General Mach Discussion / G31 causes driver fault

« on: February 23, 2016, 04:02:43 PM »

Hi,

I've just made my own digitizing probe and it works good for probing in the X, Y and Z direction with the 2010 screenset.

Today I tried to use the Digitizing Wizard, but we seem to have a problem here.

This is the data of my system:

Windows 7 SP1
CSMIO/IP-M
Leadshine AM882
Mach3 ver. R3.043.062
2010 Screenset
Setup for milimeters

Some of the code:

 (Digitize File)
M40
G92X0Y0Z0
F100
 G0X0Y0Z5
 G31 Z-6 (Probe touches the surface and outputs Hit success on the screen)

G0 Z5 (Now the driver goes into fault state when trying to read the G0 Z5 line.)
... 
M30

The driver has stall protection meaning that too much acceleration causes the driver to go into the fault state. I can verify this by periodic time of the red led that starts to flash on the driver. I changed the Z in the code to X and my machine made a very rapid move to G0 X5, after the G31 code. When I afterwards tried to run the code again, the driver vent into fault state, just like the Z-axis. This indicates that the code makes my system accelerate very rapid when trying to do the G0 move after the G31 move.

Here are the things I have tried to do, to narrow down the problem, but without success:

- Changed the X, Y and Z Velocity and Acceleration to very low values in Motor Tuning.
- Put G21 line between the  G31 and G0

Maybe it's some incompatibility between CSMIO and Mach3 (G31)?

I really hope that some of your guys can help me with this one.


Thank you in advance,

Brian

CS-Lab / CSMIO/IP-M, VFD calibration, Spindle pulleys, Mach3

Hello everyone.


I´m a happy owner of the CSMIO/IP-M (V2.700) but now I´m stuck with a small problem and I would like to hear if anyone have had the same issue.

The gearbox on my RF-45 clone has a total of 6 gear settings and to be able to use the gearbox in combination with my VFD (see zip'ed attachment), I have made 6 Pulley configs.

The problem is that the VFD does not scale at all to the pulleys. I can make it work by setting higher numbers, but I just wonder what is going on? CSMIO/IP-M outputs a far higher analog voltage to the VFD than it´s supposed to do.


Here are the numbers I have put in to make the VFD scale properly:

Pulley Number 1:
Max Speed = 1250 rpm (Real speed = 300 rpm)

Pulley Number 2:
Max Speed = 2145 rpm (Real speed = 520 rpm) 

Pulley Number 3:
Max Speed = 3750 rpm (Real speed = 850 rpm)

Pulley Number 4:
Max Speed = 7850 rpm (Real speed = 1800 rpm)

Pulley Number 5:
Max Speed = 13300 rpm (Real speed = 3200 rpm)
 
Pulley Number 6:
Max Speed = 22500 rpm (Real speed = 5000 rpm)


Maybe I need to change some settings in the VFD, but I can´t figure it out. I hope that some of you guys can help me.


Thanks in advance,

Brian, Denmark
