Change the spindle speed by entering a different S-number: If the machine did not obviously stall, click the Run button off. Step Time – How long the step pulse is on in nano seconds. Test this axis – This will open a window to allow testing for each axis. The most common desktop CNC setup being the Stepper driver through parallel port.

Introduction to EMC2

Potentially, you could translate the extrusion and temperature command as another “virtual” axis, and hook them up with the PID loop in the EMC2, just like how you treat a normal axis. Stepper Steper Wizard Table of Contents. Set the jog rate to the maximum for each axis in turn and jog the axis. The home location must be inside the Table Travel and not equal to one of the Table Travel values.

These next options wiil be recorded in a preference file for the next run of Stepconf. Great advice from you both, thanks. A user interface is the part of the EMC2 that the machine tool operator interacts with. Views Read View source View history.

As long as external hardware does not deactivate the motor amplifiers when the limit switch is reached, one of the limit switches can be used as a home switch. This feature is usually only useful if you have presettable tools. eemc2


If you combine home and limit switches the home switch location can not be the same as the home position or you will get a joint limit error. Charge Pump – If your driver board requires a charge pump signal select Charge Pump from the drop down list for the output pin you wish to connect to your charge pump input.

This is a very common amount. For example, enter 4. It will make moves back and forth from 0.

My main worries are that the Arduino won’t be able to control three motors concurrently, although there is a new library available: In this case, only the soft limits stop the machine from reaching the hard stop. Use the PC to browse the web, play music and check email for a few minutes.

EMC2, Arduino & stepper motors – Have I got this right? – Electrical Engineering Stack Exchange

These pages should be dmc2 such that both pages do not attempt to cover the duplicate topics. Test this axis – This will open a window to allow testing for each axis. If the limit switch is encountered during normal operation, LinuxCNC shuts down the motor amplifier. I’ll take a look at that once I clear my desk If you are seeing an axis ending up in the wrong location over multiple moves, it is likely that you do not have the correct direction hold stfpper or step timing for your stepper drivers.


Refer to the documentation for your spindle controller for the appropriate value. Email Required, but never shown. Up to 9-axises of non-blocking synchronous stepper motor control. After selecting this a file picker pops up so you can select the.

Using the buttons provided, jog the axis to near the center of travel. On the Z axis of my machine the lead screw has 12 turns per inch. If the machine stalls, reduce the speed and start the test again. Stepper Moves One Step The most common reason in a new installation for a stepper motor not to move is that the step and direction signals are exchanged.

The advantages to using both A and B are direction sensing, increased noise immunity, and stepped resolution. It assumed that you have managed to get EMC2 installed and have run the latency tests with no overruns. This can be used after filling out all the information for this axis.

These steps may not match exactly your needs, but perhaps it will help as a starting point for further exploration.
