    Re: KX3(Novakon 135)

    Thank you! Mine is indeed a R8 version but ideally I'd prefer BT30. I had no idea there was a Smithy version as well. I have seen a early machine by Syil that looked similar, Bolton looks to have had...

    KX3(Novakon 135)

    Getting over being ill and coming off a long break working on my NM135. It's essentially a KX3/X3 with minor changes here and there. Picked it up on ebay missing all the electronics so I have a 1.5kw...
  4. Re: Acorn analog 10v & AC Servo drive RPM questions

    Managed to find a happy medium. Set zero offset to 90, minimum analog RPM to 75 and analog to RPM gain @ 320. This results in the speed being off by about 15 RPM starting at 75 and climbs in a mostly...
  5. Re: Acorn analog 10v & AC Servo drive RPM questions

    Disabled the zero RPM offset and then raised "minimum speed limit for analog" until the motor quit turning and 240RPM is low as I can go at 0v and not see any rotation or feel "jittering". Problem is...
  6. Re: Acorn analog 10v & AC Servo drive RPM questions

    Did a little more adjusting and with the analog "voltage to RPM" gain @ 326 my RPM is off by 50 at 100 RPM, 40 AT 500 RPM, 20 at 2,000 RPM and so on.
  7. Acorn analog 10v & AC Servo drive RPM questions

    I have an Acorn with H3N-TD servo drive I'm setting up to drive a spindle on my mill. I am currently running a 110ST 05030 and I also have a 130ST 05020 but I'm leaning towards the servo rated for...

    Re: Stepper voltage

    Forgot to ask, what machine are you running the servos on? That is my dream setup but seems like a waste to throw at a 400-450lb mill with dovetails. Would like to see a Syil X7 with rails, Tormach...

    Re: Stepper voltage

    Yeah I have been doing quite a bit of research on AC servos as of late. The BLDC spindle motor and controller this mill came with doesn't seem to run quite right so I have ordered a 1.5kw 3K RPM...

    Re: Stepper voltage

    Thanks for the reply. Yeah, I went ahead with the 80VDC PS-8N80. I am upgrading my X and Y axis steppers to 12nm closed loop nema 34s that appear to have drivers limited to 100VDC and the next step...

    Stepper voltage

    I have a Novakon NM-135 that I purchased as "not functional". What I received had stepper motors but no power supply or drivers. I believe the original power supply was likely 36 or 48v DC. I have...

    Re: New to me NM135

    Forgot to mention I'm planning to FDM print the motor mount and turn the stock 14mm ID 38t HTD 5M motor pulley on my lathe to fit the 19mm shaft and broach the keyway on lathe as well. I'll print a...

    Thanks, I have been checking into some 24 gauge Cat 8 wire that looks decent. I can get 10ft for about $10.

    I have also ordered a new 6nm 1.8kw 3000 rpm ac servo and 30 amp controller(sold as...

    Re: Tormach pcnc 1100 mill

    When you purchase one new it is not on the stand. If you are buying used I would simply remove it from the stand since it's not difficult at all to do and requires no recalibration after remount. Off...

    Re: Tormach pcnc 1100 mill

    I'm sure you could with the right setup. I would say worst case just pull the column off and rebuild on the other side. Not sure if Tormach columns are pinned but it should be fairly easy to tram...

    Re: New to me NM135

    I completely disassembled the mill and it's clearly superior to a G0704 or PM25. I replaced the swollen capacitor with a new 470uf 50v and wired it to a mach3 breakout and 110v. There is a jumper...

    Re: BLDC controller with PWM input

    Yeah I know they are different, I was saying PC1/2 might be 0-10v analog.

    It's my understanding that the board I purchased has both PWM support and 0-10v and there are PWM pins on the controller...

    BLDC controller with PWM input

    I have a Novakon nm135 with stock BLDC controller and spindle motor. I have no manual but found similar controllers that say:

    Re: Advice Moving From Benchtop (G0704) to VMC

    I had a Torq Cut 22 which is basically what you're getting just a slightly older model. I have also owned a G0704 CNC. There is no comparison of course.

    The Torq cut I had was a 96 and used for...
  25. Re: 1100 watt BLDC spindle controller alternative?

    I'm in the US. Found a manual for very similar controller that shows mine is likely jumpered to run 110v vs no jumper is 220. Not sure if that means the motor is still seeing 220 but it seems...

  27. Re: 1100 watt BLDC spindle controller alternative?

    Cropped it so it would be under the vip limit and still have detail where the chips at.

    The motor is fairly large but a major pain to remove. I removed the belt and 4 screws that tension...
  28. 1100 watt BLDC spindle controller alternative?

    Well it looks like XPO is now saying it's going to take 11 days to deliver from 4 states over. Seems to sit at each hub about 3 days. The shipping was $758 so it's not like it was cheap.
