General Mach Discussion / Re: Lost steps - again?
« on: March 02, 2013, 04:05:17 PM »
Another status report seems due: I bought an ESS from a local Swiss representative. Taking it into operation was a walk in the park. Everything seemed to work at first go. During my further tests I noticed a strange behaviour when holding the feed (Space-bar) while running a G-Code:
Do you know these phenomena? Did I do something wrong e.g. in configuration? Are there any known workarounds? (Just as a reminder: I am using Mach3.043.022, because the most recent version did not want to restart after a feed hold...)
Thanks for your ideas
- When I leave the control of feed-hold to Mach3 there is more than 2 seconds delay after hitting the space-bar until the feed actually stops. The same delay applies when I resume operation (<Alt>-R). This seems awful long to me, although the operation is precise, i.e. clean ramping down and no lost steps.
- When I leave the control of feed-hold to ESS, the response is immediate with clean ramping down and no lost steps. However resuming operation behaves strangely: Motion starts immediately after <Alt>-R, but briefly pauses after about a second. If I pause and resume a second time within that 1 second time span, the feed (or rapid) motion briefly pauses twice. Again, no steps seem to get lost, but these pauses are not very confidence-inspiring to me.
