CVI MachStdMill (MSM) / Disappointment

« on: July 18, 2010, 07:41:05 AM »

Disappointment yes, the screens look great but i just don't get the fact that you have to use the latest development version to use the screenset.

Sorry but i will not be bug testing the development version "Mach3 R3.043.10 "

Maybe someone can explain ?

Ok i will assume you have 12v to the input of the C6 board

Set the trimmer pot to the centre position

Set a least one pulley up that matches your maximum & minimum speed

UK ac is 50Hz i use the VFD at a max of 100HZ

My favourite speed on the lathe is 550 rpm at 50Hz now will go to 1100 rpm at 100Hz it is pulley seven of nine the minmum i use this pulley at is 275 rpm at 25HZ

Now you set your speed to maximum set up the spindle in motor tuning but the steps per and velocity are just made up numbers but while you are doing this i suggest you have the VFD disconnected

What you are aiming for is at your max speed you have 10v and at half speed you have 5v and so on

The thing that got my hair pulled out was i had to set the pulse with on the SS config page to 11.5 (us) you do not need PID numbers as i believe these are for servo systems.

Just keep adjusting the pulse width until you get close to 10v when almost there then you can use the trimmer

Then to test you set at half speed then measure voltage to make sure it is 5v then the  voltage slope should be linear

When you have got the voltage right then  connect the VFD

On my favourite pulley i am accurate to 2 rpm as i trimmed the pot to give a matching speed on a digital tacho.

I can't emphasize enough you must set at least one accurate pulley then you just set all your other pulleys accordingly.

I was using the default Mach3 steps per unit to perform the test. Thank you!

They mean the settings on the motor tuning page/tab

General Mach Discussion / Re: Hotkeys for buttons on screen...

As said I dislike hotkeys, Phill has pointed out one reason, another is you have to be extremely carefull that you dont assign a hotkey to more than one button function.

Hood

An advantage of MachScreen over Screen4 is that MachScreen throws an error if you map two buttons to one hotkey.

Just another god reason to not use Hotkeys then, eh Phil ? 

Hard not to agree, except Mach is supplied with HotKeys

Yes one of the reasons that Hood has a dislike for hotkeys is that you have to have the buttons enabled on every page you want to be able to Zero them

General Mach Discussion / Re: Tool radius not less than arc radius

« on: June 07, 2010, 06:14:27 AM »

can someone explain to me what do this mean (Tool radius not less than arc radius)
thats what comes up on the STATUS of my screen and also stops my machine form doing the part.

You are making a 50mm square pocket, in the corners you want a 3mm radius "ARC RADIUS" you set the program to run using a tool of 12mm diameter "6mm TOOL RADIUS"

Which is impossible, so you must use a smaller tool

« on: June 04, 2010, 12:07:53 PM »

Yes i see

You say you have backlash. How much on each axis ?

Are you using conventional or climb milling ?

OK thanks for the answers.

It seems a certain way to confuse and get a crash

For now i have solved the problem by adding 30 to tools with a different insert so T0303 becomes T3333 with a different insert

Have you got a tool offset enabled ?

In my version of the tool zero script i turn off all offsets
