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. After that, the "version number" will automatically match, and subsequent boots of the firmware will use the EEPROM values. 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.)
C3DBenelux 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? 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. AutoCAD Tips AutoCAD Tutorials for free, 2012 2013 Lessons, Videos - a Complete Course If you do not have a copy of AutoCAD, you can download a 30 day evaluation copy from Autodesk. Follow this link, or go directly to their website. You will be downloading AutoCAD 2014 and it will work fine with these tutorials. You can also try other CAD programs like ZWCAD, which are less expensive alternatives. Here are complete lessons divided into 4 levels of learning. Many lessons have videos with narration to explain in detail some of the concepts.
Tailoring AutoCAD - Lesson #12 by Ralph Grabowski When Autodesk first introduced hatch patterns to AutoCAD (more than ten years ago in v1.4), the hatch pattern was consisted of three elements: dashes, gaps, and dots. To create a repeating pattern, the pattern definition specifies an offset and angle. In this tutorial, we look at how to create our own hatch pattern and edit existing patters. Where Does A Hatch Pattern Come From? Hatch patterns are defined in a file external to AutoCAD. No hatch patterns are predefined in a new AutoCAD drawing. When AutoCAD applies a hatch pattern to an area, AutoCAD generates an infinite number of parallel patterns from the definition in the PAT file -- the infinite pattern comes to a stop when it reaches a boundary (see figure #1). The pattern consists of only lines, line segments (dashes), dots, and gaps; AutoCAD cannot create hatch patterns made of circles and other non-linear objects. The Hatch and -BHatch commands create hatch patterns at the command line. 1. 2. Command: hatch 3.
CAD-tekenen: 2D werktekeningen en 3D isometrisch, exploded views / CAD-drawing: 2D working drawings and 3D isometric, exploded views Voor het isometrisch tekenen krijg je drie nieuwe knoppen: isometric left plane, isometric right plane en isometric top plane. Je geeft daarmee aan, in welk vlak je wilt tekenen. Dat is nodig omdat een cirkel er in elk zijvlak anders uitziet. Het zijn weliswaar gelijke ellipsen, maar ze hebben verschillende standen. In de isometrische modus wordt verder het grid aangepast. Tenslotte krijg je ook een stel isometrische arceer- en vulpatronen tot je beschikking. In the isometric drawing mode, you get another three buttons: isometric left plane, isometric right plane and isometric top plane. In the isometric mode the grid is transformed, as the main axes are not under 0° and 90° as in 2D drawing, but under 30°, 90° and 150°, as can be seen from the short green lines. You also get a number of specifically isometric shading and fill patterns.
