General Mach Discussion / Re: Should I Earth the CNC Machine?

« on: July 24, 2015, 04:04:14 AM »

If everything is connected correctly it should have any earthing it requires, adding earth straps randomly can cure or cause problems but the answer is "It Depends" ;-) 
Details of make, model etc. might help folks form a useful opinion, my CNC mills are earthed by the 3 phase connection to the motor, the wiring shields are grounded at the controller end to it's enclosure but are not connected at the machine end,

It has wires between the computer and multi-axis board, even if you can only get cables with moulded plugs it's easy to swap two pin connections for testing purposes by splitting and metering out a spare cable and swapping the two required wire connections.

The step and dir signals to x,y,z,a axis are wired internally, and cannot be changed.

It has wires feeding into it though ;-)

You've swapped motors & wiring proving that's all good, now swap your inputs for A & Y to see if your fault follows a port pin or a hardware channel.

look up CAD

Or possibly CAM?

CAD is used to create the drawing or solid model,

CAM is used to generate G-Code from a drawing or solid model

You could always video the run and use a player with fast forward, rewind single step and freeze frame to review the live data

General Mach Discussion / Re: x & y axis. What is going on?

« on: June 28, 2015, 08:14:08 AM »

Mach3 doesn't think anything, it does what you tell it, your G-code defines the X and Y moves so you need to

change your machine definition in CAM
or
rotate the part 90 degrees in your CAD package
or
swap your axes in Mach3

If you define your zero in CAD/CAM you will know where to set it on your machine, if you're allowing the software to define a default zero you need to note where it is on the stock, you can then set Mach3's zero appropriately,

The demo runs with a limited number of lines of code for PP, not sure about with a motion controller but I can't see why not,

Not all modern parallel cards have the correct output voltage to drive all BOBs, check your card's output voltage and your BOB's requirement,

Nick,

I see your using demo for Mach3.

Not me Sir!
Bought a license I did Sir!
;-)

This is definitely the place for free support of second hand equipment .

My reflection as follows..................Yeah, buy whatever then expect everybody else to do the work a user.
Don't give any info or links or whatever as the communities time is without value, don't read TFM, shoot they can educate me,
and on and on and on...................Gets old, Nick! May be I am getting old!
 

What I really meant was that it's a great community where most experienced users do pitch in and try to help if they see a problem which they can help with, though a lot of the load is inevitably taken by the resident Gurus ;-)

ATB,
Nick
