Special financing available Select PayPal Credit at checkout to have the option to pay over time. Quite a few people use these alternatives successfully, including myself. Many people use a second Ethernet connection or their wireless connection on the PC so they may easily connect to the internet, which is fine. Simply connect the wires of the ribbon cable to each component in your system. What is a SmoothStepper? Sign in to check out Check out as guest.

You may choose to assign the bidirectional Pins 2 through 9 on Port 2 to be all inputs or all outputs. Back to home page Return to top. The subnet is the same if the first 3 groups of numbers in the IP addresses are the same. Learn more – opens in new window or smoothsteppet.

Warp9 Tech Design – Home of the SmoothStepper –

Please enter 5 or 9 numbers for the ZIP Code. We use this parallel port numbering format since that is etheernet this industry started.

Motor drivers often have opto-isolators in them to block current flow from the controller ESS to the high-current motor driver. If the ESS is not functioning correctly, we will need to ensure that the required voltages are provided.

The second and smoothsttepper important issue is that the motor drivers can create voltage and current spikes that can flow back into your computer and DESTROY it!


Pin 26 Pin 26 of each parallel port connector is attached to a set of header pins. The Upper Left Red LED is not used, it will never be on, unless the microprocessor can’t write to flash a critical hardware failure that we have only seen once.

This is not always any easy problem to diagnose, but it can be avoided by using a power supply with at least 1.

The cable may be shielded or unshielded. Each individual 5V jumper pin 26 is rated to carry up to 1. There are items available.

Please read this link for our complete article on Safety Information. For archival purposes we have the original manual below, but it is to be considered outdated and therefore deprecated. A very common source of these are cell phone or smart phone chargers. Be careful not to bridge the supplies! Please read the next section for more information on power supply requirements.

Mach 3 Setup Documentation: An electrical isolator blocks these currents because information is transferred from one circuit to the other without electrons light or electromagnetic fields.

What is a SmoothStepper

If you know that you will always be above the minimum current draw of the switching supply, this can be a good choice. Plus pins 2 through 9 of Port 1 These output pins are rated to deliver 0V to 5V, but may go as high as 5.


Connect this SmoothStepper to your motor controllers, and eliminate the need for parallel ports! Multiple breakout boards with their own power supplies may be connected to the ESS. It is best to ground a shielded cable at one end only. Note that you do not need to assign a static IP address to your computer if you program the ESS to use an address that is in the same subnet as your computer.

Warning messages will appear if you try to shutdown your PC before shutting down Mach. You will typically see 10 or more blinks every second from the Lower Green LED when it is communicating properly with Mach.

Delivery time is estimated using our proprietary method which is based on the buyer’s proximity to the item location, the shipping service selected, the seller’s shipping history, and other factors. This mode can only happen when the small plastic jumper shorting out both of the Smoothsteoper pins JP1.
