Title: Erratic motion after installing ESS
Post by: Raychar on August 05, 2016, 03:57:17 AM

Hi everyone,

Recently, I installed ESS and found strange motion on my CNC machine. During running G-code, I hit the feed-hold button, when I hit it again in order  to resume the motion, erratic toolpath motion happened. The workpiece ruined and tool cutter broke. This didn't happen at all when I used parallel port before.

Also, feed-hold can stops the axis motion nearly at once when using parallel port. But, in using ESS,  it can't, a number of G-code lines will be run before it stops?

Can anybody help to give advise or solution?

Thanks in advance.

If it's any help this section on the ESS and Feed-Hold may be of interest http://warp9td.com/index.php/faq/faq-mach3#FeedHold

Thanks, I made the feedhold to be controlled by ESS instead of by Mach3 as it advises and now it is better...
