I just made an order for Vacuum Pump Controller Pressure Sensor Switch. When can I expect the delivery?

I don't see anything in the datasheet for the relay that indicates an overheat condition. While the relay is engaged, the power consumption is 400 mW and I don't believe this is enough to raise the temperature faster than the heat dissipation from the metal on the leads through convection or radiation outside of the rated temperature working ranges providing that you maintain an ambient temperature range within -40°C to 85°C (with no icing or condensation).

IS IT OK TO LEAVE THE VACUUM PRESSURE CONTROLLER PLUGGED IN ALL TIME WHEN PUMP SWITCHED OFF?

Are you trying to maintain sea level atmospheric pressure within this chamber, or are you just wanting to sense the pressure within the chamber at that altitude to determine how your product performs?

To respond, just enter another response on this page: https://buildyourcnc.com/FAQ/4675 and click on submit additional information.

Additional Information:
I would like to vary the pressure inside the chamber by using a vacuum pump, e.g. from 100kPa to 10kPa. It is to simulate the different altitude level. Then I will put my product in the chamber and test it at different pressure level.

Additional Information:
I would like to get a solution for designing this kind of chamber.

Hi, can anyone advise on this?

Additional Information:
You can use our pressure sensor to dial-in the narrow range of vacuum that you need for your project. Build an air-tight enclosure/container that will contain the project components with some/one tube fittings at the exterior of the enclosure. The fitting(s) are needed to provide the vacuum within the container.

The pressure sensor will need to also sense the pressure within the container, so, either a fitting is needed on the container, or in-line with the vacuum hose will need to be provided. You will also need a check valve in-line with the vacuum line between the pump and the container (before the pressure sensor fitting) so there will be no air escaping through the pump when the pump is not running.

All of the components can be found here:

I bought an used machine that need work how can I find the model. The owner said, he used this site for parts and manual.

Yes, you can send your electronics to us for repair, or retrofit to work with either Mach3, Mach4 or LinuxCNC. You can send us an email at customerService@buildyourcnc.com to set up your appointment.

Some of the types of CNC electronics we will consider.

- We will work on electronics from other manufacturers as long as you are ok with the Mach3, Mach4 or LinuxCNC control software for your CNC machine or CNC router.

- We will repair or retrofit used CNC electronics.

- Some customers find that electronics are overwhelming to put together so we will finish these electronics wiring and assembly for you.

The cost for these includes labor cost for the time it takes to finish the CNC electronics repair or retrofit and for any parts that need to be replaced or added.

Here is an example of CNC electronics that we worked on for a customer:

I bought a used cnc router. Can you make the electronics work?

Are you using the control panel (front panel with the speed control knob known as he potentiometer)? Or are you attempting to use the computer to control the speed?

Additional Information:
I am using the control panel, however there is no knob on mine, just buttons.

Hello, I bought your 110v 2.2kw spindle and vfd. When I turn it on it reaches the full 24000 rpm, but will not let me decrease the speed. How Can I fix this?

Modifying the Z-axis to accommodate a larger motor will be a worth while task and is possible, however we have not calibrated the z-axis therefore using the 1600 Steps-per inch in the motor tuning on our machine in our shop. We have not noticed any significant depth increments from not calibrating the z-axis but only from zeroing the z axis too close to the material. Also in your design did you specify the actual depth and the length of tool (end mill/ bit) that you are using?

I bought a Blacktoe 2 x 8 three years ago and have always had a problem with the Zid axis. No matter how tightly I've calibrated the axis it always cuts to deep. Can I put a larger Stepper motor on Z-axis using the same motion electronics that came with the original machine.

Yes Mach3 is a great program. Our 3 axis is 6'X12'X3'using all BYCNC components (incl. redsprout)

I need a customised blackfoot without spindle but mount for vacuum pump pick and place.What software do I need and what's the quote

The first step would be to reinstall the required files. You can find detailed instructions for the software/firmware installation process here. https://www.buildyourcnc.com/whiteAnt3DPrinterandCNCMachine.aspx

If that doesn't work, you should send an email to techsupport@buildyourcnc.com giving your purchase information and the system you are running so we can provide more detailed support.

The firmware for the whiteant I bought from you is not responding. How can I reload? Which firmware should I reload?

Could you specify which breakout board you have? If you have a parallel port version, be sure that you have purchased the "legacy" parallel port version from Mach4. If this proves not to be the problem, please feel free to email us directly at techsuport@buildyourcnc.com or call 281-815-7701 for troubleshooting instructions.

I need a resource, we bought 2 redfly systems and mach 4, We put one motor on for the x axis but cannot get it move. Can you direct us to some tutorial?

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.

Additional Information:
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

BYCNC Response:
The book build was intended to be 20 inches x 40 inches. Larger machines were designed after the book build was introduced so customers would have the option to go bigger than what the book offered. Check out our larger machines on the website as the machines sizes range from 1 foot x 3 feet all the way up to 6 feet x 12+ feet.

User Response:
I'm not wanting to spend $3,000+ on a machine, I want to build one that will do a 4x8 sheet of wood. Will the plans in the book scale up?

BYCNC Response:
It is possible to scale the book build up, but the rigidity of the gantry would be questionable at that span, even if the height of the gantry structure were to be increased. The gantry design would need to be modified to become a box shape rather than a flat configuration. The kits on the site were design for those wanting a larger machine.

Click the link to add information to this solution:
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.

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).

Whereb can I find directions on how to install the Mach3 USB board with Mach 4 software? I do not have a parallell port.

Yes, you can use a laptop if you have a controller that uses a USB, like the Mach3 USB card. If you don't have that, you can purchase that part here:
https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

If you have a controller board that connects to a 25 pin connector, modern laptops will not be able to connect to that port.

How old is your CNC computer system?

Additional Information:
The CNC computer system is 2013 (5 years). The built in video card went out. I will order the Mach3 USB card. Thank you.
