In this article I will go through the entire build process for an offline CNC controller that I have made for my 6040 CNC router. Although it is made specifically for my router, most items covered should be applicable for any CNC machine for personal use. The preparation of the enclosure is covered in detail, as well as why I used certain electrical components and I will include any errors I made along the way to hopefully prevent other people from making the same mistakes.
After some searching on Aliexpress I decided to go for the DDCSV3.1 controller. I purchased the 4-axis version since I also wanted to upgrade my router with a rotary axis. Although there are plenty alternatives, I opted for this controller since it appeared simple to use, has all of the functions I need and perhaps most importantly, there is a good manual available for it in English.
Micro stepping is set to 2000 pulses per revolution. A typical stepper motor has 200 steps per revolution. If we divide 2000 by 200, we get 10 microsteps per full step. Microstepping is used to make steppers motors run smoother.
I am connecting the fan to the small 24V power supply. Since I cut one of the adaptor cables that I would not need in half and placed some connectors onto the ends, so I could hook it up to the power supply. With this setup I can connect the fan directly for full power or insert one of the low noise adaptor cables in between, just by unplugging the connector. The fan has 3 wires coming out of it: red and black for power and the yellow wire for RPM control. I am not using this feature, so I cut off the yellow wire.
Het loopt dus niet helemaal gesmeerd helaas. Ik hoop dat je eruit komt. Gewoon doorgaan met Trouble Shooten dan moet het uiteindelijk lukken. Ik heb even naar de dip switches gekeken in mijn opstelling. Voor de open loop drivers staan de switches op: 1aan, 2uit, 3aan, (2.7A peak) 4aan, (full current) 5uit, 6aan, 7aan, 8uit. (2000 steps per revolution).Voor de blauwe HBS57 stepper driver staan ze als volgt: 1uit, 2aan, 3aan, 4uit, (2000 steps per revolution) 5uit (Counter Clockwise Direction)
Thanks for your feedback. I could sometimes actually hear that missed a step, in my case on the X axis, but could have been on another as well. Apparently this was the most critical in terms of wiring / noise. I have not used the router a lot since the conversion, but with the programs I ran I did not notice any issues anymore with the new controller. Note that my stepper cables outside the housing are unshielded, so if I do have any issues these will also be replaced, but so far so good.
Non-commercial users (aka hobbyists) are permitted to use one Mach license for as many machines as they require. For commercial users (anybody who uses the software to generate profit), we require a separate license purchase for each machine. Mach1, Mach2, and Mach3 may all be used on one computer, but only one version of each will co-exist on a single computer.
Digital twins are a type of strategic digital technology that is a digital version of the actual structure that provides data on its status. It serves as a conduit between the physical and digital realms by providing a consistent means of monitoring and reacting to changes. It assists all digital leaders in risk management, preserving manufacturing efficiency, and enhancing customer service. 2b1af7f3a8
