The VFD that this is potentially a very dangerous device that is designed to be commissioned by a licensed electrician.This guide is designed to help those who have difficulty with the connections necessary to use the laser. Lastly, an opening in the board to access the smoothness adjust trimpot, which can largely be ignored. If your motors are running overly hot then turn this down a little, if you are suffering from lack of power turn this up a little. The desired resistance measurement between the two terminals is 2. There is also measurement point beside each trim pot marked in blue. Note that this is not smoothness tuning the trim pot mentioned in the manual. This takes place of the resistor to be soldered that is mentioned in the G manual. The GRBL Gecko controller has a trim pot for setting the current limiting of each stepper motor which are circled red in the image below. Please ensure the charge pump switch on the gecko is turned off. The cooler will be marked for either 12V or V connection.

As the spindle is slowing to a stop, check that it is spinning clockwise when looking from above, should it not be any two only of the U, V, or W outputs that the spindle cable is connected to can be swapped to change the direction.

Once the above is complete, complete steps 1 through 4 of the software setup steps, and return here to test the motor as per below. You may use the up and down arrows to skip to a new parameter and a short press of the navigate button to enter and exit a parameter. To program any parameter, press and hold the navigate button for a few seconds, at which point the keypad will display the last parameter configured, initially 1. The following diagram describes the control pad functions of an E3 inverter, as described in section 5 of the manual. The following information configures the E3 for 3DTeks standard use case and this information may not be appropriate for other uses. The invertek E3 VFD has several important and several optional parameters to be set before attempting to operate. Our implementation of this device overrides some of the information provided in the manual, for example, the motor current tuning and motor wiring. Please contact 3DTek for any assistance wiring up or configuring these devices. The next step is the worst part (imho) and that’s crimping header connectors onto 25 wires.These may or may not be useful for other Gecko use cases. No power supply required and no fan, the G540 is in a separate, cooled enclosure This combination of Arduino and cncshield will go in a small plastic box with a USB socket in one end and the DB25 cable at the other.
#Controlling gecko g540 with arduino drivers#
This shield supports 4 x 8825 stepper drivers so each Y axis motor has it’s own driver I won’t be using any of these, I’ll just be using the cncshield as a way to interface the signals via DB25 cable from the G540 to grbl. Next I need a way to get the various control signals (XYZ step/direction, limit/home switches etc) from grbl to/from the Gecko. This thread will document the process of getting grbl to drive the Gecko G540 controller.įirst step was to get a couple of Ardunio Unos (if there are two Uno, does that make it a Due? ) They arrived from China today $A16 for both,Īs I’ve never run grbl before and all I know about it is from reading posts in this forum, a bit of reading was needed to get downloading the source code,compiling and installing on the Uno, A terminal program lets me run a $$ command and get a readable (if not yet understandable) response. However, I can’t access all the goodies that Easel provides unless I run grbl. It works well and I’ve been successfully creating gcode using (mostly) CamBam. I’ve mentioned in previous posts, that I run my X-Carve under Linuxcnc with a Gecko G540 controller.
