Bouni / leaflet.draw store-reload
Last active January 3, 2016 20:58
My solution storing and reloading features on a leaflet map edited with leaflet.draw. The features are written to a hidden text-input exportGeoJson(drawnItems, $("#mapdata")); and also loaded from there importGeoJson(drawnItems, JSON.parse($("#mapdata").val()));
$(function () {
var map = L.map('map').setView([51.505, -0.09], 13);
L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
attribution: '&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
}).addTo(map);
var drawnItems = new L.FeatureGroup();
map.addLayer(drawnItems);

Smothieboard Spindle improvement

Smoothieboard Spindle improvements

Modules

  • SpindleMaker: loads the right spindle module depending on the config, deletes itself after thats done. (Like the ExtruderMaker)
  • SpindleControl: Baseclass for other spindles
  • PWMSpindleControl: For DC spindles that are directly driven by one of the MOSFET outputs (the old spindle module)
  • AnalogSpindleControl: For controlling a VFD driven spindle with an analog 0-10V signal. Some additional electronic is required to convert the 3.3V PWM signal into a 0-10V signal

Huanyang VFD RS485 commands (pseudo Modbus)

Hunayang RS485 commands

Hunayang inverters claim to be Modbus compatible - they are not :-( So here i try to create a nice list of all commands and their meaning.

I assume the use of the RTU mode.

Parameter settings

  • PD001: 2 (Source of run commands: communication port)
