Paul welcome to the forum. The link you refired to used to be Machant Dice if you do a search on that you will see a lot of...

m_c what about a high-bred I believe they are much better at high rpm in keeping good torque? My mate has the original motor in bits he seems to...

For a lather spindle, a stepper really isn't good. The torque will drop of far too fast, and I'd think you'll struggle to get even those shallow...

I have virtually the same setup as you but just cant get the spindle to run with any consistency. The spindle starts and slowly builds up speed but...

Have a read of the manual for setting the pots. Plus I think there may be posts over on the Denford forum somewhere where the Denford guys give a few...

Does that board isolate the PWM in from the 0-10V output? I'm not sure if the 0-10V output from the DDCSV/RMHV will be compatible with that board....

I suppose what I am saying is 24V might be a bit low to do what you are thinking of but the limitation of the drives you have will dictate the max...

Not sure what you mean here, would you mind elaborating please.. I used the pwm signal from my bob and the https://www.ebay.co.uk/itm/111654184682...

welcome Stumpy32 I have gone from NC to Mach3 and now to gerbl Its a long road but full of interesting things :)

Hi Clive - I sort of guessed it as I'm no expert but I have a PSU rated at +24v @ 14.6 amp . At the moment I haven't tried just using the 3rd 178 oz...

Your right the RMHV and DDCSV are more or less the same. I'll use a pot connected to the sprint board for speed control for now. After a bit of...

I think the RMHV is essentially the same as the DDCSV, and I don't think there is an option to use step/dir for spindle control. And I don't think...

Have you taken in account of the voltage to the drives?

Thanks for the advice John I think Ill go with the 5 amp controller as you said.

If you use a TB6600 stepper driver set to 4A a stepper motor rated at 4.2 amps will run at the 4A set by the driver so there should be no problem ...

I have just converted a Novamill that seems to have had the same control board. I used one of these https://www.ebay.co.uk/itm/111654184682 and a...

Well only two years later and my mill has become my primary project and I have made some progress. I have the RMHV controller hooked up to the...

LIDL have 3M double coated tape 50mm x 15M - I don't know how much it costs (£1.99 at a guess) as I just dropped it into the shopping trolley and...

Ok Guys had a bit time to revisit this. Your help would be very much appreciated. The above options don’t work, however after a bit of fiddling,...

Hi, I use a ball screw, but if I decided to use a rack pinion system now. Two accurate reasons - Long spherical screws will easily cause...

You only need to have the spacer tubes made. Changing the bearings to AC type will be better. If you send them all back you may not get the postage...

I bought similar 0.75KW 1 HP, water sealed 3000-8000 rpm with 5 bearings Paid £153 + £18 custom DHL, coming on Fri I will use mostly for steel...

I talked with the seller and it was a heated phone call and he said i didn't know what i am talking about and went to say that it's because of my...
