You will use these when setting up linuxcnc. Open the Config - select Native Units menu, then choose the MM’s.If this is the case, in mach 3 go to the config menu, motor tuning, and copy the step, velocity and acceleration values for each axis. 2.2 Step Two: Config - select Native Units. After restarting the PC, choose the MACH 3 MILL icon on the desktop to start the Mach 3. 2.1 Setp One: Open the MACH 3 MILL. ChinaCNCzone CNC 6090 router , CNC 6040 Mach3 Settings and Setup.
Setting Up H3 Software Windows 10 64Bit OperatingIt can be run on a Windows 10 64bit operating system with specialized hardware adapters.mach3 mpg setup Mach3 Rotary Axis configurationMach3 Tutorial - Overview Part 3. It only works on 32 bit PC’s up to Windows 7 with the parallel port driver, to control the motion of the stepper motors by processing G-Code. The Mach3 software turns a Windows 32-bit computer into a CNC machine controller.Setting Up H3 Software Series And IsAfter installing the software and rebooting the computer you should have four icons on your desktop. If you dont do this the software will not work and you will have to manually remove the Mach3 driver from the system. The tutorial is based on the Mach3 v2.0 series and is meant to be used as complement to the existing Using Mach 3 Mill manual.Lets get started.When first installing the software its vital to reboot the computer as the installer prompts. We will go thru the steps of setting up the emergency stop, the charge pump circuit the main axis motors, the spindle and coolant as well as the home switches and the software based over-travel limits.It is ONLY for setup and tuning of the motors.The hardware interface and connections.Now we need to do is tell Mach3 how many parallel ports and at which addresses they are located. Since Im a metric guy I choose mm.Please note that, as the message says before you get to the windows in figure 2, this selection is not for switching the actual displayed coordinates between inches and mm nor is it meant to switch between running part programs written in inches or mm. To do this we go to the Config menu and click Select Native Units and select either inches or mm and click OK. When the software is started you may be presented with the following dialog but if not dont worry.Since we are going to use the computers printer port as the electrical interface between the computer and our machine we make sure that the Normal Printer Port Operation mode is selected and since we dont want to tell Mach3 this information each time we start the software we put a checkmark in the box next to Dont mask me this again and then click OK.Metric or imperial.The next thing we need to do is to select the native units of choice. Since this tutorial is aimed at getting a milling machine up and running well start the software with the one labelled Mach3Mill.Since we wont be using a second port here we make sure that Port#2 is disabled. 0x378 is the address most onboard parallel ports use. We tell Mach3 this information by selecting Ports and Pins under the Config Menu.Figure 3: Engine Configuration, Ports & PinsFirst check that the address of Port#1 corresponds to the actual address of your printer port and that it is enabled. But other addresses are sometimes used as well. ![]() The second column sets the pin to which the step input on our motor drive is connected. In this case its three axis, X, Y and Z so we enable those three by making sure that there is a green checkmark in the first column of those axis. This is where we tell Mach3 how many motors we want to control and to which pins in our printer port the each motor driver is connected. The drives step and direction inputs are then wired to the computers parallel port which internally switches the pin to ground making the current flow thru the LED in the drives opto isolator which in turn makes the drive move the motor one step. The most common drives uses optically isolated inputs and are usually supplied with a constant +5V DC from the PC. The setting of the forth and fifth column depends on how the drives are built and how we have them wired. If you have wired it yourself you probably know the pin out and if you bought the machine and/or driver box please consult the documentation for that particular machine or check with the hardware manufacturer. The actual pin out of your machine may be different. The third column is just like the second but for the drives direction inputs, wired to 3, 5 and 7 on this machine. Now lets se if we can get the system out of E-Stop mode. Click OK to save the settings and close the dialog. As the E-Stop is the only input well use for now we make sure that none of the other inputs are enabled. In case you dont have an EStop switch you will probably have to enable the Active Low option to be able to take the software out of E-stop mode but more on that later. In this case the hardware is wired in such way that the input is brought high when the switch is pushed so the Active Low setting should not be active. The step resolution of the motor drive, full step, half step, 5, 10, 100 micro steps etc. This depends on a few things: In case of a step motor: The amount of steps per revolution, most commonly 200. The first thing in the tuning process is to calculate how many steps per unit of travel we have. With the E-stop input out of the way and working well move on.Motor Tuning:Finally well get to actually spin some motors. If it doesnt turn green go back to the dialog in figure 5 and reverse the Active Low setting for the E-stop input as described above and try again. Hopefully the blinking frame around the button will stop blinking and turn in to a nice solid green. This motor is driven by a driver set to 5 micro steps per full step. We will do one metric and one imperial example.The metric one:Lets assume we have a standard step motor with 200 steps per rev. It should be noted that other actuating systems could be used like belts, rack & pinions etc but here we will use a lead or ball screw as the basis for our calculation. (How far the table moves with each rotation of the screw). And finally, the thread pitch of the screw. In both the above cases: The reduction ratio between the motor shaft and lead screw. Skyrim male skin modSo now we take those 1000 steps and divide by the pitch of the screw, which is 5. (200 X 5 = 1000) The drive needs 1000 pulses (or steps) to turn the screw one revolution thus making the axis move 5mm. So well take the motors 200 steps multiply that by the drives 5 micro step. That means the axis will move 5mm for each revolution of the screw. The motor is directly coupled to the lead screw which has a pitch of 5mm per revolution. We do this in the lower left corner. In the Config menu, we select Motor Tuning and the following dialog should present itself:The first thing to do is to enter the steps per unit we found in our calculation. Lets tell Mach3 what weve come up with. By dragging the sliders to the right and below well adjust the speed and the acceleration of the motor.
