Hey everyone, I'm running a CNC router (Pacer 4010). I have been noticing lately that my tool height has been increasing and decreasing in height as I'm running a program. I thought my waste board was uneven but when I go to tool tip my bit, I'll be getting a lower or higher measurement than when I first measured it in the start of running my sheet. I'm not sure what would cause this. I thought maybe my bit is slipping a little bit inside the collet but I checked that and it was nice and tight. Could the cone be slipping down a little bit in the spindle? Has anyone heard of this and would happen to know the possible cause? Please help. I didn't find the right solution from the Internet.

Hello, Our robot has scissor lift which is run by four tetrix motors powered by a 12V external battery pack, two on the right side, two on the left side. The way they are currently set up, the two motors on each side absolutely must run at the same speed, otherwise they will strip gears and unleash all sorts of havoc. What we would like to know is: How can we synchronize each set of motors together in such a way that they will each get full power and that they will each be running at the same, constant speed? Please help. I didn't find the right solution from the Internet. References:- http://www.robotc.net/forums/viewtopic.php?f=1&t=5401 Data Analysis Software Video Thanks

Hi, I love balsamic vinegar with olive oil for dipping. And on summer tomatoes and salads. We usually buy random stuff in the supermarket. Sometimes they are good. Sometimes they are awful like the one I just had to throw in trash on first taste. For more details Business Promotional Videos
