Re: [Emc-users] Question on how to determine tool movement direction
Thanks Ralph, I just used DDT component on the lathe to measure axis speed and worked flawlessly. It was simpler than I thought...

Re: [Emc-users] Question on how to determine tool movement direction
This is like a drag knife control. I recall people doing that with Linuxcnc before. I think your angle would just be atan2(y velocity, x velocity). -- Ralph From: Leonardo Marsaglia [ldmarsag...@gmail.com] Sent: Friday, July 23, 2021 10:46 AM To: Enhanced Machine Controller (EMC) Subject: [Emc-users] Question on how to determine tool movement direction Hello guys, I'm thinking about using a rotary nozzle around the tool on the router to just follow the path the cutter is doing and vacuum clean all the dust and swarf it leaves on the grooves so it's easier to maint the table clean for the next job. One quick question I want to ask is: Is there an easy way to determine the direction of the movement vector of the tool to accommodate for direction changes so I can align that nozzle that turns around the tool with the direction of the cut? My idea is to make all this mechanism as simple as possible with a 3d printed structure and a little stepper to quickly rotate the nozzle to follow the path of the cut. If there's no easy or quick way of determine the direction (I thought may be there's a debugging tool or way to read this kind of data) I plan to make a custom component to constantly compare where the tool is going and at wich speed so I can triangulate the angle and that way move the nozzle in the right direction. What do you think of this?
