This would totally work for that application. This cable carrier is used for any object that needs to move and carries some electrical or tubing within it. This cable carrier is great for cable management where you want to make sure the wires and tubes are in a position that you set, not where the wires and tubing want to go.

[311] I am looking to use this type of thing with a pipe for theater. Where the pipe can be lowered and it would have electrical and signal cable inside. Is this good for that or should I look at something else?

The connections between the driver and the breakout board(USB/Parallel)22-24 AWG wire is preference also going from the potentiometer going to LSPS(laser power supply) , now going from the power supply to the drivers/laser power supply 16-18 AWG wire is our preference.

could you make available a larger size picture of the exploded view of the BlackTooth laser cutter? I would like to use for reference when building my laser cutter, but it is too small to be really useful.

I recommend using a an output terminal to turn on and off the laser for safety. All you need to use is the M7 (or 8) to turn the laser on and M9 to turn it off. These M codes are use in conjunction with the output terminals to control external devices. The last Pokeys57CNC tutorial part explains this concept. You can use this idea with your controller.

How do you configure usb cnc and the mk1 board to toggle the laser? I use jscut.org to create gcode files and am wondering if I create a setting to disable the laser when it goes a certain distance above 0 on Z+.

Yes, you can connect a THC, Torch Height Controller, with the Mach3 USB controller. The THC uses the inputs to determine if the z axis needs to move up or down according to the arc of the plasma torch. The THC connects its outputs to the inputs of the controller so the controller will be informed of the states of the plasma torch.

I am interested in using the Mach3 USB interface board. I was wondering if there was a way to run a torch height controller with this board for use with a plasma cutter, and if so do you know of any THCs that will work. Thank you.

How long does processing typically take before a Blacktooth laser cutter ships? I see a week on a lot of the answers, but my order is pushing two. Since bad luck tends to follow me around, I just want to make sure I'm still in the realm of normal processing time.

I was looking for a MYJG80W power supply but I see you may not have the 220 volt version. Do you have these as yet and if not what can you advise on availability or where I may find one...Thanks

The redLeaf CNC computer systems will have either Mach3 or LinuxCNC installed as per the customer's request. If the Mach3 license is purchased, the license file will also be installed on the redLeaf CNC computer system.

The Mach3 or LinuxCNC settings will be configured during the assembly of the system. We contact the customer to determine the drive (mechanics) and inertial (weight of gantry and other parts of the gantry) specifications in order to correctly configure the steps per inch, velocity and acceleration.

I have a 4' X 8' table with carriages that use nema 23 motors. I have a hypertherm 45 plasma cutter. I have 20 degree 20 pitch rack gear. Can you suggest a plug and run system that I can use for cnc plasma and cnc routing?

Does your plasma cutter have an external trigger that voltage can be applied to make the trigger engage? If I known, please provide the brand and model of your plasma cutter so we can determine this.

Additional Information:
I converted my blackToe to do plasma cutting. Used the Motor control relay on the break out board and just wired it into the plasma cutter trigger. Put a large pan (like a car oil drip pan) with about 1/4 inch of water on the table and attached fixtures. 400 15ga parts later it's still working great.

That is so cool!!

Hello I bought a full setup of parts a couple years ago to make a cnc router and now I have decided that I want to make a cnc router/plasma. I was wondering how to go about hooking up the plasma to the breakout board

Depending on the type of motors and connection type, you could adapt your motors to work with our electronic packages, but you will receive additional motors since our kit is complete.

Now you will have to take into affect the actual motors you have and compare or get accurate replacements(Ex. our 425 oz motor(1/4" input shaft) will have to be same size or similar entry holes)

Your Controller board will be the major issue, due to its wiring and processing manner, you can view the connections for our breakout boards to compare with yours!

Do you have any videos or plans for how to make a strong table for a large CNC router? I saw the torsion box videos but would like some more guidance on how to build just a good table.

Do you have an oscilloscope? You will be able to see the PWM signal and determine if the output is correct. Make sure that you are using the 10V from the VFD as the voltage reference for the 10V terminal on the Mach3 USB controller. The 10V terminal is an input, not an output on the Mach3 USB controller. The 10V is the top voltage signal level that the Mach3 USB controller uses for the PWM signals 100% duty cycle.

[575] I have the wiring and programming and parameters set the same way that you do in the spindle speed control and outputs videos, I can start and stop the spindle with mach3 but can't seem to control the speed. Can you think of solutions?

You will want to connect the homing switches (which may also serve as your near limit switches) to different input terminals. It's ok to add more limit switches with the home switches, but each home should be on independent inputs. For example, connect home X and any other limit switch to IN1, connect home Y and any other limit switch to IN2, and so on. This will allow you to properly use the "ref all home" button in Mach3.

Additional Information:


Additional Information:
In the instructions (diagram 1) you show all the home switches connected in parallel? But here you say they need to each have their own inputs. "You will want to connect the homing switches (which may also serve as your near limit switches) to different input terminals." I dont see how the second and third axis can go home if the first axis has already closed the parallel circuit unless they back off a bit until the switch opens up again before the next axis goes to home? My machine has no limit switches so I assume they are home switches.

[575] I have finally got my limit switches wired and working - thank you. Can they also used as homing switches and if so it it just a question of looping the two inputs on the board i.e. the limit and home terminals IN2 to IN3

Are you able to install a newer version of Mach3? If you are worried that your configuration will be lost, you can save the configuration by copying all of the XML files from the Mach folder. The XML files contain all of the settings that you applied in Mach3. Just in case the XML files are not compatible with the new version, make sure not to erase the current Mach3 that you have on the machine.

CamBam specifically creates the g-code (machining operations) instructions to be loaded into Mach3. Make sure in your CamBam g-code file parameters, you are using the Mach3 post processor. If you have already done this, let me know. If you are not sure how to do this, let me know.

I am having trouble connecting the cambam program with my Mach3 to my 4X8 Blackfoot CNC machine. Where can I get help on this issue. Have had my machine since 2015 and have not been able to use it. Thank you

Absolutely! You can have almost unlimited limit switches and home switches on this controller. It all comes down to the wiring scheme used. I recommend the home switches be on separate input terminals. For example, IN1 would have the X home switch, IN2 would have the Y home switch and, IN3 would have the Z home switch if you plan on using home switches for the Z axis.

Adding the limit switches, these can be located on any input you want, even on the IN1, 2 or 3. The wiring scheme I like to use is as follows:
- IN1 has the X home, X limit ++, and X Limit --
- IN1 has the Y home, Y limit ++, and Y Limit --
- IN1 has the Z home, Z limit ++, and Z Limit --

In most cases, the Limit -- is the same switch as the Home switch.

These can be wired as NC (Normally closed) as a serial scheme, or as NO (Normally open) as a parallel scheme.

To understand the limits and wiring schemes, check out this video:

[575] Hi, for the manage the limit switches, is it possible to have, for example, the same limit switch for X-- and X homing? And what is the configuration in mach3? In my CNC machine they are in the same position. Thank you
