Right now getting frustrated.

I purchased a Masso 18 months ago, now I set this up on a Plasma table using Gecko G201x drives.

Has worked perfectly well for 18 months.

Now with the new G3, connecting the G201x just doesn't work.

2.5 per revolution, 2000 ppr.

Step and direction were simulated, and the actual wiring is the same as I have used for 18 months, the ground then went to the Masso main 12 vdc supply.

With DeskCNC, I needed a 5 volt signal, with the early version of Masso, this was compromised by using the S+, D+ with a common to the ground main power supply to Masso., 12 vdc.

Now it doesn't figure that when both the Gecko and the TC6600 drive will not accept the format of F1 once saved and instigated.

And yet I was able to run the Gecko's by just connecting common to GROUND in the early version.

Cheers.

It's a problem when both drivers will not accept the logic.

TB6600, will not work either.

When connected as per Masso advise sheet.

thanks for the serial number and I have checked that your serial number does not have any current limiting resistors and the output circuitry is exactly the same as of G2 controllers.

If your wiring worked with G2 the exact same should work for G3 also, can you measure the voltage on one of the direction pins when the drive is connected to MASSO and when not connected?

Could you check to see if my unit "G3-5765" has the current limiting resistors?

Thanks.

24vdc to power the Gecko 201X driver.

In F3 screen, by pushing right arrow on the keyboard, X+ gets activated on screen.

X moves 0.01 per hit either way.

By using either left arrow or right arrow.

Zero voltage on X / D+ ( de-activated), when activated by keyboard ( screen X+ on ), zero voltage.

Cheers.

More voltage readings.

X axis - (D+ 0.16 v) (D- 3.8v) (S+ 3.58v) (S- 0.17v)

Similar on all connected axis, Y / Z / B.

Cheers.

I hope your not going to tell me that the new G3 Masso supplied does not have the bells and whistles as suggested above.

I paid $1200 + for an operation I thought would never let me down.

Based on past experience I had realised that even the Geckos would work in the same format as previously installed.

That is the reason for not getting the motors working first, I concerntrated on the THC I have put together.

I had to get the THC happening first.

This if by going by all information should work, it does in theory working on the F1 , F2, F3 screens.

Before any other involvement.

Cheers.

thanks @lilow for the voltage level info and they are as expected. the G3 you have has the exact same output circuit as the G2.

do you still have the G2, will you be able to measure the signal voltages on that?
 

lilow

Lilow
I sure will.

There has got to be something going here.

The G2 has an arc voltage measurement between 0.03 up and down on the divided voltage.

Works with the Gecko 201X drivers boards.

Will have the info tomorrow.

I volunteered to help you guys last year.

I thought you had it sorted.

Cheers.

If it helps I made this quick video earlier this year showing testing an axis. You should be seeing similar results.

As it turned out they had the maximum and minimum soft limit values around the wrong way so the axis wouldn't move the direction values couldn't change.

Cheers

@lilow let's see what results you get from the G2 tests but from our side the G2 and G3 outputs are exactly the same.

Voltage readings of original controller working in a Plasma cutter.
Serial No -2391

X axis
S+ 3.51v
S- 155mv
D+ 3.345
D- -3.94

Y axis
S+ 3.5
S- 153mv
D+ 3.36
D- -3.99

Z axis
S+ 153mv
S- 4.1
D+ 3.3
D- -4.04

All D+ and D- change from positive to negative values.

If you need any more info, let me know.

The Gecko that I was using works fine on a pulsar board.

Pulsar D changes from 4.56v to zero depending on direction.

The step voltage remains a constant 3.03vin both directions.

Cheers.

thanks, so the G2 and G3 voltages are the same and as expected.

now the drives are working with G2 but not G3 correct?

that is the strange bit, if the voltage is same then why would the drives not work. Can you measure the voltages on both G2 and G3 with drives connected, this will show the voltage drop with drives connected.

Masso support.

I just reconnected all power to the Masso and drivers.

Now it has a positive voltage on S+ 3.71v on xyz, before it was as stated in a previous post 0.15v.

After trying to make things work, swapping over drivers, motor, etc.

This S+ voltage has dropped to 1.71v.

This is telling me something after all these years.

When I swap the X to any axis that may move a readable dimension.

The X axis fails to do anything.

The Y only moves 1mm per plus or minus of the Y axis.

Can't get the Z to do anything, period.

So now believing the D+ and D- are swapping between positive and negative values.

I think we have a problem Heuston.

Cheers.

Masso.

The X axis S+ has now dropped to 1.47v since I last posted.

The imput voltage to the Masso is 11.87 vdc.

Cheers.
