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.

[/QUOTE]
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!

What faulty machine?
You were the one who mentioned an issue which involved you assuming something, but not actually mentioning enough details about when that issue would apply.

BTW, my dummy is fine, and I'm not trolling. I'm just highlighting the misguided information in a few of your posts. If I was really trolling, I wouldn't bother explaining why your posts were misguided, I'd just post ill informed responses to see how much other BS you can come up with.

No idea what the last post says, as you're not worth talking too certainly not listening too PS theres a goat crossing the bridge!

just properly ran some code on the machine, I had ot stop after 20 mins as the motors burnt my hand to touch.

all 3 seems to be getting the same temp.

how do I go about trying to resolve this?

[lucan07]

If you are still running at 36v 2.8a I would try dropping it to 1.5a to see if they still heat up if they can't handle 1.5a maybe try some different drivers. Was the machine running when you purchased it or did you never see it running?

I just googled the stepper motor model number, and it threw up a few different datasheets/catalogues.

The catalogue for MAE stepper motors is http://www.probyte.fi/pdf/HY200-3424-0170.pdf
Which confirms the 3A/75V ratings.
However another datasheet put that exact same model at only 2.1A per phase.

I can't find any definitive figures for maximum temperature, but up to 80degC seems to be a common recommendation. If you are running the motors below their ratings, I wouldn't worry too much about it.
If you're not happy with them running that hot, try what Lucan suggests, and drop the current setting further.

[andy_con]

Will drop the current one step

First bit if work completed

[dodgygeeza]

if the motor is 8 wire, then 3A is the unipolar current and 2.1 is in series and it will be 4.2 in parallel. this is typical for 8 wire motors.

Ah ah this Makes a change from me being the one clashing heads but rest assured if I hadn't been busy I'd have blasted you just the same.!! . . .Your very out of order Calling MC a Troll. He's one of the nicest and most helpful people on the forum who's replys are considered and well thought out with healthy dose of common sense applied.
He's absolutley Correct in what he was saying, Know this because I'm often the one cleaning up when people with little to no experience dish out advice with such authority that unsuspecting people often desparate to resolve problems fall hook line sinker and take it on board. Only to find out that person was full of shit.!!
Like MC this is also one of my pet hates and like him I'll always jump on people who do this because it's not helping anyone but the Ego of the tosser who's spouting bull shit.!

Have bit more respect for nice guy and don't be so quick to dishout advise if don't know what your on about.!

I haven't read all the thread so not upto speed but I recently converted a Denford router to mach using exisiting motors but with New digital drives and the motors run at worst just little more than warm while cutting. At stand still they are stone cold.
All this talk of Controller handling Current reduction is bullshit, 99.9% it's function of the drive that works regardless whether Mach or PC working or not. Drive just sense's for signals and goes into stand by if not recieved any within period of time.

I'd be checking settings and Motor phase wiring because with only 36v you shoudn't be getting hot. That said how hot is hot did you take temp reading.?

PS: Nice work on the signs.

[andy_con]

ive dropped the current to 2.4amps and things are a bit cooler, not had to chance to look into anymore of recent. but it is on my big to do list.

thanks for the tips
