I don't doubt that the VFD and spindle are both very capable when they are setup correctly. I just don't have the luxury of time right now to troubleshoot the machine while the spindle is on it.

I was able to get auto-tune to run. I had to switch P3.00 to 0 so I could use the control panel instead of the signal being sent from my computer.

After auto-tune, I ran the toolpath again, and...

No sir.

I let it stop, but not much farther than that because the machine will drag the bit all over the table like a rag doll.

It does get to about 50% motor load now, but it isn't enough to...

Well, that wasn't it. I had changed the front of the machine to make it more usable and had pulled the leads from the VFD so I could change where it was mounted. I was wondering if it was spinning in...

Changing both of those settings did not help.

I am kind of at a loss right now.

I need to contact the manufacturer anyway to get a firmware update, so I am going to run it by them as well.
...

Thanks again Jim for you help.

The auto-torque boost is set to 0. From what I can tell, that is what determines how fast the VFD will give a boost while under load. Should I try it at a higher...

I changed P2.10 parameter to 2, and I changed the parameter to 1 for Auto Tune, but it says "Error" on the display instead of "MOTOR AUTO-TUNE <STOP> TO CANCEL"

There is no error, it just seems to...

It is on single phase. The GS3's will run at max 3hp on 1 phase, but that should still be within the limits of the machine.

I would almost bet that it is the P2.10 parameter. I will verify in...

I am going to quadruple check them when I get home, but yes. First thing I am going to do is check resistance on the spindle windings, and then go from there.

I have had issues in the past with this spindle on a Chinese VFD, which is the one shown in the video.

I switched out the VFD for a GS3 10hp and hadn't...

Here is a video showing of what I am talking about.

Running a new MLCS Katana .5” upcut bit at 12000 rpm, .375” depth of cut, 200ipm

The reason there is no load at the beginning of the cut is...

Below is a rant, and then I will get to the actual question. I am reposting this here to hopefully get wider exposure in order to either mitigate or confirm the issue.

I was duped with the Ebay...

The issue has been fixed. I messed up the calculation for the steps per. Once I changed that out, everything is working solid as a rock.

One of the Joe's users suggested that I unhook the motors and test them at the controller, but that would have been a lot of work.

So I let the rack and pinion drives dangle from their mounting...

Ok, so now I have another problem, and it does not seem to come up except on the Y/B motors.

If I keep to low speeds, the 203v's have no issues, but if I push up over 200 ipm or so, the 203v on...

I am glad that you can. The machine is moving under its own power.

Next step is tuning everything for the parallel port. I will order a SS eventually, but parallel port will have to do for now....

I was so flustered about it that I came home from work to reverse it and see if I blew the drives. I did not hook the motors back up yet due to Steve's recommendations to move the wiring for the...

Thanks Steve for the reply, it was a pleasure speaking with you.

The heatsink below is finned, and has 2 80mm fans attached to it with a hole cutouts in the back plate for intake air. There should...

I have hooked up my controller with my PMDX 126, 134, and 4 203v drives.

All of the status lights from the PMDX 126 and 134 are correct, but I see no status LED lights on the 203v drives in the...

None on that size spindle, I was just saying it would be cheaper to get a Hitachi X200 VFD than that HJ.

For that price, I would go with this instead, will be cheaper and better in the long run.

Most VFD's do not need 220 to pull the amps needed since most of theese spindles don't pull more than 12 amps, which is easily carried by 110.

rs485 is the connector type used to communicate with...

I figured this out once I got the volt meter out.

There was not good conductivity on #2 pole of the connector. Hard wired the spindle around that part of the connector and viola, everything runs...

Here is a video showing what my spindle is doing.

I have both a 4KW Spindle and 4KW 220V VFD.

The VFD is hooked up like this:

Machine is located in Lumberport, WV and I am asking $6500 for all of the below options.

This machine runs very solid, and is in perfect running condition.

Comes with computer, CNC Machine,...

I think a machine is easily doable for $2500 now with the R&P, it cuts a lot of the cost out in bolts and bearings, but makes up for it in other places.

Can be done, the rack and pinion is a...

I am sorry to hear you say that, but you bought the rights to use a machine plan that was made by Joe, not the forum or anything else. Joe has the right to manage the members and the forum...

Xnaron,

I know you have a hybrid now so I won't comment to your comment.

The machine is now fully Rack and Pinion, and it much closer to a production machine than ever before. Once it is in its...

The hybrid has 4 or 5 indexer users now. I will be adding mine later this year when my big machine is built.

I have posted a new break-in wizard to help test and run-in new machines and to get them running smoothly without having to hand create a bunch of G-Code.
