General Mach Discussion / Chinese motor controller
« on: February 28, 2016, 08:05:58 AM »
Hi guys
I've just had 3 Chinese motor controllers delivered , first one ran hot even with no load but then failed. The second ran cool but not as it should, i tried changing the micro step options then it failed as well. The third is running sweet, nice and cool and doing everything as it should.
Are these things a hit and miss item, is it a matter of buy cheap and take your chances?
Thanks, appreciate your thoughts.
Dave

General Mach Discussion / Huanyang vsd
« on: January 27, 2016, 04:36:47 AM »
Hi guys
A simple question about the huanyang vsd. I had i setup and running sweet, took the computer of the cnc and had it set up on another machine for a while. I've just hooked it all back up and the vsd turns the spinde on whn it should but only goes up to 7200 rpm when mach3 is telling it to go to 12000 rpm. Also doesn't change speed under mach3,  what setting do i eed to check..... a year ago i knew all these off the top of my head!

Hope someone can help.

Thanks Dave

General Mach Discussion / 4 & 6 motor
« on: May 25, 2015, 04:45:40 AM »
Hi all
I have a 6 wire motor that I've wired as 4 wire, just left off the 2 spare wires. Yellow and white.  (read this somewhere) motor runs fine but I don't think this is right as it has way more power than the same 4 wire motor and runs a lot hotter.

Have I got this wrong?

Thanks Dave

General Mach Discussion / A axis as spindle
« on: May 23, 2015, 08:37:31 AM »
Hi all,
I know this has probably been covered but I can't find what I need to make it work...... My cnc quilting machine only uses x and y axis and I want to use another stepper as a spindle motor so I've wired this to axis a. I've tried all sorts of settings but can't get it to work....

Can someone please talk me through the basic setups for this a axis as a spindle, drive is gecko g540.

Many thanks.

General Mach Discussion / Brain play.....
« on: April 10, 2015, 09:08:42 AM »
Hi all
Just started to have a look at the brain function and have a question. Mainly I can't find cycle start command in the brain editor list.

I want to have cycle start trigger output 1 and  stop (not estop) turn it off again.

At the moment I have a start in m code but if I hit stop,  it stops motor on output 1 but won't restart when I hit cycle start again.

I thought if I use the brain I could trigger output 1 from start cycle and stop buttons.

Once this is sorted id like to add a remote start stop button via inputs.

Appreciate any help on this.

Thanks Dave

General Mach Discussion / Spindle speed
« on: March 27, 2015, 05:40:22 AM »
Hi all

Is there anyway to link spindle speed to movement velocity?

I'm using mach3 to control a cnc quilting machine and now I'm going use the spindle to drive the sewing machine motor. Varying spindle speed along with motion speed varies the stitch length.

Ideally I'd like the spindle speed to increase ( or decrease) as the motion (x&y) speed increases.

I'm using another stepper as the spindle.
Also not sure about settings to get true rpm. Normal steppers are 200 per rev so do what settings do I us?

Possible?

Thanks Dave

General Mach Discussion / Mach 3 to drive a motor at fixed rpm
« on: January 29, 2015, 06:12:12 AM »
Hi all

I need to replace the drive motor on the cnc quilting machine i built for the wife, it doesn't have enough torque at the speed I need it to run.

What I'd like to do is use another stepper motor for the sewing machine and drive it from mach 3. I'm only using 2 axis at the moment so it would be easy to use the Z (or A) axis for this.

At the moment I do a M30 motor start to turn on the machine relay at the start of the sewing action, how do I turn on say the Z axis and leave it running until I send another motor stop command at the end of the process?

Thanks Dave
