1500w 80mm water cooled spindle be installed on the MegaV

[kc]

I did not receive my MegaV yet.

I will like to install a 80mm 1500w water cooled spindle on the MegaV.

The water cooled spindle is powerful and very quiet.

Can this be done?

[btreichel]

Yes, but probably won't work with the current router bracket. Also, you would have to control the speed manually, unless you figure out how to hack it into the control system. My suggestion is that you build the machine, get use to it; then add the spindle when you want. Most people have enough to learn about with out mod'ing the machine in addition.

Thank you for the comment.

This is not my 1st CNC.

I have seen other posts from MegaV people who added the 80mm spindle bracket to the z carriage by using a 1/4" spacer to allow clearance of the motor mount.

I will be manually controlling the speed.

I am on the hunt for a spindle right now.

I do NOT want the noisy router.

My son is experienced with electronic wiring so he will hook it up for me.

I agree it is not a easy task. I have added a 240v 2.2kw water cooled spindle (HY02D223B) for my Power Route and found that getting all the details working is not trivial and that's using a linuxcnc control board that is designed to allow for DIY customization.

1) Going with 240v was fairly easy, but the higher amps required larger and stiffer power cords. I even had to replace the cable drag chain because it was too small for both the power cord and water tubing.

2) Water cooled sounds easy, but getting the right set up can be time consuming and add to the cost. A pump, reservoir, radiator, tubing of the right size, and right fittings will easily cost $100+ if everything works. I have gone thru 3 pumps already. And then you have to deal with leaks and where you're going to put the reservoir and pump. I first mounted under the table, but the pump did not have enough power. Now I have mounted it to the back of the X axis at the same level as the spindle. Other considerations are: 1) How do you connect/disconnect the water (actually antifreeze so it will not freeze) without spilling it. So far I just have a spigot to mostly  drain the system, but liquid is still left in the spindle, tubing, and radiator. and 2) How do you make sure the system is working or that you know its not working. If needed I'll add a temperature sensor for an alarm. Currently I just have a spin meter.

3) Setting up a Chinese VFD is a daunting task with lots of warnings that comes with a 70 page translated manual describing 183 settings. Setting a parameter is a pain since you can only use the control buttons to edit one parameter at a time. Note that putting in a wrong value can damage your spindle. As far as I know there is no way to back up the parameters that you set so you will have to manually record what you set. And if you want to control it using the UI then you will need to change parameters and wiring as well as adding addition electronic components such as relays.

4) It is much heaver than the DW618 and will not fit in the same mount and it is also much taller.

5) It is much quieter than the DW618, but at high speeds it still has a somewhat unpleasant wine and does not seem quite as powerful as the DW618 at the lower speeds. Overall it does not seem to offer much real advantages in cutting over the DW618.

While the spindle is quieter, the VFD has a very noisy fan that is on all the time it is powered up that makes me want to shut it down. I have mitigated this somewhat by putting it in its own enclosure with a quiet computer fan, but even so it is still audible. It will also help when I add dedicated switch and/or relay to turn it on and off so that it is only on when running a program. As it is now I have to turn it on and off manually using the circuit breaker which is inside of my enclosure. BTW: It takes 10 seconds to power up or down.

6) Speed control is nice, but if you're only going to be cutting soft materials it is also not that important. Note that if you want to control the speed from g code the spindle takes 5+ seconds to change speeds so you will need to implement spindle-at-speed feedback. This could also increase your running time if you were to make a lot of speed changes.

7) Finally you will need to pay attention to electronic noise since the VFD is a noise generator. That means that low voltage control cables (limit switches, probes) will need to be shielded. I also used a shielded power cable to go from the VFD to the spindle and added a circuit breaker and noise filter as recommended by Huanyang.

Summary: Was it worth it? I'll say yes since I learned a lot and gained a working knowledge of electronics and linuxcnc. It is nice to have a quieter automated spindle. I just wish that it could run in the 0-8000 rpm range with sufficient torque to be useful.

I will be using shielded wiring and getting a larger drag chain.

I am still a rookie at the CNC business, but I have learned a great deal these past 6 months.

The kit I purchased has everything included, even the pump and some hose.

