Denford Microrouter V4

[lucan07]

I'm bored tonight, so here we go from this thread alone
If you had at least some clue, you'd know it's reduced current mode, not voltage mode. Getting a basic thing like that wrong could cause major issues for inexperienced people, or at the very least confuse their understanding of the settings.

Current/voltage reduced when not in use, how can this cause a problem?

PC standby should have no effect on stepper motor current, unless the PC is shutting down enough to also shutdown the motion controller and disable the stepper drivers. Also, at this point, Andy had not even mentioned what system his Triac is running.
But given we now know it's Mach, if the computer shut down enough to drop communication with the ESS, I would expect Mach to display an error, or even crash when the computer exits standby.
However, I've never ran an ESS, and all my machine computers are set to never enter standby, and to only shutdown when requested to.

I said triac probablty goes to standby like a pc and quoted pc modes as an example, no problem with this machine so whats your point.

So despite not knowing the Triac in question was running Mach/ESS, you posted up about a relatively obscure problem, that probably only affected certain controllers, despite the fact Denford fitted multiple different controllers.

I new triacs had that facility and problem so mentioned it, it was not regarding the faulty machine rather the one that was working!
Pick your dummy up and go troll somewhere else!
