G540 4-Axis Motor Control

Soldering the 9 pin connector is the only difficult part and that will depend on your soldering skills. Gecko is well supported and works with XP. The hard part will be...

Windows 95/98 and bringing it into the 21st centrury are a litte at odds.

The simpleist option is to get a G540 and lose all the orignal electronics. I'd also recomend replacing the Steppers.

Build a big tank and fill the whole mess with a dielectric lubicant and submerge the whole mill! Radical ideas.... I got plenty;) On a more practicle note I've been pretty happy with my cool mist...

The short answer is yes you can put it all back togeather use the on board PC as it was designed to be used and keep all your electronics. The longer answer is you probably won't want to. In all...

So I've made some progress. I'm 95% done. I ended up with nema 17 's from LINengineering on the orignal drive mechanics. I get 19 IPM reliably. I'm using a keling 40V power supply and keling...

It sounds like the dir is not making it through. In mach check...

Config> ports and pins> motor outputs. For the correct pins. the default is x6,y7,z8.

On the cnc for PC board there should be...

Out grew it already!? Can't say I'm suprised. I'd like to move up to somthing like that HAAS too but at that price it'd have to be earning it's keep and I'm not so sure I wanna be that committed to...

Planning on moving up to some thing larger?

Which bearings are you after? I just did the spindle in my DM2000. The stock bearings are some spendy 6002 p5 grade by GMN. I dropped down to the abec 3 grade or an "EMQ" (electric motor quality...

I have a no name, no part # NEMA 17 Stepper that has a burnt winding. Now usually these things are so cheap I wouldn't bother. 200 step motors are common and cheap but it doubles my step count and...

What I ment by fully engaged is the super nuts come in 2 parts and they slide togeather. In my case The closer they are slid togeather puts more compression on the spring. Now I can relieve some...

Here's another difference between the 2000 and the 2400. Mine has open nuts with the spring tensioner. Oh and no Oiler either. I'm thinking of changing that. When you assembled yours did you have...

I have a dyna Myte 2000 I've rebuilding. I'll have some pics up as things progress. I'm currently rebuilding the spindle. In this peticular machine it has 3 GMN 6002 P5 bearing. 2 stacked in the...

I had an exchange with them also and got 3 part #'s

T0501-71903-DAV X2
T0501-07001-DAS X1

T0500-06002-AGM X2

They seem to think there's only 2 of these in my machine also. I measured the...

It may be that any similarity between your machine and mine is coincentadental. They are different machines. I'll have to do some Measuring but if there really was a 2mm difference for the top...

How did you come up with these?

The 6002 P5 is the industry standard part #. Not a Dyna part #.

As for a Key... Mine is driven by a plastic disk that fits the slpline.

Well I'm glad to hear you figured out you problem. I think my full sized mill does the same thing.

All my bearings are p5 grade. # 6002 P5. Too bad the othe guy didn't have the part #'s. I'd...

I just went through the spindle of my DM200 last weekend. It was fairly easy to disassemble. I'll try and post some Pics tonight. Actually I've totally disassembled my machine and I'm...

Oh yeah, an O ring can be used inside the gibbs setup to work as an anti-backlash spring that has reduced my mechanical backlash to immeasurable with a tenths indicator.

...

Because it uses it's own version of " convesational " Gcode You end up needing less lines because some of the lines are expressed as function rather than a series of steps. I read in one of these...

It's a shame you yanked off all the factory steppers and gear reduction. They actually used very nice stepper motors which will easily provide plenty of power for any cutting you can do on the...

Yeah the orignal gears were a 10:1. and probably over kill for any other setup that you might use today. And would the backlash be signifigant? That is the question. If the orignal controller...

I'm just about to tear in to a DM 2000 my self. I'm loving all the Picts! Between you and Alex I've learned a ton! Keep it up!

Now that I've read all 16 pages in this thread and Alex invited others to all to I'm ready to update my machine....

I am now the new owner of a stock functional DM2000. Or at least I'm faily...

Does any know what the supply voltage is us supposed to be going to the actual stepper driver boards on the D&M4? I get 1.8V which seems really low for a 42V supply. Voltage is good on the input...

Hi Dale,

Where was your writre up going to be published?
I like others in this thread just aquired a D&M4s. It was dead when I got my hands on it. The controller was fairly easily resurected...

I picked up a D&M4s mill. It's controller was dead. Turns out the bios has reset it's self due to a dead battery so it won't look to the floppy drive to boot. Any body knowe what those bios...
