... Same as any other mini mill with an X axis motor stuck on the end like that. The large mounting plate and connector restricts the x axis total movement. I...
Hi Guys I'd like to ask what other HIGH VOLTAGE servo cards are some of you are using. I've just lost another Rutex which has gone noisy, grunchy motor...
This list is for the discussion of CNC and related topics including CAD, CAM, EDM, & DRO. The list focuses on the construction of home shop CNC machines along...

... Oh dear, I'm sort of glad I became rather cynical about the Rutex's and didn't buy their drives. ... Well I have been evaluating the CNC Teknix drives here...
use inductors on the output of the drives and it will work better and using a better grade of drive would also help look at servo dynamics. There pricing is...
Thanks Wayne I heard the bigger tek drives have been having problems poping fets. All claimed to be due to wrong inductance, but sort of sounds like joining ...
Try thedrives from www.cnctecknix.com They ae rock solid. Dan Mauch low cost stepper and servo motors. cases for Gecko drives kits and assembled 3-4 axis...
... Well they do take inductance seriously as it can have dramatic effect. It's very low inductance motors that seem to be the real issue. As for their Mosfet...
... Yes, indeed, this is true. And, the column setup on the minimill is pretty flimsy. It may be, in fact, that all the weight increase is in the column...
... Well, please excuse me for tooting my own horn here, but my PWM servo amplifiers can run at voltages well above what a Gecko can handle. I haven't run...
Hi Harko Which ones are more reliable? I have resistors on the outputs, but a little more inductance would give the card something to work with and slow those...
Thanks Wayne. The rating does sound a little better proportioned. Rutex use a 65Amp continuous rated FET, that rated to 40amps, and realistically only survives...
... Not yet, but they are rather honest, and easy to talk to. The designer is actually a Brit! Pete comes from Bristol, had him visit here in December, and...
This sure looks aweful similiar to a machine being marketed by SMITHY. Check it out: https://www.smithy.com/products.php?cid=11 gerald ... China of a new...
I knew you had some Jon, and Yes we have discussed this many times. I didn't know these were yours, I thought you kept them for your own use because they were...
Hi Jon, My comment was more of a general one. I thought more mass meant more rigidity and less vibration. As to Asian machines you probably need to sight them...
... 8.1mH ... What size mill do you have that you need these monster motors? Even a BP Series 2 will run just fine with 28 in-lb continuous torque motors with...
... I had a non-commercial project in 1998 or so and built a velocity servo amp with a Pulse Width modulator and FET output stage. These are in my Bridgeport...
It’s a big Avon, bigger than a BP much more rigid, much heavier and the motors are what came with it. The motors normally fetch over £1000 each second hand,...
Thanks Jon, if I get this right it means that I cannot run mach, it would have to be EMC or something like that which I think controls all the PID from the PC...
... My Series 2 BOSS BP weighs in at 5400# and has box ways. As close in design to a true milling center that you will get in a knee mill. It is easily driven...
... Shouldn't be much trouble getting it running. The install nightmares of several years ago are history, thank goodness. The only thing you will need to...
Thanks Jon I'll have to think about this EMC / Linux line, never ever got involved in it, though I think one of my friends developed some stuff with this for...
Gentlemen, I have struggled for a very long time to get Linux EMC-2 on a computer. But, having achieved this feat I cannot find how to enter a G code program...
Can you give us a little more info? What distribution, what version, what graphical user interface, what initialization file. In general, you open a file with...
Hi people, Probably a tough question, but I have just added 3 x 150oz/in steppers to my Sherline mill and now need a driver card. The motors are 2.26v and...

... The TkEMC GUI is definitely basic, but has a lot of info on one page. The Axis GUI is now the most supported GUI, and has a lot of refinements, a 3-D...
... WOW! 4A for 150oz-in motors??? Must be older motors. If they are eight wire you can run in series. You lose some lower end torque but at half the...
