Well, the biggest change concerns the power supply of the external power circuit, we have replaced the DC-DC converter with a fixed voltage regulator based on 6V.Īll in all, the CNC control card is now more stable and easier to handle. This is because the Nano is the most sensitive component, the defects range from problems with the 340G chip (serial communication, bottom side Nano) to cold solder joints, problems with the internal pull-up resistors to the ripped out USB port. Unfortunately, experience has shown that when something is defective, it is 80% nano, 15% operational amplifier and 5% optocoupler, which is exactly why we will socket these components. In addition, all SMD components were replaced by push-through parts, more stable and larger screw terminals were used and all inputs and outputs provided by ESTLCAM were exhausted.Īll IC’s with the design DIL and the Nano Vers3 5V are on empty sockets, so that they can be changed without soldering if necessary. In the new REV5.1 version, the Speed and Feed over ride functions were immediately integrated into the board. Some may wonder why we are changing something ?Īt that time we already knew that the solution with the „Override Shield“ for the speed and feed function was only a temporary solution for REV3 and 4. Today I would like to introduce the official successor of the popular CNC control card for ESTLCAM.
