I'm not concerned about bitrate. Most drivers can output max 300KHz anyway. The concern is that the cabinet is a hostile EMC environment. Check the theory on why a twisted pair is used in almost...

OK. I know how you feel as I also installed Linux and had many fights before giving up. That was also "way back". But installing BDI RC46 was so easy I could not believe it. Boot CD, click on install...
You're right. But those are easy to debug. Add to that the possibility that the step signals have jitter on them, getting worse at higher speeds. Alas not so easy to debug even with a good...
@Scud: You should check why it was damaged, or the new one might go the same way. I looked at the schematics, and you should check the diodes D1-D8. Do not use slow rectifier type diodes in these...
@Ger: Sorry I confused G100 with the "old" Geckos. Just went over and browsed through the manual for it, and from that it looks like the G100 is the hardware that can be used to implement a...
The Gecko might do this, but it does not know what the other axes are doing.
So the path will not be correct unless moving only in a direction parallel to one of the axes. A move in one axis must be...

Bump!
Please ask around if you know someone hwo might have this info.

AC Servo?
If it's a Permanent Magnet type it must be run synchronously. You could probably make it run using a VFD, but not using it's full torque. Reason is that the VFD does not know if the motor...
Your rectifier PIV rating should be AC * 2,8 + 50% safety margin.
Is it? Time constant is L/R, and you will be cutting both L and R in half, so .....
And you will have doubled the inertia, so no gain there either.
Use thin plastic wrap. The one you use to pack food in. Just wrap it 2-3 times around your keyboard.
Do not use this to wrap your PC or screen! It will stop the cooling air flow.
Correction: I...
You need to give more information! What size is it? Make, model?
The torque that will be fine for an Emco F1 will not be able to move a Bridgeport at all. When reversing you need to go through zero...
OK, so it is not controlled through the parallel port. Then it is quite possible the port does not have enough drive capability. Try to blow the dust off of an old PC and try that to make sure the...
Acceleration is important if feed speed is. For styrofoam I guess it does not matter much if the cutting speed is too low, but for some materials it may burn (wood) or work harden (stainless). If...
If using a 36V power supply and a chopper drive it will not consume 7A to supply 7A to a 1,4V motor. You'll be closer if you assume V*A will be the same on input as output. Add some for losses, but...
Mill it out of something else. Make a rubber mold over that, and cast ice sculptures in the rubber mold.
I don't think they make these things one at a time by hand:...
Hi,
Anyone have a user manual for Magnescale LH11-3R Sn: E101907.
Even a short description of the button functions by someone familiar with it will help. I don't even know what functions it have...
Yes Gar, I agree on you disagreeing. :)
In some cases ground can be a very local thing. One example is in aluminum melting works where a monkey wrench will not lie down! And standard aluminum...
@Xerxes: Of those, I would try the X32-10i. Since it is not the same brand, I don't know if it's exactly the same. But the blurb says it has a very good wetting ability. I believe that is what makes...
Yes, usually each subsystem ground should have the same ground potential.
When this is done using low impedance cabling there will be no risk of creating a ground loop because to make current flow...
@mcmmach: What I was trying to express is that microstepping does not improve your resolution much. Unless of course as you indicate if the motors are grossly oversized. You're right in that one...

Not much.
What I did was to mount the gearwheel on a well fitting axle stub. Then I turned it to a press fit on a stub on the underside of the table. Of course it was not possible to turn down...
Hi Eidos,
I did register but still cannot see any pictures.
I must admit my Italian is not much to brag about, so I may have missed an important setting.

Laufer = runner. In this case it's the complete moving assembly with magnets, coils and pole pieces.
Winkelung = angle. But in this case it is probably a misspelling for Wicklung=winding.
It is...
Hope I didn't scare you.

1.3lbs-in = 0,15Nm !!
If there are any nuts involved, they must be wedged inside! :eek:
My guess is they are 1,3Nm. That seems about right for 1A 3,2V if it's a fairly modern design. (1,3Nm =...
