Re: Denford Microrouter V4
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.

Re: Denford Microrouter V4
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.

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.:thumsup:

Andy,
That all looks great, but have you considered adding a V-carve type path about 4mm deep with a V-bit cutter for the outlines?
That would give you near pin-sharp corner definition on characters and graphics where they merge and the cutter diameter cannot manage sharp corners,
Regards,
Nick
Re: Denford Microrouter V4
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

Re: Denford Microrouter V4
the machine only came with a single 6mm collet so im limited to 6mm shank tools at the moment. ive ordered some more collets from the us which im waiting to arrive, once I get them I can start using more tools.
that engraving one done with a v-bit router tool, but only 0.3mm deep. were I to have the right collet I would have done it 1mm deep with a 1mm end mill
im pretty new to wood, so still learning what gives the best results. ive since painted that engraving so its looks much better now

You have to use a CAM package that supports V-Carve paths, it's the only way to get sharp corners on deep cuts, otherwise you're limited by your tool diameter, it uses the fact that a V-bit cutters diameter varies with depth to give you corners as sharp as the tip cutting diameter of a tapered tool tip.

My Response as I knew that Triacs I supported at schools cut power to motors and often needed a reset to enable them again, I know
PC's inside out so used them as an example what e.g. means.

I answered a post and someone takes it out of context, then makes it personal with cr@p about searching for answers to qualify myself to them as if they were something special, that is trolling whether he's a mate of your's or not. He may well be knowledgeable as are you the difference being you take people out of context and afterwards apologise (As yesterday with mach3 graphics) you don't get into a personal attack trolling session.
Tell me how I was wrong (Fact: Triacs went into standby and cut power to motors not re-powering motors until reset from c: prompt), it was a regular occurence whether caused by numpty operators or machine design it happened regularly. So tell me what the male cow excrement is we are talking about. And why talking about the difference between two different machines and possible cause as to why the one without problems motors are cold after being left powered all night. If two machines are left powered one generates the heat in the motor one does not then the manner they handle the power during standby or inaction is probably the reason. I knew from experience triacs did this by totally cutting power to motors so said so, giving the example of a PC in standby or full sleep mode as an example not as a diagnosis of anything.

no word of a lie my 40 trial uses of cambam ended today and I was going to purchase it. maybe there is a better option out there I could spend my money on?

Cambam gets rave reviews and is reasonably priced, I'm not sure you'll get anything with V-Carve toolpaths for anything like the price.
Re: Denford Microrouter V4
I use Vectric VCarve which does a good job of v-carve toolpaths, and is aimed at woodworkers rather than engineers. It ain't cheap, though. Vectric offer a free trial copy, although as far as I remember it will give a good simulation onscreen of the finished work but will not actually produce gcode. You need the full paid-up version to do that. Certainly at the time I was looking, 2-3 years or so ago, I couldn't find anything else that did such a good job. For the kinds of things you seem to make, VCarve would do pretty well, but as I say, you do have to pay for it. I would be interested to hear if anyone knows of an equally good or better v-carving CAM package that doesn't cost an arm and a leg.

He's not mate but he is someone I respect and acknowledge as knowing what he's talking about. Someone who doesn't jump in with replys that are not relative to the OP's setup or about much use fart in space suit. He's valuable contributor to the forum who's probably forgot more than most on here know, you included.!

The fact that what your describing was most likely a Charge pump type setup which is very different to Current reduction.

Maybe you didn't know what you thought you knew.!! . . . . Was it really power that was cut or just Signals to the drives by the Charge pump and the Drive did the Current reduction.? Would have been easy to tell because without power the motors would lose holding torque.
But in anycase like MC said you didn't bother to enquire about the OP's setup so how could it be relavent to his machine. It's like OP saying my 10yr old Fiesta won't start and you saying well my Model T ford used to do that when Cranking handle that jumped out of socket.!! . . . Compleltly fucking pointless reply for 10yr old Fiesta.!
Re: Denford Microrouter V4
due to £££ I really need a program I can use for both my metal work and wood work. cambam can do both, although its probably not the best for both, it is good middle ground.
Re: Denford Microrouter V4
Have you had a quick look at Estlcam
Re: Denford Microrouter V4
There are Vcarve plugins available for CamBam, but it's something I've never tried. Searching for "vcarve" over on the CamBam forums will through up a few threads with various links.
I've looked at Estlcam previously, particularly it's Trochoidal feature. In general I found it a bit simplistic, which limited what you could do with/configure it, however it must be a couple years since I last tried it.
I can't remember exactly why it wouldn't work for me, but I went back to CamBam. I think it was because you had to manually compensate for the cutter width when doing Troichoidal, and Troichoidal was only available for slots, not clearing complete profile sections.
I will say though, Estlcam is good package, and is probably worth buying even if you only use it for certain jobs.
