Denford Microrouter V4

[m_c]

I'm bored tonight, so here we go from this thread alone

Many drivers have sw4 on for half voltage I believe this is for standby mode only to solve that problem, but if they are touchable they are probably not to hot they are designed to run hot.

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.

Likely the way the standby is accomplished, e.g. a PC can be sleeping completely monitoring a 3.3v micro current or running lots uf stuff in background and just turning screen & disks off.

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 do know very little about Denford machines but I believe they use the Eurostep controller on the Triac, recovering from standby the Eurostep can sometimes need to be reset from the command prompt to enable the amplifier to start thus enabling power to drive to the motors which had been cut presumably by the standby/sleep state.

On the Denford system thats getting warm control has been replaced by mach3 a smoothstepper 5 axis bob etc, its hardly a denford controlled or tuned system now, which is why I pointed out a possible difference.

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.


Andy, sorry to do this in your thread, it's just that I hate seeing people post information that is wrong, irrelevant, and/or makes assumptions without knowing the facts or at least mentioning certain things have been assumed.
As I got drummed in to me during my apprenticeship, never assume anything, as it makes an Ass out of U and Me.
