Hi Merlin, you are right, of course. I was wrong, I wrote microsec, no ns :bang: |

(Hungarians uses decimal point this way: 33.333,333 English uses 33333.333) I looked at my TB6560 driver, the OSC capacitor a small SMD part, unfortunately I can't change it. I'll try some parameter later yet. |

I'm not happier. I tried everything. Stepper motors are very loud, they runs irregular, noisily, jarring. You can hear. https://drive.google.com/file/d/0B92KqmQ4Au7naVRnSEU0M1BQQnc/view?usp=sharing After 10 minutes motors are hot, with half current setting. When they are standby, all vacillate. What I tried: TB6560: http://www.osservatoriobassano.org/TCS2015/3%20Axis%20TB6560%203.5A%20Stepper%20Motor%20Driver%20Board%20Manual.pdf -half, 1/8, 1/16 step -decay mode slow to fast DDCSV1.1: -time between DIR and Pulse 300 to 1500 -pulse signal LOW an HI I have no more idea. Perhaps software down-grade... |

Hi, I give you my opinion, but just take it as an advise, nothing more... The controller board you are using is manifactured for a Mach3 use, as is using a parallel port, and is tuned for the latency and other problem that the parallel port connected to a PC have in real time running. Your new controller is much much faster and have nothing to do with this board :palm: You need to use separate stepper driver for each axis, and you can find them really cheap on ebay if you want to start with an entry model. I would suggest you to buy a good one once and forever, so your system is then matched as it should be, quiet and running cool. Then get rid of the parallel port once and forever, as this is the pourpouse to buy that kind of controller... I will make a short video of mine running with digital stepper driver http://www.ebay.co.uk/itm/EU-Stock-4PCS-DM556D-Digital-Stepper-Motor-Driver-50VDC-5-6A-For-CNC-Router-/142190444856 (those are mine, but you dont need that much, you can find digital ones and much much cheaper. Those one are perfect http://www.ebay.co.uk/itm/CNC-2DM542-Microstep-Stepper-Motor-Driver-4-2A-Controller-24-48V-DC-Nema17-23-34/251117211299 i am happy with that and no missing steps or heating or noise, strong holding torque and auto-tuning firmware..... just have a look if you have time. Once you have built the controller it will work even for future machines if you upgrade the chassis. Any comment is fully apreciated as usual Regards |
