I have finally fixed the problem of missing steps in my Chinese made TB6. CNC Stepper Motor Controller Keep reading for a total overview of all the associated CNC stepper motor controller problems experienced and the reasons for the problems, or jump down the page to get straight to the Step by Step guide on how I fixed the board. This stepper motor controller board fix may look complicated, but with a little explanation and with the help of pictures, the changes should be relatively quick and simple for most people. The board fix should also assist people using similar Chinese made stepper motor controllers 3 axis, 4 axis and 5 axis boards for 3. D printer, laser cutter, plasma cutter and plotter applications. I have tried to keep this guide as simple as possible so people with little electronics or CNC experience do not get discouraged. Wii Iso Just Dance. The Initial Problem. Ever since I built my DIY CNC router, I experienced noisy motors, intermittent missing steps and irregular axis travel. My machine was still generally very usable for cutting rough projects, but for finer and more defined work, there were various annoying problems. Circles were not always exactly round. Calibration checks forever seemed to wander and travel distances were slightly different in one direction of an axis travel to the other. Further, I found motors were noisy and ran hotter than I expected they should. After initially scrutinizing motor speed settings, coupling slippage, lack of torque, backlash, frame rigidity and every other component of my CNC machine, I still found no specific reason for the occurrence of the problems. I came to suspect that something must have been going on with the generation and delivery of motor step signals themselves from within the controller board. A little further investigation of various CNC discussions on the net confirmed this hunch. The problems stemmed from electronic design within the Chinese made motor controller board. The specific board uses  Toshiba TB6. After a lot of effort in working out the required modifications for the board and correcting most above CNC operation issues as a result, I wanted to help others realize the same success I had achieved from the changes. I offer the following as a how to guide. While some people may baulk at the idea of butchering their own CNC driver  board when it already mostly works, I offer some encouragement. The fix was satisfying and complete. Installation Manager 1.5 32 Bit'>Installation Manager 1.5 32 Bit. It was also relatively quick, cheap and most of all, EASY. It IS possible to end up with a reliable and fully functional motor driver board with only a small amount of time, effort and understanding invested. You do not necessarily need to know what components do, or why they do it for the solution to work. Just follow the photos and directions I have provided. I will try to keep things as simple as possible. After saying this, I accept NO RESPONSIBILITY for the accuracy of this information, or the relevance of my experiences to your situation or particular controller board. Any damage you may cause to your own board is on your own head and your own responsibility. Project Overview. The TB6. 56. 0 Stepper Motor Controller Board Basic Overview. My particular Chinese made 4 axis CNC controller board was ordered online from Ebay in early 2. The board I am talking about uses the large Toshiba TB6. The missing steps appear associated with the design of board rather than the Toshiba motor driver chips themselves. There are 3 axis, 4 axis and 5 axis variations of this particular control board, with one TB6. Bienvenidos en Espanol Welcome to the community maintained website of the LinuxCNC Project Notice the wiki password has changed See BasicSteps. I have finally fixed the problem of missing steps in my Chinese made TB6560 CNC Stepper Motor Controller Keep reading for a total overview of all the associated CNC. This fix should be applicable to all boards that are similar to the 4 axis board shown, despite the number of axis included on a board ie the required fix is just a simple repeat or reduction of the same wiring to each motor driver chip if there are more or less axis. What the Solution Fixes and Achieves Electronically. I wont go in depth with the technicals here for fear of confusing less experienced DIYers who just want their controller board fixed as a priority. However, it appears the basic problem is that the design of the board does not allow the main step driver chips to send out clean signalling to the motors. Because of the noise in signalling, intended steps may get missed occasionally and the stepper motors therefore do not always advance steps or reversed each and every time they should. This results in intermittent variations in axis travel and cutter head position. Free Drum Fills Lessons here. This is a quick guide to help with assembling the Arduino CNC Shield V3. XX.

Connecting the CNC Controller Board t. Axis Stepper Motor Driver Tb6560 Wiring' title='3 Axis Stepper Motor Driver Tb6560 Wiring' />How Much Work is Required to Fix My TB6. Board Relatively little, considering the results To fix the stepping problems, I placed a very common, cheap and easily obtained chip called a Hex Inverting Schmitt Trigger, or 7. HCL1. 4 by chip code into the circuit to turn the original dirty step signals into clean onoff steps which the motors can correctly understand and respond to. The chip is placed onto a small, separate PCB board. It then requires just 6 resistors and 1 capacitor soldered around it to make it work. This separate circuit then requires connection to the main CNC motor driver board in 1. Four copper circuit tracks on the CNC driver board then require cutting to allow the new circuit to take over operation. Then bingo, youre done  Components Required. All components listed are very common and available for only a few dollars each on Ebay or many other online sources. Introducing the 7. HCL1. 4 Chip No fear This isnt rocket science, even if you have never worked with chips beforeExplanation of the 7. HC1. 4 Chip Knowing These Basics Will  Make Things MUCH Easier. Before jumping into this project, it is good to know some of the absolute basics about the 7. HC1. 4 chip you need in the circuit. Knowing just a little will save you a huge amount of time in making and checking the required modifications. I will try to keep things simple. The 7. 4HC1. 4 Schmitt Hex Inverter Trigger ChipClick to EnlargeFig. Internal arrangement and pin pairs of the 7. HC1. 4 Schmitt Inverter Trigger chip. This 7. 4HC1. 4 chip basically takes noisy input signals and converts them to clean signals in a nutshell. The chip has 1. 4 pins in total. Pin 1. V power supply and pin 7 is a ground pin. So in essence, connecting these two pins to power alone, turns the chip on. Inside the chip circuitry itself, there are 6 SEPARATE Schmitt hex inverter triggers as shown in Fig 2. Each Schmitt hex inverter unit in the chip is serviced by two pins. An input the signal to be cleaned and the output the clean signal for use. This being the case, the pins on the chip are arranged into pairs corresponding to each of the individual inverter units within the chip. The pin pairs are pins 1 2. Each axis on the CNC Motor Controller Board requires use of one pin pair of the 7. HC1. 4 chip for this modification work. Therefore, a modification of a 3 axis CNC controller board will require use of any 3 of these pin pairs. A 4 axis motor controller board would require any 4 pin pairs and so forth. The pictures displayed later all show wiring for a 4 axis board modifications. It doesnt matter which pin pair you choose to use on the 7. HC1. 4 chip for either X, Y, Z or C axis connection, as long as the pins are a pair connected to a separate inverter inside the 7. HC1. 4. All that said.
