When the machine hits the limits it stops but the switch is still tripped so clicking the Mach3 RESET button doesn't do anything. How am I supposed to get the machine to move off of the limit switch so I can continue working?

What problems are you experiencing?

Additional Information:
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.

[575] How do I get the USB Driver to work with Mach3 Version 1.84

When you plug the USB controller into the computer using a USB cable, and the planet-cnc software is running, you will be presented with a dialog box that will contain a text box for the key that you received from the planet-cnc folks.

However it how do I get the software to work? PlanetCNC sent me a key that looks like it will only work with a backup control board I purchased from them?

For the USB controller and reversing the rotation for a motor, you would need to do this in the software (planet-cnc). In the configuration, you will need to reverse the direction by inverting the direction output.

Technically, the motor changes direction when the direction signal changes from a high to a low, or vice verse. For instance, the motor turns in one direction when the direction signal is, say, low. The motor will turn in the other direction when the direction signal is high. High is 5v and low is 0v or gnd.

I have wired the step motors with the USB breakout board. When I jog the y axis it travels in the wrong direction. How do i switch the motors rotation?

Hi there, when the gantry bumps up against a limit switch and triggers it, how do you tell Mach3 to allow me to jog the motor away from the limit switch? ie: I can't press RESET because the limit is open.... how do I move it? Thx.

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?

The 2.2kW spindle will have the same amount of torque and strength using either the 110V or the 220V inverter. Nothing will significantly change in either application since the 110V inverter has a small step up transformer which will increase the voltage from 110V to 220V to run the spindle efficiently.

Additional Information:
I'd like confirmation on this -- isn't there a cost in efficiency to having the 110v step up to 220v?

Good morning, I would like to know if the strength of the 2.2kw spindle is weaker when using the 110V version of the VFD. Does it have the same power as the 220V version VFD?

There are many ways to wire an emergency stop switch. The simplest, and arguably the most certain, way is to wire the switch into the incoming power so that throwing the switch kills all power to every part of the machine. Here is a diagram showing how a customer wired such a switch on their blackTooth laser which you could adapt to your needs. http://www.buildyourtools.com/phpBB3/viewtopic.php?f=12&t=4872

Alternatively, you could use an input pin on your USB board. The wiring would depend on whether and how you might be using limit switches (single or multiple switches; normally open or normally closed). Our website datasheet for the USB board is at https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/ and shows how to configure the switches for each set up. If you use this method, you'd essentially wire the e-stop as a limit switch.

Yes, that is highly recommended for all the reasons you can imagine. Say you were doing engraving, not surfacing the spoilboard will either exhibit some areas that have no engraving at all, or areas that have engraving that is too deep. If you are cutting completely through the material, then one end may be cut all the way through but the other end will not have a complete cut, or produce onion skinning on the bottom of the workpiece.

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

The files and hardware option for our machines has been removed from the site due to the following reasons:
Difficulty for the end use of the files and the challenges (and time/money) on our side to assist in using these files.
The abuse of these files over the internet.
Ultimately may reduce the sales of machines keeping us in business.
Sadly, this is what has come out of our company attempting to be open; however, the machines sold on this site is still far lower in price than the competition for the quality that we provide as we have a great desire to engender the cottage industry to fulfill their need for low end manufacturing. My sincere apologies if this causes any inconvenience.

I was wondering if it is at possible to get a autocadd drawing of the pieces that need to be built for your cnc hardware kit

Connecting drivers from a controller to the driver does not require relays. A controller typically has pins or terminals for Step and Direction. These terminals connect to the driver's Pulse and Direction terminals. For instance for the X axis: if you are connecting from the Mach3 USB controller, you would connect the XD (X axis Direction) terminal to the Driver's DIR+ terminal, and the XP (X axis Pulse) to theDriver's PUL+ terminal, and the GND from the controller to the PUL- and DIR- terminals.

I have thorough step by step instruction for two controllers:
