Sounds like the IR and/or CL trim pot needs to be adjusted. Make sure you have the correct HP resistor installed and follow the manual's instructions for calibration. Fully cranking the accel pot...

Three phase motors have much less 'slip' than a single phase or DC motor. I guess the best way to explain this is to think of a marry-go-round with one person spinning it from the side. Single...

This is how I did mine.

If you have access to a boring head clamp the pulley down on some parallels, find the center of the hole with an edge finder, and bore away. The part being perpendicular...

Yes and No.

The GS1 series only support single phase input to three phase output up to 1.0 HP. A three phase service would be required to power the GS1-22P0

The GS1s do support modbus...

No noticeable problems to speak off. Maybe if there was a 5th axis it could cause some lateral flex when not in the vertical position but I don't plan on running it that way.

No problem Tom.
I ended up with a single KL-5020 for everything. More than enough umph to drive all four axes.

A side note. My machine would resonate something god awful on rapid Z movements. ...

I have the same diver and motor with a 60 pound three phase motor on the head and getting 60 IPM @ 8 IPS^2 on the stock acme screw. At first I was stuck at 12 IPM though. Problem is all three...

If I understand that right the G540 Output 1 and 2's sink current. You'll need a relay with a coil rating the same as the power supply running your gecko. Wire one side of the relays coil to the...

I am sorry, just saw the G540 puts out a 0-10V signal. So A001 = 01 is correct
G540 pin 7 (VFD GND) goes to terminal L in the VFD
G540 pin 8 (VFD) goes to terminal O in the VFD
G540 pin 9 (VFD +V)...

If you really want to make it simple, use the modbus serial interface. A $10 RS232 to 485 adapter on ebay is all you need. One of these days I will get around to doing a tutorial.

UC100 is the...

Whizbang, I picked up a rotary table like yours except it was through ebay, but it looks very similar to yours.
Any how, I tore it down in order to drill mounting holes concentric to the bore and...

Here a cell phone clip of the machine cutting for the first time under CNC with the new motor. The feed are being babied and not quite comfortable letting it rip at the suggested rates yets. But,...

Not yet. Haven't stepped foot in the garage this week between being under the weather and on the road. Can't promise anything but will do my best to make a video of it cutting and how to set up the...

So I haven't made a single chip with this thing and could not go to bed with out running some material through it. 7075 aluminum, 3/8" double flute end mill, 500 thou DOC, 6100 RPM, 117 Ipm and just...

Alrighty. Been tweaking some things in SW and converting to 2D drawings. Bear with me since it isn't something I do very often. Some quick notes first. There is only a drawing for the right stand...

Hoss,
Thanks a bunch it really means a lot.

bollero,
For 7200 I would go with a 16t and 32t pulley. Would need to calculate the right belt size though as there isn't any margin for error. ...

I have a modbus library for AVR's on google code some where. https://code.google.com/p/arduino-modbus-slave/ It's been a long time since I looked at it but it might give you a place to start.

Sure, will do. Might be a week or so before I can get to it, traveling the next few days for work. Very much doubt it is apples to apples versus a Hitachi drive but might get you in the right...

I'll post some pics and the plans for the mounts tonight when I get home. Though I wouldn't call it an issue since there isn't one. Its just a tight fit. The only problem it created for me was...

Yes. Modbus Master but RTU only. If you're only going to support one that is the best choice. Controls use the query and response format with CRC checking. The only thing I really don't like...

I just enabled the Modbus Input/Output and "modbus plugin supported". On previous projects I used the original Modbus configuration and VB script which was painfully messy. The new plugin plus...

The G0704's spindle motor was originally swapped with a treadmill motor using Hoss's plans and that worked okay for a while. After a few months the treadmill motor started to arc under load or high...

I am using the KL-6050s, 570oz N23s, and a 7.3A 48V power supply as well. After converting the X/Y axis to ball screws the motor tuning went from 100 ipm @ 4 ips^2 to 300 ipm @ 8 ips^2. When...
