty cycle on the PWM.#define SPINDLEMINRPM 0.0 // Min spindle RPM. This value is equal to (1/256) duty cycle on the PWM.In my case M3SXX, XX must be between 0 and 100. You can modify this value as you want (0 to 180 if you want to work in degrees.)Then you parameter the hardware limits of your servo in the spindlecontol.c file. In my case#define RCSERVOSHORT 6 // Timer ticks for 0.6ms pulse duration (9 for 0.6ms)#define RCSERVOLONG 34 // Timer ticks for 2.5 ms pulse duration (39 for 2.5ms)In order to know the upper and lower limit, you can modify the end of the code line 109 (just to test it)#ifdef RCSERVOINVERT//currentpwm = floor( RCSERVOLONG - rpm(RCSERVORANGE/SPINDLERPMRANGE));currentpwm = floor(rpm);OCRREGISTER = currentpwm;#else//currentpwm = floor( rpm(RCSERVORANGE/SPINDLERPMRANGE) + RCSERVOSHORT);currentpwm = floor(rpm);OCRREGISTER = currentpwm;I hope it's clear.

Merry Christmas folks,So I made a serious number of tests, but the results are equal in fact.I changed:. in 'spindlecontrol.c':#define RCSERVOSHORT 15 - from 4 to 15#define RCSERVOLONG 39 - from 32 to 39#define RCSERVOINVERT 1 - with // and uncomment. in 'config.h':#define SPINDLEMAXRPM 100 - from 100 to 256The maximum that I received was to find out how to drive the servo in 90 deg. It is good that you got it working.
However I want to point out that your solution might not work in all cases. The reason is because an RC servo doesn't use the same type of PWM as is conventional. RC servos really use PPM or pulse position modulation. Many RC servos will work reasonably well on standard PWM as you have found, but there are some that won't. The reason is because RC PWM (really PPM) is supposed to have the same frame rate with only the high side pulse width varied.
For example, an 'on' signal of 1.5 msec commands a neutral servo position and 1 msec and 2 msec are the extreme positions for the servo. The 'off' time varies to make the total frame rate equal to 50 Hz or 20 msec. As stated many servos are tolerant of standard PWM, but some, particularly older servos won't work correctly.
What is the official state of servo support on grbl? I'm using grbl-servo from robotini's repo but it is based on 0.9i (we are already on 0.9j) and it seems a quick hack on spindle code. I'm thinking about porting it to the last version (maybe to trunk / master branch) and make it proper support with official configuration and own code (without touching spindle code). But i'm asking first to know if there is anything already being done right now and if you would accept the code for review (for entering the official tree) else.Maybe use pins 9 or 10 (you could free a pin by joining some endstops), therefore using timer1. What do you think? I'm still reading the code to understand if this will cause any collateral effect.
Timer1 is desireable because of the resolution to drive the servo.Also, since the servo support could eventually work in parallel with all the other functions, I don't think it's the best option to hijack the spindle code as robotini did (because M03 and M05 could potentially being used for the spindle itself at the same time). There could be a different gcode specific to the servo. I know there is also some defined in the 3d printer world (it's M280 for setting angles and M340 for setting the microsseconds). And maybe some config option to optionally disable spindle and map the M03 and M05 operations to the servo at specific positions for those who cannot alter the software generating the gcode and want to make the servo be controlled by the spindle on/off actions.
What do you think? Dear Members,please help me!I'm very newbie user, with rudimentary language skills. I would like to using the grbl servo, with usual peripherals: two stepper motor (X, Y axis), and one rc servo (Z axis = head moving).I read this posts, but not clear the setup.
My rc servo is a simple tower pro sg90 (180 degree).How can configure the spindlecontrol.c file, for goow working?What is the connection between:define RCSERVOSHORT 15 // Timer ticks for 0.6ms pulse duration (9 for 0.6ms)define RCSERVOLONG 32 // Timer ticks for 2.5 ms pulse duration (39 for 2.5ms)and the servo duty cycle?What values can giving the M03 parameters?My arduino board is uno r3.Thank you!
