If one or more motor is not responding, please follow the troubleshooting directions below:

For parallel Bob only! Make sure both the parallel and USB are connected.

Re-check wiring, and connections for continuity (no breaks in the wires) and check for correct wiring locations from driver to BoB.
Check dip switch settings on the driver.
Check components, by swapping the motors (ex. y-axis motor to z or x-axis driver and z or x-axis motor to y-axis driver) to check if motor functions on another driver.
Depending on software check step low active (mach 3) or invert pulse (planet-cnc) for the axis which is not responding.
Mach 3 - config/port & pins/motor outputs / Planet-CNC - file/settings/axes

I have an engine NEMA 34 from Y axis on my green bull that do not response, I already check connections and everything seems to be OK, how can I check that the motor it's working properly or not?

Is there a video link showing connections to your most recent frequency converter for the 2.2 spindle (type:YL600-2S-2K20)? Cheers.

The KL-4030 is a Keling 3.0 amp stepper motor driver. These are generally pretty robust drivers. You mentioned in the question that it worked for one hour. This sounds like it could be a contact issue with the wiring in the terminals. I would recommend that you check all of the connections. The terminals that are used in these drivers have terminals that are easily used incorrectly.

Make sure to open the terminal all the way using a small screw driver. Then insert the exposed wire into the opening and re-tighten the terminal. Make sure of a good connection by tugging on the wires.

Also, check kthe digital wires that connect from the driver to the control board.

I have a KL-4030 stepper motor driver that I only have about an hour use on it but seems to be bad already. Has anyone out there had the same problem?

Yes, absolutely. If you need two motors for a single axis, you will want to use the same terminals for pulse and direction from the breakout board.

More specifically, you will wire the step/pulse pin to both drivers, and the direction pin to both drivers. If the motors need to turn in different directions, simply swap the A and B coil connections on one of the motors.

i have checked the cnc machine for any flex and there is none but i still cannot cut circles they end up square.have checked calibration and it is correct but if i run at 4000 mm feed all comes out correct but if i change feed to say 2000 mm it makes the part small, like in tiny.

The Datasheet link for the stepper driver seems to need Microsoft Office to open. Is there another way to open that data sheet link?

That is correct. We send the fewer ribs than could be fastened within the gantry. One reduction of a rib will provide more space for the motor at the midpoint of the gantry and at the other side of the gantry (opposite the motor) can be reduced to provide more space to work with the coupling.

I'm assembling the gantry for a 5x10 greenbull and noticed that there are 9 spaces for torsion spacers but only 7 in the kit. Should I just space them out on the right side behind the motor?

You can use a compressor to unclogg the water lines of the spindle. We use this method and it works every time (so far).

WHAT ARE THE OUTPUT INVERTER (VFD) CONNECTIONS TO SPINDLE?

Since the pump will use a standard 12v power supply, you will have two wires. One of those wires will be connected from the power supply to the pump. The other wire will be connected to the power supply and the pump, but cut that wire and connect one side of it in the P terminal and the other end in the S or the O terminal depending on if you need the connection as NO (Normally Open) or NC (Normally Closed).

Step number 9 in the instruction will have the relay connection information:

I wpold like to know how to hook up my water pump (12vdc 9 amp) to turn it on and off using Mach 3. I have your Blue Brew break-out board Rev. 2.8 dated 8-12. Explain how the three relay connections work for this application? Thanks.

Yes, you can use any two of the output terminals of the breakout board to control the SuperPID closed loop router controller (a diagram is not needed with these instructions).

One output terminal will be used as an on/off (1/0 or 5v/gnd) that will be invoked with the M3/M4/M5 M-codes in your g-code instructions.

The other terminal will be connected to either another 5v/gnd signal to control speed for 5000/20000 rpm or for PWM output (recommended) for proportional speed control.

To setup this configuration in Mach3, go to your ports and pins dialog box (config menu -> ports and pins). Click on the spindle setup tab. In the Motor Control Section of the dialog, check the box for Use Spindle Motor Output and check the box for PWM control. Change the PWM Base Frequency to 50Hz.

To install the USB breakout board, there will be no driver to install nor any pop-up will be viewed in your windows task-bar, except only to notify that a USB device has been connected.

If you have planet-cnc installed it should automatically ask for a license number, which if you don't have you will continue without entering any numbers. Please read carefully since there is a pop-up that can erase the entire firmware on your board, and you will basically have a dead board.

Please email customerservice@buildyourcnc.com for further assitance.

For Windows 8.1 you need to follow special driver installation steps. Download Planet-cnc software MANUAL and scroll down to that paragraph (without it you will not be able to install and use your board).

You can increase the debouncing for the input terminals where the limit and e-stop switches are connected. Go to Mach3 and the config menu. Click on General Config... in the config menu. The General Logic Configuration dialog box will appear. On the top right of that screen, you will see Debounce Interval. Increase this number until the problem stops.

You might also want to check your wiring. You don't want the limit switch wiring close to any motor wires, including the spindle cable. The limit switch cabling should be shielded and the shielding of the cable should be grounded.
