C3DBenelux Printrbot Talk Forum • View topic - Setting Max Feed Rate in Marlin Firmware The Marlin software can use standard Atmel / Arduino EEPROM to store all the "constants" you are talking about. The working constants are loaded into RAM when the firmware boots up... either from EEPROM or from the defaults stored in the firmware. If the EEPROM "version number" matches the "version number" expected by the firmware, then it uses the EEPROM numbers. You can change the values of the constants in RAM with G-Code commands, and then you can store the modified values in EEPROM with an M500 command. I think you will find it a lot faster and easier to play with your constants this way as opposed to compiling and flashing your firmware all the time. I agree that somehow your step rate is too fast if the stepper motor just buzzes or hums and doesn't move.

(Technically, yours is more of a software question than a hardware question, but don't worry.)

browser-how-to-guide.pdf (application/pdf Object) SolarWinds Firewall Security Manager (FSM) delivers the advanced firewall management capabilities required by today’s ever-evolving security and compliance mandates and increasingly complex rulesets. Remember, security and compliance are not one-time projects, but ongoing processes that must be maintained, which is why having the right management tool is vital! With FSM, you get an all-in-one tool to simplify firewall configuration, change management, and troubleshooting—all with an intuitive, point-and-click interface. You can discover high-risk firewalls in minutes, isolate dangerous rules and security gaps, and remediate threats to ensure the safety of your network’s valuable resources. FSM Highlights:Automate security audits and compliance checksAnalyze and optimize complex firewall configurationsExpose hidden network vulnerabilitiesClean up redundant, conflicting, and unused rulesModel rule change impact without touching production Don’t take chances with your network’s security!

C syntax The syntax of the C programming language, the rules governing writing of software in the language, is designed to allow for programs that are extremely terse, have a close relationship with the resulting object code, and yet provide relatively high-level data abstraction. The development of this syntax was a major milestone in the history of computer science as it was the first widely successful high-level language for operating-system development. C syntax makes use of the maximal munch principle. Data structures[edit] Primitive data types[edit] The C language represents numbers in three forms: integral, real and complex. All C integer types have signed and unsigned variants. Integer types[edit] C's integer types come in different fixed sizes, capable of representing various ranges of numbers. The representation of some types may include unused "padding" bits, which occupy storage but are not included in the width. Integer constants may be specified in source code in several ways.

Using Unicode You can insert a number of special symbols into Mtext. In the Mtext editor select the symbol icon "@" on the formatting toolbar to get the symbols menu. But what if you want to insert a symbol not in this list? There are a number of characters in most fonts that can be inserted with some good old fashioned arcane syntax. Let's say you wanted to use the less than or equal to symbol. In Character Map select the True Type equivalent of the AutoCAD font you're using in your drawing. In the Mtext Editor type this Unicode value where you wish to insert the symbol. HOME - CadVideoTutorials Science Can Neither Explain Nor Deny the Awesomeness of This Sledding Crow - Alexis Madrigal - Technology Before we talk, you need to watch the video above. It's just one minute and 24 seconds. You'll observe a crow (probably a 'hooded crow') pick up the lid to a jar, set it down on the apex of a snow-mottled roof and slide down one side, carefully keeping its feet on the lid until it gets to the bottom. Then it picks up the lid, flies back to the apex, tests out another face of the roof, finds it lacking, returns to the original position, and slides down again. It is a remarkable demonstration of the intelligence of the crow, which sits on a smart branch in the animal tree within the family Corvidae. I wanted to know if there was a greater significance to this video and this amazing bird. Across the phone line, I heard Kamil gamely open his email and begin to watch the video. Then I started my questioning. Kamil demurred. "It is in keeping with the general reputation of corvids," Kamil told me. There are two problems with making much of the video.

C Preprocessor 6.1: How can I write a generic macro to swap two values? There is no good answer to this question. If the values are integers, a well-known trick using exclusive-OR could perhaps be used, but it will not work for floating-point values or pointers, or if the two values are the same variable (and the "obvious" supercompressed implementation for integral types a^=b^=a^=b is in fact illegal due to multiple side-effects; see questions 4.1 and 4.2). If the macro is intended to be used on values of arbitrary type (the usual goal), it cannot use a temporary, since it does not know what type of temporary it needs, and standard C does not provide a typeof operator. The best all-around solution is probably to forget about using a macro, unless you're willing to pass in the type as a third argument. 6.2: I have some old code that tries to construct identifiers with a macro like #define Paste(a, b) a/**/b but it doesn't work any more. #define Paste(a, b) a##b (See also question 5.4.) No.