I had a Chinese CNCEST 6090 with the same spindle and already have my pump water and nontoxic antifreeze ready, all I have to do is weight it down and insert it.

I never did get the 6090 CNCEST machine to operate correctly even with the help of experienced people.

I even had a Mach3 technician try to help.

The Mach3 settings were set exactly as in the manual they sent me.

These folks even checked my CRV and tool path files which were good to go.

We all came to the conclusion that the breakout board (BSMCEO4U-PP) was bad, and the "Z" carriage was also bad because sometimes it made a loud bang sound when it would rise.

I told the people I purchased it from about the problems, but they knew absolutely nothing about troubleshooting and kept sending me the same driver files over and over again.

I ended up returning it and getting my money back.

I should have purchased the MillRight MegaV back then.

I have assembled 2 different CNCs so far, and the MegaV looks like it should not be difficult.

I know there will be some kinks to work out.

If I get stuck, I am not afraid to ask for help.

[oldtech]

Sounds like you're ahead of where I am.

BTW: To fit the 80mm spindle on the Power Route I cut out two circular shims 9mm (89mm -> 80mm) thick from 1 inch MDF while I decide on a mount. So far I have not seen any issues with the shims other than that they will break easily if mishandled.

The spindle I purchased comes with a mounting bracket. All I have to do is drill some holes into the Z plate and mount it with a 1/4" aluminum spacer.

I have the powerroute with 3hp, 120 volt water cooled spindle. Only ground the shielded wire at the VFD, not at the motor. setting the parameters is not that bad, amps, hertz, volts are the important ones. Allot you don't even use. I did allot of research on all of this so if you need links, let me know. I drilled and tapped my Z plate, drilled thru holes in 80mm mount, but three of the holes I made oblong on my milling machine so that I could tram the mount( tilt), and used feeler gauge pieces to shim(tram) front to back.

I purchased the Mysweety 110v 1.5 kw liquid cooled spindle for my openbuilds lead1010 machine. After I got the MegaV I decided to go with the 110v 2.5 kw mysweety spindle since the MegaV is so much more robust than the lead1010. Ditch the pump/bucket idea and go with a PC water pump and radiator for the cooling.

Thanks for the tip.  But, why should I not immerse the pump into a bucket? 

This seems like a very simple method and worked pretty good keeping the last spindle cool.

I don't know anything about a PC water pump or radiator.  

Do you have a pic of your set up?

[gofer]

Unfortunately no pics right now - as soon as I finally got it all set up we decided to move cross country. Everything is now torn down and packed for the move. There's nothing wrong with the bucket and pump I just prefer a more manageable and controllable solution.

[jms]

I have my pump in a small aquarium, its submersed. I just plug it in and go, I always unplug everything anyway when I am done, been hit by lightning 3 times and I've learned my lesson.

I have been looking online for the correct Huanyang hy01d511b 110v 1.5 kw spindle settings. Most of the information is for the 2.2kw spindle. I was wondering if anyone has the 1.5kw spindle settings. I do not want to program the incorrect settings and fry my spindle.

Here is what if found for the 1.5kw spindle.

Please let me know if these are correct.

p0013 = 10
P0000 = 50
p0004 = 400
p0005 = 400
p0009 = 0.2
p0309 = 400

I bought a HY01D523B (220V input) The settings I have are PDxxx numbers.
I have a 24000 max RPM (400HZ) spindle motor at 1HP. The following note was set via email from the vender "Taishi" sold through Amazon.


"If you use this VFD for this spindle motor 0-400HZ , Please set the parameters of the VFD as our following suggestion step by step, and don't change the sequence:
Step 1: Set PD005 =400
Step 2: Set PD004 =400
Step 3: Set PD003 =400
Step 4: Set PD072 =400
PD144=3000
This link to a video: youtu.be/8mbLw3ytnFo"

I would think the vender would verify these settings for your system.

Would you mind assisting me with this upgrade? I know how to tap and die and fab. But am not sure of where to start with it. Also the spindle I have is like 238mm tall and 80mm wide. Will the stepper motor be able to handle this type of weight? I was also looking at the next wave spindle as it is (80mm x 180mm) but is double the price! Do you think the 50mm height difference is worth $800 vs the $400? Again any help would be amazing! Respectfully
