Also building a CRP4848

[vtx1029]

VTX1029,
Do you like your router with the Super-PID setup? Or would you go with the chinese spindle? As you can see I'm trying to decide on going with the chinese spindle or the router with the super-PID controller? Any thoughts would be helpful. I just finished a CRP4848 router and now to the point of what to put on it. Will be doing mostly wood and some plastic.

The good thing about the router is if my router fails I can easily yank it off, run to the local hardware store and buy another one and be up and running the same day.

The super PID works great! I really wish I would have purchased one sooner. With the super PID & Precise bits collets my router has done everything I have asked it to do.

But for all out use I think the spindle/vfd would be a better choice if you can swing the extra $$$. I may get a spindle some day, If I do I will go with the Hitachi vfd.

I only have 3 wires coming in to the VFD, 2 110 hot and 1 neutral. The neutral is grounded at my mains power box.

Tool Designer, could you give me specifics on how your VFD is wired? I'm looking at the manual for the Hitachi X200. It shows wiring for single and triple phase power. The X200-022NFU can handle either. I see three or four terminals on the X200 that need to be wired to depending on single or triple phase input. I can only assume the single phase is for 220VAC 2-wire (hot/neutral) and ground, not 110VAC. Assuming the pin names are standard (L1, L2, L3/N, ground), how did you wire your two hots and the neutral into the VFD? [It looks like the 3-phase model uses the same pins and are labeled R/L1, S/L2, T/L3, ground]

Since I'm working on my shop and I have capacity in my main panel, I ran a 100A sub-panel to the shop. I used 3 wire (2 hots and a neutral) and a ground to run them. From the X200 docs, I sized for 30A 220 VAC circuit for the VFD.

How do I run this into the X200? I initially bought three-prong 220V@30A turnlock outlets and plugs - Now I'm second guessing myself. Do I need four-prong?

From this thread on another board, New VFD wiring & setup [Archive] - The Home Shop Machinist & Machinist's Workshop Magazine's BBS. It looks like I connect the hots (black and red) to L1 & L2, and run the neutral or ground to the L3/N tab or the ground tab on the X200.

Does this look right? If yes, should I run the ground tab/L3 to the equipment ground in the sub-panel and let the neutral float? The ground and neutral are separated in the sub-panel and the neutral is _NOT_ bonded to the equipment ground (but they are bonded together back at the main panel).

If the above looks good, can I use the three-prong 30A outlet/plug that I purchased and run the ground (there is a green screw marked ground), or should I use a four-prong?

I hate replying to my own posts, but rereading the other thread it looks like I need four-wire: L1/L2 (black/red), L3/N (neutral), and Ground to the ground tab. Wired up just like a four-wire range. So I need a four-prong outlet/plug.

If I'm wrong, please catch me before I do something stupid

Hello Tool Designer...
First.. great job on maching and video posts...

I seen Longs Motor stuff on Ebay...
After some time on your machine...
Do you feel that these motors they sell are really as good as they claim?

Has everything been working well for you..
CNCRP seems to thing the 960oz-in motors they offer are great...
I am looking to cut cabinet parts from plywood and melamine.
THe Long's Motor stuff can be bought direct, at a savings.. I just wanted to know if you feel that the seem to perform to the specs they claim.

Do you remember what kit you got?
THanks

First off I do not want to discourage anyone from considering the motors or electronics that CNC Router Parts sell. They have spent a lot of time combining a very excellent system for their machine kits and have made them Plug & Play. There is a difference between the motors they sell and Longsmotors. The inductance of Longs motors is much higher and the power supply's provided are lower then what the motors should probably run at voltage wise. They are now offering kits with more power supply's and with 60 volts. To get the most out of the 1600 size you would need to run close to 100/110 volts, however the drivers can only handle 80 volts max. I myself am looking to buy an unregulated power supply of 72 volts to get more high end speed. However, they currently run very well with the 48 volt supply, I just have to limit the top speed to about 800 IPM rapids. Other then that I have not had any issues as of this date with the kit I purchased. With that being said here is a link to the latest offering that I would recommend.

Here is a video on calibrating the machine.

I am interested in running this test for myself. Do you have any recommendations on where to get precision ground rods like you were using?

Also what purpose does the square channel that you milled serve?
